Referring to fig. 1-2, in one embodiment of the present invention, a sensing handrail is provided, including:
the armrest body 100 includes a connecting section 110, a first supporting section 120 and a second supporting section 130, wherein the first supporting section 120 and the second supporting section 130 are respectively connected to two ends of the connecting section 110, and both the first supporting section 120 and the second supporting section 130 extend away from the same side of the connecting section 110;
a first fixing seat 200 for fixing the first supporting section 120, wherein a position where the first supporting section 120 is fixed is a fulcrum 210;
a second fixing seat 300 for mounting the second supporting section 130, wherein the second supporting section 130 can move up and down to match with the second fixing seat 300;
a state sensor, coupled to the free end of the second support section 130, for monitoring the upward and downward movement state of the second support section 130;
and the processor is connected with the state sensor and receives the sensing signal of the state sensor.
In this document, the three-dimensional directions of the armrest body 100 are a length direction (a connecting direction of the first support section 120 and the second support section 130), a height direction (a length direction of the second support section 130 or the first support section 120), and a thickness direction. In the present embodiment, the sensing armrests and the bed body are adapted as an example, and in other embodiments, the sensing armrests and the bed body can be adapted to the arrangement of a reclining chair-like instrument. The sensing handrail is not limited to be fixed on the bed body through the first fixing seat 200 and the second fixing seat 300; and the bed also can be provided with a base belonging to the bed body, and the sensing handrail is placed at the side of the bed body at the moment.
In this embodiment, the armrest body 100 is U-shaped, and the first support section 120 is close to the front of the bed. For example, the status sensor is disposed between the free end of the second supporting section 130 and the second fixing base 300. The first fixing base 200 and the second fixing base 300 together limit the armrest body 100, and the first support section 120 may be connected to the first fixing base 200 in a socket, a latch, or a screw connection manner, so as to fix the armrest body 100. The second supporting section 130 can also be matched with the second fixing base 300 through a sleeving manner, a supporting manner, and the like, specifically, the second fixing base 300 cannot limit the state of the upward and downward movement of the second supporting section 130, and the more stable the connection state of the second supporting section 130 and the second fixing base 300 is, the smaller the variation range of the signal obtained by the state sensor at the second supporting section 130 is. The first fixing seat 200 and the second fixing seat 300 may be separate or integrated structures.
Due to the user's habit or posture of the bed, the position where the user holds and pulls the armrest body 100 and the direction of the applied force vary. The user may be able to hold and pull the first support section 120, the connecting section 110, and even the second support section 130 in different directions. In the present invention, the first fixing base 200 fixes the first supporting section 120, and the second supporting section 130 can move up and down to match with the second fixing base 300. Regardless of the position and direction of the user's grip and pull, the pull handle body 100 rotates (to a small degree) about the pivot 210, and the state sensor can acquire the feedback signal of the rotation, so that the processor can determine the user's usage state. The state sensor can be selected from the cantilever beam type mechanical sensor 400, the Hall sensor 500, a microswitch, a pressure sensor or a pressure sensor, etc. Taking the second support section 130 having the upward movement state as an example, if a user holds and pulls the first support section 120, the armrest body 100 has a rotation state about the fulcrum 210, and the second support section 130 has the upward movement state, and the state of the second support section 130 generates a signal change on the state sensor. The data of the state sensor is transmitted to the processor, and the processor can judge the state of the user according to the data of the state sensor, so that the state of the user can be sent to the guardian. In this embodiment, the processor can determine the state of the user by providing a pressure sensor or the like on the armrest body 100 to obtain the state of the user using the armrest body 100, regardless of the position of the armrest body 100. Taking the example that the user enters the bed body through the armrest, the user holds the connecting section 110 of the armrest main body 100 first, at this time, the second supporting section 130 descends, and the state sensor obtains a downward movement state signal of the second supporting section 130; when a user enters the bed body and begins to lie down, the user holds and pulls the first supporting section 120, at the moment, the second supporting section 130 rises, and the state sensor obtains a motion state signal of the second supporting section 130 upwards; the processor can thus determine the above-mentioned state process of the user by means of the sensor signals transmitted by the state sensors. It should be noted that, after the processor determines the state process of the user, the processor may notify the guardian of the user, or when the bed body has the intelligent control mechanism, the processor directly sends an instruction to the state change of the bed body after determining the state process of the user.
It should be noted that the status sensor is not limited to only obtaining the ascending or descending status of the second support section 130 as a whole. For example, in one embodiment, the pressure data is used to reflect the rising or falling state, the state sensor is a pressure sensor, and the pressure sensor can obtain the pressure at different positions on the force-bearing surface, so that the user state can be better monitored according to the data of the pressure sensor. In a using process, when a user wants to enter the bed, the armrest body 100 is pulled outwards, so that the armrest body 100 is in an outwards turned state. Particularly, the inner side of the second support section 130 is in an ascending state (pressure data descending), and the outer side of the second support section 130 is in a descending state (pressure data ascending), and the process that the user enters the bed body can be deduced through the data. When the user leaves the bed, the data change process is analogized. In this embodiment, since the state of the user entering and leaving can be determined, it is advantageous for the guardian to grasp the user.
In one embodiment, the fulcrum 210 is located at the bottom of the first fixing base 200.
