Furthermore, the pose transformation device provided with the induction device can be used in combination with other intelligent equipment to realize intelligent home life; the utility model provides an in the example, can arrange little night-light use in collocation, install the position appearance transform device to the footpost side, can avoid the user to sleep unconsciously the removal in bed and trigger human sensor and turn on little night-light, the user is comfortable and easy to sleep night evening, need not to grope the bright lamp switch, the foot is once fallen to the ground, little night-light just lights automatically, the night walk at home is light and loose, and simultaneously, can also set up little night-light people and come to open promptly, walk the back and delay and close, let the user fully experience scientific and technological glamour. All the following embodiments of the present invention will be specifically described by taking the external device as an example.

Referring to fig. 1 to 30, a pose transformation apparatus 1 according to the present disclosure is specifically explained based on fig. 1 to 30. Specifically, as shown in fig. 1, fig. 1 is a schematic structural view of a pose transformation apparatus 1 shown according to an exemplary embodiment. As can be seen from fig. 1, the posture changing apparatus 1 includes: a base 11, at least one first angle transformer 12 and at least one second angle transformer 13; the second angle transformer 13 is rotatably connected with the base 11 through the first angle transformer 12, so that the second angle transformer 13 can transform angles in at least two degrees of freedom relative to the base 11, and the rotating shafts of the two degrees of freedom are not coincident;

the second angle transformer 13 is rotatably connected to the base 11 via the first angle transformer 12, which means that the first angle transformer 12 is rotatably connected to the base 11, while the second angle transformer 13 is rotatably connected to the first angle transformer 12. The second angle transformer 13 is capable of transforming angles in at least two degrees of freedom with respect to the base 11, it being understood that the first angle transformer 12 is rotatably connected to the base 11 such that the first angle transformer 12 is rotatable in a first degree of freedom with respect to the base 11, the second angle transformer 13 being rotatable in the first degree of freedom with respect to the base 11 due to the connection of the second angle transformer 13 to the first angle transformer 12; the second angle transformer 13 is rotatably connected to the first angle transformer 12, such that the second angle transformer 13 is rotatable in a second degree of freedom with respect to the first angle transformer 12, thereby enabling the second angle transformer 13 to change angles in at least two degrees of freedom with respect to the base 11.

As shown in fig. 2, the second angle transformer 13 is configured to support a sensing device 2, and is adapted to drive the sensing device 2 to perform pose transformation under an external operation, and support the sensing device 2 to maintain a current pose when the external operation is removed. The second angle transformer 13 supports a sensing device 2 specifically includes that the second angle transformer 13 is detachably or non-detachably fixedly connected with the sensing device 2, and is installed and fixed in a magnetic attraction manner, an adhesion manner, a buckling manner or a thread manner, for example, so that the sensing device 2 moves along with the second angle transformer 13. When the external operation is removed, the pose transformation device 1 is prevented from continuing to move along with inertia due to the fact that large damping exists among moving components of the pose transformation device 1, the current pose of the pose transformation device 1 is maintained, and correspondingly, the pose transformation device 1 drives the induction device 2 to stop moving and supports the induction device 2 to keep the current pose.

In practical use, as shown in fig. 5, the base 11 is fixedly mounted to a mounting reference surface 4 to support the attitude changing device 1; the sensing device 2 includes a sensor capable of sensing body movement, such as a pyroelectric body sensor or other sensor. The second angle transformer 13 can transform angles in at least two degrees of freedom relative to the base 11, when the pose transformation device 1 transforms the pose under external operation, the sensing device 2 correspondingly transforms the pose along with the second angle transformer 13, so that the sensing area 3 is changed; when the external manipulation is removed, the second angle transformer 13 supports the sensing device 2 to maintain the current pose, so that the sensing region 3 is fixed. The induction device 2 is matched with the pose transformation device 1 for use, and can change angles on at least two degrees of freedom relative to the base 11 along with the second angle transformer 13, so that the angle adjustable range is enlarged, and the practicability of the human body sensor is improved. To adapt to the actual installation situation, the user can control the sensing area 3 of the sensing device 2 in a preferred area by adjusting the second angle transformer 13; in the above exemplary embodiment, the orientation of the sensing device 2 is adjusted to be opposite to the doorway of the bedroom, the sensing area 3 is partially shielded by the structure of the bed frame, and only the sensing area 3 of the other part is used for sensing, so that the arrangement can avoid that the night light is often triggered by mistake due to the fact that the sensing device 2 senses the movement of the human body in the living room outside the bedroom.

In some embodiments, as shown in fig. 3-4, the first angle transformer 12 is rotatably connected to the base 11 by a first rotating shaft 14; the second angle transformer 13 is rotatably connected to the first angle transformer 12 via a second rotational axis 15, such that the second angle transformer 13 is angularly displaceable in a first degree of freedom with respect to the base 11 via the first rotational axis 14 and in a second degree of freedom via the second rotational axis 15.

