The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the utility model, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
The relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
As shown in fig. 1, the embodiment of the present application provides a sitting posture reminding device, which specifically includes: a first structure 101 and a second structure 102, wherein two ends of the first structure 101 are connected to the second structure 102 through two rotational connection structures 103, so that the first structure 101 can rotate relative to the second structure 102 around a central axis 104, which is a straight line passing through centers of the two rotational connection structures 103; a distance detection unit 105 and a counterweight 106 are arranged in the first structure 101, and the counterweight 106 is matched with the two rotary connecting structures 103, so that the detection angle of the distance detection unit 105 keeps a preset angle (such as a horizontal angle); the second structure 102 is provided with a clamp structure 107, and the opening direction of the clamp structure 107 is vertical and far away from the central axis; a reminding unit 108, communicatively connected to the distance detecting unit 105, configured to send out a reminding message when the distance detected by the distance detecting unit 105 is smaller than a preset distance, where the reminding unit 108 is disposed on the first structure 101 or the second structure 102.
The preset angle may be a horizontal angle, or an angle within a preset included angle range including the horizontal angle. The horizontal angle refers to an angle perpendicular to the gravity direction in a natural environment.
In the above embodiment, the clip structure 107 on the second structure 102 is used to fix the device on a target reading material (such as a mobile phone, a tablet computer, or a paper book, etc.), two ends of the first structure 101 are connected to the second structure 102 through two rotating connection structures 103, so that the first structure 101 can rotate relative to the second structure 102 with a connecting line of centers of the two rotating connection structures 103 as a central axis 104, and simultaneously cooperate with the weight block 106, so that when the target reading material is at different inclination angles, the distance acquisition unit can keep acquiring at a preset angle (such as a horizontal angle) under the action of gravity. In most occasions, the user places the reading materials right in front of the body for reading, so the distance acquisition unit keeps acquiring at a horizontal angle, the device can detect the distance between the user and the target reading materials at different target reading material inclination angles, and prompt information is sent when the distance is too close.
Optionally, the first structure 101 is a cylindrical structure, and the two ends of the first structure 101 refer to center points of two bottom surfaces of the cylindrical structure. The central axis 104 coincides with the central axis 104 of the cylindrical structure. The distance detecting unit 105 is disposed on a side surface of the cylindrical structure, and a detecting direction of the distance detecting unit is perpendicular to the central axis 104 and is far away from the central axis 104. By the embodiment, the overall profile of the device can not be greatly changed when the first structure 101 and the second structure 102 rotate relatively, and the influence of the overall profile change of the device on the appearance is avoided.
For convenience of illustration, it is agreed in the present document that when the detection angle of the distance detection unit 105 is a horizontal angle (i.e., an angle perpendicular to the gravity direction) and the position of the weight 106 is lower than the distance detection unit 105, the detection direction of the distance detection unit 105 is the front of the first structure 101.
It should be noted that the weight block 106 matches with the weight distribution of other components of the first structure 101, so that the detection angle of the distance detection unit 105 is a horizontal angle under the action of natural gravity. The weight 106 may be a structure made of a material with a relatively high density such as metal and having a function of only a counterweight, or may refer to a component having a function other than a counterweight, such as a battery, in the first structure 101.
Optionally, an inner cavity is disposed in the second structure 102, the first structure 101 is disposed in the inner cavity, the second structure 102 is a half-surrounding structure, and when the opening direction of the clip structure 107 is downward, the second structure 102 can cover the rear side of the first structure 101, so that when the target reading is on a plane, the first structure 101 does not directly contact the plane, thereby avoiding an influence on the detection direction of the distance detection unit 105 in the first structure 101.
The reminding unit 108 may be disposed in the first structure 101 or the second structure 102. Furthermore, a battery is also arranged in the device. The battery may be provided in the first structure 101 or in the second structure 102. If a battery is disposed in the first structure 101 and the reminder unit 108 is disposed in the second structure 102, the reminder unit 108 can obtain power from the battery through a power cord that is connected to the inside of the first structure 101 through the center of the rotational connection structure. If a battery is provided in the second structure 102, the distance detection unit 105 may obtain power from the battery through a power line connected to the inside of the second structure 102 through the center of the above-mentioned rotational connection structure.
Optionally, as shown in fig. 2, the apparatus further includes: an angle fixing structure 201, wherein the angle fixing structure 201 is used for stopping the relative rotation between the first structure 101 and the second structure 102 when the first structure 101 rotates to a specific position relative to the second structure 102.
