In the related art, a method of installing a mechanical pressure sensor on a seat is generally used to detect the pressure applied to the seat, thereby detecting whether a user is present on the seat and detecting the number of users on the seat. However, the mechanical pressure sensor has a large volume and a hard material, and when the seat is in an irregular shape or the contact surface between the seat and the user is an arc surface, the mechanical pressure sensor cannot be well attached to the surface of the seat, so that the detected pressure is inaccurate.

In order to improve the accuracy of detection, the embodiment of the application provides a pressure detection module, a seat device and seat equipment, wherein the pressure detection module can be arranged in the seat device and can be tightly attached to different types of seat devices to form a seat device which can be used for detecting the number of users on the seat device so as to achieve the aim of improving the accuracy of detection.

Next, a seat device 1 provided in the present application will be described with reference to fig. 1.

Fig. 1 is a schematic cross-sectional view of a seating apparatus provided in an embodiment of the present application. As shown in fig. 1, the seat apparatus 1 includes: a seat body 11, a data processing module 12, and at least one pressure detection module 10.

The pressure detection module 10 is mounted on the seat body 11, the data processing module 12 is mounted on the seat body 11, and the pressure detection module 10 is electrically connected 12 with the data processing module.

Wherein the pressure detection module 10 transmits a plurality of pressure detection values to the data processing module 12; the data processing module 12 determines the number of pressure-detected objects on the seat apparatus 1 based on the plurality of pressure-detected values.

The seat device 1 may be a car seat, a bicycle seat, an electric car seat, a seat of amusement park facilities, or the like. The seating apparatus comprises a seating arrangement 1. Correspondingly, the seat device can be an automobile, a bicycle, an electric vehicle or amusement park facility, etc.

The seat body 11 may have various shapes, and the pressure detecting module 10 needs to be installed in the longitudinal direction of the seat body 11 to ensure that the pressure generated by the pressure detecting object can be uniformly detected.

Wherein the pressure detection module 10 can be mounted to the seat body 11 in various ways

As a possible way, the pressure detection module 10 is embedded in the seat body 11.

When the pressure detection object is a user, the pressure detection module 10 is embedded in the seat body 11 in consideration of comfort, and comfort when the user sits on the seat apparatus 1 is improved.

As another possible way, the first surface of the flexible flat plate 110 in the pressure detection module 10 is attached to the surface of the seat body 11 facing away from the pressure detection object.

The pressure detection module 10 is attached to the surface of the seat body 11 facing away from the pressure detection object, so that the distance between the pressure detection module 10 and the pressure detection object can be reduced to the greatest extent, the sensitivity of the detection unit 120 for detecting the pressure detection value can be improved, and the detection accuracy is further improved.

It can be seen that the pressure detection module 10 installed in the seat apparatus 1 can enable the pressure detection module 10 to be adapted to the seat body 11 with an irregular shape or to be closely attached to the seat body 11 with an arc surface on the surface, so as to improve the accuracy of detecting the pressure detection value, thereby improving the accuracy of determining the number of the pressure detection objects on the seat apparatus 1 by the data processing module 12 according to the plurality of pressure detection values.

Next, the pressure detection module 10 provided in the present application will be described with reference to fig. 2.

Fig. 2 is a schematic structural diagram of a pressure detection module according to an embodiment of the present application. As shown in fig. 2, a pressure detection module 10 provided in an embodiment of the present application includes: the flat plate 110 can be bent, and at least two detection units 120 and a data transmission interface 130 are arranged.

Wherein the foldable flat 110 is mounted to the seat apparatus 1. Because the flexible material of the flat plate 110 can be folded at will, when the flat plate 110 is mounted on the seat device 1, the flat plate can be adjusted according to the shape of the seat device 1, so that the flat plate can be tightly attached to the seat device 1, the detection unit 120 embedded in the flat plate 110 can be tightly attached to the seat device 1, and when a pressure detection object exists on the seat device 1, the detection unit 120 embedded in the flat plate 110 can accurately detect the pressure detection value.