Specifically, the first angle transformer 12 transforms an angle in a first degree of freedom relative to the base 11 through the first rotating shaft 14, and when the second rotating shaft 15 does not rotate, the second angle transformer 13 is stationary relative to the first angle transformer 12, so that the second angle transformer 13 transforms an angle in the first degree of freedom relative to the base 11 following the first angle transformer 12; the second angle transformer 13 transforms an angle in a second degree of freedom with respect to the first angle transformer 12 via the second rotation axis 15, the first angle transformer 12 being stationary with respect to the base 11 when the first rotation axis 14 is not rotated, such that the second angle transformer 13 transforms an angle in a second degree of freedom with respect to the base 11; alternatively, the first rotation shaft 14 and the second rotation shaft 15 rotate simultaneously, so that the second angle transformer 13 transforms the attitude in the first degree of freedom and the second degree of freedom simultaneously with respect to the base 11. It should be noted that the first rotating shaft 14 and the second rotating shaft 15 can be understood as specific rotating shaft components, and can also be understood as an axis of relative rotation between the components.

Wherein the first rotation shaft 14 is located at a central position of the base 11 while being disposed at a central position of the first angle transformer 12 such that the first angle transformer 12 can rotate about a central axis thereof to facilitate a user to manipulate to rotate the first angle transformer 12; simultaneously, in an exemplary embodiment, base 11 with first angle transformer 12 is cylindrically, first rotation axis 14 with columniform axis coincidence makes first angle transformer 12 is relative when base 11 is rotatory, and first angle transformer 12's outline does not change, the condition that first angle transformer 12 collided the surrounding environment thing when rotating can not appear, and the base 11 of being convenient for adjusts the position appearance in narrow and small installation environment.

In some embodiments, as shown in fig. 5, the rotation angle of the first rotating shaft 14 is set to 0 ° to 360 °, and the rotation angle of the second rotating shaft 15 includes 0 ° to 90 °.

Specifically, the first angle transformer 12 is connected to the base 11 by riveting, the first angle transformer 12 can rotate around the first rotation axis 14360 °, and the first angle transformer 12 can circumferentially continuously and circularly rotate or circumferentially reciprocally rotate around the first rotation axis 14, wherein the circumferential continuous and circular rotation can improve the convenience of use. The rotation angle of the second rotation axis 15 includes 0 ° to 90 °, and it can be understood that the deployment angle of the second angle transformer 13 with respect to the first angle transformer 12 includes at least 0 ° to 90 °, and the 360 ° adjustment range of the first angle transformer 12 is matched, so that the angle adjustable range of the pose transformation apparatus 1 is further expanded.

In some embodiments, as shown in fig. 5 to 6, a spatial angle is formed between the first rotation axis and the second rotation axis, and the spatial angle is set to be 90 °, so that the second angle converter 13 can drive the sensing device 2 to convert the sensing region 3 in at least a hemispherical range.

The spatial angle between the first rotating shaft 14 and the second rotating shaft 15 may be any angle within a range of 0 ° to 360 °, specifically including that, when the spatial angle is 0 ° (not shown in the figure), the first rotating shaft 14 is parallel to the second rotating shaft 15, and the second angle converter 13 is adjustable within an arc range relative to the base 11. When the included spatial angle is not equal to 0 ° or 180 °, the first rotation axis 14 is inclined with respect to the second rotation axis 15, and the second angle transformer 13 is adjustable within a non-complete spherical range with respect to the base 11.

Where the spatial angle is 90 °, it is understood that the first rotation axis 14 is perpendicular to the second rotation axis 15, and, for example, the first rotation axis 14 is in a vertical state, the second rotation axis 15 is in a horizontal state, the first angle transformer 12 is rotatable in a horizontal space around the first rotation axis 14, the second angle transformer 13 is rotatable in a vertical space around the second rotation axis 15, so that the adjustable range of the first angle transformer 12 relative to the base 11 can cover a hemispherical range, and then, in cooperation with the sensing angle (generally greater than 90 °) of the sensing device 2, the adjustment range of the sensing area 3 of the sensing device 2 can cover a range larger than a hemisphere, and the adjustment range can be suitable for most of use scenes of the sensing device 2 and can sufficiently meet the use requirements of users.

In some embodiments, the first rotation axis 14 does not intersect the second rotation axis 15.

