Description

Technical Field

[0001] The invention relates to a household hardware accessory, in particular to an electric reset spring-opening door opener. Background Art

[0002] In modern furniture design, in order to improve user experience, cabinet door push-rebound devices are widely used to open and close handleless cabinet doors. This device usually triggers a built-in mechanical elastic device or spring mechanism by pressing the cabinet door, thereby pushing the cabinet door to bounce open, achieving convenient and quick operation. However, cabinet door push-rebound devices in the prior art have some obvious defects and inconveniences in use, especially in terms of operation problems when the cabinet door is closed.

[0003] The cabinet door push-and-pull devices currently on the market mainly rely on a spring mechanism to provide elastic force, so that the cabinet door will bounce open after being pressed. However, this design requires the user to press the cabinet door again when the user needs to close the cabinet door to compress the spring or related structure of the push-and-pull device back to the initial state to complete the reset and prepare for the next push-and-pull operation. If the user does not perform this pressing operation, the rebounder will not be able to reset, resulting in the cabinet door being unable to be completely closed. This design has the following obvious defects in actual use: 1. Complex operation and poor user experience: When closing the cabinet door, the user needs to press the cabinet door hard to trigger the rebounder to reset. This additional operation not only increases the complexity of use, but also places higher requirements on the user's hand force, especially for the elderly or users with weak hand strength.

[0004] 2. Unsatisfactory closing effect: If the user fails to fully press the cabinet door to fully reset the rebounder, the cabinet door will be partially open and unable to fit the cabinet body, affecting the appearance and function of the furniture. This situation is particularly common when the user mistakenly believes that the cabinet door is closed, which can easily lead to dust entering the cabinet body or other unnecessary subsequent problems.

[0005] In order to solve the above problems, there are some improvement schemes, such as optimizing the reset effect by improving the design of the spring mechanism, or improving the smoothness of operation by adding a damping device. However, these improvement schemes still cannot fundamentally solve the problem that users need to press extra pressure to reset when closing the cabinet door, so it is necessary to make further improvements. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide an electric reset pop-up door opener with a simple structure, easy to use, and able to automatically reset through optimized design after the cabinet door pops open, without the need for the user to apply additional pressing force when closing, while ensuring that the cabinet door can be completely closed, easy to operate, and long service life.

[0007] The object of the present invention is achieved by the following method: an electric reset spring-opening door opener, which includes a bottom shell and a face mask, a mounting area is hollowed out between the bottom shell and the face mask, and the front end of the mounting area penetrates the bottom shell and the face mask to form an air-avoiding groove; A swing arm is hingedly installed in the installation area, and the swing arm pops out from the air avoidance groove to push the cabinet door to open; An elastic device is installed in the installation area, and the elastic device pushes the swing arm to always swing in the door opening direction; An electric mechanism is also installed in the installation area, the electric mechanism is connected to the swing arm, and the electric mechanism pushes the swing arm to retract and reset into the installation area; A circulating lock groove is also arranged in the swing arm, and a circulating lock hook is installed in the installation area. The circulating lock hook is hooked with or separated from the circulating lock groove to realize locking and releasing of the swing arm.

[0008] Furthermore: the elastic device is a torsion spring installed in the installation area, one supporting leg of the torsion spring is fixed in the installation area, and the other supporting leg is connected to the driving arm arranged on the swing arm. The torsion spring applies elastic force on the driving arm to push the swing arm to move in the opening direction.

[0009] Furthermore: the elastic device is a tension spring installed in the installation area, one end of the tension spring is fixed in the installation area, and the other end is connected to the driving arm arranged on the swing arm. The tension spring applies elastic force on the driving arm to push the swing arm to move in the opening direction.

[0010] Furthermore: the electric mechanism includes a driving motor and a driving gear set driven by the driving motor, the driving gear set is connected to the driven gear set through a clutch gear, and the driven gear set is meshed with a swing arm gear arranged on the swing arm; the power of the driving motor is transmitted to the swing arm through the driving gear set, the clutch gear, the driven gear set and the swing arm gear, driving the swing arm to rotate and reset.

[0011] Furthermore, the clutch gear is connected with a clutch shaft, and the clutch shaft slides in a guide slot on the clutch frame to achieve meshing or separation of the clutch gear with the driving gear set and the driven gear set.

[0012] Furthermore: the clutch frame is installed between the driving gear set and the driven gear set, the guide slide groove is arranged in an arc shape, and the center of the guide slide groove is arranged concentrically with the driving gear set.

[0013] Furthermore: the clutch frame includes a base fixed to the installation area, a gear frame is provided on the top of the base protruding upward, and the two sides of the gear frame are hollowed out to form a meshing area, the guide groove is provided at the top and bottom of the gear frame, and the clutch shaft is provided at the upper and lower ends of the protruding clutch gear and is inserted into the guide grooves at the upper and lower ends of the gear frame.

