The function of changing the shape of the seat cushion and back cushion mainly appears on the car seat, which aims to provide effective support for the driver according to the constantly changing external force during driving, so as to adapt to different driving environments.

The Chinese patent document whose publication number is CN104055344A discloses an intelligent learning seat. The invention uses a sitting posture detection device to collect data of learners sitting in front of desks and chairs, and transmits the collected data to a data processing unit, which, after processing the collected data, transmits the processing results to the intelligent control device According to the data processing results, the intelligent control device controls the automatic adjustment device of tables and chairs to realize the movement of the seat, the automatic lifting of the desktop or the automatic tilting of the desktop or the automatic lifting of the chair surface or the automatic tilting of the chair back. The limitation of this learning seat is that it only provides overall structural dimensions such as seat depth and height, but cannot adjust the shape of the seat surface and back cushion. And these size adjustments are all available in general students. These adjustments are aimed at adapting to different body shapes of people, but cannot adapt to different sitting posture physiological forms.

The Chinese patent document with publication number CN102050038A discloses a method for dynamically adjusting the body support of a vehicle seat occupant based on the current vehicle speed and stored data about the current road direction. By pre-calculating a road that the vehicle is most likely to travel along during driving, each pre-calculated most likely road is longer than the end of the upcoming curve and can be adjusted when passing this curve Body support adapted to the entire pre-calculated most likely road to travel. The invention aims to solve the problem of seat support and wrapping during vehicle running. It adapts to the force of the driver under different driving conditions by dynamically adjusting the shape of the seat. The problem it solves is the riding stability of the driver during driving, not to reduce the fatigue caused by sitting for a long time.

Adolescents continue to develop physically as they grow older, and their body shape changes, especially in height and bone shape. When sitting, if the shape of the seat support part cannot well fit the body shape of teenagers of different ages, it will easily lead to fatigue, and may even lead to deformity of bone development.

Ordinary seats usually have a rigid seat frame, and then a soft covering is installed on the rigid seat frame, for example, a sponge is set under soft cloth or leather. Or, without a rigid seat frame, a chair or sofa made of foam particles. The shape of the seat is fitted to the shape of the body part through the deformation of the sponge or foam particles. A common seat with foam is an office chair. However, since the shape of the rigid seat frame is fixed and cannot be adjusted, it cannot be well matched to people of various body shapes, especially adolescents who are in the physical development period, making some people who are not suitable for the shape of the seat frame It is easy to cause fatigue. Common seats with foam particles are beanbags or beanbags. As soon as a person sits on it, the foam particles will be forced to move, and highly fit with the shape of the body parts. Lazy chairs or lazy sofas are particularly comfortable to sit on. But in fact, sitting on a thick and soft sofa is like sitting on a pile of loose sand. In fact, none of the muscles in the whole body is completely relaxed. Instead, the entire musculature is under abnormal tension and compression. Over time, it may lead to muscle strain, scoliosis, and induce cervical spondylosis and lumbar disc herniation. Therefore, in order to enable the seat cushion A and/or back cushion B to provide strong support according to different body shapes, the present invention adopts a changeable support form.

Preferably, the height of the support point 2 can be controlled to change the support form of the support block 1 corresponding to the corresponding support point 2 .

According to a preferred embodiment, each supporting point 2 can be moved and locked by an independent driving part 4 . The driving part 4 may be a first motor. Preferably, the first motor is a push rod motor. In this way, the support form of the pad can be changed more finely, which can improve comfort and prevent fatigue to a greater extent.

Example 4

A dynamically adjustable seat for teenagers according to the present invention, the seat surface and/or the back surface of the seat can adopt the dynamically adjustable cushion described in Embodiment 1, Embodiment 2 or 3.

According to a preferred embodiment, when a person gets up, the support block 1 can move a third distance toward the covering surface 7 driven by the support point 2 . Alternatively, when a person sits down, the support block 1 may move a third distance in a direction away from the covering surface 7 driven by the support point 2 .

According to a preferred embodiment, the first distance between the sitting surface and the ground can be adjusted. Adjusting the first distance can help people with different legs or heights find a suitable height, and prevent fatigue from being too low or too high.

According to a preferred embodiment, the second distance between the resting surface and the sitting surface can be adjusted. The second distance is adjustable so that the front and back positions of the seat cushion relative to the back cushion can be changed, so that users with different leg lengths can find a suitable sitting depth and improve sitting comfort.

Preferably, the up and down position of the cushion of the present invention on the rest surface can be adjusted. By adjusting the upper and lower positions of the cushion, the cushion can find a suitable lumbar support position for users of different body shapes, preventing the waist from being effectively supported and causing easy fatigue.