Specifically, as shown in fig. 6, when the first rotation shaft 14 intersects the second rotation shaft 15, the second rotation shaft 15 passes through an upper portion of the first rotating body and has an intersection with the second rotation shaft 15, the first angle converter 12 is provided with the first rotation shaft 14, and the base 11 and the first rotation shaft 14 of the first angle converter 12 are riveted by a rivet 114, so that the first angle converter 12 can rotate about the first rotation shaft 14 with respect to the base 11. The second angle converter 13 is provided with a first rotating shaft hole 16 which can be matched with the first rotating shaft 14, the second rotating shaft 15 is inserted into the first rotating shaft hole 16, and the second rotating shaft 15 penetrates through the first angle converter 12, so that the second angle converter 13 is rotatably connected with the first angle converter 12 through the second rotating shaft 15; at the moment, the first rotating shaft 14 and the second rotating shaft 15 are combined to achieve the effect of being similar to a spherical pair, so that the hand feeling of a user for adjusting the angle in two degrees of freedom is better, and the convenience of adjustment is beneficial to a certain extent.

When the first rotating shaft 14 and the second rotating shaft 15 do not intersect with each other, as shown in fig. 5 and 7, the first angle transformer 12 is provided with a second rotating shaft hole 17 at a position deviated from the center, the second rotating shaft 15 is inserted into the second angle transformer 13 and can be fitted into the second rotating shaft hole 17, and the second rotating shaft 15 is inserted into the second rotating shaft hole 17, so that the second angle transformer 13 is rotatably connected with the first angle transformer 12 through the second rotating shaft 15; due to the fact that a certain distance is reserved between the two rotating shafts, the adjustment of the first degree of freedom and the adjustment of the second degree of freedom are not prone to mutual interference, the second degree of freedom is not prone to changing along with the first degree of freedom when the first degree of freedom is adjusted, angles of the two degrees of freedom can be adjusted independently, and the stability of angle adjustment is improved.

In some embodiments, the second rotation axis 15 is located at the edge of the second angle transformer 13.

For example, as shown in fig. 8, the first angle converter 12 is provided with a pivot portion 1201, the pivot portion 1201 is provided with a second rotating shaft hole 17 for the second rotating shaft 15 to pass through, the second rotating shaft 15 is a pivot shaft, the edge of the second angle converter 13 is provided with a rotating shaft connecting portion 1301 for connecting the second rotating shaft 15, the rotating shaft connecting portion 1301 is provided with the first rotating shaft hole 16 matched with the shaft diameter of the second rotating shaft 15, and the second rotating shaft 15 passes through the first rotating shaft hole 16 and is fixed to the rotating shaft connecting portion 1301.

An accommodating notch 1302 is formed in the middle of the spindle connection portion 1301, and the pivot portion 1201 can fit into the accommodating notch 1302, so that the second rotating shaft 15 penetrates through the spindle connection portion 1301 and the pivot portion 1201 to realize the pivot connection between the second angle converter 13 and the first angle converter 12. The pivotal motion of the second angle converter is coordinated with the rotational motion of the first angle transformer 12 to expand the adjustable range of the pose transformation apparatus 1. The second rotation shaft 15 is provided at the edge of the second angle transformer 13, which prevents interference when the second angle transformer 13 performs a pivotal motion, and contributes to widening the range of angular adjustment of the second angle transformer 13 with respect to the first angle transformer 12.

in the first state, the first contact surface 1202 of the first angle transformer 12 and the second contact surface 1303 of the second angle transformer 13 are at least partially contacted;

in the second state, the first attachment surface 1202 and the second attachment surface 1303 form a predetermined angle therebetween.

The first attaching surface 1202 and the second attaching surface 1303 are attached to each other at least partially, including the first attaching surface 1202 and the second attaching surface 1303 are attached to each other completely or partially; the first state can be understood as a state in which the included angle between the first angle transformer 12 and the second angle transformer 13 is 0 °, and when in the first state, the first abutting surface 1202 is a surface of the first angle transformer 12 facing the second angle transformer 13, i.e., an upper surface of the first angle transformer 12 in fig. 11, and the second abutting surface 1303 is a surface of the second angle transformer 13 facing the first angle transformer 12, i.e., a lower surface of the second angle transformer 13 in fig. 11. As shown in fig. 11 to 12, the pivot portion 1201 of the first angle transformer 12 protrudes from the first abutting surface 1202, and the second rotation axis 15 passes through the pivot portion 1201, so that the second angle transformer 13 can perform a pivotal motion around the second rotation axis 15 relative to the first angle transformer 12, and in the second state, the first angle transformer 12 is unfolded relative to the second angle transformer 13 to reach the designated angle; illustratively, the height of the second rotation axis 15 is higher than that of the first abutting surface 1202, so that the first abutting surface 1202 can abut against the second abutting surface 1303, and meanwhile, the interference can be prevented when the second angle converter 13 rotates around the second rotation axis 15. As shown in fig. 7 and 11, the first angle transformer 12 is provided with an avoiding portion 1210, the avoiding portion 1210 is located on both sides of the pivoting portion 1201 and is recessed in the first abutting surface 1202, and when the second angle transformer 13 performs a pivoting motion about the second rotation axis 15, the avoiding portion 1210 can avoid the second angle transformer 13 so that the second angle transformer 13 does not interfere with the edge of the first angle transformer 12. When the first angle transformer 12 is attached to the second angle transformer 13, the overall thickness of the pose transformation device 1 is small, so that the pose transformation device can be conveniently installed in a narrow space, and the existing feeling of the pose transformation device 1 can be weakened; meanwhile, as shown in fig. 13, the pose transformation device 1 and the induction device 2 are both cylindrical, so that the pose transformation device 1 and the induction device 2 are integrated visually, and the radius of the pose transformation device 1 is smaller than that of the induction device 2, so that the pose transformation device 1 is hidden between the induction device 2 and the installation reference surface 4 when the pose transformation device 1 is in the first state, the existence sense of the base 11 is weakened, and the integral attractiveness is improved.

