Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of home hardware, in particular to a drawer synchronous rebound device and a drawer thereof. BACKGROUND

[0002] At present, the drawers in the home can be generally divided into two types: pull-out type and press-rebound type. The press-rebound type is more popular among users due to its convenient and quick automatic ejection function and the function of preventing children from opening the drawer.

[0003] However, the length of the traditional press-rebound device is large, and it is generally installed between the inner wall of the cabinet and the side of the drawer, or between the fixed rail and the movable rail of the drawer slide rail. This form occupies a large space inside the cabinet and is inconvenient to install. In order to solve this problem, the patent with the patent application number 202020266223.3 discloses an external hanging type press-swing rebound device, which includes a connecting mechanism and a rebound mechanism. The rebound mechanism includes a mounting seat, a rebound limiting seat, a rotating arm, a shaft, an elastic element and a sliding positioning needle. The rebound limiting seat is fixed on the mounting seat, the rotating arm is rotatably installed on the mounting seat through the shaft, and the elastic element is arranged between the mounting seat and the rotating arm. One end of the rotating arm is provided with a striker slot, and the connecting mechanism has a striker. The two rebound mechanisms on the sides are connected and move synchronously through a synchronization piece. This patent uses the rotation of the rotating arm to lock and unlock the rebound to realize the connection or rebound between the movable part and the fixed part, and solves the problem of inconsistent synchronization on both sides. However, this patent still has defects. The striker of the device needs to move linearly along the guide rail before contacting the rotating arm. In actual working conditions, the strikers on both sides have already generated a front-back position difference before contacting the rotating arm. The synchronization piece cannot synchronize the strikers on both sides back to the same position, and the structure is prone to damage after a period of use. There are also some press-rebound devices in the form of gear and rack. When the rebound device is hit by the striker, the gear and rack may have a misaligned tooth due to the instantaneous displacement, causing synchronization failure. SUMMARY

[0037] As shown in Figure 1 , Figure 2 is a schematic view of the drawer synchronous rebound device of the present application, as shown in Figure 3 is an exploded view of the drawer synchronous rebound device of the present application, as shown in Figure 4 is a schematic view of the drawer mechanism used in the present application, setting the direction of the drawer pushing inward as the first direction, from Figures 1-4 It can be seen that the drawer synchronous rebound device comprises a rotating member 1, a connecting member 2, a sliding member 3, a reset device 4 and a synchronous member 6, as shown in Figure 5As shown, the rotating component 1 includes a movable end 11 and an output shaft 12. The movable end 11 rotates around the rotation axis of the rotating component 1. The output shaft 12 is coaxial with the rotating component 1 and rotates synchronously. One end of the connecting member 2 is rotatably connected to the movable end 11 of the rotating component 1, and the other end of the connecting member 2 is rotatably connected to the sliding member 3. The synchronizing member 6 is connected to the output shaft 12 and rotates synchronously. Figure 1 , Figure 2 As shown, the slider 3 includes an initial position and a final position. The slider 3 is limited in a first direction and reciprocates between the initial position and the final position. The rotating member 1, the connecting member 2, and the slider 3 together constitute a crank-slider mechanism. The reset device 4 is connected to the slider 3 and has a tendency to move the slider 3 from the final position to the initial position. Figure 4 As shown, the drawer used in this invention also reciprocates in the first direction. The drawer also includes a pusher 7 that moves synchronously with it. When the pusher 7 moves in the first direction, the pusher 7 and the slider 3 are connected and move synchronously in their initial positions. When the pusher 7 moves away from the first direction, the pusher 7 and the slider 3 are separated in their initial positions.

[0038] In one embodiment of the drawer synchronous rebound device described in this invention, the pushing member 7 is a pin installed at the end of the upper guide rail of the drawer. When one side of the drawer is pushed inward, the upper guide rail on one side of the drawer moves in a first direction. During the movement, the pin at the end of the upper guide rail contacts the sliding member 3 in its initial position, and the pin pushes the sliding member 3 to move together in the first direction. Since the rotating member 1, the connecting member 2, and the sliding member 3 together constitute a crank-slider mechanism, when the sliding member 3 moves in the first direction, the thrust in the first direction on the sliding member 3 is converted into torque that causes the rotating member 1 to rotate through the transmission action of the connecting member 2. And because the output shaft 12 moves synchronously with the rotating member 1, the output shaft 12 drives the synchronizing member 6 to rotate, thereby transmitting the torque to the drawer synchronous rebound device on the other side, causing the sliding member there to also move in the first direction. In this way, the synchronous energy storage effect of the synchronous rebound devices on both sides of the drawer is achieved. When the drawer stops being pushed in the first direction, the reset device 4 provides a force to the slider 3 in the opposite direction. On the one hand, this force is transmitted to the synchronous rebound device on the other side through the crank-slider mechanism, so that the synchronous rebound devices on both sides move synchronously. On the other hand, the slider 3 drives the pusher 7 to move in the opposite direction. The synchronous rebound devices on both sides work together to push the drawer out in the opposite direction.

