For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments.

As shown in fig. 1, the electric bed control apparatus according to a preferred embodiment of the present invention includes a base 1 and a control member 2.

In the present embodiment, the electric bed control apparatus is used for controlling an electric bed, and it is understood that it may be used for controlling other devices, such as an electric reclining chair, a wheelchair, and the like.

The base 1 is fixed, and referring to fig. 2, the electric bed has a bed body 91 normally placed on the ground, a mattress 9 provided on the bed body 91, and a frame for driving the deformation of the mattress 9, and the frame may be provided inside the mattress 9 or at the bottom of the mattress 9. The electric bed is also provided with a control system, and the control system drives the mattress 9 to deform by controlling the deformation of the bed frame. The base 1 can be fixedly connected with a bed body 91 of the electric bed, a mattress 9 or a bed frame.

The control member 2 is used for being held by a hand of a person, outputting a corresponding signal to the control system according to the action of the hand, and the control system sending a corresponding control instruction according to the received signal, so as to control the electric bed to execute a corresponding action, such as controlling the deformation of the mattress, playing music, controlling the vibration of the mattress, and the like.

As shown in fig. 3 and 4, the control member 2 includes a housing 20 swingably connected to the base 1, and a first detecting element 21 connected to the housing 20, the first detecting element 21 being configured to detect a swing direction of the housing 20, and when the housing 20 swings with respect to the base 1, the first detecting element 21 is caused to output a detection signal, and the swing direction of the housing 20 can be determined by the detection signal. And the control system calculates to obtain a corresponding control instruction according to the received detection signal so as to control the electric bed to execute corresponding actions.

It will be appreciated that the first sensing element 21 may be adapted to sense a single direction of movement of the housing 20, the first sensing element 21 being triggered only when the housing 20 is moved to one side, causing the first sensing element 21 to output a signal; when it is necessary to detect the movement of the housing 20 in a plurality of directions, it is only necessary to provide a plurality of first detecting elements 21 in different directions, and each first detecting element 21 detects a different swing direction. The first detecting element 21 may be a detecting element capable of detecting movements of the housing 20 in a plurality of directions, and in this case, movements of the housing 20 in a plurality of directions can be detected by at least one first detecting element 21. The first detecting element 21 capable of detecting the movement of the housing 20 in a plurality of directions may be, for example, a three-axis acceleration sensor, an inertial sensor, a gyroscope, or the like, and is capable of determining the swinging direction of the housing 20 based on a movement parameter (for example, a parameter such as acceleration or angular velocity) of the housing 20 to obtain which side the housing 20 is tilted by swinging.

The shell 20 connected with the base 1 in a swinging mode is arranged, so that people only need to hold the shell 20 and then drive the shell 20 to move towards a certain direction to control the electric bed, and the electric bed is more convenient to use. Since the position of the electric bed control apparatus is substantially fixed, a person can quickly hold the housing 20 even in the dark without spending an excessive amount of time searching. Meanwhile, the electric bed control device is controlled through the movement of hands, and a corresponding control button does not need to be found, so that the use convenience is further facilitated.

In some embodiments, at least a portion of the material of the housing 20 is made of an elastic material, which can be elastically deformed after being applied with a force and can be restored to its original shape when the external force is lost, and the elastic material can be, for example, plastic, rubber, silicone, etc. As shown in fig. 5, the portion of the elastic material is preferably ring-shaped, that is, the housing 20 includes an elastic ring 20a, so that the portion of the housing 20 located above the elastic ring 20a can swing with respect to the lower portion by elastic deformation of the elastic material.

In some embodiments, the housing 20 is attached to the base 1 and projects above the mattress to facilitate gripping by a human hand, and its outer surface may be shaped to accommodate gripping by a human hand. In the embodiment shown in fig. 4, the base 1 comprises a fixing member 11 for fixing with the electric bed and a connecting column 10 connected to the fixing member 11, the connecting column 10 is disposed in an upward tilted manner, preferably vertically, and the housing 20 is in an elongated shape and is connected to the connecting column 10. It will be appreciated that the housing 20 is upwardly protruded to be easily grasped by a human hand but easily collided with a human body, and the housing 20 is provided in a form of having an elastic ring 20a or being entirely made of an elastic material to allow the housing 20 to be inclined and evaded when colliding with a human body so as not to damage the human body.

In some embodiments, referring to FIG. 4, the housing 20 is made entirely of an elastic material that allows for greater deformation movement and further reduces the pain associated with an impact.

It is understood that the housing 20 is not limited to be disposed, and may be disposed in an inclined manner or horizontally outward, in addition to being disposed vertically. The shape of the outer shell 20 is not limited, and may be curved, for example, instead of being straight, as shown in fig. 6 and 7, the outer shell 20 is curved, and the middle part thereof protrudes outward away from the mattress 9 (third direction C), so that the upper end thereof is close to the upper part of the mattress 9, which is more convenient for a human hand to hold.

