As shown in fig. 1, an angle adjusting mechanism suitable for a projection assembly is provided, the angle adjusting mechanism includes a fixing base 100, a bracket 200, a shift lever 300 and a lifting member 400, the fixing base 100 is rotatably connected to the bracket 200 around a rotation axis, and the fixing base 100 is used for supporting the projection assembly; one end of the driving lever 300 is hinged to the lifting member 400, and the other end of the driving lever 300 is connected to the fixing base 100, and the lifting member 400 drives the driving lever 300 to drive the fixing base 100 to rotate around the axial direction of the rotating shaft when performing lifting movement.
The projection assembly may be a projector, the fixing base 100 may have various shapes, such as a square shape and a triangular shape, and the shape of the projection assembly adjusted according to actual needs is determined, and the fixing base 100 is provided in this embodiment as a barrel shape. Toggle 300 may be a rigid rod. The elevation member 400 is driven by a motor to perform an elevation motion. One end of the lever 300 is hinged to the lifting member 400, and the lifting member 400 moves up and down to drive the lever 300 to move up and down. Because the other end of the shift lever 300 is connected to the fixing base 100, the lifting movement of the shift lever 300 drives the fixing base 100 to rotate around the axial direction of the shaft, so as to adjust the angle of the projection assembly.
In one embodiment, the lifting member 400 is a screw pair structure driven by a motor, and one end of the lever 300 is hinged to a nut element of the screw pair structure.
The screw assembly is provided with a nut element to fasten the shift lever 300, thereby preventing the shift lever 300 from falling off when the lifting member 400 performs a lifting motion, thereby affecting the adjustment of the rotation angle.
In one embodiment, as shown in fig. 2, the lifting member 400 further includes a rotating base 401 and an elastic member 402, the rotating base 401 is rotatably connected to the nut element, a first guide groove 500 is formed on the rotating base 401, the elastic member 402 is disposed in the first guide groove 500, one end of the shift lever 300 is inserted into the first guide groove 500 and fixedly connected to one end of the elastic member 402, and the other end of the elastic member 402 is connected to the first guide groove 500. With such an arrangement, when the lifting member 400 is lifted, the driving lever 300 can be conveniently driven to move up and down, and the elastic member 402 plays a role of stretching the driving lever 300.
In one embodiment, the fixing base 100 is provided with a receiving groove 600 for supporting the projection module. As shown in fig. 3, the receiving groove 600 is a hole in the center of the fixing base 100, and when the projection assembly needs to be adjusted in angle, the projection assembly can be placed in the receiving groove 600. The shape of the receiving groove 600 is not limited to the shape provided in the present embodiment, and the specific shape is set according to actual needs.
In one embodiment, the receiving groove 600 is a cylinder, and an axis of the rotating shaft coincides with an axis of the cylindrical receiving groove 600. The arrangement is that when the fixing base 100 rotates, the cylindrical receiving groove 600 can rotate at the same angle as the fixing base 100, so that the angle of the projection assembly can be adjusted along with the rotation of the fixing base 100.
In one embodiment, as shown in fig. 4, a plurality of second guide grooves 700 are formed in the fixing base 100 along the circumferential direction of the rotating shaft, and the other end of the shift lever 300 is inserted into one of the second guide grooves 700 and connected to the fixing base 100.
Wherein, the circumferential direction is around the axis direction of the cylinder (perpendicular to the axis and perpendicular to the radius of the cross section), and the plurality of second guide grooves 700 are provided for adjusting the rotation angle in stages, so as to obtain a more precise angle. The plurality means a number of 2 or more. As shown in fig. 5, the direction of the dotted arrow indicates the moving direction of the object, when the motor drives the lifting member 400 to perform the lifting motion, the driving lever 300 drives the fixing base 100 to rotate counterclockwise, and the second guiding slot 700 also rotates counterclockwise, at this time, the angle of the projection assembly is being adjusted.
In one embodiment, as shown in fig. 4, the number of the second guide grooves 700 is 6, and 6 second guide grooves 700 are uniformly arranged on the fixing base 100 along the circumferential direction of the rotating shaft.
Circumference is even promptly the angle is even, and the equal angular interval of second guide way 700 sets up on fixing base 100, is driven rotatory a week by driving lever 300 when fixing base 100, and the fixing base has rotated 360. The other end of the driving lever 300 is inserted into one of the second guiding grooves 700 to rotate, which corresponds to one rotation of the projection assembly by 60 °.
The number of the second guide grooves 700 is not limited to 6, and may be appropriately adjusted according to actual adjustment. For example, the number of the second guide grooves 700 may be 12, and each second guide groove 700 corresponds to a projection assembly that can be rotatably adjusted by 30 °.
In one embodiment, the other end of the driving lever 300 is inserted into one of the second guide slots 700, and the second guide slot 700 is detachably connected to the fixing base 100. Since the other end of the driving lever 300 is inserted into the second guide groove 700 to be detachably connected to the fixing base 100, the driving lever 300 can be easily assembled when it is necessary to replace the driving lever.
In one embodiment, the length of the toggle lever 300 is adjustable. To facilitate removal of shifter lever 300, the length of shifter lever 300 may be adjusted. For example, since one end of the lever 300 is hinged to the elevation member 400, when the lever 300 needs to be removed from the fitted second guide groove 700, the lever 300 is contracted, that is, the length of the lever 300 is shortened, to achieve the removal from the fitted second guide groove 700.
In one embodiment, the diameter of the other end of the shift lever 300 is smaller than the diameter of the second guide groove 700. As shown in fig. 6, to facilitate the detachment between the shifter lever 300 and the second guide groove 700, the other end of the shifter lever 300 has a diameter smaller than that of the second guide groove 700. Such an arrangement prevents the shift lever 300 from easily colliding with the fixing base 100 during the disassembly process, and affecting the adjusted rotation angle. For example, the diameter of the other end of the lever 300 is 300mm, and the diameter of the second guide groove 700 is 350 mm.
The angle adjusting mechanism suitable for the projection assembly drives the lifting component to do lifting motion to drive the deflector rod, so that the fixed seat supporting the projection assembly rotates to adjust the angle of the projection assembly. The lifting mechanism is simple to operate, the projection assembly does not need to be directly rotated and adjusted in a manual mode, and the lifting mechanism can be driven by the motor to move up and down to drive the lifting rod to rotate the fixed seat to adjust the angle of the projection assembly, so that the adjustment convenience and the adjustment precision of the projection assembly are improved.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