Preferably, the seated person can manually adjust the front and rear positions of the seat surface, the height of the seat, and the up and down positions of the backrest.

Example 5

This embodiment is a further improvement on Embodiment 4, and repeated content will not be repeated here.

On the seat of the present invention, the seat posture configuration is manually adjusted. The user sends a signal to the control module through the control button, and the control module sends a control command to each support module of the seat cushion A and back cushion B, and adjusts the height and position of each module until a suitable comfortable state is found.

Example 6

This embodiment is a further improvement on Embodiment 4 or 5, and repeated content will not be repeated here.

According to a preferred embodiment, the seat of the present invention further includes a seat frame. The seat frame can be made of various materials that can provide support. For example, stainless steel, plastic, carbon steel, carbon fiber, wood and aluminum.

According to a preferred embodiment, there are installation interfaces for control module lines, control modules, communication modules and other equipment on or within the seat frame. Preferably, the cushion A can be installed on the seat through the first sliding pair. Back cushion B can be installed on the seat through the second sliding pair. The seat cushion A and the seat support leg can be connected by a third sliding pair. The sliding directions of the first sliding pair and the second sliding pair intersect. The user can adjust the sitting depth of the cushion A through the first sliding pair. The user can adjust the height of the back cushion B through the second sliding pair. The user can adjust the height of the cushion A from the ground through the third sliding pair. Preferably, the included angle between the sliding directions of the first sliding pair and the second sliding pair is an obtuse angle, so as to provide a more comfortable seat shape.

According to a preferred embodiment, the pressure sensor and the driving part or the second motor in the seat cushion A and the back cushion B can be connected to the control module. The control module can be connected to the communication module. The communication module can be connected to an external wire control device through a control wire. The communication module can also be connected with an external mobile terminal through wireless communication. The mobile terminal is, for example, at least one of a smart phone, a smart bracelet, a smart watch, VR glasses, a computer, and a projection device. After the corresponding application program is installed on the mobile terminal, the shape of the seat can be adjusted. When the communication module is connected to a mobile terminal with health monitoring function, the control module can also collect the health monitoring information of the mobile terminal and combine the data collected by the pressure sensor in the seat cushion A and/or back cushion B to adjust the shape of the seat. In this way, a richer data source can be provided for the shape adjustment of the seat, and a good seat shape can be provided to the user more comprehensively and accurately. More preferably, after the communication module is connected to the mobile terminal, it can acquire the identity of the mobile terminal. After the user sits and completes the shape adjustment of the seat, the control module can associate the identity of the mobile terminal with the adjusted seat shape. And when connecting to the communication module through the mobile terminal with the corresponding identity mark later, the seat form is adjusted in advance according to the seat form associated with the identity mark of the mobile terminal. Preferably, the identity mark is information capable of representing the unique identity of the mobile terminal. Different mobile terminals can be distinguished through the identification of the mobile terminal. Taking a mobile phone as an example, the identity of the mobile phone can be at least one of IMIE number, UDID, SN, ICCID, MAC address, Bluetooth address and mobile phone card number. In this way, when the seat has multiple users, after the user connects to the communication module of the seat through the mobile terminal, the seat configuration can be adjusted in advance according to the historical data of the associated seat configuration. In this manner, not only can the time required for manually and/or automatically adjusting the shape of the seat be reduced each time, the efficiency can be improved, and a good experience can be provided for the user. Moreover, the number of times to adjust the shape of the seat with a load can be reduced, and the service life of the seat is improved.

Example 7

This embodiment is a further improvement on Embodiment 4, 5 or 6, and repeated content will not be repeated here.

According to a preferred embodiment, the seat cushion A may be provided with a supporting structure, a sensor, a package filling material and a lower supporting frame 8 for realizing the shape transformation of the seat surface. Multiple rows of movable support groups can be fixed in the support frame 8 . The support structure is covered with a soft covering, especially the surfaces that come into direct contact with the user's body parts. The interior wrapped by the seat cushion A is composed of at least three support blocks. Each support block is a group of support structures with different shapes to realize the shape transformation of the seat surface. The movable support group has a plurality of movable support points. The control module is connected to the driving part of the corresponding support point, and when the seat shape needs to be adjusted, the control module sends a signal to control the driving part to adjust the height. By using the height difference between each support point and the resulting angle change, each row of support groups can form a different height curve, and multiple rows of support groups can realize the different top surface shape transformation of cushion A, so as to maintain the The shape of the user's buttocks fits different situations.