In some embodiments, as shown in fig. 14, the base 11 further includes a fourth abutting surface 1101, and the fourth abutting surface 1101 is disposed opposite to the first abutting surface 1202;

the fourth attachment surface 1101 is configured to be attachable to an installation reference surface 4, and is fixedly connected to the installation reference surface 4.

Specifically, the fourth abutting surface 1101 is a surface of the base 11 away from the first angle transformer 12, and it can be understood that the fourth abutting surface 1101 is fixedly connected to the installation reference surface 4, that is, the fourth abutting surface 1101 can be bonded to the installation reference surface 4, bolted to the installation reference surface, connected to a suction cup, connected to a magnetic suction device, or connected to another connection manner (not shown in the drawings) that can be implemented by a person skilled in the art, so that the base 11 is fixedly connected to the installation reference surface 4 to support the posture changing device 1 to change the posture. In practical use, the fourth bonding surface 1101 may be applied with an adhesive 1315, so that the base 11 can be bonded to a wall surface, a desktop, a cabinet surface, and the like, thereby fixing the base 11; or the fourth binding surface 1101 is provided with a threaded hole and detachably connected with the mounting reference surface 4 through a bolt; or the fourth abutting surface 1101 is provided with at least one suction cup, so that the base 11 can be adsorbed on the smooth surface of an object such as a ceramic tile, glass and the like, the pose transformation device 1 and the installation reference surface 4 can be conveniently assembled and disassembled, and no trace is left on the installation reference surface 4; or the fourth bonding surface 1101 is provided with a magnet capable of being adsorbed on the surface of an iron object, so that the base 11 and the installation reference surface 4 can be quickly disassembled and assembled; according to different use requirements of users, different connection modes can be selected, and the application range is wide.

It can be understood that when the second angle transformer 13 rotates relative to the first angle transformer 12, at least one portion of the second angle transformer 13 contacts the first angle transformer 12, so that the first angle transformer 12 cannot rotate any more, and the included angle between the second angle transformer 13 and the first angle transformer 12 is at a maximum.

The technical feature is designed to enable the included angle between the second angle converter 13 and the first angle converter 12 to be rapidly adjusted to a predetermined angle; for example, when the maximum included angle is set to 90 °, and the user adjusts the included angle between the second angle converter 13 and the first angle converter 12 to 90 ° so that the user can operate the angle blindly, the included angle between the second angle converter 13 and the first angle converter 12 can be adjusted to 90 ° quickly, because the 90 ° state is a common state in practical use, for example, the base 11 is fixed on the wall surface on the upper portion of the door frame, the sensing direction of the sensing device 2 needs to be set vertically downward, so that the sensing device 2 is triggered when a human body enters the door frame, or when the base 11 is placed on a desktop, the sensing direction of the sensing device 2 needs to be set horizontally, or when the base 11 is fixed on a vertical wall surface, the sensing direction of the sensing device 2 needs to be set horizontally, the above-mentioned usage scenarios all need to adjust the included angle between the second angle converter 13 and the first angle converter 12 to 90 °, the user can adjust to 90 fast, improves the convenience of operation.

when the included angle between the second angle transformer 13 and the first angle transformer 12 reaches the maximum, the first abutting portion 1209 abuts against the second abutting portion 1304. In an exemplary embodiment, the outer surface of the second abutting portion 1304 and the side surface of the second angle transformer 13 are a complete surface to maintain the integrity of the shape of the side surface of the second angle transformer 13, and when the second angle transformer 13 is folded with the first angle transformer 12, as shown in fig. 15, the first abutting portion 1209 and the second abutting portion 1304 are included in the outer contour of the first angle transformer 12 and the second angle transformer 12, so that the appearance integrity of the pose transformer is good.

