Detailed Description
The present embodiment provides a drawer assembly 100, and the drawer assembly 100 may be a storage drawer of a household appliance, for example, a refrigerator, furniture, and the like.
The drawer assembly 100 of the present embodiment includes a drawer body 110, an outer frame 120 accommodating the drawer body 110, a first transmission member 130, and a turning member 140. The drawer body 110 is configured to be operatively pulled out of the outer frame 120 or pushed back into the outer frame 120 to open or close the drawer body 110, facilitating a user to perform an operation of accessing the articles.
The first transmission member 130 is configured to move when the drawer body 110 is pulled forward or pushed backward, and the rotation member 140 is driven to rotate, that is, when the drawer body 110 is converted from being pushed into being pulled out or from being pulled out into being pushed in, the drawer body 110 is pulled forward or pushed backward, and the acting force is directly or indirectly transmitted to the first transmission member 130, so that the first transmission member 130 moves.
The movement of the first transmission member 130 can drive the rotation member 140 to rotate, and the rotation member 140 is configured to drive the drawer body 110 to synchronously rotate to be inclined downwards from back to front or inclined downwards from front to back when rotating, so that the drawer body 110 can be pulled out forwards or pushed in backwards. That is, when the drawer body 110 is pulled out from the push-in direction, the first transmission member 130 moves to drive the turning member 140 to rotate, the turning member 140 drives the drawer body 110 to synchronously rotate to incline downwards from back to front, when the drawer body 110 is pulled out from the push-in direction, the first transmission member 130 moves to drive the turning member 140 to rotate, the turning member 140 drives the drawer body 110 to synchronously rotate to incline downwards from front to back, and therefore when the drawer body 110 is pulled out from the front or pushed back, the drawer body can freely slide out from the front or slide in from the back under the action of gravity, so that the drawer body 110 can be pulled out more easily.
In the process of pulling the drawer body 110 forward, in order to prevent the drawer body 110 from sliding backward when the force application is stopped, or in the process of pushing the drawer body 110 backward, in order to prevent the drawer body 110 from sliding forward when the force application is stopped, a locking mechanism is further added to this embodiment to avoid the above problem.
Specifically, a stopping portion 111 is formed outside at least one side wall of the drawer body 110, for convenience of the following description, a side wall of the drawer body 110 where the stopping portion 111 is located is referred to as a matching side wall of the drawer body 110, and obviously, the drawer body 110 further has a front wall and a rear wall, and two side walls of the drawer body 110 are connected with the front wall and the rear wall to form the drawer body 110 with an article storage space.
The drawer assembly 100 further comprises a locking member 150 and a second transmission member 160 in transmission connection with the first transmission member 130, wherein the locking member 150 cooperates with the stopping portion 111 to lock the backward pushing of the drawer during the process of being pulled out forwards, and cooperates to lock the forward pulling out of the drawer body 110 during the process of being pushed in backwards. Thus, the locking member 150 and the stopping portion 111 are matched to ensure that the drawer can be stably stopped at the current position when the force is stopped in the process of being pulled out or pushed in, so that the user does not need to apply force to the drawer body 110 all the time in order to keep the current position of the drawer body 110, and the user can conveniently store and take articles.
When the drawer body 110 is converted from pushing to pulling, receiving a forward pulling force, or from pulling to pushing, and receiving a backward pushing force, the drawer body is configured to transmit an acting force to the first transmission member 130 through the locking member 150 and the second transmission member 160, so as to move the first transmission member 130, that is, due to the locking effect of the locking member 150, when the drawer body 110 is converted from pushing to pulling, receiving a forward pulling force, or from pulling to pushing, receiving a backward pushing force, the drawer body does not move, but transmits an acting force to the first transmission member 130 through the locking member 150 and the second transmission member 160, so as to move the first transmission member 130. As mentioned above, the movement of the first transmission member 130 drives the rotation member 140 to rotate, and the rotation member 140 drives the drawer body 110 to synchronously rotate to be inclined downwards from back to front or inclined downwards from front to back.
Meanwhile, the movement of the first transmission member 130 also drives the second transmission member 160 to move, the movement of the second transmission member 160 drives the locking member 150 to move, the locking is released by the movement of the locking member 150 and the rotation of the drawer body 110, and therefore the drawer body 110 is pulled out forwards to be unlocked or the drawer body 110 is pushed backwards to be unlocked. That is, when the drawer body 110 is changed from pushing to pulling, and when a forward pulling force is applied, the movement of the locking member 150 and the rotation of the drawer body 110 unlock the forward pulling of the drawer body 110, so that the drawer body 110 can be pulled forward, and when the drawer body 110 is changed from pulling to pushing, when a backward pushing force is applied, the movement of the locking member 150 and the rotation of the drawer body 110 unlock the backward pushing of the drawer body 110, so that the drawer body 110 can be pushed backward.
In this embodiment, by additionally providing the locking member 150 and the second transmission member 160, the backward pushing of the drawer body 110 is locked while the drawer body 110 is being pulled out forward, and the forward pulling of the drawer body 110 is locked while the drawer body 110 is being pushed back, so that the drawer body 110 can stably stay while being pulled out or pushed in; when the drawer body 110 is pulled out from a pushing state, and a forward pulling force is applied, or the drawer body is pulled out from the pulling state to a pushing state, and a backward pushing force is applied, due to the locking of the locking member 150, an acting force is transmitted to the first transmission member 130, so that the first transmission member 130 moves, the first transmission member 130 drives the second transmission member 160 to move, so that the second transmission member 160 drives the locking member 150 to move, meanwhile, the first transmission member 130 drives the steering member 140 to rotate, the steering member 140 drives the drawer body 110 to synchronously rotate to be inclined downwards from back to front or inclined downwards from front to back, so that the angle conversion of the drawer body 110 and the unlocking of the locking member 150 are completed, the drawer body 110 is actually converted from the pushing state to the pulling state, or the pulling state is converted to the pushing state, and the smooth pushing and pulling of the drawer body 110 are ensured.