The specific angle is a position of the portion of the second structure 102 where the clip structure is disposed and the distance detection unit 105 within a preset distance range. In an actual scenario, when the target reading material is placed on a plane (such as a desktop) for reading, or the target reading material is held by a hand to approach a horizontal use angle, the user's eyes are located obliquely above the target reading material, and therefore, in this case, if the target detection unit continues to perform detection by keeping a preset angle (such as a horizontal angle), the distance between the user's eyes and the target reading material cannot be accurately detected. When the target reading material is placed on a plane or at a nearly horizontal use angle, the edge region of the second structure 102 where the clip structure 107 is disposed will be close to the distance detection unit 105, and the angle fixing structure 201 will stop the relative rotation between the first structure 101 and the second structure 102, i.e. when the user will raise the detection angle of the distance detection unit 105 to make it detect obliquely upward. Therefore, the distance between the human eyes and the target reading material can be accurately detected under the condition.
Optionally, the angle fixing structure 201 is a magnetic attraction structure, and includes a first magnetic attraction structure and a second magnetic attraction structure, which are respectively disposed on the first structure 101 and the second structure 102, and when the first structure 101 rotates to a specific position relative to the second structure 102, the first magnetic attraction structure and the second magnetic attraction structure attract each other to stop the relative rotation between the first structure 101 and the second structure 102, so that the first structure 101 and the second structure 102 keep fixed relative positions.
Optionally, the angle fixing structure 201 is a protruding structure disposed within a preset distance from the distance detecting unit 105, and the protruding structure is configured to catch the second structure 102 when the second structure 102 rotates to approach the distance detecting unit 105, so as to stop the relative rotation between the first structure 101 and the second structure 102. Further, the clip structure 107 is disposed at an edge region of the second structure 102.
It should be noted that the magnetic attraction structure and the protrusion structure both automatically fix the first structure 101 and the second structure 102 when the first structure 101 rotates to a specific position relative to the second structure 102, and optionally, the angle fixing structure 201 may also be a manual fixing structure, such as an adjustable structure disposed on the first structure 101 or the second structure 102, the adjustable structure may be fixed at the first position and the second position, when fixed at the first position, the adjustable structure disposed on the first structure 101 abuts against the second structure 102, or the adjustable structure disposed on the second structure 102 abuts against the first structure 101, so that the two structures stop rotating relatively, when fixed at the second structure, the first structure 101 and the second structure 102 may rotate relatively freely. The above solution, or other solutions with the same function as the above solution, may allow the user to decide where to fix the first structure 101 and the second structure 102. In practical situations, since the situation that the first structure 101 and the second structure 102 need to be fixed is mainly when the target reading material is read on a plane (such as a table top) as described above, or when the target reading material is held to a usage angle close to horizontal, that is, the purpose of setting the manual fixing structure is also "stopping the relative rotation between the first structure 101 and the second structure 102 when the first structure 101 rotates to a specific position relative to the second structure 102" as described in this application, the embodiment of the manual fixing structure should also be within the scope of this application.
Optionally, the apparatus further comprises: a position adjustment structure 202 for adjusting the position of the protruding structure on the surface of the first structure 101. The position adjusting structure 202 may be a rotatable ring sleeved or spliced at one end of the first structure 101, the protruding structure is disposed on the position adjusting structure 202, and the relative positions of the protruding structure and the distance detecting unit 105 can be adjusted by rotating the position adjusting structure 202, so that the detecting angle of the distance detecting unit 105 can be adjusted when the target reading is placed on a plane, so as to meet the requirements of users with different heights.
Optionally, the distance detection unit 105 is an infrared distance detection unit or an ultrasonic distance detection unit. It should be noted that the distance detection unit 105 includes a transmitting end and a receiving end, and the transmitting end and the receiving end may be disposed in an opening on the surface of the same first structure 101, or may be disposed in openings on the surfaces of two first structures 101, respectively.
Optionally, the two rotating connecting structures 103 are damping rotating connecting structures 103.
It should be noted that, because the first structure 101 and the second structure 102 are rotatably connected, and the weight block 106 is disposed in the first structure 101, when a user adjusts an angle of a target reading, the first structure 101 may shake relative to the second structure 102, so as to affect a distance detection effect of the distance detection unit 105. Therefore, the rotation connecting structure 103 is configured as a damping rotation connecting structure 103, and the shaking of the first structure 101 relative to the second structure 102 can be effectively avoided.
Optionally, the reminding unit 108 includes: and a light-emitting reminding module. The light-emitting reminding module can emit monochromatic flickering reminding light or multicolor conversion reminding light. Optionally, the light-emitting reminding module is disposed on the first structure 101, and a light-emitting direction of the light-emitting reminding module is the same as a distance detection direction of the distance detection unit 105. Since the detection direction of the distance detection unit 105 is the direction of the eyes, the above embodiment can cause the light emitted by the light-emitting reminding module to directly irradiate the eyes to cause discomfort to the user, so that the user can immediately adjust the user to a correct sitting position when the eyes are too close to the target reading material.
Optionally, the reminding unit 108 includes: and a sound reminding module.
Optionally, the reminding unit 108 may only have a light-emitting reminding module or only have a sound reminding module, or both.
Optionally, the apparatus further comprises: and the recording unit 203 is in communication connection with the sound reminding module, and plays the recording audio collected by the recording unit 203 when the sound reminding module sends reminding information.