The second angle converter 13 is disposed on a third attaching surface 1305 opposite to the second attaching surface 1303, and it can be understood that the second attaching surface 1303 and the third attaching surface 1305 are respectively located on two opposite sides of the second angle converter 13; the second angle transformer 13 is connected to the sensing device 2 via the third attachment surface 1305, it being understood that the third attachment surface 1305 is detachably or non-detachably fixed to the sensing device 2, for example, by magnetic attraction, adhesion, clamping, screwing or other connection means that can be implemented by a person skilled in the art. The angle between the second angle transformer 13 and the first angle transformer 12 is 90 °, and it can be understood that the angle between the first contact surface 1202 and the second contact surface 1303 reaches 90 ° when the second angle transformer 13 rotates around the second rotation axis 15. The third attaching surface 1305 is tangent to the side surface of the first angle transformer 12, and it is understood that the first angle transformer 12 is cylindrical and has a circular arc surface, and the plane where the third attaching surface 1305 is located can be tangent to the circular arc surface.

Specifically, in an exemplary embodiment, as shown in fig. 17, the sensing device 2 is mounted to the second angle transformer 13, the third attaching surface 1305 is attached to the bottom of the sensing device 2, when the included angle between the second angle transformer 13 and the first angle transformer 12 is 90 °, since the third attaching surface 1305 is tangent to the side surface of the first angle transformer 12, the bottom of the sensing device 2 is abutted against the side surface of the first angle transformer 12, and the second rotating shaft 15 cannot rotate by a larger angle; in other embodiments, the third attaching surface 1305 may also be attached to other surfaces of the induction device 2 so as to abut against the side surface of the first angle transformer 12. According to the technical scheme, under the condition that the first abutting part and the second abutting part are not used, the included angle between the second angle converter 13 and the first angle converter 12 can be adjusted to 90 degrees quickly, and convenience of angle adjustment is guaranteed.

It should be noted that the distance from the second rotation axis 15 to the third attaching surface 1305 is a first distance, a perpendicular line is drawn between the second rotation axis 15 and the first rotation axis 14, the perpendicular line is perpendicular to both the first rotation axis 14 and the second rotation axis 15, the perpendicular line is extended to the side surface of the first angle transformer 12, and an intersection point is formed between the side surface and the perpendicular line of the second rotation axis 15, the intersection point is a second distance, and the first distance and the second distance are equal, so that when the included angle between the second angle transformer 13 and the first angle transformer 12 is 90 °, the third attaching surface 1305 is tangent to the side surface of the first angle transformer 12.

Based on the pose transformation device 1 provided by the embodiment, the disclosure also provides a human body sensor; referring to fig. 1 to 47, a human body sensor according to the present disclosure is specifically illustrated. Specifically, as shown in fig. 1-2, the human body sensor comprises a pose transformation device 1 and a sensing device 2; the induction device 2 is detachably connected to the pose transformation device 1; the pose transformation device 1 is arranged to transform angles in at least two degrees of freedom and drive the induction device 2 to transform the induction area 3, and the rotating shafts of the two degrees of freedom do not coincide. The two degrees of freedom can be understood as two non-coincident rotational degrees of freedom, and the connection part of the posture changing device 1 and the sensing device 2 can rotate on at least two rotational degrees of freedom relative to the installation reference surface 4, so as to drive the sensing device 2 to rotate on at least two rotational degrees of freedom relative to the installation reference surface 4, so as to change the sensing area 3.

The induction device 2 is matched with the pose transformation device 1 for use, so that the induction device 2 can transform angles on at least two degrees of freedom relative to the installation reference surface 4, the angle adjustable range is enlarged, and the practicability of the human body sensor is improved.

In some embodiments, as shown in fig. 1, the posture changing apparatus 1 includes: a base 11, at least one first angle transformer 12 and at least one second angle transformer 13; the second angle transformer 13 is rotatably connected to the base 11 via the first angle transformer 12, such that the second angle transformer 13 can transform angles in at least two degrees of freedom with respect to the base 11;

The second angle transformer 13 supports an induction device 2, and the second angle transformer 13 is detachably or non-detachably fixedly connected with the induction device 2, so that the induction device 2 moves along with the second angle transformer 13. When the external control is removed, a large damping exists between each moving part of the pose transformation device 1 to prevent the pose transformation device 1 from continuously moving along with inertia and maintaining the current pose, and meanwhile, the sensing device 2 is driven to stop moving and the sensing device 2 is supported to keep the current pose. The specific principles and details are described above and will not be described herein.

The sensing device 2 includes a sensor capable of sensing human body movement, such as a pyroelectric human body sensor or other sensor. The second angle transformer 13 can transform angles in at least two degrees of freedom relative to the base 11, when the pose transformation device 1 transforms the pose under external operation, the sensing device 2 correspondingly transforms the pose along with the second angle transformer 13, so that the sensing area 3 is changed; when the external manipulation is removed, the second angle transformer 13 supports the sensing device 2 to maintain the current pose, so that the sensing region 3 is fixed. In order to adapt to the actual installation situation, the user can control the sensing area 3 of the sensing device 2 in a preferred area by adjusting the second angle transformer 13, and the specific installation embodiment is described above and will not be described herein again.