[0039] Compared with the prior art, the drawer pushing piece of the present application is limited in the first direction when moving in the first direction, and the pushing piece 7 is connected with the sliding piece 3, so that the pushing piece 7 is also limited in the first direction during movement, avoiding disturbance of the pushing piece 7 during drawer pushing, and the position of the pushing piece 7 during movement is as stable as possible, which reduces the possibility of front and back dislocation of the pushing piece 7 on both sides of the drawer, so that the drawer synchronous rebound device can maintain a good use state for a long time. Moreover, the synchronous rebound device of the present application uses a crank slider mechanism instead of a gear and rack structure, so that the gear teeth are not dislocated when impacted, and the reliability of the synchronous rebound device of the present application is relatively higher.

[0040] Specifically, as shown in Figure 3 one embodiment, the synchronous rebound device of the present application further comprises a housing 5, the housing 5 is provided with a sliding groove, the sliding groove is parallel to the first direction, and the sliding piece 3 can slide along the sliding groove.

[0041] Preferably, in one embodiment, in order to further improve the stability of the pushing piece 7, the sliding piece 3 of the present application comprises a first sliding piece 31 and a second sliding piece 32, the second sliding piece 32 is connected with the first sliding piece 31, the connecting piece 2 is rotationally connected with the first sliding piece 31, and the second sliding piece 32 is connected with the pushing piece 7. In this way, since the sliding piece 3 is limited by the sliding groove, the pushing piece 7 will always be limited by the second sliding piece 32 during movement.

[0042] Further, as shown in Figure 6 one embodiment, the second sliding piece 32 is pivotally installed on the first sliding piece 31, the second sliding piece 32 is provided with a pushing piece slot 321, the second sliding piece 32 has a first state and a second state during rotation, when the sliding piece 3 is in the initial position, the second sliding piece 32 is in the first state, the opening of the pushing piece slot 321 is open to the first direction, and the pushing piece 7 moving along the first direction can be inserted into the pushing piece slot 321 of the second sliding piece 32, when the sliding piece 3 moves from the initial position to the terminal position, the second sliding piece 32 is in the second state, the opening of the pushing piece slot 321 is not open to the first direction, and the pushing piece 7 is fixed in the pushing piece slot 321. In this way, the synchronous pushing device of the present application can ensure the stability of the pushing piece 7 on both sides during synchronous movement with the sliding piece 3, and can also smoothly separate the pushing piece 7 from the sliding piece 3 during asynchronous movement, thereby ensuring the flexibility of drawer pushing and pulling. For example, when the pushing piece 7 is a pin, the pushing piece slot 321 is a pin slot.

[0043] Specifically, as shown in Figure 6 The chute includes a first chute 51 and a second chute 52, the first sliding member 31 is provided with a first sliding block, the second sliding member 32 is provided with a second sliding block, the first sliding block can slide in the first chute 51, the second sliding block can slide in the second chute 52, the first chute 51 is parallel to the first direction, the second chute 52 includes a straight section 521 and a curved section 522, when the second sliding block slides in the straight section 51, the second sliding member 32 is in the second state, when the second sliding block slides in the curved section 52, the second sliding member 32 is in the first state.

[0044] As shown in Figure 7 It is a schematic view of the drawer synchronous rebound device in the drawer, as shown in Figure 8 It is a schematic view of the connection relationship between the drawer synchronous rebound device and the pusher 7, as shown in Figure 9 It is Figure 8 An enlarged view of part A in the figure, specifically showing the position relationship when the pusher 7 is connected with the sliding member 3. In this embodiment, the drawer synchronous rebound device is fixed between the two side rails, Figure 7The right side guide rail and the right side drawer synchronous rebound device are shown. The connecting piece 7 is a pin arranged on the upper guide rail, the second sliding piece 32 extends out of the shell 5, and the pusher slot 321 on the second sliding piece 32 is always higher than the shell 5. When the sliding piece 3 is in the initial position, the second sliding piece 32 is in the curved section 522 of the second sliding groove 52, and the second sliding piece 32 is in the first state, at this time, the opening of the pusher slot 321 is open to the first direction. The pin moves along the first direction from above the shell 5, enters the second sliding piece 32 from the opening of the pusher slot 321, and is at the bottom of the pusher slot 321. With the continuous movement of the drawer along the first direction, the pin pushes the second sliding piece 32 and the first sliding piece 31 to move from the initial position to the terminal position, in the process, the second sliding piece 32 enters the straight section 521 from the curved section 522 of the second sliding groove 52, and the second sliding piece 32 rotates around the rotating connection with the first sliding piece 31, changes from the first state to the second state, and due to the rotating limiting structure arranged on the first sliding piece 31, the second sliding piece 32 remains in the second state. The pin moving along the first direction cannot leave the pusher slot 321 of the second sliding piece 32 in the second state, thereby driving the sliding piece 3 to move to the terminal position. When the sliding piece 3 moves from the terminal position to the initial position under the action of the reset device 4, the second sliding piece 32 moves along the second sliding groove from the straight section 521 to the curved section 522, and also changes from the second state to the first state, and the opening of the pusher slot 321 is re-opposed to the first direction. In the process, the sliding piece 3 transmits the force of the reset device 4 to the pin, so that the pin moves away from the first direction, and finally leaves the opening of the pusher slot 321, so that the drawer can be freely opened outward.