It is understood that, besides the elastic material is provided to enable the housing 20 to swing relative to the base 1, other structures in the prior art can be adopted to realize the swinging connection between the housing 20 and the base 1, such as a rotating shaft connection, a spherical pair connection, etc., and reference can also be made to the structure of the joystick.

In a preferred embodiment, the first detection element 21 is a piezoelectric film sensor, which is attached to the housing 20 and can generate an induced signal in accordance with the deformation of the housing 20. As shown in fig. 4, in the embodiment shown in fig. 4, the housing 20 has a square tubular portion, that is, the housing 20 has an inner cavity 200 with a rectangular cross section, and the piezoelectric film sensor can be attached to the inner wall or the outer wall of the housing 20, preferably the inner wall, so that the housing 20 can protect the piezoelectric film sensor. When the shell 20 is inclined to one side and deformed, the inner wall and the outer wall of the shell are stretched or compressed, the piezoelectric film sensor can generate corresponding induction signals according to the deformation, and after the control system receives the corresponding induction signals, the swinging direction of the shell 20 can be analyzed, namely, the shell 20 is known to be inclined to the side.

Preferably, the piezoelectric film sensor is attached to the portion of the housing 20 made of elastic material, in whole or in part, to facilitate obtaining a larger deformation.

In some embodiments, the electric bed control apparatus includes at least two orthogonally disposed first detecting elements 21 to detect at least two orthogonal swing directions of the housing 20. Preferably, the housing 20 is capable of swinging in three directions to generate different control signals. Specifically, the three directions are a first direction a, a second direction B and a third direction C, wherein the directions of the first direction a and the second direction B are opposite, and the third direction C is perpendicular to both the first direction a and the second direction B and points to the outside of the human body. For the electric bed, the first direction a and the second direction B are parallel to the length direction of the electric bed and point to the bed tail and the bed head, respectively, and the third direction C is parallel to the width direction of the electric bed and points to the outside of the electric bed.

As shown in fig. 4 and 8, the first detecting elements 21 are disposed on at least two adjacent inner walls of the housing 20, and as the housing 20 is tilted forward in the first direction a, the first detecting elements 21 disposed on the first inner wall 202 are stretched and deformed in the first direction a, so as to generate an output signal, and the control system generates a control signal according to the output signal, for example, a signal for controlling the lifting of the mattress; when the housing 20 is tilted back in the second direction B, the first detecting element 21 on the first inner wall 202 is compressively deformed in the first direction a, thereby generating a control signal for controlling the leveling of the mattress, for example; when the housing 20 is tilted outward in the third direction C, the first sensing element 21 located on the second inner wall 203 is deformed, thereby generating a control signal for switching, for example, a manual/automatic control mode of the electric bed. Obviously, it is also possible to provide the first detecting element 21 on the third inner wall 204, and the inclined deformation of the housing 20 to the second direction B is detected by the first detecting element 21 on the third inner wall 204.

The first detecting element 21 may be a piezoelectric film sensor, and may be other sensors, such as a micro switch, besides the sensor that generates a sensing signal by detecting the deformation of the housing 20. As shown in fig. 9, fig. 9 shows an embodiment in which the first detection element 21 is a microswitch. The base 1 is provided with a connecting column 10 extending upwards, the housing 20 is sleeved on the connecting column 10 and is fixedly connected with the connecting column 10, and for example, the fixing can be realized through gluing or bolt connection and other modes. The connecting column 10 is adapted to the shape of the cavity 200 and is also substantially rectangular in cross-section. The upper end of the connecting column 10 is provided with a shrinking part 101 with reduced section size, the outer side surface of the shrinking part 101 is provided with a micro switch, when the shell 20 deforms towards different directions, the shell 20 respectively presses down the micro switches on different outer side surfaces, the micro switches are triggered to output signals to a control system, and the swing direction of the shell 20 can be known according to the micro switches outputting the signals. The control system controls the electric bed to execute different actions according to signals of different micro switches. In this embodiment, the corresponding microswitch can only be triggered when the housing 20 is swung to a particular tilted position. It will be apparent that locating the micro-switch on the inner wall of the housing 20 can serve the same purpose.

It will be appreciated that the cross-sectional shapes of the housing 20 and the connecting column 10 are not limited to rectangular, but may be circular, for example, and that adjacent first detecting elements 21 are only required to be arranged orthogonally, and when the housing 20 is deformed toward the first, second and third directions, the corresponding first detecting elements 21 are triggered.

In order to enable the electric bed control apparatus to output more diversified control commands, the housing 20 is configured to be slidably coupled to the base 1. Specifically, as shown in fig. 10, the housing 20 is sleeved on the connection post 10, and is slidably coupled with the connection post 10. Like this, shell 20 can slide from top to bottom along spliced pole 10, and shell 20 has two extreme positions from top to bottom, is the primary importance respectively and is located the second place of primary importance top, and spliced pole 10 is provided with the spacing groove 100 that extends along the slip direction, and shell 20 then is provided with the spacing portion 203 of protrusion to spacing groove 100 in, realizes spacing to the primary importance and the second place of shell 20 through the cooperation of spacing portion 203 with spacing groove 100.

