Description

Technical Field

[0001] This invention relates to a cabinet door switch, specifically a micro-motion cabinet door push-button switch. Background Technology

[0002] Most households have furniture with hinged doors. Hinges typically connect the door to the cabinet body, opening and closing it via the hinges. Users usually open and close the doors using a protruding handle or similar component. Because of these protruding handles, users often bump into them, posing a safety hazard. Therefore, to address the shortcomings of existing technology, some cabinet doors have been fitted with push-button switches between the cabinet body and the door, allowing opening and closing by pressing. However, most push-button switches on the market require a certain gap in the door to create a trigger travel before the door can be opened. Typically, this gap is 3-5 millimeters, resulting in a large gap and poor cabinet sealing. Therefore, further improvements are necessary. Summary of the Invention

[0027] The invention will be further described below with reference to the accompanying drawings. A micro-motion cabinet door push-button switch includes a door latch 11 fixedly installed on the back of the door 1, and a base 2 installed on the cabinet 10, with a lock cylinder embedded in the base 2.

[0028] The lock cylinder includes a movable groove 21 on the base 2, and a drive seat 3 is slidably installed in the movable groove 21. A guide post 31 is formed by the protrusion on the top of the drive seat 3. Correspondingly, a guide groove 22 is formed in the recess of the base 2. The drive seat 3 can move along the guide groove 22 in the movable groove 21.

[0029] The lock cylinder also includes a hook body 4, which is connected to the drive base 3 by a drive mechanism. One end of the hook body 4 is inserted into the insertion hole on the outside of the drive mechanism, and the other end is bent and locked in the locking groove 25 recessed in the base 2.

[0030] A spring 34 is provided between the drive seat 3 and the base 2. The spring 34 always pushes the drive seat 3 to swing along the axis of the guide post 31, forcing the drive seat 3 to swing along the hanging groove 35 provided on its side wall. The drive seat 3 enters the drive groove 24 opened at the port of the base 2 to push the drive mechanism, causing the hook 4 to slide in the locking groove 25, thereby closing the door 1.

[0031] The driving mechanism includes a swing rod 6, and a swing groove 36 is recessed in the end face of the drive seat 3. The swing rod 6 is embedded in the swing groove 36. One side of the swing rod 6 protrudes at the upper and lower ends to form a rotating shaft 61. The rotating shaft 61 is locked in the rotating hole 26 opened in the base 2. When the drive seat 3 swings, the swing rod 6 swings along the rotating hole 26 in the swing groove 36, driving the hook body 4 to slide in the locking groove 25. The other side of the swing rod 6 has a through hole, and the hook body 4 is inserted into the through hole.

[0032] The swing rod 6 has a guide arc surface protruding from the middle of the body, which is fitted and connected to the swing groove 36; the swing groove 36 has guide slopes that are inclined outward on both sides.

[0033] The drive mechanism includes a drive gear 7 coaxially connected to the guide post 31. One side of the drive gear 7 meshes with a fixed rack 71 formed in the recess of the base 2. The drive mechanism also includes a movable rack 72 meshing with the other side of the drive gear 7. One end of the hook 4 is inserted into the insertion hole of the movable rack 72. When the drive seat 3 swings, the drive gear 7 pushes the movable rack 72 to move in and out, causing the hook 4 to slide in the locking groove 25.

[0034] The outer wall of the movable rack 72 presses against the side wall of the movable groove 21, and the movable rack 72 slides along the side wall.

[0035] The inner end of the drive seat 3 is provided with a spring post 33 protruding, and one end of the spring 34 is wrapped in the spring post 33. The base 2 is provided with a spring groove 23 recessed inward, and the spring 34 is embedded in the spring groove 23. One end of the spring 34 presses against the spring groove 23, and the other end presses against the drive seat 3.

[0036] The upper and lower ends of the drive seat 3 have protruding limit posts 37. Correspondingly, the base 2 is provided with a limit groove 27, and the limit post 37 is locked in the limit groove 27 and swings.

[0037] The locking groove 25 is configured to be conductive at both ends, with a first locking groove 251 and a second locking groove 252 extending from the inner end of the locking groove 25, and a release groove 253 extending from the outer end of the locking groove 25.

[0038] The drive groove 24 is a concave V-shaped opening. The drive groove 24 is set through the front end face of the base 2. The door latch 11 is inserted into the drive groove 24 through the opening and connected to the hanging groove 35 of the drive seat 3.

