Meanwhile, the target direction 132a is set to adjust the projection direction of the projector 1 to a direction that is better for the user to view.

In one possible implementation, please refer to fig. 6, in which fig. 6 is a schematic diagram of a target area according to an embodiment of the present disclosure. When the microphone 131 receives the voice signals of multiple transmission directions, the voice recognition unit 132 is configured to determine a target area 132b of the voice signal according to the voice signals of multiple transmission directions, and the voice recognition unit 132 is further configured to determine the target transmission direction 132a according to the target area 132 b.

Specifically, in this embodiment, when the microphone 131 receives the voice signals in a plurality of transmission directions, the voice recognition unit 132 determines the target area 132b according to the voice signals in two transmission directions forming the largest included angle. As shown in fig. 6, the target area 132b is a sector area.

It should be understood that the present application is only illustrated by the target region 132b being a sector region, and does not represent that the present application limits the target region 132b to be a sector region, and in a possible embodiment, the target region 132b may also be a polygon, and the speech recognition unit 132 uses the bisector of the area of the target region 132b as the target transmission direction 132a, which is not limited in this application. It is understood that, in the present embodiment, the presence of the target region 132b enables higher stability and performability of the voice operation of the projector 1.

In one possible embodiment, please refer to fig. 7 and 9 together, fig. 7 is a projector according to an embodiment of the present disclosure; fig. 9 is a schematic view of a projection surface according to an embodiment of the present application. The body 10 further includes a depth-sensing camera 17, the depth-sensing camera 17 is disposed corresponding to the light transmission portion 111, the depth-sensing camera 17 is configured to obtain a surface 121 projected by the projection device 12, if a non-coplanar plane 121a in the surface 121 exceeds a preset threshold, the processor 14 sends a driving instruction until the non-coplanar plane 121a in the surface 121 is smaller than the preset threshold, and the processor 14 sends a stop instruction.

Next, the operation principle of the depth camera 17 will be briefly described. Specifically, please refer to fig. 8, and fig. 8 is a schematic diagram of a deep camera frame according to an embodiment of the present disclosure. The depth-sensing camera 17 includes a photodiode sensor 171 and an infrared laser transmitter 172. The infrared laser transmitter 172 transmits infrared light to a target object, the photodiode sensor 171 receives the infrared light reflected by the target object, and the surface 121 structure of the depth sensing camera 17 in the infrared light emitting direction is obtained by calculating the flight time of the infrared light.

Specifically, the preset threshold may be a different value according to different requirements of the required projection accuracy. The projection accuracy requirement is in inverse proportion to the preset threshold, in other words, the higher the projection accuracy requirement is, the smaller the preset threshold is, and conversely, the lower the projection accuracy requirement is, the larger the preset threshold is. In the best case, the surface 121 has only one of the planes 121 a.

It can be understood that when the body 10 is rotated from the first rotation position 10a to the second rotation position 10b, the projection device 12 is not capable of projecting a clear and complete projection picture due to uncertain factors such as different indoor and outdoor environments and obstacles. In the present embodiment, the depth-sensing camera 17 ensures that the projection device 12 can project a clearer and complete projection picture.

In a possible embodiment, please refer to fig. 10 together, and fig. 10 is a schematic view of a supporting body structure provided in an embodiment of the present application. The support body 20 further includes a first support portion 22 and a second support portion 23, the support shaft 21 includes a first rotation portion 21a and a second rotation portion 21b which can rotate relatively, the first support portion 22 is used for supporting the body 10, one end of the first rotation portion 21a is fixedly connected to the first support portion 22, and one end of the second rotation portion 21b is fixedly connected to the second support portion 23.

The intersection portion of the first rotating portion 21a and the second rotating portion 21b of the support rotating shaft 21 is a rotatable portion. When the second supporting portion 23 is fixed, the driving device 16 drives the supporting shaft 21 to rotate the first rotating portion 21a relative to the second rotating portion 21b, so as to drive the first supporting portion 22 to rotate, thereby driving the body 10 to rotate.

In a possible implementation manner, please refer to fig. 11, and fig. 11 is a schematic diagram of a driving apparatus according to an embodiment of the present application. The driving device 16 includes a motor 161, a gear assembly 162, and a rack 163. The motor 161 and the gear assembly 162 are disposed on the first supporting portion 22 and are accommodated in the housing 11. The motor 161 is configured to drive the gear assembly 162 to rotate, the rack 163 is engaged with the gear assembly 162, and the rack 163 is fixed to the first supporting portion 22, and when the motor 161 receives the driving instruction, the motor 161 rotates to drive the gear assembly 162 to rotate, so as to drive the supporting rotating shaft 21 to rotate.

Specifically, the motor 161 rotates according to the driving instruction, and the rotation direction of the motor 161 may be in a clockwise direction or a counterclockwise direction according to the driving instruction. The gear assembly 162 is fixed to a rotating shaft of the motor 161. The shaft rotates, thereby rotating the gear assembly 162.