Multiple movable support groups realize the distribution of the overall seating surface points through the arrangement position in the assembly. Each movable support group is composed of a second motor, a rotating shaft and multiple cam support mechanisms. Preferably, the second electric machine is a torque motor. Each cam supporting mechanism is linked with the rotating shaft, and the torque motor receives the electric control signal to drive the rotating shaft to rotate at a certain angle, so that the height of the supporting surface of each cam supporting structure is sent to change. The second motor of each movable support group can be individually controlled by the control module. That is, different second motors can rotate at different angles according to different control signals, so as to respectively realize the shape change of the single-row supporting groups associated therewith.

According to a preferred embodiment, each cam supporting mechanism is composed of a cam fixed on the rotating shaft, a universal joint, a push rod and a supporting block. The support block is a disc or an ellipse. When the rotating shaft rotates, the cam will rotate at different angles along with the rotating shaft, and drive the push rod and the supporting block to produce height changes. The support block and the push rod are connected by a universal joint, so the orientation of the support block changes with the external force. In this way, through the universal joint, the orientation of the support block can be changed according to the user's body shape, preventing the edge of the support block from causing foreign body sensation to the sitting user due to inability to rotate, and improving comfort and user experience. At the same time, it also prevents the large impact on the covering surface during the adjustment process due to the inability to adjust the direction of the support block, prevents premature damage to the covering surface, and improves the reliability and service life of the seat.

According to a preferred embodiment, the inner structure of the seat cushion A and the back cushion B is the same. However, when the supporting blocks in the seat cushion A and the back cushion B are in the same initial state, the configuration curves of the covering surfaces of the seat cushion A and the back cushion B are different. That is, the first curved shape of the covering surface of the seat cushion A may be different from the second curved surface shape of the covering surface of the back cushion B, so as to provide strong support for the buttocks and the waist respectively.

According to a preferred embodiment, the control module can collect control requests from dedicated remote controllers, dedicated wire controllers and external mobile terminals, and obtain control instructions based on the pressure data collected by the pressure sensor and internal algorithm logic operations to adjust the shape of the seat .

Example 8

This embodiment is a further improvement on Embodiment 4, 5, 6 or 7, and repeated content will not be repeated here.

According to a preferred embodiment, the seat may also be provided with a weight sensor for detecting body weight. Preferably, the weight sensor is connected to the control module 9 . The control module 9 can collect the weight of the user and associate it with the corresponding user. The installation position of the sensor is preferably between the cushion and the ground. For example, provided within a support assembly that supports a cushion.

According to a preferred embodiment, the control module 9 can collect the pressure data of each pressure sensor in the pad. The control module 9 can adjust the position of the support point 2 to actively change the user's posture when the ratio of the maximum pressure to the minimum pressure in each pressure sensor exceeds the first threshold and its duration exceeds the second threshold. In this manner, it is possible to prevent the user from sitting for a long time in a posture with unbalanced sitting pressure, so as to reduce the fatigue of the user.

According to a preferred embodiment, the control module 9 can count the first pressure data set of the pressure sensor located on the left side of the sitting direction and the second pressure data set of the pressure sensor located on the right side of the sitting direction when the user is sitting in a periodical manner. And when the ratio of the first average pressure of the first pressure data set to the second average pressure of the second pressure data set exceeds the third threshold for a second preset duration, it is judged that the user has the intention to put the left leg on the right leg the first bad posture and record the first duration of the first bad posture. Or, when the ratio of the first average pressure of the first pressure data set to the second average pressure of the second pressure data set is lower than the fourth threshold for a second preset duration, it is judged that the user has put his right leg on his left leg The second bad posture and record the second duration of the second bad posture. The control module 9 can send the statistical data of the first bad posture and the second bad posture to the mobile terminal, and the mobile terminal reminds the user of the adverse consequences that may be caused by adopting the corresponding bad posture for a long time according to the obtained data. In this way, it is convenient for the user to check his bad posture later and make corresponding adjustments.

According to a preferred embodiment, the control module 9 can count the waveform of the pressure data measured by the pressure sensor on the seat cushion when the user is sitting, and judge that the user has a third leg shaking when the corresponding waveform repeats beyond the first preset frequency. bad posture and record the third duration of the third bad posture. The control module 9 can send the statistical data of the third bad posture to the mobile terminal, and the mobile terminal reminds the user of the adverse consequences that may be caused by adopting the corresponding bad posture for a long time according to the obtained data. In this way, it is convenient for the user to check his bad posture later and make corresponding adjustments.
