Detailed Description
The application provides a camera telescopic assembly, which can avoid scratch of a camera and can keep a larger field angle of the camera.
The application also provides an electronic product comprising the camera telescopic assembly, which can avoid the scratch of the camera and can keep a larger field angle of the camera.
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1-5, an embodiment of the present application provides a camera telescopic assembly, which includes a camera mount 2, a rack 6, a gear set, and a driving component 9, wherein the camera mount 2 is used for mounting a camera 1; the rack 6 is fixedly connected with the camera mounting seat 2 and drives the camera mounting seat 2 to linearly reciprocate together; the gear set is in transmission connection with the rack 6; the drive member 9 is in driving connection with the gear set for transmitting power to the gear set and the rack 6.
The working principle of the camera telescopic component is as follows: the power of the driving part 9 is transmitted to the rack 6 through the gear set, and the rack 6 drives the camera mounting seat 2 to do linear reciprocating motion, so that the camera 1 stretches out of the electronic product when in use and retracts into the electronic product when not in use. Thereby avoiding the scratch of the camera and simultaneously keeping a larger field angle of the camera.
Optimizing the gear set, which in this embodiment comprises a driving gear 5, a first driven gear 4 and a first coaxial gear, wherein the driving gear 5 is connected with a driving member 9; the first driven gear 4 is meshed with the driving gear 5; the first coaxial gear is coaxially fixed with the first driven gear 4, and the first coaxial gear is meshed with the rack 6. When the gear set works, the driving part 9 drives the driving gear 5 to rotate, the driving gear 5 drives the first driven gear 4 to rotate, the first coaxial gear rotates together with the first driven gear 4, and the first coaxial gear drives the rack 6 to move along a straight line. By changing the driving direction of the driving part 9, the rack 6 is finally moved back and forth in a straight line, so that the camera 1 is extended and retracted.
Further, as shown in fig. 1 to 4, the first coaxial gear is a first sector gear 3. So configured, the first driven gear 4 rotates with the first sector gear 3, when the first sector gear 3 starts to mesh with the rack 6, the first sector gear 3 drives the rack 6 to move, and when the first sector gear 3 is disengaged from the rack 6, the rack 6 stops moving. The distance that the first sector gear 3 drives the rack 6 to move is the distance that the camera 1 needs to extend, when the camera 1 needs to retract, the driving part 9 is made to reversely drive the first sector gear 3 to reversely rotate, so that the rack 6 reversely moves by the same distance and retract to the original position. The distance of the reciprocating movement of the rack 6 is conveniently controlled by the first sector gear 3. Of course, the first coaxial gear may also be a circular gear, only the distance the rack 6 moves needs to be controlled by the driving member 9.
Further, in the present embodiment, the gear set further includes a second driven gear 8 and a second sector gear 7 on the basis of the first driven gear 4 and the first sector gear 3, wherein the second driven gear 8 is in driving connection with the driving gear 5, and the power of the driving gear 5 is transmitted to the second driven gear 8; the second sector gear 7 is coaxially fixed with the second driven gear 8, and the second sector gear 7 is engaged with the rack 6, and when the driving member 9 is driven in the same direction, the second sector gear 7 and the first sector gear 3 are alternately engaged with the rack 6, and the second sector gear 7 is opposite to the direction in which the first sector gear 3 drives the rack 6 to move.
By this arrangement, the direction of the drive member 9 does not need to be changed, and the movement of the rack 6 is reversed by the gear set itself. The driving part 9 can drive the driving gear 5 to rotate in a single direction, the driving gear 5 is in transmission connection with the second driven gear 8 while the driving gear 5 is meshed with the first driven gear 4, the first driven gear 4 and the second driven gear 8 are simultaneously rotated, and accordingly, the first sector gear (3) and the second sector gear 7 are simultaneously rotated, but when the first sector gear 3 is meshed with the rack 6, the second sector gear 7 is disengaged from the rack 6, and when the second sector gear 7 is meshed with the rack 6, the first sector gear 3 is disengaged from the rack 6, and the direction in which the first sector gear 3 drives the rack 6 to move is opposite to the direction in which the second sector gear 7 drives the rack 6 to move. Assuming that the first sector gear 3 drives the rack 6 to extend, the second sector gear 7 drives the rack 6 to retract; or the second sector gear 7 drives the rack 6 to extend, the first sector gear 3 drives the rack 6 to retract. Since the driving direction of the driving part 9 does not need to be changed, the alternate action of the extension, retraction, extension, and retraction of the rack bar 6 can be achieved as long as the driving part 9 is driven in a single direction. Of course, the driving direction of the driving part 9 can be changed arbitrarily, and the gear set can also realize the extension and retraction of the rack 6, and the telescopic function of the camera 1 can be realized no matter in which direction the driving part 9 is driven.
As shown in fig. 1-4, the arrangement of the gear set is optimized, in this embodiment, the rack 6 is a double-sided rack, i.e. teeth are provided on both sides of the rack 6, the first sector gear 3 and the second sector gear 7 are respectively meshed with both sides of the double-sided rack, and the second driven gear 8 is meshed with the driving gear 5, i.e. the driving gear 5 is meshed with both the first driven gear 4 and the second driven gear 8. The first sector gear 3 and the second sector gear 7 are also alternately meshed with the rack 6, and the rotation directions of the first sector gear 3 and the second sector gear 7 are the same, and as the first sector gear 3 and the second sector gear 7 are respectively meshed with the two side teeth of the rack 6, the directions of driving the rack 6 by the first sector gear 3 and the second sector gear 7 are opposite, so that the extension and the retraction of the rack 6 are realized.