Specifically, in a possible implementation, please refer to fig. 12, and fig. 12 is a schematic view illustrating a meshing manner between a gear assembly and a rack according to an embodiment of the present application. The gear assembly 162 has a rectangular protrusion 162a and the rack 163 has a rectangular depression 163 a. In the present embodiment, the gear assembly 162 is engaged with the rack 163 in such a manner that the rectangular protrusion 162a is disposed corresponding to the rectangular recess 163 a. In one possible embodiment, please refer to fig. 13 together, and fig. 13 is a schematic view illustrating a meshing manner of a gear assembly and a rack according to another embodiment of the present disclosure. The gear assembly 162 has a semicircular protrusion 162b, the rack 163 has a semicircular recess 163b, and the gear assembly 162 and the rack 163 are engaged in such a manner that the semicircular protrusion 162b and the semicircular recess 163b are correspondingly disposed. It is understood that the convex portion of the gear assembly 162 and the concave portion of the rack 163 may have the same other shapes, and the present application is not limited thereto.

Specifically, when the body 10 is in the first rotational position 10a, the meshing position of the gear assembly 162 and the rack 163 is one end of the rack 163, and when the body 10 is in the second rotational position 10b, the meshing position of the gear assembly 162 and the rack 163 is the other end of the rack 163.

Specifically, please refer to fig. 14 together, in a possible embodiment, fig. 14 is a schematic view illustrating a fixing manner of the rack and the first supporting portion according to an embodiment of the present application. The side of the rack 163 facing away from the gear assembly 162 is coated with at least a part of fixing glue 30, and the rack 163 is adhered and fixed to the first support part 22 by the fixing glue 30.

Specifically, in another possible embodiment, referring to fig. 15 together, fig. 15 is a schematic view illustrating a fixing manner of a rack and a first supporting portion according to another embodiment of the present disclosure. The present embodiment is different from the previous embodiment in the fixing manner of the rack 163 and the first support part 22 in that, in the present embodiment, as shown in fig. 15, the first support part 22 has grooves 221 at both ends contacting the solid glue 30. It can be understood that when the amount of the solid glue 30 is too much, the solid glue 30 overflows to the groove 221 and is accommodated in the groove 221. The side of groove 221 adjacent to solid glue 30 has a first roughness and the side of groove 221 facing away from solid glue 30 has a second roughness. It is understood that, in order to enable the solid glue 30 to be better accommodated in the groove 221, the first roughness is smaller than the second roughness. In this embodiment, the groove 221 has a trapezoidal structure, and in a possible embodiment, the groove 221 may also have an arc structure with a larger opening ratio.

It can be understood that, in this embodiment, the groove 221 is configured to receive the solid glue 30 overflowing, and serves to prevent the solid glue 30 overflowing from directly contacting with the support rotating shaft 21 or other components of the projector 1 during the rotation of the projector 1, which may cause a failure of the projector 1.

In a possible embodiment, please refer to fig. 16, and fig. 16 is a schematic view illustrating a fixing manner of a rack and a first supporting portion according to another embodiment of the present disclosure. The rack 163 has a through hole 1631, the through hole 1631 is penetrated by a fixing member 1632, one end of the fixing member 1632 is located at a side of the rack 163 departing from the first supporting portion 22, and the other end of the fixing member 1632 is embedded in the first supporting portion 22. It is understood that the rack 163 and the first support 22 have various fixing manners, and the present application is not limited thereto.

It can be understood that, in the present embodiment, the rack 163 in the driving device 16 saves space relative to the way of the sliding groove, so that the volume of the projector 1 can be further reduced. And the rack 163 is mechanically simple, reducing the material cost of the projector 1.

In one possible embodiment, please refer to fig. 17, and fig. 17 is a schematic view of a gear assembly according to an embodiment of the present disclosure. The gear assembly 162 includes a first gear 1621 and a second gear 1622, and the rotation speed of the supporting shaft 21 is adjusted by the rotation speed of the gear assembly 162 relative to the motor 161.

Specifically, as shown in fig. 17, the first gear 1621 is engaged with the second gear 1622, and a radius of the first gear 1621 is smaller than a radius of the second gear 1622. The first gear 1621 is fixed to the motor 161, and the second gear 1622 is engaged with the rack 163. The angular velocities of the first gear 1621, the second gear 1622, and the motor 161 are equal. From the linear velocity equation of the circle:

V＝ωR

it is understood that, when the angular velocity ω is the same, the linear velocity V at the radius increases as the radius R of the circle increases. It can be understood that, in the present embodiment, with a smaller rotation speed of the motor 161, the second gear 1622 can be controlled to rotate at a larger linear speed, so as to drive the body 10 to rotate at a larger linear speed. Effectively avoided because of the too big result in of body 10 quality, perhaps motor 161 rotation dynamics is not enough, leads to the unable pivoted problem of body 10.

In one possible embodiment, please refer to fig. 18, in which fig. 18 is a schematic view of a comparison of rotation speeds provided in an embodiment of the present application. The memory 15 stores a comparison table 151 of the rotation position of the supporting spindle 21 compared to the rotation position and the rotation speed of the motor 161, and when the rotation speed of the motor 161 is less than the rotation speed of the corresponding position in the comparison table 151 during the rotation of the motor 161, the processor 14 sends a stop instruction to the driving device 16, where the stop instruction is used to control the driving device 16 to stop rotating.

