Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment, in particular to a sitting posture detection device and a learning machine. Background Art

[0002] Currently, learning machines are equipped with sitting posture detection devices to detect whether the user's sitting posture is correct and whether the user is concentrating when using the learning machine, and give timely reminders to help users correct their sitting posture and maintain an efficient learning state.

[0003] The common sitting posture detection camera of a learning machine is a fixed assembly with a fixed position and angle, so the shooting range of the sitting posture detection is also fixed. However, since the learning machine is also equipped with a finger-reading function, the learning machine needs to be placed at a fixed height and tilted at a fixed angle with the help of a matching bracket when in use, otherwise the finger-reading function will be affected. After the learning machine is tilted as a whole, the sitting posture detection camera will also tilt synchronously, so its viewing angle will also tilt upwards, and the user's hands may no longer be captured below the viewing angle, which will affect the user's posture detection effect. Utility Model Content

[0004] In view of this, the utility model is dedicated to providing a sitting posture detection device, which prevents the inclination of the carrier of the sitting posture detection device from affecting the posture detection effect of the sitting posture detection device by setting an inclination detection component and a driving component. In addition, the utility model also provides a learning machine including the above-mentioned sitting posture detection device.

[0013] Preferably, it further comprises a limiting member, which is arranged on a carrier of the sitting posture detection device and is used to limit the rotation angle of the shooting component when it is reset.

[0014] Preferably, the tilt detection component is a gyroscope.

[0015] A learning machine, comprising:

[0016] A housing, and a screen connected to the housing;

[0017] A sitting posture detection device, which is the aforementioned sitting posture detection device;

[0018] The shell and the screen cooperate to form an assembly cavity, and the sitting posture detection device is arranged in the assembly cavity.

[0019] Preferably, a light-transmitting area is provided on the screen at a position corresponding to the sitting posture detection device, and the light-transmitting area is distributed in the shooting angle range of the detection camera, so that the sitting posture detection device can detect the sitting posture of the human body.

[0020] Preferably, the light-transmitting area is configured as a long strip.

[0021] Preferably, the sitting posture detection device includes a limiting member, and the limiting member is the shell.

[0022] Preferably, a finger-reading camera is included, and the finger-reading camera and the detection camera of the sitting posture detection device are arranged at a distance.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] First of all, it should be noted that the sitting posture detection device in the present invention is suitable for scenarios where the user's sitting posture needs to be detected. For example, it can be set in a learning machine to detect the user's sitting posture when using the learning machine, or it can be set on a table to detect the user's sitting posture when working or studying.

[0034] like Figure 1-Figure 2 As shown, the sitting posture detection device in the embodiment of the utility model includes a driving component 1, a shooting component and an inclination detection component, wherein the driving component 1 is in transmission connection with the shooting component so that the driving component 1 can drive the shooting component to move or rotate; the inclination detection component is used to detect the inclination angle of the shooting component and is in communication connection with the driving component 1; it should be pointed out that the inclination angle of the above-mentioned shooting component refers to the angle of rotation of the shooting component compared to the initial position after the carrier 10 of the sitting posture detection device (a structure for installing the sitting posture detection device, for example, it can be a learning machine or a desktop of an office desk, etc.) moves. As for the initial position of the shooting component, it refers to the position of the shooting component relative to the carrier 10 of the sitting posture detection device before the carrier 10 of the sitting posture detection device moves and when the shooting range of the shooting component meets the detection requirements of the sitting posture detection device.

[0035] When the above-mentioned sitting posture detection device is used to detect the sitting posture of a human body, the inclination detection component detects the inclination angle of the shooting component. Thereafter, the driving component 1 adjusts the shooting angle of the shooting component according to the detection result of the inclination detection component to adjust the shooting range of the shooting component to the preset shooting range (the preset shooting range here refers to the shooting range of the shooting component when the sitting posture detection device can normally detect the sitting posture of a human body).

