Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
The invention provides a locking device for a cover body, which comprises a rotating shaft part, a supporting part and an anti-rotating bracket 1, wherein: the rotating shaft part comprises a shaft rod 2, a ratchet wheel 3 and a pawl 4 matched with the ratchet wheel 3, the shaft rod 2 is rotatably arranged on the supporting part, the ratchet wheel 3 is fixedly connected with the shaft rod 2, the pawl 4 is rotatably arranged on the supporting part so that the pawl 4 can be switched between an engagement position engaged with the ratchet wheel 3 and a disengagement position disengaged from the ratchet wheel 3, and in the engagement position, the pawl 4 can only rotate around the axis of the shaft rod 2 along a first direction; the supporting portion is used for being fixedly mounted on a cover body 60 so as to rotate together with the cover body 60, the cover body 60 can rotate around the axis of the shaft rod 2 relative to a workbench 70 to be switched between an opening state and a closing state, and the cover body 60 rotates around the first direction when being switched from the opening state to the closing state; the anti-rotation bracket 1 is fixedly connected to the shaft 2 and is used for being fixed to the workbench 70.
As shown in fig. 1 and 6, with the locking device for a cover provided by the present application, the anti-rotation bracket 1 of the locking device is fixedly mounted on the workbench 70 of the laundry device, and the support part is fixedly mounted on the cover 60, and since the shaft rod 2 is rotatably mounted on the support part, the support part and the cover can rotate relative to the shaft rod. When the pawl 4 is in the disengaged position, the rotation of the cover 60 is not restricted, and the cover 60 can rotate relative to the table 70 of the laundry appliance, i.e., the cover 60 can freely switch between the open state and the closed state; when the pawl 4 is in the engaged position, the tooth profile of the ratchet 3 is set to be able to rotate only in a first direction about the axis of the shaft 2 based on the characteristics of the ratchet structure, and when the cover 60 is in the closed state, the cover 60 cannot rotate in a second direction opposite to the first direction while the cover 60 needs to rotate in the second direction when shifting from the closed state to the open state, so that the cover 60 in the closed state cannot be opened.
In order to enable the transition of the pawl 4 between the disengaged position and the engaged position, the locking means may comprise a drive portion and a first resilient member 11. Wherein the first elastic element 11 connects the pawl 4 and the support portion, and the first elastic element 11 is arranged to keep the pawl 4 in the disengaged position in a natural state; the driving part is mounted to the support part and comprises a driver 5, the driving part is capable of driving the driver 5 to switch between a first position and a second position, and the driver 5 is capable of being positioned in the first position, the driver 5 is in contact with the pawl 4 so that the pawl 4 is kept in the engaged position; when the driver 5 is in the second position, the driver 5 and the pawl 4 are disengaged, in which the pawl 4 is held in the disengaged position by the first resilient member 11.
When the laundry device requires the cover body 60 to be stably maintained in the closed state during the spin-drying operation or the like, the rotation of the cover body 60 in the second direction can be restricted by positioning the driving member 5 in the first position so that the pawl member 4 is maintained in the engaged position; when the process is finished and the cover needs to be opened, the driving piece is moved to the second position, the pawl piece 4 can be kept at the disengaging position under the action of the first elastic piece 11, and the cover body 60 can be freely opened and closed.
For the top-opening type washing machine, when the cover 60 is switched from the open state to the closed state, since the cover 60 has a relatively large mass, the cover 60 is easily and rapidly dropped on the table 70 by gravity, which easily causes damage to related components and is inconvenient for the user to use daily.
In order to improve this situation, preferably, the support portion includes a main housing 6, the shaft rod 2 is rotatably disposed in the main housing 6 along a length direction of the main housing 6, the rotation shaft portion includes a first damping wheel 31, a second damping wheel 32 and a second elastic member 12 which are sequentially mounted on the shaft rod 2 along the length direction of the main housing 6, the first damping wheel 31, the second damping wheel 32 and the second elastic member 12 are all located in the main housing 6, the ratchet wheel 3 is disposed at an end portion of the shaft rod 2 and the second elastic member 12 is compressed between the ratchet wheel 3 and the second damping wheel 32, the first damping wheel 31 is fixedly connected to the shaft rod 2, the second damping wheel 32 is sleeved on the shaft rod 2, an outer wall surface of the second damping wheel 32 and an inner wall surface of the main housing 6 are provided with anti-rotation structures which cooperate with each other to prevent the second damping wheel 32 from rotating relative to the main housing 6, the rotation preventing structure is configured to enable the second damping wheel 32 to move relative to the shaft 2 and the main housing 6 along the axial direction of the shaft 2, and the end surfaces of the first damping wheel 31 and the second damping wheel 32 facing each other include mutually matched inclined surfaces, so that when the shaft 2 rotates along the first direction, the second damping wheel 32 gradually moves away from the first damping wheel 31, and the second elastic member 12 is configured to enable the first damping wheel 31 to abut against the second cover 22 in a natural state, and the first damping wheel 31 and the second damping wheel 32 are at least kept at a position where the first damping wheel 31 and the second damping wheel 32 are in contact. Wherein the second elastic member 12 is configured to maintain the first damper wheel 31 and the second damper wheel 32 at a position where the inclined surface of the first damper wheel 31 and the inclined surface of the second damper wheel 32 are completely attached in a natural state.