In the embodiment shown in the drawings, the locking member 150 may include a locking plate 151 and two locking racks 152 extending back and forth, the locking plate 151 being located at an outer side of the mating sidewall and an inner side of the outer frame 120, a locking groove 151a being formed at a side of the locking plate 151 facing the mating sidewall; two locking racks 152 are distributed in the locking groove 151a at intervals from top to bottom, the tooth grooves of the locking racks 152 above the locking racks 152 are recessed upwards, the tooth grooves of the locking racks 152 below the locking racks 152 are recessed downwards, the front end faces 152a of the tooth grooves of the locking racks 152 below the locking racks 152 are inclined upwards from back to front, the rear end faces 152b are inclined upwards from front to back, and the inclination angle of the front end faces 152a of the tooth grooves of the locking racks 152 relative to the vertical plane is larger than that of the rear end faces 152b relative to the vertical plane; the front end face of the tooth groove of the locking rack 152 located above is inclined downward from back to front, the rear end face is inclined downward from front to back, and the inclination angle of the rear end face of the tooth groove of the locking rack 152 with respect to the vertical plane is larger than that of the front end face thereof. That is, the teeth of the two locking racks 152 are helical teeth, the front end surface 152a of each tooth of the lower locking rack 152 has a small gradient and the rear end surface 152b has a large gradient, and the upper locking rack 152 is opposite to the lower locking rack 152, and the front end surface of each tooth of the upper locking rack 152 has a large gradient and the rear end surface has a small gradient.
And the stopping portion 111 is formed at a position adjacent to the rear side of the mating sidewall, and a lower portion of the stopping portion 111 is in contact with a tooth groove of the locking rack 152 located below or an upper portion of the stopping portion 111 is in contact with a tooth groove of the locking rack 152 located above in a process that the drawer body 110 is pulled out forward or pushed in backward. That is, during the drawer body 110 is pulled out forward, the lower portion of the stopping portion 111 contacts with the toothed groove of the locking rack 152 located below, and the upper portion of the stopping portion 111 disengages from the toothed groove of the locking rack 152 located above; in the process that the drawer body 110 is pushed backward, the upper portion of the stopper portion 111 contacts with the tooth groove of the locking rack 152 located above, and the lower portion of the stopper portion 111 disengages from the tooth groove of the locking rack 152 located below.
Because the inclination angle of the front end surface 152a of the tooth socket of the lower locking rack 152 is greater than that of the rear end surface 152b, the rear end surface 152b of the tooth socket of the lower locking rack 152 limits the stopping portion 111 in contact with the lower locking rack 152, so that the drawer body 110 is pulled out forwards, and does not slide backwards when force application is stopped, and because the inclination angle of the rear end surface of the tooth socket of the upper locking rack 152 is greater than that of the front end surface, the front end surface of the tooth socket of the upper locking rack 152 limits the stopping portion 111 in contact with the upper locking rack 152, so that the drawer body 110 is pushed backwards, and does not slide forwards when force application is stopped, so that the rear end surface 152b of the lower locking rack 152 is used for locking the backwards pushing of the drawer body 110, and the front end surface of the upper locking rack 152 is used for locking the forwards pulling out of the drawer body 110, thereby ensuring that the drawer body 110 can stay stably and does not slide backwards when being pulled out and pushed in.
In the embodiment shown in the drawings, the steering member 140 includes a steering plate 141 located outside the locking plate 151 and inside the outer frame 120, an upper side of the steering plate 141 protrudes above the locking plate 151, and a lower side of the steering plate 141 protrudes below the locking plate 151, that is, a dimension of a plate surface of the steering plate 141 in the vertical direction is larger than a dimension of a plate surface of the locking plate 151 in the vertical direction, and both the upper side and the lower side of the steering plate 141 are exposed without being covered by the locking plate 151. The upper side of the turning plate 141 is located above the drawer body 110 and is formed with an upper limit portion 142 protruding toward the matching side wall and extending forward and backward, the lower side of the turning plate 141 is formed with a lower limit portion 143 protruding toward the matching side wall and extending forward and backward, and the turning member 140 is configured to rotate the drawer body 110 synchronously by the acting force of the upper limit portion 142 and the lower limit portion 143 on the drawer body 110 when the turning member rotates, so that the turning member 140 rotates to drive the drawer body 110 to rotate synchronously, thereby realizing the angle conversion of the drawer body 110.
In some embodiments, a first roller 144 may be disposed on the front upper portion of the lower limiting portion 143, a slide rail 112 protruding above the lower limiting portion 143 toward the direction of the steering plate 141 and extending forward and backward is formed on the outer side of the matching side wall, a second roller 113 is disposed on the rear lower portion of the slide rail 112, the second roller 113 contacts the lower limiting portion 143, and the slide rail 112 contacts the first roller 144, so that the drawer body 110 can always slide along the lower limiting portion 143 during being pushed in or pulled out, thereby ensuring stable forward and backward sliding of the drawer body 110.
In the embodiment of the drawings, the first transmission member 130 and the second transmission member 160 are both gear structures, and the rotation axes of the gear structures are both parallel to the width direction of the drawer body 110.
