Detailed Description
For better understanding of the objects, technical solutions and effects of the present invention, the present invention will be further explained with reference to the accompanying drawings and examples. Meanwhile, the following described examples are only for explaining the present invention, and are not intended to limit the present invention.
It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
The terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", and the like indicate orientations or positions based on the orientations or positions shown in the drawings, and are for convenience of description only and not to be construed as limiting the technical solution.
The terms "first", "second" and "first" are used merely for descriptive purposes and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features.
The meaning of "plurality" is two or more unless specifically defined otherwise.
As shown in fig. 1-4, a single-motor 1 dual-drive mechanism includes a motor 1, a first stressed moving mechanism and a second stressed moving mechanism, an output shaft 101 of the motor 1 is provided with an upper gear 2 and a lower gear 3, the motor 1 drives the upper gear 2 and the lower gear 3 to rotate synchronously, and the two gears can slide up and down synchronously along the output shaft 101, when the upper gear 2 and the lower gear 3 slide up to corresponding first positions (i.e. the upper gear 2 slides to the first position of the upper gear 2, and the lower gear 3 slides up to the first position of the lower gear 3), the upper gear 2 is engaged with the first stressed moving mechanism, and the lower gear 3 is disengaged from the second stressed moving mechanism, so that the motor 1 drives the first stressed moving mechanism; when the upper gear 2 and the lower gear 3 slide down to the corresponding second positions, the upper gear 2 is separated from the first force-bearing moving mechanism, the lower gear 3 is meshed with the second force-bearing moving mechanism, and the motor 1 drives the second force-bearing moving mechanism at the moment.
The term "synchronization" in the present invention is a synchronization in a broad sense, and does not mean that the upper gear and the lower gear are in the same state at every moment. That is, the upper gear moves downwards to drive the lower gear to move downwards, and at the moment of state change, the lower gear can have instant state change delay relative to the upper gear.
Therefore, compared with the prior art that two motors are used for respectively driving two stressed moving mechanisms, the single-motor double-drive mechanism can drive the two stressed moving mechanisms to move by finishing one motor, so that the structure of the equipment is simplified, and the size of the equipment is reduced.
In this embodiment, the output shaft 101 of the motor 1 is provided with a threaded axial screw 4, the upper gear 2 and the lower gear 3 are both sleeved on the axial screw 4 and are in threaded connection with the axial screw 4, and when the axial screw 4 rotates along with the output shaft 101 of the motor 1, the upper gear 2 and the lower gear 3 can slide up and down along the screw thread on the axial screw 4.
The screw thread on the axis screw 4 rotates clockwise and extends along the direction from bottom to top, and the inner ring side walls of the upper gear 2 and the lower gear 3 are both provided with thread grooves which are in the same direction and are matched with the screw thread. When the gear is subject to external force and the rotation state is limited, the upper gear 2 and the lower gear 3 will slide along with the rotation of the motor 1, for example, the upper gear 2 slides down along the screw thread when being blocked, and the lower gear 3 slides up along the screw thread when being blocked.
In other embodiments, the screw thread may be designed to be counterclockwise, and the structure merely changes the relationship between the rotation direction of the motor 1 and the up-down direction of the two gears, and does not affect the function implementation, which is the protection scope of the present invention, for example, in this embodiment, the screw thread of the axis screw 4 is clockwise, so when the motor 1 rotates counterclockwise, the gear can slide up, and when the motor 1 rotates clockwise, the gear can slide down; on the contrary, if the screw thread of the axial screw 4 is counterclockwise, the gear may slide up when the motor 1 rotates clockwise, and the gear may slide down when the motor 1 rotates counterclockwise.
An upper spring 5 is arranged between the upper gear 2 and the lower gear 3, a lower spring 6 is arranged between the lower gear 3 and the motor 1, and the upper spring 5 is used for transmitting acting force between the two gears to enable the two gears to synchronously slide up and down. For example, when the upper gear 2 slides downwards to the second position, the lower gear 3 is pushed by the upper spring 5 to synchronously slide downwards, and when the lower gear 3 slides upwards to the first position under the action of the lower spring 6, the upper gear 2 is pushed by the upper spring 5 to synchronously slide upwards; the upper spring 5 is used as a power transmission component of the two gears, and can provide a torsion buffering effect between the two gears, so that the gears are smoother in the sliding and state changing processes, the burden of the motor 1 is reduced, for example, at the moment that the rotating state of the upper gear 2 is blocked and slides, the lower gear 3 still rotates along with the motor 1, the upper gear 3 and the lower gear 3 have a rotating speed difference, and after the upper gear 2 is completely separated from the first stress moving mechanism, the two gears continue to rotate synchronously.
The lower spring 6 is used to restore the lower gear 3 to the first position, and as the lower gear 3 slides down to its second position, the lower spring 6 gradually contracts and obtains an elastic force to restore the lower gear 3.
In a preferred embodiment, the distance the upper gear 2 is moved from its first position P1 to its second position P2 is equal to the wall thickness of the upper gear 2, and the distance the lower gear 3 is moved from its second position Q2 to its first position Q1 is equal to the wall thickness of the lower gear 3. Specifically, in the present embodiment, the first position P1 of the upper gear 2 is a position when it is engaged with the first force-receiving moving component, and the second position P2 of the upper gear 2 is a position when it is just disengaged from the first force-receiving moving component; the first position Q1 of the lower gear 3 is the position where it is just disengaged from the second force-receiving movement, and the second position Q2 of the lower gear 3 is the position where it is engaged with the second force-receiving movement component.
In other embodiments, the upper spring may be replaced by other elastic or non-elastic members to realize the connection of the upper gear and the lower gear; the lower spring may be replaced with other elastic members capable of providing elastic force.
In an optional embodiment, the axial screw 4 is composed of an upper axial screw 401 and a lower axial screw 402, and the top of the upper axial screw 401 is provided with a gear set limiting cover plate 102 which can prevent the gear from sliding out of the axial screw 4; the bottom of the lower axial screw 402 is provided with a gear set support ring 103 for limiting the lowest position of the lower gear 3 moving downwards, and simultaneously, the lower gear 3 can stably rotate at the lowest position after sliding downwards to the right position, so that power transmission is better performed.