As shown in fig. 2, the shaft rod 2 is rotatably disposed in the main housing 6 along the length direction of the main housing 6, and the first damping wheel 31, the second damping wheel 32, the second elastic member 12 and the ratchet 3 are disposed on the shaft rod 2 along the direction from the second end to the first end of the main housing 6, wherein the first damping wheel 31 can be integrally molded with the shaft rod 2, and the outer diameter of the first damping wheel is larger than the diameter of the through hole of the main housing 6 at the second end, so that the first damping wheel abuts against the second end of the main housing 6, and the ratchet 3 abuts against the first end of the main housing 6, so that the shaft rod 2 can only rotate relative to the main housing 6 and can not move in the main housing 6 along the axial direction.
Since the second elastic member 12 is disposed between the ratchet wheel 3 and the second damping wheel 32, the ratchet wheel 3 is fixedly connected to the end of the shaft 2 and cannot move along the axial direction of the shaft 2, and the second damping wheel 32 can only move along the axial direction of the shaft 2 relative to the main housing 6 due to the rotation prevention structure formed between the second damping wheel 32 and the main housing 6, so that the second damping wheel 32 and the second elastic member 12 can interact with each other, specifically, referring to the structure of fig. 4, when the second elastic member 12 in a natural state makes the inclined surface of the second damping wheel 32 completely fit with the inclined surface of the first damping wheel 31, when the cover 60 moves along the first direction when switching from the open state to the closed state, the second damping wheel 32 follows the cover 60 and also moves along the first direction, since the end surfaces of the first damping wheel 31 and the second damping wheel 32 facing each other include the mutually matched inclined surfaces, during the rotation of the second damping wheel 32, the second damper wheel 32 is further away from the first damper wheel 31 along the axial direction of the shaft 2, and the second damper wheel 32 is gradually away from the first damper wheel 31 against the elastic force of the second elastic member 12 until the inclined surface of the second damper wheel 32 and the inclined surface of the first damper wheel 31 are disengaged from each other.
Fig. 5 is a schematic diagram illustrating the inclined surface of the second damping wheel 32 and the inclined surface of the first damping wheel 31 being disengaged from each other, and at this time, even if the cover 60 continues to move in the first direction so that the second damping wheel 32 continues to move in the first direction, the second damping wheel 32 cannot continue to compress the second elastic member 12 because the inclined surface of the first damping wheel 31 and the inclined surface of the second damping wheel 32 cannot interact with each other any more.
Therefore, when the cover 60 moves in the first direction, the second elastic member 12 is gradually compressed to generate an increasing elastic force, the cover 60 must overcome the elastic force of the second elastic member 12 to move to the closed state, and the user must continuously apply a force to close the cover 60, so as to prevent the cover 60 from being damaged due to collision with the workbench 70 caused by rapid closing under the action of gravity.
In practical application, the locking device provided by the application can be arranged such that the first damping wheel 31 and the second damping wheel 32 are completely attached to each other when the cover body 60 is completely opened, so that the damping effect of the second elastic member 12 can be applied to the whole cover closing process of the cover body 60, and the first damping wheel 31 and the second damping wheel 32 can be separated from each other only in a closed state of the cover body 60, thereby ensuring that the damping wheel generated by the second elastic member 12 is gradually increased in the cover closing process.
The anti-rotation structure may be in an appropriate form, and preferably, one of the inner wall surface of the main housing 6 and the outer wall surface of the second damping wheel 32 is provided with a rib along the length direction of the main housing 6, and the other is provided with a groove matched with the rib, and the rib and the groove are engaged with each other to form the anti-rotation structure together.
Fig. 4 and 5 show an embodiment in which the outer wall surface of the second damping wheel 32 is provided with a rib along the length direction of the main housing 6, and accordingly, the inner wall surface of the main housing 6 is provided with a groove along the length direction of the main housing 6, and the second damping wheel 32 can be driven to rotate together by the matching structure of the rib and the groove when the main housing 6 rotates, and by the matching structure, when the second damping wheel 32 rotates together with the main housing 6 relative to the shaft 2, the second damping wheel 32 also generates axial movement relative to the shaft 2 by the movement of the rib in the groove during the rotation process.
Preferably, the supporting portion includes a main housing 6 and a first cover 21 located at a first end of the main housing 6 in a length direction, a detent shaft rod 7 is disposed on the first cover 21, the detent member 4 is sleeved on the detent shaft rod 7, the first elastic member 11 is connected to the main housing 6 and the detent member 4, the driving portion includes a motor 8 for driving the driving member 5, and the driving member 5 is a cam.

As shown in fig. 2 and 3, the motor 8 may be fixedly disposed on the main housing 6 through a bolt connection, the motor 8 may drive the cam to switch between a first position and a second position, when the cam is in the first position, the cam is in contact with the protruding rod 42 to keep the pawl 4 at the engaged position, and at this time, the ratchet 3 may only rotate in the first direction, and when the ratchet 3 rotates in the second direction opposite to the first direction, the ratchet 3 may push the pawl 4 to make the pawl 4 rotate around the pawl shaft 7 correspondingly, and since the protruding rod 42 is in contact with the cam to be stopped by the cam at this time, the protruding rod 42 may not rotate correspondingly, so that the ratchet 3 may not rotate in the second direction. The driving member 5 is not limited to a cam, and may be an eccentric wheel, an eccentric shaft, or the like.
