Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 3, the embodiment of the present invention provides a transmission assembly 1, which includes a gear 11 and a rack 12, wherein the gear 11 is used for connecting with a driving mechanism 2, and the rack 12 is used for connecting with a driven component; the rack 12 is provided with a first meshing section 121, and the first meshing section 121 is provided with first meshing teeth.
The gear 11 includes a second engaging section 111 and a non-engaging section 112, the second engaging section 111 is provided with a second engaging tooth engaged with the first engaging tooth, and when the non-engaging section 112 moves to a first predetermined position, the gear 11 is disengaged from the rack 12.
The non-meshing section 112 is understood to be a portion of the gear 11 where no meshing teeth are provided.
Wherein, the driving mechanism 2 can be a motor, and the driving mechanism 2 can be connected with the gear 11 through a rotating shaft.
The first predetermined position may be a position where the non-engaging section 112 is located when the non-engaging section 112 faces the first engaging section 121, or a position where the non-engaging section 112 is located when the second engaging section 111 is disengaged from the first engaging section 121.
The transmission assembly 1 of the embodiment of the present invention is applicable to transmission of a driven component, that is, the driven component is a driven component, for example, a telescopic camera 3, and fig. 1 to 3 show an embodiment of applying the transmission assembly 1 of the embodiment of the present invention to the camera 3, and more specifically, fig. 1 to 3 show an embodiment of applying the transmission assembly 1 of the embodiment of the present invention to the camera 3 of an electronic device (for example, a mobile phone, a tablet computer, etc.). For convenience of description, the following description will be made by taking the case where the transmission assembly 1 is applied to a retractable camera 3 provided in a mobile phone.
During operation, when the user needs to use camera 3 to shoot, need stretch out camera 3 from the cell-phone casing. The user can input a shooting instruction, under the condition that the mobile phone receives the shooting instruction, the drive mechanism 2 can be controlled to rotate in the first rotating direction, the gear 11 is driven by the drive mechanism 2 to rotate in the first rotating direction, the gear rack 12 is pushed by the meshing teeth to move in the extending direction of the camera 3, and the gear rack 12 drives the camera 3 to move in the extending direction of the camera 3, as shown in fig. 2. Until the camera 3 extends to the preset position, the driving mechanism 2 stops operating, and when the camera 3 extends to the second preset position, the non-meshing section 112 of the gear 11 moves to the first preset position, and at this time, the gear 11 is separated from the rack 12, as shown in fig. 3. Thus, when the camera 3 is accidentally impacted by external force (for example, the mobile phone is accidentally dropped), the external force applied to the camera 3 cannot be transmitted to the gear 11 and the driving mechanism 2 along the rack 12 because the gear 11 is separated from the rack 12, so that the gear 11 and the driving mechanism 2 are effectively prevented from being damaged due to the impact of the external force applied to the camera 3.
After the user finishes shooting, the camera 3 may be retracted into the mobile phone case. The user can input a shooting end instruction, under the condition that the mobile phone receives the shooting end instruction, the drive mechanism 2 can be controlled to rotate in the second rotating direction, the gear 11 is driven by the drive mechanism 2 to rotate in the second rotating direction, the gear rack 12 is pushed by the meshing teeth to move in the retracting direction of the camera 3, and the gear rack 12 drives the camera 3 to move in the retracting direction of the camera 3 until the camera 3 is retracted into the mobile phone shell.
Optionally, the circumferential length of the second engaging section 111 is greater than the circumferential length of the non-engaging section 112.
Since the non-engagement section 112 of the gear 11 is not engaged with the first engagement section 121 of the rack 12, in fact, when the non-engagement section 112 of the gear 11 rotates to the first predetermined position, the gear 11 is interpreted as being in an idle rotation state. In order to improve the working efficiency of the driving mechanism 2 when pushing the camera 3 to extend or retract and reduce unnecessary energy loss, the circumferential length of the second engaging section 111 should be greater than the circumferential length of the non-engaging section 112. Specifically, the circumferential length of the second meshing section 111 is greater than or equal to two-thirds of the circumference of the gear 11 and less than or equal to three-quarters of the circumference of the gear 11.
Optionally, the length of the first engagement section 121 is greater than the circumferential length of the second engagement section 111.
In general, the length of the first engagement section 121 cannot be smaller than the circumferential length of the second engagement section 111 unless the maximum travel of the drive mechanism 2 is smaller than the circumferential length of the second engagement section 111 of the gear wheel 11. In the case where the maximum travel of the drive mechanism 2 is greater than the second engagement section 111 of the gear wheel 11, the length of the first engagement section 121 should be greater than the circumferential length of the second engagement section 111 to ensure that the rack 12 provides sufficient engagement length for the gear wheel 11 at any travel within the maximum travel of the drive mechanism 2.
Optionally, the length of the first engagement section 121 is greater than or equal to the circumference of the gear 11.
In this way, it is further ensured that the rack 12 can provide the gear 11 with a sufficient meshing length.
Alternatively, the single stroke of the drive mechanism 2 in either rotational direction is an integer multiple of the circumference of the gear wheel 11.
Generally, when shooting with the camera 3 is required, the mobile phone controls the driving mechanism 2 to push the camera 3 to a predetermined position through a single stroke in the first rotation direction, that is, to push the camera 3 to the predetermined position, which is realized through a continuous one-stroke of the driving mechanism 2. Accordingly, the mobile phone will control the driving mechanism 2 to retract the camera 3 into the mobile phone housing with a single stroke in the second rotational direction. Therefore, a single stroke of the driving mechanism 2 in either rotational direction is set to be an integral multiple of the circumference of the gear 11, so that no matter how many times the driving mechanism 2 passes through the single stroke, the non-meshing section 112 of the gear 11 can be moved to the first predetermined position, at which time the gear 11 is disengaged from the rack 12. Thus, the control mechanism for the drive mechanism 2 can be simplified, and the reliability of the transmission assembly can be further improved.
It should be noted that it is possible to arrange two or more cameras side by side along the extending direction of the camera 3 to realize more shooting functions, and then the driving mechanism 2 can be controlled to extend different cameras through a plurality of single strokes in sequence. The different times of single strokes may be different or the same, but are preferably integer multiples of the circumference of the gear 11. For example, the number of the cameras 3 is two, the first camera is extended, and the gear 11 needs to rotate for two circles, that is, the first single stroke of the driving mechanism 2 is twice the circumference of the gear 11; then, the second camera is extended, and the gear 11 still needs to rotate one circle, i.e. the second single stroke of the driving mechanism 2 is the circumference of the gear 11.
The embodiment of the invention also provides a camera component, which comprises a camera 3, a driving mechanism 2 and any one of the transmission components 1, wherein a rack 12 of the transmission component 1 is connected with the camera 3, and a gear 11 of the transmission component 1 is connected with the driving mechanism 2.
For the specific implementation of the camera assembly, reference may be made to the above description, and the same technical effects can be achieved.
The embodiment of the invention also provides electronic equipment which comprises a shell, a driven part, a driving mechanism and any one of the transmission assemblies, wherein the driven part, the driving mechanism and the transmission assembly are all arranged in the shell, and the shell is provided with an opening for extending out or retracting the driven part;
the rack of the transmission assembly is connected with the driven part, the gear of the transmission assembly is connected with the driving mechanism, and when the driven part extends to the second preset position, the gear 11 is separated from the rack 12.
Optionally, the driven part is at least one of a camera, a sensor, a fingerprint identification module, a receiver and a light supplement lamp.