The specific principle and details of this technical solution can be referred to the related descriptions of the foregoing embodiments, and will not be described herein again.

The first rotating shaft 14 of the present disclosure is located at a central position of the base 11, and is disposed at a central position of the first angle transformer 12, so that the first angle transformer 12 can rotate around its central axis, so as to facilitate a user to manipulate and rotate the first angle transformer 12; simultaneously, in an exemplary embodiment, base 11 with first angle converter 12 is cylindrically, first rotation axis 14 with columniform axis coincidence makes first angle converter 12 is relative when base 11 is rotatory, and the outline of first angle converter 12 does not change, and the condition that first angle converter 12 bumps the surrounding environment thing when rotating can not appear, and the base 11 of being convenient for adjusts the position appearance in narrow and small installation environment, and then is convenient for induction system 2 angle of adjustment in narrow and small installation environment.

Specifically, the first angle transformer 12 is connected to the base 11 by riveting, the first angle transformer 12 can rotate around the first rotation axis 14360 °, and the first angle transformer 12 can circumferentially continuously and circularly rotate or circumferentially reciprocally rotate around the first rotation axis 14, wherein the circumferential continuous and circular rotation can improve the convenience of use. The rotation angle of the second rotation axis 15 is 0 to 90 °, and it can be understood that the deployment angle of the second angle transformer 13 relative to the first angle transformer 12 is at least 0 to 90 °, and the 360 ° adjustment range of the first angle transformer 12 is matched, so that the angle adjustable range of the pose transformation device 1 is further expanded, and the angle adjustable range of the induction device 2 is further expanded.

The spatial angle between the first rotating shaft 14 and the second rotating shaft 15 may be any angle within a range of 0 to 360 degrees, and when the spatial angle is 0 degree (not shown in the figure), the first rotating shaft 14 is parallel to the second rotating shaft 15, and the second angle converter 13 may be adjusted within an arc range with respect to the base 11, and in cooperation with the sensing angle (generally greater than 90 degrees) of the sensing device 2, the adjustable range of the sensing region 3 of the sensing device 2 may cover a non-complete spherical range. When the spatial angle is not equal to 0 ° or 180 °, the first rotating shaft 14 is inclined with respect to the second rotating shaft 15, and the second angle converter 13 is adjustable with respect to the base 11 within a partial spherical range, so as to match the sensing angle of the sensing device 2 itself, such that the adjustable range of the sensing region 3 of the sensing device 2 can cover at least a non-complete spherical range.

In some embodiments, the first rotation axis 14 does not intersect the second rotation axis 15. The specific principle and details of this technical solution can be referred to the related descriptions of the foregoing embodiments, and will not be described herein again.

When first rotation axis 14 with when second rotation axis 15 is crossing, as shown in fig. 6, the user feels of angle regulation better on two degrees of freedom, has certain benefit to the convenience of regulation, simultaneously, first angle converter 12 only needs central point to realize above-mentioned connection function promptly, can shorten first angle converter 12's volume reduces the space that position appearance conversion equipment 1 occupy makes induction system 2 can install in narrow and small installation environment. When the first rotating shaft 14 and the second rotating shaft 15 do not intersect, as shown in fig. 5 and 7, because a certain distance exists between the two rotating shafts, the adjustment of the first degree of freedom and the adjustment of the second degree of freedom do not interfere with each other easily, and the situation that the second degree of freedom changes with each other when the first degree of freedom is adjusted does not occur easily, so that the angles of the two degrees of freedom can be adjusted independently, and the stability of angle adjustment is increased.

In some embodiments, as shown in fig. 8, the second rotation axis 15 is located at the edge of the second angle transformer 13. The specific principle and details of this technical solution can be referred to the related descriptions of the foregoing embodiments, and will not be described herein again.

The second rotating shaft 15 is disposed at the edge of the second angle converter 13, so that interference generated when the second angle converter 13 performs a pivoting motion can be prevented, which is helpful for expanding the angle adjustment range of the second angle converter 13 relative to the first angle converter 12, and further expanding the adjustable range of the sensing device 2.

in the second state, the first attachment surface 1202 and the second attachment surface 1303 form a predetermined angle therebetween. The specific principle and details of this technical solution can be referred to the related descriptions of the foregoing embodiments, and will not be described herein again.

When the first angle transformer 12 is attached to the second angle transformer 13, the overall thickness of the pose transformation device 1 is small, so that the pose transformation device can be conveniently installed in a narrow space, the induction device 2 can be installed in the narrow space, and the overall thickness of the pose transformation device 1 is small, so that the existing feeling of the pose transformation device 1 can be weakened, and the overall aesthetic property of the human body sensor is improved; meanwhile, as shown in fig. 13, the pose transformation device 1 and the induction device 2 are both cylindrical, so that the pose transformation device 1 and the induction device 2 are integrated in a visual sense, and the radius of the pose transformation device 1 is smaller than that of the induction device 2, so that the pose transformation device 1 is hidden between the induction device 2 and the installation reference surface 4 when the pose transformation device 1 is in the first state, the existence sense of the base 11 is weakened, and the integral aesthetic property of the human body sensor is improved.