[0014] Furthermore: the circulating lock hook is arranged on the lock seat arm, the lock seat arm is provided with a mounting ring, and the mounting ring is swingably sleeved on the hinge shaft in the mounting area.

[0015] Furthermore: the circulating lock groove is arranged on the lock seat, a lock hole is arranged on the inner side surface of the swing arm, and the lock seat is installed in the lock hole.

[0016] Furthermore: a guide wheel is arranged on the top of the swing arm, and the outer contour of the guide wheel protrudes from the outer side surface of the swing arm.

[0017] The beneficial effects of the present invention are: 1. Simple structure, low production cost and improved market competitiveness.

[0018] 2. By designing the electric mechanism and the swing arm gear transmission mechanism, the swing arm can automatically pop out the cabinet door under the action of the elastic device, and the electric mechanism can realize the retraction and reset of the swing arm, without the user having to press the cabinet door additionally when closing the cabinet door to complete the reset of the rebounder. This function effectively solves the problem of the traditional pressing rebounder requiring manual reset, making the operation easier and significantly improving the user experience.

[0019] 3. The locking and releasing functions of the swing arm are realized by setting the circulating lock slot and circulating lock hook structure. When the cabinet door is closed, the circulating lock hook automatically hooks into the circulating lock slot to ensure that the swing arm remains stable after resetting, avoiding the problem that the cabinet door is not completely closed due to the swing arm not being reset, improving the fit between the cabinet door and the cabinet body, and preventing dust from entering or affecting the appearance of the cabinet door.

[0020] 4. The electric mechanism of the present invention realizes power transmission through the cooperation of the driving motor and the clutch gear, and the clutch gear can control the meshing or separation with the driving gear set or the driven gear set as needed, ensuring accurate and reliable action when it needs to be opened or reset. It avoids device failure caused by mechanical parts jamming or user misoperation, and improves the safety and reliability of the overall device.

[0021] 5. The electric reset design reduces the frequency of external force applied by the user, greatly reducing the mechanical fatigue or loss of internal elastic devices such as torsion springs, tension springs and mechanical parts. Compared with traditional press rebounders, the product life is longer and the maintenance cost is lower. BRIEF DESCRIPTION OF THE DRAWINGS

An electric reset spring-opening door opener, characterized in that: it comprises a bottom shell 1 and a face mask 2, a mounting area 3 is hollowed out between the bottom shell 1 and the face mask 2, and the front end of the mounting area 3 penetrates the bottom shell 1 and the face mask 2 to form a void groove 31; A swing arm 4 is hingedly installed in the installation area 3, and the swing arm 4 pops out from the air avoidance groove 31 to push the cabinet door to open; An elastic device is installed in the installation area 3, and the elastic device pushes the swing arm 4 to always swing in the door opening direction; An electric mechanism is also installed in the installation area 3, and the electric mechanism is connected to the swing arm 4, and the electric mechanism pushes the swing arm 4 to retract and reset into the installation area 3; The swing arm 4 is also provided with a circulation lock groove 5 , and the installation area 3 is provided with a circulation lock hook 6 , which is hooked with or separated from the circulation lock groove 5 to achieve locking and releasing of the swing arm 4 .

[0032] In one of the embodiments: the elastic device is a torsion spring 7 installed in the installation area 3, one supporting foot 71 of the torsion spring 7 is fixed in the installation area 3, and the other supporting foot 71 is connected to the driving arm 41 set on the swing arm 4. The torsion spring 7 applies elastic force on the driving arm 41 to push the swing arm 4 to move in the opening direction.

[0033] In one embodiment, the elastic device is a tension spring installed in the installation area 3, one end of the tension spring is fixed in the installation area 3, and the other end is connected to the driving arm 41 set on the swing arm 4. The tension spring applies elastic force on the driving arm 41 to push the swing arm 4 to move in the opening direction.

[0034] In one embodiment: 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 to the driven gear set 82 through the clutch gear 9, and the driven gear set 82 is meshed with the swing arm gear 42 provided 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, driving the swing arm 4 to rotate and reset.

[0035] In one embodiment, the clutch gear 9 is connected to a clutch shaft 91 , and the clutch shaft 91 slides in a guide slot 93 on a clutch frame 92 to achieve meshing or separation of the clutch gear 9 with the driving gear set 81 and the driven gear set 82 .

[0036] In one embodiment, the clutch frame 92 is installed between the driving gear set 81 and the driven gear set 82 , and the guide slot 93 is arranged in an arc shape, and the center of the guide slot 93 is arranged concentrically with the driving gear set 81 .