[0039] The front end face of the drive seat 3 is provided with a reset guide slope that is inclined toward the hanging groove 35.

[0040] Working principle: In the push-button switch of the cabinet door, the lock cylinder includes a movable groove on the base, and a drive seat is slidably installed in the movable groove to engage with the door latch. A guide post is formed by the protrusion of the drive seat on its top body, and correspondingly, a guide groove is formed by the indentation on the base. The guide post is engaged in the guide groove, allowing the drive seat to move along the guide groove within the movable groove.

[0041] A spring is installed between the drive seat and the base. The door latch passes through the drive groove at the port of the base and connects to the hanging groove on the side wall of the drive seat. Since the spring constantly generates a thrust to push the drive seat outward, the drive seat constantly swings along the guide post as its axis. As the door latch extends into the drive groove, it forces the drive seat to sway along the hanging groove, causing the hook connected to one side of the drive seat via the drive mechanism to slide in the locking groove of the base, thereby closing the door. Example 1

[0042] like Figure 2-8 As shown: The driving mechanism includes a swing arm, which is embedded in a swing groove recessed in the end face of the drive seat. A pivot protrudes from the upper and lower ends of one side of the swing arm, forming a rotating shaft. This pivot is engaged in a rotating hole in the base, and the hook is inserted into a hole on the other side of the swing arm. When the latch passes through the drive groove and connects to the hanging groove on the side wall of the drive seat, the latch pushes the drive seat to swing along the guide groove within the movable groove, causing the swing arm to swing synchronously along the rotating hole within the swing groove, and causing the hook to slide within the locking groove. Furthermore, to make the sliding process of the swing arm smoother, a guide arc surface is provided in the middle of the swing arm, and guide slopes are simultaneously provided on both sides of the swing groove. The guide arc surface and the guide slopes are closely connected to ensure that the swing arm does not jam during sliding, making the operation of the push-button switch smoother and improving the user experience. Example 2

[0043] like Figure 9-13As shown, the drive mechanism includes a drive gear coaxially connected to the guide post. One side of the drive gear meshes with a fixed rack on the base, while the other side meshes with a movable rack that abuts the hook body. When the latch passes through the drive groove and connects to the hanging groove on the side wall of the drive seat, the latch pushes the drive seat to sway along the guide groove within the movable groove. As the guide post slides up and down along the guide groove, it drives the drive gear to rotate synchronously, pushing the movable rack meshing with the drive gear to move up and down, causing the hook body to slide within the locking groove. Furthermore, the outer wall of the movable rack presses against the side wall of the movable groove, limiting the sliding of the movable rack along this side wall and preventing swaying. The hook body, which is hinged to the movable rack, can then slide along the locking groove.

[0044] In the two embodiments described above, when the drive seat experiences a slight sway, the lever principle is utilized. Through the swing of the lever or the interaction of the drive gear and rack, the travel distance of the hook is effectively extended, thus achieving trigger opening even with a small trigger stroke. This eliminates the need for users to press the door latch extensively, reducing the effort and time required, saving time and effort, and offering simple and convenient operation with a simple structure. According to the applicant's measurements, the trigger stroke in this case can be less than 2 millimeters, or even zero gap. Opening is achieved solely through the deformation of the cabinet door panel, significantly improving the cabinet door's sealing performance.

[0045] Furthermore, in this case, the two ends of the locking groove of the drive seat are interconnected. A first locking groove and a second locking groove extend from the inner end of the locking groove, and a release groove extends from the outer end of the locking groove. When the door is forcibly opened without a push-to-open operation, because the drive seat is in a tilted position when the door is closed, as the user pulls the door outward, the hook disengages from the first locking groove along the locking groove and slides down the channel of the locking groove to the second locking groove. At this time, under the inertial thrust of the spring, the drive seat is pushed outward, the hook disengages from the second locking groove, and slides outward along the channel of the locking groove to the release groove, thus forcibly opening the door. This achieves forced release of the door without the need for a push-to-open mechanism. While retaining the traditional push-to-open function, the addition of a forced release function enriches the diversity of door opening methods. Even if the push-button switch fails, the cabinet door can still be forcibly opened, preventing inconvenience in accessing items inside the cabinet due to switch damage. It also avoids the situation where users, unaware of the push-button opening mechanism, can force the door open by pulling it outwards, thus preventing damage to the door opener. The versatility of the cabinet door opening and closing methods extends the lifespan of the push-button switch, further reducing furniture usage costs, and therefore, it can be widely adopted.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