The pressure detector may be a user (e.g., a robot and/or a human), an animal, an object, or the like.

Wherein, at least two detection units 120 are arranged at intervals along the length direction of the seat device 1. Since the contact surface of the pressure detecting object with the seat apparatus 1 may be narrow or small, or the pressure detecting object may be in contact with only one edge of the seat apparatus 1, when only one detecting unit 120 is provided in the seat apparatus 1, one detecting unit 120 may not detect the pressure, or the detected pressure may be inaccurate, so at least two detecting units 120 need to be provided in the seat apparatus 1 to ensure that the pressure detecting value can be accurately detected.

For convenience of description, the embodiment of fig. 2 herein takes the number of detection units 120 as 3 as an example.

In addition, at least two detection units 120 need to be arranged at intervals along the length direction of the seat device 1, and the contact area between the pressure detection module 10 and the pressure detection object can be increased, so that the detection units 120 can accurately detect the pressure detection value.

For example, when the seat apparatus 1 has a substantially triangular shape and the number of the detection units 120 is 3, the detection units 120 may be arranged as shown in fig. 3. For simplicity of illustration, the data transmission interface 130 and conductive lines are not shown in fig. 3.

Wherein, the detecting unit 120 is embedded in the bendable flat plate 110. The detection unit 120 is embedded in the foldable plate 110, so that the foldable plate 110 can serve as a carrier for the detection unit 120. The bendable flat plate 110 is mounted on the seat device 1, and the bendable flat plate 110 is made of soft material, so that the detection unit 120 can be attached to the surface shape of the seat device 1, and the detection accuracy of the detection unit 120 is improved.

Wherein the detecting unit 120 is provided with a detecting surface on the first surface of the bendable flat plate 110.

Wherein the first surface of the bendable plate 110 faces the pressure detecting object.

The data transmission interface 130 is disposed at one side of the foldable flat plate 110, the detection unit 120 is electrically connected to the data transmission interface 130 through a conductive wire, the conductive wire is embedded in the foldable flat plate 110, the data transmission interface 130 is electrically connected to the seat device 1, and the data transmission interface 130 is used for transmitting a plurality of pressure detection values collected by at least two detection units 120 to the seat device 1, so that the seat device 1 determines the number of pressure detection objects on the seat device.

In practical applications, when the pressure detection object generates pressure on the seat apparatus 1, the detection units 120 can collect pressure detection values generated by the pressure detection object, and the number of the pressure detection values is the same as the number of the detection units 120.

The following describes in detail a specific implementation procedure of the seat device 1 for detecting whether or not there are users and how many users are on the seat device 1, taking a pressure detection object as an example of the users.

For example, when the number of the detection units 120 is 2, the seat apparatus 1 can detect whether there is a user on the seat apparatus 1, and the number of users on the seat apparatus 1.

When the pressure detection values are both acquired by both the detection units 120 and the pressure detection value is greater than or equal to the preset threshold value, it may be determined that there are users on the seat apparatus 1 and the number of users on the seat apparatus 1 is 1.

When the pressure detection values are both acquired by both the detection units 120 and the pressure detection value is smaller than the preset threshold, it may be determined that there are no users on the seat apparatus 1 and the number of users on the seat apparatus 1 is 0.

When only one detection unit 120 of the two detection units 120 collects the pressure detection value, it can be judged that there is no user on the seat apparatus 1, and the number of users on the seat apparatus 1 is 0.

For example, when the number of the detection units 120 is greater than 2, the pressure detection values acquired by the respective detection units 120 are acquired, the trend of the pressure detection values in the longitudinal direction of the seat apparatus 1 is determined based on the plurality of pressure detection values and the positions of the respective corresponding detection units 120 on the seat apparatus 1, the presence or absence of a user on the seat apparatus 1 and the number of users on the seat apparatus 1 can be determined based on the trend of the pressure detection values in the longitudinal direction of the seat apparatus 1.