Since the fulcrum 210 is a fulcrum of the armrest body 100, the fulcrum 210 is disposed lower, so that no matter which angle the user holds and pulls the armrest body 100, there is a larger moment arm, and thus the rotation of the armrest body 100 is larger, which facilitates the state sensor to monitor the upward and downward movement states of the second support section 130. The state sensor can be selected from the cantilever beam type mechanical sensor 400, the Hall sensor 500, a microswitch, a pressure sensor or a pressure sensor, etc.
In one embodiment, the condition sensor is an cantilever beam mechanical sensor 400;
the cantilever beam type mechanical sensor 400 includes a body end and a testing end separately provided on the second support section 130 and the second fixing base 300.
In this embodiment, the main body end of the cantilever-beam-type mechanical sensor 400 is disposed on the second fixing base 300, and the testing end is disposed on the second supporting section 130, so that the testing end can feed back the state of the up-and-down movement of the second supporting section 130 to the main body end. The arm beam type mechanical sensor 400 can better sense the upward or downward state of the second support section 130 through the obtained mechanical signal. The cantilever-type mechanical sensor 400 can obtain a sensitive feedback even when a force acting on the armrest body 100 is small.
Referring to fig. 2, in one embodiment, the status sensor is a hall sensor 500.
The hall sensor 500 using the hall effect can also realize sensing of displacement change, and is an electrical effect, and has the advantages of reliability, simplicity, and easy signal acquisition. Specifically, the hall sensor 500 may be mounted at a free end of the second support section 130, and a component forming an induction with the hall sensor 500 is disposed below the second support section 130 (e.g., mounted on the second fixing base 300); the hall sensor 500 can also be installed on the second fixing base 300, and at this time, a component forming an induction with the hall sensor 500 is installed on the second supporting section 130, it should be noted that if the second supporting section 130 is a magnetizable material, it can directly form an induction with the hall sensor 500.
In one embodiment, the status sensor includes a first pressure sensor and a second pressure sensor, the second fixing base 300 supports the second supporting section 130, and the first pressure sensor and the second pressure sensor are disposed between the second fixing base 300 and the second supporting section 130 and arranged in a thickness direction of the armrest body 100.
In this document, the three-dimensional directions of the armrest body 100 are a length direction (a connecting direction of the first support section 120 and the second support section 130), a height direction (a length direction of the second support section 130 or the first support section 120), and a thickness direction. In this embodiment, the user status can be better monitored according to the pressure data obtained by the first pressure sensor and the second pressure sensor. In a using process, when a user wants to enter the bed, the armrest body 100 is pulled outwards, so that the armrest body 100 is in an outwards turned state. Specifically, the inner side of the second support section 130 is in an ascending state (the pressure data obtained by the first pressure sensor is decreased), and the outer side of the second support section 130 is in a descending state (the pressure data obtained by the second pressure sensor is increased), and the process that the user enters the bed body can be inferred through the data. When the user leaves the bed, the data change process is analogized. Of course, the first pressure sensor and the second pressure sensor are also designed to be redundant to each other, so that the probability of complete failure of the sensing handrail function is reduced. In this embodiment, since the state of the user entering and leaving can be determined, it is advantageous for the guardian to grasp the user.
In one embodiment, the armrest body 100 is fixed to a side surface of the first fixing base 200, and an upper end of the armrest body 100 is inclined toward the first fixing base 200.
In this embodiment, handrail main part 100 is made by panel cutting, and the mode of panel cutting has ensured handrail main part 100's intensity, makes its ability that resists the side direction and push promote, just also ensures that the user falls the probability and reduces. Specifically, in the process, the raw material plate is cut, bent, and shaped, and finally subjected to a shape treatment, thereby obtaining the handrail main body 100. And the upper end of the armrest body 100 is inclined toward the first fixing seat 20 for the user to grasp, and at the same time, to form a surrounding protection feeling for the user. In other embodiments, the armrest body 100 may also be a separate structure, specifically, formed by connecting multiple hollow or solid sections.
In one embodiment, the first fixing seat 200 and the second fixing seat 300 are formed by processing a section bar having a reinforcing bend extending along the length direction on the outer wall.
The profile may be obtained by extrusion, the reinforcing folds of which are formed directly during the extrusion. The strength of the first fixing base 200 and the second fixing base 300 is improved by reinforcing the bending, so that the first fixing base and the second fixing base can be well used as a structural foundation of the armrest main body 100 to better deal with the holding and pulling or lateral pressure of a user.
In one embodiment, the first fixing seat 200 and the second fixing seat 300 are both fixed to a bed.
So that the overall structure of the bed body and the handrail is more concise.
In one embodiment, further comprises a base; the first fixing seat 200 and the second fixing seat 300 are fixed to the base.
In this embodiment, the sensing handrail is not fixed on the bed body, but has a supporting base. For some beds that are inconvenient to use as a fixed foundation, the sensing handrail is convenient.
In one embodiment, the armrest body 100 is U-shaped.
The U-shaped armrest body 100 facilitates the user to hold and pull, and is not easy to injure the user.
The invention also provides an intelligent bed which comprises the sensing handrail.
In the sensing armrest and the intelligent bed of the present invention, the first fixing base 200 fixes the first supporting section 120, and the second supporting section 130 can move up and down and is matched with the second fixing base 300; regardless of the position where the user holds and pulls, the handle body 100 rotates about the fulcrum 210, and the state sensor can acquire a feedback signal of the rotation, so that the processor can determine the use state of the user.