[0037] In one of the embodiments: the clutch frame 92 includes a base 921 fixed to the mounting area 3, the top of the base 921 protrudes upwardly to provide a gear frame 922, the two sides of the gear frame 922 are hollowed out to form a meshing area 923, the guide groove 93 is arranged at the top and bottom of the gear frame 922, the clutch shaft 91 protrudes from the upper and lower ends of the clutch gear 9, and is inserted into the guide grooves 93 at the upper and lower ends of the gear frame 922.

[0038] In one of the embodiments: the circulating lock hook 6 is arranged on the arm 61 of the lock seat 51 , and the arm 61 of the lock seat 51 is provided with a mounting ring 62 , and the mounting ring 62 is swingably mounted on the hinge shaft 64 in the mounting area 3 .

[0039] In one embodiment, the circulation lock groove 5 is arranged on a lock seat 51 , a lock hole 43 is arranged on the inner side surface of the swing arm 4 , and the lock seat 51 is installed in the lock hole 43 .

[0040] In one embodiment, a guide wheel 44 is disposed on the top of the swing arm 4 , and the outer contour of the guide wheel 44 protrudes from the outer side surface of the swing arm 4 .

[0041] Working principle: After the cabinet door is opened: the swing arm 4 is outside the installation area, and the driving motor drives the active gear set to rotate clockwise, thereby pushing the clutch gear to the right limit position of the guide slide, thereby pushing the clutch gear to engage with the driven gear set, and realizing the transmission of the driving power to the swing arm gear 42 through the active gear set, the clutch gear set, and the driven gear set. Driven by 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 re-stores the elastic force and prepares for the next opening action.

[0042] At the same time, the circulating lock hook 6 is hooked with the circulating lock slot 5, and then the driving motor drives the active gear set to rotate counterclockwise, thereby pushing the clutch gear to the left limit position of the guide slide slot, pushing the clutch gear to separate from the driven gear set. The power connection between the gear sets is cut off, and the swing arm, under the action of the elastic device, hooks and locks the circulating lock hook 6 with the circulating lock slot 5.

[0043] At this time, when the user closes the cabinet door, since the swing arm has retracted into the installation area, the user does not need to press the lock door when closing the cabinet door. The cabinet door can be closed under the self-resetting action of the hinge.

[0044] When the user needs to open the cabinet door, he presses the cabinet door inward, and the cabinet door pushes the swing arm to retract inward a certain stroke. The swing arm drives the circulation lock slot 5 to move relative to the circulation lock hook 6, so that the circulation lock hook 6 is disengaged from the circulation lock slot 5. The swing arm loses its locking force at this time, and the elastic force of the torsion spring 7 or the tension spring of the elastic device is released, and the swing arm 4 swings to the outside of the cabinet door around the hinge point. The swing arm 4 pops out from the air avoidance groove 31 through the front end, pushing the cabinet door to open outward. Among them, the design of the guide wheel 44 ensures that the swing arm moves smoothly when it pops out, reducing friction and noise. It should be emphasized that since the clutch gear has been separated, when the swing arm is opened, the power will not be transmitted back to the drive motor 8, so that the swing arm opens more smoothly and stably.

[0045] When the cabinet door pops open, the user can manually push the cabinet door open to the maximum position through the gap in the door. At the same time, the electric mechanism automatically drives the swing arm to reset, and the cycle repeats.

[0046] The electric reset process is completed automatically without the user having to apply additional pressure, which significantly improves the user experience.

[0047] It should be emphasized that: the door opener can also be used with smart home or an external door opening button. When the user sends a door opening signal to it through smart control or the door opening button, the drive motor 8 is activated to reset the swing arm again, so that the swing arm swings inward, thereby disengaging the circulating lock hook 6 from the circulating lock slot 5. Then the drive motor is reversed to drive the clutch gear to separate. The swing arm loses the locking force at this time, and the elastic force of the torsion spring 7 or the tension spring of the elastic device is released, and the swing arm 4 swings to the outside of the cabinet door around the hinge point. The swing arm 4 pops out from the air avoidance slot 31 through the front end, pushing the cabinet door to open automatically outward, thereby realizing the automatic pop-up of the cabinet door.

[0048] Compared with traditional technologies, this case innovatively combines elastic devices, electric mechanisms, gear transmission systems and locking mechanisms to achieve automatic opening and electric reset of the cabinet door. Its core advantage is that the user does not need to press the cabinet door additionally when closing the cabinet door to complete the reset of the rebounder. This function effectively solves the problem of manual reset of the traditional pressing rebounder, is easier to operate, and significantly improves the user experience, so it can be widely promoted and used.

[0049] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