The electric bed control device also comprises a second detection element 3 for detecting the height position of the shell 20, the second detection element 3 is used for detecting whether the shell 20 is positioned at the first position or the second position and sending corresponding signals to the control system, the control system calculates corresponding control signals according to the signals of the first detection element 21 and the second detection element 3, thus, three control instructions can be obtained by inclining the shell 2 towards three different directions when the shell is positioned at the first position, other three control instructions can be obtained by inclining the shell 2 towards three different directions when the shell is positioned at the second position, and the control capability of the electric bed control device is greatly enriched.

The second detection element 3 may be, for example, a distance sensor, a capacitance sensor, a photoelectric sensor, a microswitch, or the like. As shown in fig. 10, in the embodiment shown in fig. 10, the second detecting device 3 is a micro switch, and a micro switch is disposed on both the upper and lower surfaces of the limiting portion 203, when the housing 2 moves to the first position, the lower micro switch is triggered, and when the housing 2 moves to the second position, the upper micro switch is triggered, and the control system can determine the position of the housing 2 by determining which micro switch sent the received signal. Obviously, two microswitches may be disposed on the upper wall surface 1000 and the lower wall surface 1001 of the limiting groove 100, respectively.

In some embodiments, the base 1 is made of a material with better rigidity and strength to play a role in assisting in getting up, and the material of the base 1 may be, for example, a metal material, a polymer material, or a composite material, preferably, an aluminum alloy, stainless steel, hard plastic, or the like. The base 1 is not easy to deform and break when external force is applied. Thus, when the user needs to get up, the user can directly grasp the corresponding part of the shell 2 and the connecting column 10, and pull the connecting column 10 to get up. For weak or handicapped people, the connecting column 10 is arranged to facilitate the force application of the weak or handicapped people, so that the weak or handicapped people can get up more easily and the dependence on other people is reduced.

As a preferred embodiment, the current deforming action of the electric bed can be stopped immediately when the housing 20 is tapped continuously in any case, so that a sudden stop can be achieved in an emergency. When the housing 20 is tapped, the first detecting element 21 (or other detecting elements) can continuously generate a trigger signal, and the control system can determine whether the housing 20 is tapped continuously according to parameters such as the intensity and/or the interval time of the trigger signal, and further output a control signal for controlling the electric bed to stop the current operation.

In a preferred embodiment, the third detecting element 5 is a temperature sensor disposed in the inner cavity 200 and contacting the concave shell 206, and is attached to the concave shell 206 when a finger is inserted into the concave hole 201, so that whether the finger is inserted can be determined by detecting a temperature change of the concave shell 206. It is understood that the concave shell 206 is preferably made of a material with good heat conduction effect, such as aluminum alloy, copper, etc. In another preferred embodiment, the third detecting element 5 is a photoelectric switch, and when a finger is inserted into the recessed hole 201, the photoelectric switch is blocked to generate a sensing signal.

The recessed hole 201 provided for inserting the finger can realize various functions, for example, can be used for preventing the erroneous operation, and since the insertion of the finger into the recessed hole 201 is a conscious behavior, the finger is inserted into the recessed hole 201 only when it is desired to control the electric bed by swinging the housing 20, and when the finger is not inserted into the recessed hole 201, even if the housing 20 is swung, the control system does not output the control instruction, thereby realizing the function of preventing the erroneous operation. Preferably, the recessed hole 201 is provided at a position where fingers are not easily touched when holding the housing 20, to ensure that a person intentionally inserts the fingers for control, further preventing an erroneous operation. For another example, the recessed hole 201 may also increase the control function of the electric bed control apparatus, and in both cases of inserting a finger into the recessed hole 201 and not inserting a finger, even if the housing 20 is swung in the same manner, different control signals may be generated, thereby further enriching the types of control signals that the electric bed control apparatus can generate.

For example, in a dark environment, the luminance of the light-emitting device 6 can be appropriately adjusted low to prevent glare. The ambient light sensor is preferably installed on the base 1 and is installed downward, and since the brightness of light rays from above is easily disturbed by the light rays from the light emitting device 6, the ambient light sensor is installed below and downward, and thus ambient light rays can be detected more accurately.

As a preferred embodiment, the electric bed control apparatus further includes a vibration device 8 disposed in the housing 20, and a vibration feedback can be given to a human hand (e.g., palm or finger) by the vibration of the vibration device 8.

For another example, when the housing 20 is pulled to trigger the second detecting element 3 above, the control system controls the vibrating device 8 to vibrate to give an indication that the housing is pulled to the right position. For another example, when the third detecting element 5 detects that the finger is inserted into the recessed hole 201, the control system controls the vibrating device 8 to vibrate to make a prompt for confirming the insertion of the finger.