When the pressure detection value has monotony in the change trend in the longitudinal direction of the seat apparatus 1, it is determined that there are users on the seat apparatus 1, and the number of users on the seat is 1.

When the change trend of the pressure detection value in the longitudinal direction of the seat apparatus 1 is monotonously decreasing first and then monotonously increasing, it is determined that there are users on the seat apparatus 1, and the number of users on the seat apparatus 1 is 1.

When the change trend of the pressure detection value in the longitudinal direction of the seat apparatus 1 increases monotonically first and then decreases monotonically, it is determined that there are users on the seat apparatus 1, and the number of users on the seat apparatus 1 is greater than 1.

Therefore, the bendable flat plate 110 is made of soft material and can be bent at will, so that the bendable flat plate 110 can be adjusted according to the shape of the seat device 1, and the bendable flat plate 110 is tightly attached to the seat device 1, so that the pressure detection values can be accurately detected by the detection units 120 embedded in the bendable flat plate 110, and the pressure detection values can be accurately detected by the at least two detection units 120 which are arranged at intervals approximately along the length direction of the seat device 1.

In this way, when the pressure detection object generates pressure to the seat device 1, the detection unit 120 can collect the pressure detection value generated by the pressure detection object, and the data transmission interface 130 transmits the plurality of pressure detection values collected by the at least two detection units 120 to the seat device 1, so as to improve the accuracy of determining the number of the pressure detection objects on the seat device by the seat device 1.

Based on the description of the above embodiments, in some examples, the thickness of the bendable plate 110 is less than or equal to 0.3mm.

On the one hand, the thickness of the bendable flat plate 110 is ensured to be smaller than or equal to 0.3mm, so that the bendable flat plate 110 can be tightly attached to the surface of the seat device 1, and the accuracy of pressure detection of the detection unit 120 embedded in the bendable flat plate 110 is improved.

On the other hand, when the pressure detecting object is a user, considering that the thickness of the bendable flat plate 110 is too large to possibly affect the comfort, ensuring that the thickness of the bendable flat plate 110 is less than or equal to 0.3mm can improve the comfort of the user sitting above the seat apparatus 1.

Based on the description of the above embodiments, the pliable sheet 110 may take on a variety of implementations.

In some examples, the pliable sheet 110 is integrally formed.

Compared with an assembly part which needs to be assembled, the bendable flat plate 110 is integrally formed, so that the cost can be reduced, and the device is convenient to install in the seat device 1.

In other examples, the pliable sheet 110 is removably assembled from a plurality of mounting plates with at least two detection units 120 embedded therein.

One of the detecting units 120 may be embedded in one of the mounting plates, and at least two of the mounting plates are assembled into the bendable flat plate 110 during actual use, so as to obtain the pressure detecting module 10.

Compared with the integrally formed bendable flat plate, the bendable flat plate 110 is formed by detachably assembling a plurality of mounting plates, and at least two detection units 120 are embedded in the plurality of mounting plates, so that different numbers of detection units 120 can be selected to form the pressure detection module 10 according to different requirements. For example, when three detecting units 120 are needed to detect, and one detecting unit 120 is embedded in one mounting board, the three mounting boards may be assembled into the bendable flat board 110, so as to obtain the pressure detecting module 10.

In addition, in actual use, when the detecting unit 120 goes out of line, the user is convenient to overhaul, and the detecting unit 120 with faults is independently replaced, so that the cost can be saved.

Based on the description of the above embodiments, in some examples, the shape of the bendable flat plate 110 is substantially the same as the shape formed by enclosing at least two detection units 120.

As shown in fig. 3, when the number of the detecting units 120 is 3 and the shape formed by enclosing the detecting units 120 is substantially triangular, the shape of the bendable flat plate 110 may be triangular, and the area of the bendable flat plate is slightly larger than the triangle formed by enclosing the detecting units 120, so that the material for manufacturing the bendable flat plate 110 may be saved. Further, the detecting unit 120 embedded in the foldable flat plate 110 may also be made to fit the seat apparatus 1 more closely with the foldable flat plate 110.