In some embodiments, as shown in fig. 11 and 12, the second rotation axis 15 is located at an edge of the first angle transformer 12, so that the first abutting surface 1202 and the second abutting surface 1303 completely abut in the first state of the posture changing apparatus 1. The specific principle and details of this technical solution can be referred to the related descriptions of the foregoing embodiments, and will not be described herein again.

In some embodiments, the specified included angle is set to 90 °. Because the 90 ° state is a state that is commonly used in practical use, as shown in fig. 17, for example, when the base 11 is fixed on a wall surface at the upper portion of a door frame, the sensing direction of the sensing device 2 needs to be set vertically downward, so that a human body enters the door frame to trigger the sensing device 2, or when the base 11 is placed on a desktop, the sensing direction of the sensing device 2 needs to be set horizontally, or when the base 11 is fixed on a vertical wall surface, the sensing direction of the sensing device 2 needs to be set horizontally, the above usage scenarios all need to adjust the included angle between the second angle transformer 13 and the first angle transformer 12 to 90 °, and if a user can quickly adjust the included angle to 90 °, the convenience of operation can be improved.

the third contact surface 1305 is tangent to a side of the first angle transformer 12, so that the induction device 2 is in contact with the side of the first angle transformer 12. The specific principle and details of this technical solution can be referred to the related descriptions of the foregoing embodiments, and will not be described herein again.

Specifically, in an exemplary embodiment, as shown in fig. 17, the sensing device 2 is mounted to the second angle transformer 13, the third attaching surface 1305 is attached to the bottom of the sensing device 2, and when the included angle between the second angle transformer 13 and the first angle transformer 12 is 90 °, the bottom of the sensing device 2 is abutted against the side surface of the first angle transformer 12, so that the second rotating shaft 15 cannot rotate by a larger angle; in other embodiments, the third attaching surface 1305 may also be attached to other surfaces of the induction device 2 so as to abut against the side surface of the first angle transformer 12. According to the technical scheme, under the condition that the first abutting part and the second abutting part are not used, the included angle between the second angle converter 13 and the first angle converter 12 can be adjusted to 90 degrees quickly, and convenience of angle adjustment is guaranteed.

In some embodiments, as shown in fig. 21, the second angle transformer 13 further comprises a third abutting surface 1305 disposed opposite to the second abutting surface 1303; the third contact surface 1305 is formed with a weight reduction groove 1308 for reducing the weight of the second angle converter 13. So as to prevent the first rotation axis 14 and the second rotation axis 15 from changing angles under the action of the gravity of the second angle transformer 13, resulting in a change of the sensing area 3 of the sensing device 2; in practical use, since the first rotating shaft 14 and the second rotating shaft 15 are both movable parts and the attitude of the angle transformation device is maintained only by the rotation damping, the attitude of the angle transformation device may change slowly, and the reduction in weight of the second angle transformer 13 can avoid the occurrence of the attitude change to some extent.

In some embodiments, as shown in fig. 1 and 20, when the first angle transformer 12 moves relative to the base 11 in response to an external drive, a first limit force is generated between the base 11 and the first angle transformer 12 to prevent the first angle transformer 12 from moving; the first restraining force is arranged to limit the movement of the first angle transformer 12 when the external drive is removed. Specifically, when the external drive acts on the pose transformation device 1, the first angle transformer 12 rotates relative to the base 11, and a friction force is generated between the first angle transformer 12 and the base 11 during the rotation process to prevent the relative rotation, where the friction force is the first limit force. The first limiting force can make the first angle converter 12 stop immediately after rotating, so that the adjustment by a user is facilitated, the induction device 2 cannot be excessively adjusted in angle due to inertia, and the user can accurately adjust the induction area 3 conveniently.