[0036] Figure 3 The figure shows the change in viewing angle of the shooting component of the sitting posture detection device before and after the angle adjustment after the carrier 10 of the sitting posture detection device is tilted, as shown in the figure, wherein the dotted line represents the viewing angle range before the angle adjustment of the shooting component, and the solid line represents the viewing angle range after the angle adjustment of the shooting component. In addition, the range indicated by area a in the figure is the preset shooting range of the shooting component, that is, the shooting range of the shooting component should at least include the range indicated by area a, so as to collect complete human sitting posture information and provide accurate human sitting posture monitoring. As shown in the figure, when the carrier 10 of the sitting posture detection device is tilted, the shooting range of the shooting component will deviate from the preset shooting range (causing the area indicated by area b to be unable to be monitored by the shooting component), which in turn causes the sitting posture detection device to be unable to collect complete sitting posture information, resulting in a reduction in analysis conditions, making it difficult to provide accurate sitting posture monitoring for users. The shooting angle of the shooting component in the sitting posture detection device in the present invention can be adjusted with the assistance of the driving component 1 and the inclination detection component. In this way, when the carrier 10 of the sitting posture detection device is tilted, the shooting angle of the shooting component can be adjusted so that the shooting range of the shooting component at least includes the area indicated by area a, thereby ensuring that the sitting posture detection device can operate normally, thereby avoiding the influence of the inclination of the carrier 10 (such as a learning machine) of the sitting posture detection device on the posture detection effect of the sitting posture detection device.

[0037] In some embodiments, the inclination detection component in the sitting posture detection device is arranged on the shooting component, so that the inclination detection component can monitor the inclination state of the shooting component at any time, thereby improving the accuracy of the angle adjustment of the shooting component. Specifically, when the carrier 10 of the sitting posture detection device drives the sitting posture detection device to tilt, the inclination detection component can directly detect the angle of inclination of the shooting component compared to the initial position, and when the inclination angle of the shooting component is adjusted by the driving component 1, since the inclination detection component is arranged on the shooting component, its detection data about the inclination angle will change in real time with the angle adjustment process of the shooting component. In this way, when the inclination angle of the shooting component is adjusted by the driving component 1, the angle adjustment of the shooting component can be learned by observing the detection data of the inclination detection component, thereby ensuring the accuracy of the angle adjustment.

[0038] In other embodiments, the inclination detection component is disposed on the carrier 10 of the sitting posture detection device. With such a configuration, when the carrier 10 of the sitting posture detection device drives the sitting posture detection device to tilt, the inclination detection component directly detects the inclination of the carrier 10 of the sitting posture detection device, and based on this, indirectly obtains the inclination angle of the shooting component. Thereafter, the driving component 1 adjusts the shooting angle of the shooting component according to the detection result of the inclination detection component, so as to adjust the shooting range of the shooting component to a preset shooting range. Compared with the above-mentioned embodiment in which the inclination detection component is disposed on the shooting component, the configuration method in this embodiment in which the shooting component and the inclination detection component are separately disposed can reduce the requirements of the sitting posture detection device for the assembly space compared to configuring the two as one.

[0039] Of course, in some other embodiments, a plurality of inclination angle detection components may be respectively disposed on the photographing component and the carrier 10 of the sitting posture detection device.

[0040] In addition, regarding the driving component 1, it can be a linear driving structure, such as an electric push rod, or a rotation driving structure, such as a motor, etc. The utility model does not make any specific restrictions on this, as long as it can drive the shooting component to change the tilt angle. Exemplary:

[0041] In some embodiments, the driving assembly 1 is a rotation driving structure. Figure 1 and Figure 2 As shown, the shooting component includes a rotating bracket 4 and a detection camera 5, wherein the rotating bracket 4 is transmission-connected to the driving component 1, and the camera is arranged on the rotating bracket 4; when the sitting posture detection device detects the sitting posture of the human body, the driving component 1 drives the rotating bracket 4 to rotate to adjust the shooting area of ​​the camera.

[0042] In other embodiments, the driving component 1 is a linear driving structure. In this case, the shooting component includes a rotating bracket 4 and a detection camera 5, wherein one end of the rotating bracket 4 is hinged to the carrier 10 of the sitting posture detection device, and the output end of the linear driving structure is hinged to the other end of the rotating bracket 4, and the linear driving structure can be rotatably set on the carrier 10 of the sitting posture detection device. In this way, when the sitting posture detection device is detecting the sitting posture of the human body, the rotating bracket 4 can rotate around the hinge point between it and the carrier 10, thereby adjusting the shooting area of ​​the camera.

[0043] In addition, on the basis that the inclination angle detection component is arranged on the carrier 10 of the sitting posture detection device, as shown in FIG. Figure 1 and Figure 2As shown, the sitting posture detection device also includes a limiter 3, which is arranged on the carrier 10 of the sitting posture detection device and is used to limit the rotation angle of the camera assembly during resetting; as mentioned above, when the inclination detection assembly is arranged on the carrier 10 of the sitting posture detection device, since the inclination detection assembly cannot directly detect the inclination angle of the camera assembly, the camera assembly needs to be controlled to return to the initial position after the sitting posture detection is completed, so as to facilitate the next adjustment. The setting of the limiter 3 can prevent the camera assembly from rotating excessively during the resetting process, and further ensure that the camera assembly accurately returns to the initial position during the resetting process.