In addition, the thickness of the foldable flat plate 110 is smaller, and the shape is approximately the same as the shape formed by enclosing at least two detection units 120, so that the volume of the foldable flat plate 110 is smaller, and the pressure detection module 10 is mounted on the seat device 1, so that the mounting space can be saved.

Based on the description of the above embodiments, in some examples, the material of the bendable plate 110 is a flexible material.

The flexible material has the characteristics of softness, random stretching or random bending, and the like. Therefore, the flexible material of the bendable flat plate 110 can improve the fitting degree of the bendable flat plate 110 and the seat device 1, and adapt to the seat device 1 with different surface shapes, thereby improving the detection accuracy of the detection unit 120 embedded in the bendable flat plate 110.

In addition, the flexible material also has the characteristics of light weight and thinness. Therefore, the flexible material of the flexible flat plate 110 can reduce the weight and volume of the pressure detection module 10, thereby reducing the weight and volume of the seat device 1 and saving the installation space.

Wherein the flexible material comprises polyvinyl chloride (polyvinyl chloride, PVC) plastic, polyvinyl alcohol (polyvinyl alcohol, PVA), polyethylene terephthalate (polyethylene glycol terephthalate, PET), polyimide (Polyimide, PI), graphene or the like.

Preferably, the flexible flat plate 110 is made of polyvinyl chloride (Polyvinyl chloride, PVC) plastic.

Since the PVC plastic has good mechanical properties and high tensile strength and impact strength, the durability of the pressure detection module 10 can be increased, and the PVC plastic has low cost and can also save production cost.

Based on the description of the above embodiments, the detection unit 120 may include various types.

In some examples, the detection unit 120 is a thin film pressure sensor.

The film type pressure sensor is composed of a small amount of materials, is compact in structure and convenient to install, is very sensitive to slight pressure change, can adapt to an application scene requiring accurate measurement of pressure detection values, and can detect very slight pressure change compared with a mechanical type pressure sensor which requires a minimum excitation pressure to acquire the pressure detection values, so that detection accuracy can be improved. In addition, the film type pressure sensor has a large measuring range, almost no limit of measuring range and a wider application range compared with a mechanical type pressure sensor.

In other examples, the detection unit 120 is a hall sensor.

The hall sensor is a solid-state device, has no moving parts, and therefore, does not generate friction or wear, and is hardly affected by vibration, dust, and water, and therefore, has a long service life compared with a thin film pressure sensor.

In other examples, the detection unit 120 is a displacement chip.

The displacement chip can convert the mechanical displacement into a resistance, voltage or current output in a linear or arbitrary functional relationship therewith via the potentiometer element, and can therefore be used to detect pressure. The displacement chip has stronger anti-interference capability, smaller volume, higher precision and more convenient installation, and can improve the detection precision of the detection unit 120.

In addition, the detection unit 120 may be a reed switch sensor or a magneto-resistive sensor, which is not limited in this application.

Based on the description of the above embodiments, in some examples, the area of the detection face is greater than or equal to the area of the first surface of the detection unit 120 projected onto the bendable plate 110.

In order to ensure the detection accuracy of the detection unit 120, the detection surface needs to cover the detection unit 120, and thus, the area of the detection surface needs to be greater than or equal to the area of the first surface of the detection unit 120 projected onto the bendable flat plate 110, thereby ensuring the detection accuracy of the detection unit 120.

Based on the description of the above embodiments, in some examples, the detection surface is circular in shape.

The shape of the detection surface is set to be circular, so that the pressure distribution can be more uniform when the pressure detection object generates pressure to the detection unit 120, thereby ensuring the detection accuracy.

Of course, the shape of the detection surface may be other than a circle, and this is not a limitation of the present application.

Those skilled in the art will appreciate that while some embodiments herein include certain features that are included in other embodiments, combinations of features of different embodiments are meant to be within the scope of the present application and form different embodiments. For example, in the claims, any of the claimed embodiments may be used in any combination.