In some embodiments, as shown in fig. 20, the first angle transformer 12 has at least one fitting region 1206 fitting to the base 11; the first angle transformer 12 is configured to generate the first restraining force at the attachment region 1206 when moving relative to the base 11 in response to an external drive. The upper surface of the base 11 is attached to the lower surface of the second receiving portion 1204 of the first angle transformer 12 to form the attaching region 1206, the rivet 114 has a pre-tightening force, so that the upper surface of the base 11 is attached to the lower surface of the second receiving portion 1204, when the first angle transformer and the base 11 rotate relatively, the attaching region 1206 generates a friction force to hinder the first angle transformer and the base 11 from rotating relatively, when the external drive is removed, the attaching region 1206 generates a friction force to brake the first angle transformer to move relative to the base 11 and maintain the current pose, so as to maintain the current pose of the sensing device 2 and fix the sensing region 3. Furthermore, the rivet 114 rivets the base 11 to the second angle transformer 13, the base 11 is recessed into a circular recessed portion at a central position, a nut extends from the bottom of the rivet 114 in an outward circumferential direction, and an upper surface of the top nut is tightly attached to a lower surface of the recessed portion, so that when the first angle transformer and the base 11 rotate relatively, another friction force is generated between the top nut and the recessed portion, and the first angle transformer 12 is further prevented from rotating relative to the base 11.

at least one light incident surface 2401, which is configured to receive the incidence of the light in the sensing region 3; and

at least one light emitting surface 2402 opposite to the light incident surface 2401, configured to converge the light incident from the light incident surface 2401 to a focal point at which a specified focal length is located; the detecting unit 2302 is disposed at the focus to receive the converged light. The booster 24 has a function of converging light, and is disposed between the detecting unit 2302 and the sensing region 3, a plane of the booster 24 is parallel to the PCB 2301, the detecting unit 2302 is soldered to the PCB 2301, and a detecting direction is perpendicular to the PCB 2301, and light in the sensing region 3 is irradiated to the detecting unit 2302 by a converging effect of the booster 24, so as to enhance a sensing capability of the detecting unit 2302.

The booster 24 includes a fresnel lens, a convex lens or other lens having a light-condensing effect, and the fresnel lens includes a screw-shaped fresnel lens, a saw-tooth fresnel lens, a turtle-shell shaped fresnel lens, a honeycomb-shaped fresnel lens and other shapes of fresnel lenses that can be implemented by those skilled in the art.

Since infrared rays emitted by a human body are very weak, a lens capable of converging the infrared rays of the human body is generally added in the sensing device 2, wherein a fresnel lens is preferred, and as shown in a figure X, the infrared rays can be partially converged through the rear part of the fresnel lens so as to generate a 'blind area' and a 'high-sensitivity area' which are alternately changed on the infrared pyroelectric sensor 2306, so that the infrared rays emitted by the human body when moving can alternately pass through the 'blind area' and the 'high-sensitivity area', and the detection sensitivity of the infrared pyroelectric sensor 2306 is improved. Meanwhile, an optical filter is added at one end of the light emitting surface 2402 of the Fresnel lens, and the optical filter only allows infrared rays with specific wavelengths emitted by a human body to pass through, so that the interference of other infrared rays is removed, and the detection sensitivity is further improved.

It can be seen from the principle that the sensing device 2 can only sense the movement of the human body, and if the human body is still, the sensing device 2 cannot distinguish. Certainly, it is impossible to make the normal human body absolutely still, and the exact point is that the moving range of the human body is larger than the "blind zone" and the "high-sensitivity zone" generated by the fresnel lens, so the farther the human body is away from the sensing device 2, the worse the sensing capability of the sensing device 2 for sensing the motion of the human body is. The utility model discloses a detection distance of induction system 2 can reach 8m, detection angle can reach 120, is a bank at 130 with infrared pyroelectric sensor 2306 complex fresnel lens's detection angle, and when detection angle was greater than 130, the machining precision requirement of its optical line can obviously uprise along with the increase of detection angle to lead to the cost to uprise, the yield is still not good to be guaranteed, so will induction system 2's detection angle sets up to below 130, reduces manufacturing cost.

In some embodiments, the height of the arc surface of the light incident surface 2401 is set to be greater than or equal to 4 mm and less than or equal to 8 mm. The height of the arc surface is greater than or equal to 4 mm, so that the radian of the booster 24 is larger under the condition of the same area, and the booster has a gain effect on the detection distance and the detection angle; and the height of the cambered surface is less than or equal to 8 mm, the overall thickness of the main body is reduced in appearance, and the cambered surface is not too prominent, so that the appearance proportion of the product is rich in aesthetic feeling.

The phase angle positioning slot 2404 is provided for the purpose that since the sensing portion of the infrared pyroelectric sensor 2306 is rectangular, the fresnel lens is circular, and the image field projected by the circular lens is also circular, when the circular image field of the fresnel lens is projected to the sensing portion, the image field only located at the sensing portion triggers the sensing device 2, and the image field located outside the sensing portion does not play a role, so that the optical pattern of the fresnel lens can be designed for the rectangular sensing portion to enhance the sensing capability of the infrared pyroelectric sensor 2306, and accordingly, when the device is installed, the phase angle of the fresnel lens needs to be corresponding to the installation angle of the infrared pyroelectric sensor 2306. By means of the technical scheme, the phase angle of the Fresnel lens can be constant at each time, so that the angle of the Fresnel lens is matched with the angle of the infrared pyroelectric sensor 2306.
