Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of household hardware fittings, specifically a kind of electric reset pop-up door opener. BACKGROUND

[0002] In modern furniture design, in order to improve user experience, cabinet door pressing rebounder is widely used in the opening and closing of handleless cabinet door. This device usually triggers the built-in mechanical elastic device or spring mechanism by pressing the cabinet door, so as to push the cabinet door to pop up, realizing convenient and fast operation. However, the cabinet door pressing rebounder in the prior art has some obvious defects and inconvenience in use, especially in the operation problem when the cabinet door is closed.

[0003] The cabinet door pressing rebounder on the market at present mainly relies on spring mechanism to provide elastic force, so that the cabinet door pops up after being pressed. However, when the user needs to close the cabinet door, the user needs to press the cabinet door again to compress the spring or related structure of the pressing rebounder back to the initial state, in order to complete the reset and prepare for the next pressing and popping operation. If the user does not perform this pressing operation, the rebounder will not reset, resulting in the cabinet door being unable to close completely. This design has the following obvious defects in actual use:

[0043] In one of the embodiments, the electric mechanism includes a driving motor 8 and a driving gear set 81 driven by the driving motor 8, the driving gear set 81 is connected with a driven gear set 82 through a clutch gear 9, the driven gear set 82 is engaged with a swing arm gear 42 arranged on the swing arm 4; the power of the driving motor 8 is transmitted to the swing arm 4 through the driving gear set 81, the clutch gear 9, the driven gear set 82 and the swing arm gear 42 to drive the swing arm 4 to rotate and reset.

[0044] In one of the embodiments, the clutch gear 9 is connected with a clutch shaft 91, the clutch shaft 91 slides in a guide sliding groove 93 on a clutch frame 92 to realize the engagement or separation of the clutch gear 9 with the driving gear set 81 and the driven gear set 82.

[0045] In one of the embodiments, the clutch frame 92 is installed between the driving gear set 81 and the driven gear set 82, the guide sliding groove 93 is arranged in a circular arc shape, the center of the guide sliding groove 93 is arranged concentrically with the driving gear set 81.

[0049] In one of the embodiments: the top of the swing arm 4 is provided with a guide wheel 44, the outer contour of the guide wheel 44 protrudes from the outer side of the swing arm 4.

[0050] Working principle: after the cabinet door is opened: the swing arm 4 is outside the installation area, the driving motor drives the driving gear set to rotate clockwise, thereby pushing the clutch gear to the right limit position of the guide chute, thereby pushing the clutch gear to engage with the driven gear set, realizing the power transmission from the driving gear set, the clutch gear set, and the driven gear set to the swing arm gear 42. Under the driving of the electric mechanism, the swing arm 4 rotates around the hinge point and gradually retracts into the installation area 3. During the retraction process, the power of the swing arm 4 is transmitted to the elastic device, so that it can store elastic force again and be ready for the next opening action.

[0051] At the same time, the circulation lock hook 6 is hung with the circulation lock groove 5, and then the driving motor drives the driving gear set to rotate counterclockwise, thereby pushing the clutch gear to the left limit position of the guide chute, pushing the clutch gear to disengage with the driven gear set. Cut off the power connection between the gear sets, and the swing arm will hang the circulation lock hook 6 with the circulation lock groove 5 under the action of the elastic device.

[0052] At this time, when the user closes the cabinet door, since the swing arm has been retracted into the installation area, the user does not need to press the lock when closing the cabinet door, and the cabinet door can be closed under the self-resetting action of the hinge.

[0053] When the user needs to open the cabinet door, press the cabinet door inward, the cabinet door pushes the swing arm to retract a certain stroke, the swing arm drives the circulation lock groove 5 to move relative to the circulation lock hook 6, so that the circulation lock hook 6 and the circulation lock groove 5 are separated, the swing arm loses the locking force at this time, the elastic device releases the elastic force of the torsion spring 7 or the tension spring, and the swing arm 4 swings outward of the cabinet door around the hinge point. The swing arm 4 is pushed out of the avoidance slot 31 through the front end, and the cabinet door is pushed open. The design of the guide wheel 44 ensures that the swing arm pops out smoothly, reducing friction and noise. It needs to be emphasized that since the clutch gear has been separated, the power will not be transmitted to the driving motor 8 in the opposite direction when the swing arm is opened, so that the swing arm opens more smoothly and stably.

[0054] When the cabinet door is opened, the user can manually push the cabinet door to open to the maximum state through the open gap. At the same time, the electric mechanism automatically drives the swing arm to reset, and the cycle is repeated.

[0055] The electric reset process is automatically completed without the user applying additional pressing force, significantly improving the user experience.

[0056] Among them, the need to highlight is: the door opener can also be matched with smart home, or external door button, the user sends the door opening signal to it through intelligent control or door button, drive motor 8 action, reset the swing arm again, so that the swing arm inwards swing, so that the cycle lock hook 6 and from the cycle lock groove 5 from the separation. Then drive motor reverse, drive clutch gear separation, swing arm lose locking force at this time, the elastic device torsional spring 7 or the elastic force of the release of the swing arm 4 around the hinge point to the outside of the cabinet door swing. Swing arm 4 through the front end from the avoidance slot 31 pop, push the cabinet door to automatically open, so as to realize the automatic pop of the cabinet door.

[0057] Compared with the prior art, the elastic device, the electric motor, the gear transmission system and the locking mechanism are combined innovatively in the case, the automatic pop of the cabinet door and the electric reset are realized. The core advantage is that the user can complete the reset of the rebounder without additional pressing the cabinet door. This function effectively solves the problem of manual reset of the traditional pressing rebounder, the operation is more simple, the user experience is significantly improved, so it can be widely used.

[0058] The basic principle and main features of the utility model and the advantages of the utility model are shown and described. The skilled in the art should understand that the utility model is not limited by the above examples, the above examples and the description in the specification are only to illustrate the principle of the utility model, without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, these changes and improvements all fall into the scope of the claimed utility model.