Specifically, as shown in fig. 18, the lookup table 151 includes positions M and N, and a dashed double-headed arrow indicates the rotation direction of the body 10. When the body 10 rotates from the first rotation position 10a to the second rotation position 10b, the M corresponds to an acceleration ending position of the body 10 from the first rotation position 10a to the M, and the N corresponds to a deceleration starting position of the body 10 from the N to the second rotation position 10 b. Conversely, when the body 10 rotates from the second rotation position 10b to the first rotation position 10a, the N corresponds to an acceleration ending position of the body 10 from the second rotation position 10b to the N, and the M corresponds to a deceleration starting position of the body 10 from the M to the first rotation position 10 a. When the body 10 is between M and N, the motor 161 rotates at a constant speed. If the rotation speed of the motor 161 is lower than that of the corresponding position in the look-up table 151 due to some special conditions, for example, due to a failure of the motor 161, or the body 10 cannot rotate continuously when encountering a foreign object during rotation, the processor 14 sends a stop instruction to the driving device 16, where the stop instruction is used to control the driving device 16 to stop rotating.

It can be understood that, in the present embodiment, the presence of the lookup table 151 makes the control of the projector 1 more stable for the user, and at the same time, prevents accidental damage to the projector 1 from some special situations, and increases the service life of the projector 1.

In a possible embodiment, please refer to fig. 19 together, and fig. 19 is a projector according to a second embodiment of the present application. The projector 1 further comprises a rocker arm device 18, the rocker arm device 18 is fixed to the support rotating shaft 21 through a fixing member 19 (as shown in fig. 10), the fixing member 19 has a locked state, and when the fixing member 19 is in an unlocked state, the support rotating shaft 21 is driven to rotate by rotating the rocker arm device 18.

Specifically, when the voice signal "rotate" received by the voice receiving device 13 matches with the "rotation" of the preset instruction, the processor 14 sends the driving instruction, the driving device 16 drives the supporting rotating shaft 21 to rotate, the rocker arm device 18 is used to rotate the supporting rotating shaft 21, and the processor can detect the sound production change of the rotating speed of the motor 161 according to the comparison table 151 and send the stop instruction.

Specifically, as shown in fig. 19, the swing arm device 18 includes two swing arms 18a and a grip 18b, and both ends of the swing arm 18a are zigzag-connected to both ends of the grip 18 b. The other two ends of the rocker arm 18a are fixedly connected to the first rotating portion 21a through the fixing member 19. When the handle 18b is located at a side facing away from the body 10 relative to the fixture 19, in other words, when the handle 18b is pressed down relative to the fixture 19, the fixture 19 is in an unlocked state. Conversely, when the grip 18b is located at a side adjacent to the body 10 with respect to the fixed member 19, in other words, when the swing arm device 18 is pulled up with respect to the fixed member 19, the fixed member 19 is in a locked state. When the fixing piece 19 is in an unlocked state, the supporting rotating shaft 21 is driven to rotate by rotating the rocker arm device 18.

Specifically, in a possible embodiment, please refer to fig. 20 and 21 together, fig. 20 is a schematic view of a state of a fixing element according to an embodiment of the present application; fig. 21 is a schematic view of another state of the fixing element according to an embodiment of the present application. The rocker arm device 18 has a first positioning portion 18c, the fixing member 19 has a plurality of second positioning portions 19a arranged at intervals, and an accommodating space 19b is provided between two adjacent second positioning portions 19a, as shown in fig. 20, when the fixing member 19 is in an unlocked state, the first positioning portion 18c is located outside the accommodating space 19 b; as shown in fig. 21, when the fastener 19 is in the locked state, the first positioning portion 18c is accommodated in the accommodating space 19 b.

Specifically, as shown in fig. 19, two adjacent second positioning portions 19a are connected by a bent cavity wall 19c, and the cavity wall 19c and the two adjacent second positioning portions 19a form the accommodating space 19 b. The first positioning portion 18c and the second positioning portion 19a are elastic protrusions, and when the rocker arm device 18 is pressed down relative to the body 10, the first positioning portion 18c is ejected from the receiving space 19b of the second positioning portion 19a, and at this time, the support rotating shaft 21 is driven to rotate by rotating the rocker arm device 18. When the rocker arm device 18 is pulled up relative to the body 10, the first positioning portion 18c is accommodated in the accommodating space 19b of the second positioning portion 19a, and the fixing member 19 is in a locked state, so that the support rotating shaft 21 cannot be rotated. It should be understood that the present application only exemplifies the structures of the fixing member 19 and the rocker arm device 18 shown in fig. 19, 20, and 21, and does not represent that the present application limits the structures of the fixing member 19 and the rocker arm device 18.

It is understood that, in the present embodiment, the adjustment of the projection direction of the projector 1 is realized by combining the manual adjustment and the intelligent adjustment of the voice control. When the projection direction of the projector 1 needs to be adjusted finely, the direction of the projector 1 can be adjusted through the rocker arm device 18, and the requirement for adjusting the projection direction of the projector 1 is met.