[0045] Specifically, in one embodiment, the reset device 4 is a tension spring, one end of which is fixed on the shell 5, and the other end is fixed on the sliding piece 3. When the pusher 7 pushes the sliding piece 3 to move from the initial position to the terminal position, the tension spring is stretched, and when the pusher 7 no longer pushes the sliding piece 3, the tension spring is contracted to pull the sliding piece 3 from the terminal position to the initial position.

[0046] Specifically, in one embodiment, the rotating piece 1 is provided with one of a rotating shaft or a shaft hole, and the shell 5 is provided with the other.

[0047] In order to improve the synchronization effect of the synchronous rebound device on both sides of the drawer, the synchronization piece 6 is also improved. As shown in Figure 10As shown, the synchronizer 6 comprises a synchronizer rod 61, an adapter 62 and a sleeve 63, the adapter 62 is arranged at both ends of the synchronizer rod 61, the adapter 62 is connected with the output shaft 12, the sleeve 63 is fitted on the adapter 62 in an interference fit, the output shaft 12 is fixed radially with the adapter 62, and the sleeve 63 rotates relative to the adapter 62.

[0048] Specifically, in one embodiment, as shown in Figure 11 As shown, the output shaft 12 is plate-shaped, the adapter 62 is provided with a cavity matching the profile of the output shaft 12, the cavity is provided with an opening on the side wall of the adapter 62, and the sleeve 63 is provided with a notch on the side wall thereof corresponding to the opening. In this way, the plate-shaped output shaft 12 can enter the cavity from the notch of the sleeve 63 and the opening on the side wall of the adapter 62 in sequence. Then, the sleeve 63 is rotated so that the notch of the sleeve 63 is misaligned with the opening of the adapter 62, thereby achieving radial fixation of the output shaft 12 with the adapter 62.

[0049] Further preferably, as shown in Figure 10 , Figure 11 As shown, the adapter 62 is provided with a first limiting plane, the sleeve 63 is provided with a second limiting plane corresponding to the first limiting plane, and the first limiting plane and the second limiting plane can be matched and fitted. In this way, when the first limiting plane and the second limiting plane are matched and fitted, the sleeve 63 and the adapter 62 can be guided and positioned. For example, in one embodiment, when the first limiting plane and the second limiting plane are matched and fitted, the opening and the notch are misaligned, which can improve the locking effect of the sleeve 63 and the adapter 62, and the output shaft 12 is not easy to be separated from the adapter 62; in another embodiment, when the first limiting plane and the second limiting plane are matched and fitted, the opening and the notch are aligned, which can facilitate the output shaft 12 to enter and exit the adapter 62; in yet another embodiment, the first limiting plane is a plurality of limiting planes, and the plurality of limiting planes are symmetrically arranged on both sides of the opening, and the plurality of limiting planes are symmetric about the axis center of the output shaft 12, so that the sleeve 63 can facilitate the output shaft 12 to enter and exit the adapter 62 and also facilitate the fixation of the output shaft 12 in the adapter 62.

[0050] Further preferably, as shown in Figure 12 As shown, the sleeve 63 and the adapter 62 are provided with axial fixation structures, for example, the axial fixation structures can be buckles and bosses.

[0051] In summary, the present application optimizes the structure of the drawer synchronous rebound device, minimizes the impact of shaking during drawer sliding by the crank slider structure composed of rotating parts, connecting parts and sliding parts, thereby preventing the front and back misalignment of both sides during drawer sliding, and preventing the gear structure from being misaligned due to instantaneous impact since the gear is not used. On this basis, the sliding part is optimized, so that the drawer pusher can be firmly fixed during the inward pushing process, and the synchronous rebound device on both sides can function normally. During the outward rebounding process of the drawer, the pusher is released from the fixed state, and the pusher can move freely, so that the drawer can slide freely. At the same time, the present application improves the synchronization part, which can be more conveniently, quickly and stably installed on the output shaft of the synchronous rebound device.

[0052] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.

[0053] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these are within the protection scope of the present application.