[0044] Furthermore, in a preferred embodiment, a pressure sensor is provided at the position of the limit member 3 in contact with the shooting component, and the pressure sensor is communicatively connected with the driving component 1. Thus, during the resetting process of the shooting component, when the pressure detected by the pressure sensor reaches a threshold value, the driving component 1 stops, and at this time the shooting component just returns to its initial position.

[0045] The tilt detection component is a component in the prior art that can detect the tilt. For example, in some embodiments, the tilt detection component is a gyroscope; in other embodiments, the tilt detection component is a tilt sensor.

[0046] Furthermore, the sitting posture detection device in the present invention further includes a controller (such as a control circuit board 2), which is connected to the driving component 1. Figure 1 and Figure 2 The tilt detection component shown is provided with a joint 6, which is connected to the controller through the joint 6, and the controller can receive and analyze the angle information transmitted by the tilt detection component. Figure 4 As shown, the control logic of the controller in the embodiment of the utility model is as follows:

[0047] Control the shooting component to be in the initial position; then, determine whether sitting posture detection is needed, if not, maintain the shooting component in the initial position; if necessary, control the inclination detection component to detect the inclination angle of the shooting component, and command the driving component 1 to drive the shooting component to rotate the corresponding angle, so that the shooting component is in a flipped state, and adjust the shooting range of the shooting component to the preset shooting range; then determine whether sitting posture detection is needed, if still needed, keep the shooting component in the flipped state, if not needed, control the inclination detection component to detect the inclination angle of the shooting component, and command the driving component 1 to drive the shooting component to rotate the corresponding angle to put the shooting component in the initial position.

[0048] In addition, the embodiment of the utility model further provides a learning machine, including a housing 9, a screen and the above-mentioned sitting posture detection device, wherein the housing 9 and the screen are connected, and the two cooperate to form an assembly cavity, and the sitting posture detection device is arranged in the assembly cavity. It should be noted here that since the learning machine in the utility model includes the above-mentioned sitting posture detection device, the beneficial effects brought about by the sitting posture detection device on the learning machine are discussed in detail above and will not be repeated here.

[0049] like Figure 5 and Figure 6 As shown, a light-transmitting area 7 is provided at the position of the screen corresponding to the sitting posture detection device, and the light-transmitting area 7 is distributed in the shooting angle range of the detection camera 5 to avoid the silk-screen printing area of ​​the screen blocking the camera of the sitting posture detection device, thereby ensuring that the sitting posture detection device can accurately detect the sitting posture of the human body and ensure its normal operation.

[0050] The shape of the light-transmitting area 7 can be adaptively designed as needed. For example, in a preferred embodiment, the light-transmitting area 7 is set to be a long strip, so that it is ensured that the screen printing area will not block the camera of the sitting posture detection device, and at the same time, the influence of the setting of the sitting posture detection device on the screen display is reduced. Of course, in some other embodiments, the light-transmitting area 7 can also be set to be circular or special-shaped.

[0051] As mentioned above, based on the fact that the inclination detection component is arranged on the carrier 10 of the sitting posture detection device, the sitting posture detection device includes a limit member 3. In a preferred embodiment, the shell 9 of the learning machine is used as the limit member 3 to prevent the shooting component from leaning back when resetting. This setting method simplifies the structure of the sitting posture detection device.

[0052] Further, such as Figure 5 As shown, the learning machine includes a finger-reading camera 8, and the finger-reading camera 8 is spaced apart from the detection camera 5 of the sitting posture detection device. In this way, when the finger-reading function of the learning machine is used, the accessories used to assist in realizing the finger-reading function can be directly assembled at the corresponding position of the finger-reading camera 8 without affecting the normal operation of the sitting posture detection device.

[0053] The basic principle of the present invention is described above in conjunction with specific embodiments. However, it should be pointed out that the advantages, strengths, effects, etc. mentioned in the present invention are only examples and not limitations, and it cannot be considered that these advantages, strengths, effects, etc. must be possessed by each embodiment of the present invention. In addition, the specific details disclosed above are only for the purpose of illustration and ease of understanding, not limitation, and the above details do not limit the present invention to be implemented by adopting the above specific details.

[0054] It should also be noted that in the device, apparatus and method of the present invention, each component or each step can be decomposed and / or reassembled, and such decomposition and / or reassembly shall be regarded as an equivalent solution of the present invention.

[0055] The above description of the disclosed aspects is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these aspects will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other aspects without departing from the scope of the present invention.
