本实施例的抽屉组件100包括抽屉本体110、容置抽屉本体110的外框120、第一传动件130和转向件140。抽屉本体110配置为可受操作地被向前拉出于外框120或被向后推入外框120，以打开或关闭抽屉本体110，方便用户进行存取物品的操作。The drawer assembly 100 of this embodiment includes a drawer body 110, an outer frame 120 accommodating the drawer body 110, a first transmission member 130 and a steering 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 the operation of accessing items by the user.
第一传动件130配置为在抽屉本体110受到向前拉力或向后推力时，发生运动，并带动转向件140发生转动，也即是说，当抽屉本体110在由推入转为拉出或由拉出转为推入时，抽屉本体110会受到向前的拉力或向后的推力，该作用力会直接或间接地传递给第一传动件130，使得第一传动件130运动。The first transmission member 130 is configured to move when the drawer body 110 receives a forward pulling force or a backward pushing force, and drives the steering member 140 to rotate, that is, when the drawer body 110 is turned from being pushed in to pulled out or When the drawer body 110 is turned from being pulled out to being pushed in, the drawer body 110 will receive a forward pulling force or a backward pushing force, and the force will be directly or indirectly transmitted to the first transmission member 130 to cause the first transmission member 130 to move.
第一传动件130的运动可带动转向件140发生转动，而转向件140配置为在其转动时，可带动抽屉本体110同步转动至由后至前呈向下倾斜或由前至后呈向下倾斜，以便于抽屉本体110被向前拉出或向后推入。也即是说，当抽屉本体110在由推入转为拉出受到向前的拉力时，第一传动件130的运动带动转向件140转动，转向件140带动抽屉本体110同步转动至由后至前呈向下倾斜，当抽屉本体110由拉出转为推入受到向后的推力时，第一传动件130的运动带动转向件140转动，转向件140带动抽屉本体110同步转动至由前至后呈向下倾斜，从而在抽屉本体110被向前拉出或向后推入时，均可依靠其重力作用向前自由滑出或向后自由滑入，使得抽屉本体110的抽拉更加容易。The movement of the first transmission member 130 can drive the steering member 140 to rotate, and the steering member 140 is configured to drive the drawer body 110 to rotate synchronously to tilt downward from back to front or to be downward from front to back when it is rotated. Tilt so that the drawer body 110 is pulled out forward or pushed in backward. That is to say, when the drawer body 110 receives a forward pulling force from being pushed in to pulled out, the movement of the first transmission member 130 drives the steering member 140 to rotate, and the steering member 140 drives the drawer body 110 to rotate synchronously from back to back. The front is inclined downwards. When the drawer body 110 is pushed back from being pulled out to be pushed in, the movement of the first transmission member 130 drives the steering member 140 to rotate, and the steering member 140 drives the drawer body 110 to rotate synchronously from front to The rear is inclined downwards, so that when the drawer body 110 is pulled forward or pushed in, it can be freely slid forward or backward freely depending on its gravity, making the drawer body 110 easier to pull .
抽屉本体110被向前拉出过程中，为避免当停止施力时抽屉本体110向后滑动，或者，抽屉本体110被向后推入过程中，为避免当停止施力时抽屉本体110向前滑动，本实施例还增设了避免上述问题的锁止机构。When the drawer body 110 is pulled forward, in order to prevent the drawer body 110 from sliding backward when the force is stopped, or when the drawer body 110 is pushed in backward, in order to prevent the drawer body 110 from moving forward when the force is stopped. Sliding, this embodiment also adds a locking mechanism to avoid the above-mentioned problems.
具体地，抽屉本体110的至少一个侧壁外侧形成有止挡部111，为便于下述描述，此处将止挡部111所在的抽屉本体110的侧壁记为抽屉本体110的配合侧壁，显然，抽屉本体110还具有前壁和后壁，抽屉本体110的两个侧壁与前壁、后壁连接构成具有物品存放空间的抽屉本体110。Specifically, a stop portion 111 is formed on the outer side of at least one side wall of the drawer body 110. For the convenience of the following description, the side wall of the drawer body 110 where the stop portion 111 is located is denoted as the mating side wall of the drawer body 110. Obviously, the drawer body 110 also has a front wall and a rear wall, and the 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.
抽屉组件100还包括锁止件150和与第一传动件130传动连接的第二传动件160，锁止件150与止挡部111配合为在抽屉被向前拉出过程中，对抽屉的向后推入进行锁止，并配合为在抽屉被向后推入过程中，对抽屉本体110的向前拉出进行锁止。如此利用锁止件150与止挡部111的配合保证了抽屉被拉出或被推入过程中，当停止施力时可稳定停留在当前位置，无需为了保持抽屉本体110的当前位置而使得用户需要一直对抽屉本体110施力，方便用户存取物品。The drawer assembly 100 further includes a locking member 150 and a second transmission member 160 in transmission connection with the first transmission member 130. The locking member 150 cooperates with the stop portion 111 to face the drawer when the drawer is pulled out. The backward push is used for locking, and it cooperates to lock the drawer body 110 from being pulled forward when the drawer is pushed backward. In this way, the cooperation of the locking member 150 and the stopper 111 ensures that the drawer can stay in the current position stably when the force is stopped during the process of being pulled out or pushed in, without requiring the user to maintain the current position of the drawer body 110. It is necessary to always apply force to the drawer body 110 to facilitate the user to access items.