Further, the first driven gear 4 and the second driven gear 8 are symmetrically arranged on two sides of the rack 6, the distance between any two points on the sector teeth of the first sector gear 3 and the sector teeth of the second sector gear 7, which are positioned at the same position, is always unchanged, and the connecting line between the two points is always perpendicular to the moving direction of the rack 6. If the driving part 9 drives the driving gear 5 to rotate along a single direction, the first sector gear 3 is meshed with one side of the rack 6 to drive the rack 6 to move along the first direction, when the first sector gear 3 is disengaged and rotated for a certain time, the second sector gear 7 starts to be meshed with the other side of the rack 6 and drives the rack 6 to move reversely, and after the second sector gear 7 is disengaged and rotated for the same time, the first sector gear 3 is meshed with one side of the rack 6 again to drive the rack 6 to move along the first direction, and the cycle is sequentially and alternately performed. Thus, the intervals of the reciprocating movement of the rack 6 are the same. Of course, the first sector gear 3 and the second sector gear 7 can alternatively mesh with the double-sided racks at different intervals of rotation, but at different intervals of reciprocating movement of the racks.
In this embodiment, the gear set may be arranged in other ways, for example, the rack 6 is a single-sided rack, the rotation direction of the second driven gear 8 is opposite to that of the first driven gear 4, the second driven gear 8 is in driving connection with the driving gear 5 through a transition gear set, or the second driven gear 8 is in driving connection with the first driven gear 4. That is, the first sector gear 3 and the second sector gear 7 are both engaged with the one-side teeth of the one-side rack, but since the rotation directions of the first driven gear 4 and the second driven gear 8 are opposite, the rotation directions of the first sector gear 3 and the second sector gear 7 are opposite, and the movement directions of the first sector gear 3 and the second sector gear 7 driving the rack 6 are just opposite, so long as they are alternately engaged with the rack 6. In order to ensure that the rotation directions of the first driven gear 4 and the second driven gear 8 are opposite, since the first driven gear 4 is meshed with the driving gear 5, the second driven gear 8 is in transmission connection with the driving gear 5 through a transition gear set, and the number of gears of the transition gear set is one, three and other odd numbers. Or the second driven gear 8 is in driving connection with the first driven gear 4, in particular directly engaged or in driving connection via an even number of transition gears.
In this embodiment, the driving part 9 is a knob, and the driving gear 5 is driven to rotate by manually rotating the knob, so that if the gear set capable of automatically changing the moving direction of the rack 6 in the above embodiment is adopted, the telescopic function of the camera 1 can be realized no matter in which direction the knob is rotated. Of course, if the gear set cannot automatically change the moving direction of the rack 6, the telescopic function of the camera 1 can be realized by changing the rotating direction of the knob.
In addition, the driving part 9 may be an electric driving part, specifically may be a motor, and the controller controls the rotation direction of the motor to implement the telescopic function of the camera 1.
Further, in the present embodiment, the rack 6 is moved in the axial direction of the camera 1, so that the camera expansion assembly drives the camera 1 to expand and contract in the axial direction thereof. By the arrangement, the camera 1 does not need to extend a large distance, and the extending distance can enable the angle of view of the camera 1 to meet the requirement.
As shown in fig. 5 and fig. 6, based on the camera telescopic assembly described in any of the above embodiments, the embodiment of the present application further provides an electronic product, which includes a camera 1 and a housing 10, and further includes the camera telescopic assembly described in any of the above embodiments, a camera extending hole is formed in the housing 10, the camera telescopic assembly is installed in the housing 10, and the camera 1 is installed on the camera mounting seat 2.
The electronic product drives the camera 1 to extend out of the shell 10 through the camera telescopic assembly when in use, and retract into the shell 10 when not in use, so that the scratch of the camera 1 is avoided, and the larger field angle of the camera 1 is reserved.
Further, in this embodiment, the first guiding structure is disposed in the housing 10, the rack 6 of the camera telescopic assembly is disposed with the second guiding structure moving in cooperation with the first guiding structure, and the rack 6 is reciprocally moved along a prescribed straight line by cooperation of the first guiding structure and the second guiding structure.
Still further, in this embodiment, the first guiding structure is a guiding and positioning column, the second guiding structure is a guiding slot 61, and the guiding and positioning column includes an extended position guiding and positioning column 102 and a retracted position guiding and positioning column 101, the extended position guiding and positioning column 102 is disposed away from the camera 1, and the retracted position guiding and positioning column 101 is disposed close to the camera 1. That is, the guide positioning column not only plays a role of guiding in cooperation with the guide groove 61, but also can limit the stroke of the reciprocating movement of the rack 6. When the rack bar 6 is extended to the point where one end of the guide groove 61 is in contact with the extended position guide positioning column 102, the rack bar 6 cannot be extended further, and when the rack bar 6 is retracted to the point where the other end of the guide groove 61 is in contact with the retracted position guide positioning column 101, the rack bar 6 cannot be retracted further.
Of course, the first and second guide structures may also be other mating structures, such as, for example, interchange of positions on the rack 6 and housing 10, etc. As long as the guiding positioning can be achieved.
In this embodiment, a knob is mounted on the housing 10, and the knob is connected with the driving gear 5 by dispensing.
In this embodiment, the electronic product is an AR device (virtual reality device), a VR device (augmented reality device), a camera, a mobile phone, or a computer, where the AR device and the VR device are preferably head-mounted devices.