抽屉本体110在由推入转为拉出，受到向前拉力时或由拉出转为推入，受到向后推力时，配置为将作用力通过锁止件150与第二传动件160传递至第一传动件130，以使得第一传动件130发生运动，也即是说，由于锁止件150的锁止作用，抽屉本体110在由推入转为拉出，受到向前拉力时或由拉出转为推入，受到向后推力时，不会发生移动，而是将作用力通过锁止件150和第二传动件160传递至第一传动件130，使得第一传动件130运动。如前所述，第一传动件130的运动带动转向件140发生转动，转向件140在其转动时带动抽屉本体110同步转动至由后至前呈向下倾斜或由前至后呈向下倾斜。When the drawer body 110 is turned from pushing in to pulling out, when receiving a forward pulling force or turning from pulling out to pushing in, when receiving a backward pushing force, the drawer body 110 is configured to transmit the force through the locking member 150 and the second transmission member 160 to The first transmission member 130 makes the first transmission member 130 move, that is to say, due to the locking effect of the locking member 150, the drawer body 110 is turned from being pushed in to pulled out, or when it receives a forward pulling force. Pulling out is turned into pushing in. When receiving a backward thrust, it does not move, but transmits the force to the first transmission member 130 through the locking member 150 and the second transmission member 160, so that the first transmission member 130 moves. As mentioned above, the movement of the first transmission member 130 drives the steering member 140 to rotate. When the steering member 140 rotates, it drives the drawer body 110 to rotate synchronously until it tilts downward from back to front or from front to back. .
同时，第一传动件130的运动还带动第二传动件160运动，第二传动件160的运动带动锁止件150运动，锁止件150的运动以及前述抽屉本体110的转动，解除锁止，从而对抽屉本体110的向前拉出进行解锁或对抽屉本体110的向后推入进行解锁。也即是说，抽屉本体110由推入转为拉出，受到向前拉力时，锁止件150的运动以及抽屉本体110的转动对抽屉本体110的向前拉出进行解锁，使得抽屉本体110可被向前拉出，抽屉本体110由拉出转为推入，受到向后推力时，锁止件150的运动以及抽屉本体110的转动对抽屉本体110的向后推入进行解锁，使得抽屉本体110可被向后推入。At the same time, the movement of the first transmission member 130 also drives the movement of the second transmission member 160, and the movement of the second transmission member 160 drives the movement of the locking member 150. The movement of the locking member 150 and the rotation of the aforementioned drawer body 110 release the lock. Thus, the drawer body 110 is pulled forward to unlock or the drawer body 110 is pushed in backward to unlock. In other words, the drawer body 110 is turned from being pushed in to being pulled out. When receiving a forward pulling force, the movement of the locking member 150 and the rotation of the drawer body 110 unlock the drawer body 110 from being pulled forward, so that the drawer body 110 is pulled out. It can be pulled forward, and the drawer body 110 is turned from being pulled out to being pushed in. When receiving a backward pushing force, the movement of the locking member 150 and the rotation of the drawer body 110 unlock the drawer body 110 from pushing it back in, so that the drawer The body 110 may be pushed in backward.
该实施例中，通过增设锁止件150和第二传动件160，在抽屉本体110被向前拉出过程中，对抽屉本体110的向后推入进行锁止，在抽屉本体110被向后推入过程中，对抽屉本体110的向前拉出进行锁止，使得抽屉本体110在被拉出或被推入过程中，可稳定停留；并在抽屉本体110由推入转为拉出，受到向前拉力时，或者，由拉出转为推入，受到向后推力时，由于锁止件150的锁止，作用力会传递至第一传动件130，使得第一传动件130运动，第一传动件130带动第二传动件160运动，使得第二传动件160带动锁止件150运动，同时，第一传动件130带动转向件140转动，转向件140带动抽屉本体110同步转动至由后至前呈向下倾斜或由前至后呈向下倾斜，从而完成抽屉本体110角度的转换和锁止件150的解锁，实抽屉本体110由推入状态转为拉出状态，或者，由拉出状态转为推入状态，保证抽屉本体110的顺畅推拉。In this embodiment, by adding a locking member 150 and a second transmission member 160, the drawer body 110 is locked when the drawer body 110 is pulled forward, and the drawer body 110 is pushed backward.
