Description

Technical Field

[0001] This invention relates to the technical field of push-button switch assemblies, and in particular to a discrete push-button switch assembly for use in wine cabinets. Background Technology

[0002] Currently, the discrete push-button switch assembly of the present technology consists of two independent components: a switch device and a pusher. The pusher and the switch device are set opposite each other, and the pusher rod on the pusher is directly facing the sensing area of ​​the switch device. An appropriate gap (press stroke) is set between the top of the pusher rod and the sensing area of ​​the switch device. Pushing the pusher moves the pusher so that the top of the pusher rod touches the switch device, thereby triggering the switch device to send an electrical signal to the electronic control device.

[0003] This push-button switch assembly is used in wine cabinets. The switch device is installed on the frame of the front opening of the wine cabinet body, and the push-button is installed on the frame of the inner side of the wine cabinet door. Since the installation distance (preset gap) between the push-button and the switch device is predetermined based on the gap between the door and the cabinet body, the length of the push-button rod on the push-button is fixed, and the backward movement of the door is also limited. Various factors can cause the gap between the wine cabinet door and the cabinet body to increase or decrease when the door is closed. These factors include height tolerances in the sealing strip installed on the wine cabinet door causing its cross-section to shrink or increase, uneven assembly of the sealing strip on the inner side of the door, and closure tolerances in the hinges installed on the door. Since the preset gap between the push-button and the switch device is fixed, an increased gap will cause the push-button rod on the push-button to not properly engage with the switch device, resulting in reduced sensing sensitivity; a decreased gap will cause the push-button rod to become relatively longer, leading to excessive impact on the switch device and damage to the switch device components. To ensure optimal fit between the push-button and the switch, when the gap between the door and the cabinet opening increases, the mounting side of the push-button or switch is raised appropriately; when the gap decreases, a portion of the top of the push-button rod is removed to reduce its overall length. Therefore, installing the wine cabinet door and adjusting the push-button switch assembly is quite complex, resulting in low efficiency and inconvenience in assembling the wine cabinet door. Summary of the Invention

[0004] The purpose of this invention is to provide a push-button switch assembly to solve the problems mentioned in the background art, where the distance between the switch device and the presser can be flexibly adjusted. This push-button switch assembly, applied to wine cabinets, allows for adjustment of the switch device's position via a shifting device based on changes in the gap between the door and the cabinet body, ensuring the switch device and presser return to a preset distance and maintain optimal fit. This enables quick and easy adjustment of the push-button switch assembly. Furthermore, the presser's lever is made of rubber, providing appropriate elasticity to better protect the switch device and effectively extend its service life.

[0005] To achieve the above objectives, the present invention proposes the following technical solution:

[0006] A push-button switch assembly includes a pusher, a switching device, and a shifting device. The pusher and the switching device are arranged opposite to each other. The switching device is mounted on the shifting device. The shifting device drives the switching device to move linearly to change the horizontal position of the switching device, and the distance between the switching device and the pusher can be flexibly adjusted. When the pusher lever on the pusher touches the sensing area of ​​the switching device, it triggers the switching device to send an electrical signal to an electronic control device.

[0007] Specifically, the displacement device includes a fixed frame, a sliding arm, bolts and nuts. A sliding groove is provided on the right side of the fixed frame, and through holes are provided on the front and rear sides of the fixed frame, with the through holes communicating with the sliding groove.

[0008] A screw hole is provided longitudinally at the left end of the sliding arm. The left end of the sliding arm extends into the slide groove from the right side of the fixing frame. The bolt passes through the through hole on the front side of the fixing frame, the screw hole on the sliding arm, and the through hole on the rear side of the fixing frame from front to back. The end of the bolt is threadedly connected to the nut. The switching device is horizontally arranged longitudinally at the right end of the sliding arm. The sensing area of ​​the switching device faces forward and is opposite to the pressing rod on the presser.

[0009] When the installation distance between the presser and the switch device increases or decreases compared to the preset distance, use a tool to turn the bolt. The bolt drives the sliding arm to move horizontally forward or backward within the slide groove. The sliding arm drives the switch device to move linearly forward or backward to adjust the distance between the switch device and the presser, so that the switch device and the presser return to the preset interval, and the presser and the switch device maintain the best fit.

[0010] Furthermore, it also includes a sleeve, which is longitudinally disposed on the right end of the slide arm. The switching device is placed inside the sleeve, and the sensing area of ​​the switching device is disposed on the front opening of the sleeve. This greatly facilitates the installation of cylindrical switching devices and avoids damage caused by frequent collisions and impacts between the switching device and the presser, thus better protecting the switching device.

[0011] Furthermore, the presser includes a cylindrical pressing rod and a fixing plate. The pressing rod is integrally molded from rubber material. The moderately elastic pressing rod has a buffering effect when pressed on the switching device, which can better protect the switching device, effectively extend the service life of the switching device, and avoid damage to the switching device caused by excessive impact from the pressing rod.

[0012] The fixed plate is provided with a stepped hole, and the pressing rod includes a rod seat and a pressing rod body. The pressing rod passes through the stepped hole from the front side of the fixed plate to the rear. The rod seat is fitted into the stepped hole, and the pressing rod body extends out from the rear side of the fixed plate, making the pressing device very convenient and quick to assemble.

[0013] The fixing plate is made of one piece of metal material, which makes the presser more securely installed.

[0014] The rod head of the pressure rod is shaped like a spherical cap or a frustum, and the rod head is directly facing the center of the sensing area of ​​the switching device. The spherical cap or frustum shape of the rod head allows for better cooperation with the switching device, effectively improving the sensitivity of the switching device.

[0015] Specifically, the sliding arm is rectangular parallelepiped in shape, and the cavity of the sliding groove is rectangular parallelepiped in shape.

[0016] The height of the left end of the sliding arm is slightly smaller than the height of the cavity of the slide groove. The sliding arm is placed into the cavity of the slide groove, and the top surface of the sliding arm is close to the top wall of the cavity of the slide groove. This effectively prevents the left end of the sliding arm from wobbling up and down when moving in the slide groove, keeping the switching device in a straight line on the central axis of the pressing rod, so that the pressing rod can accurately press on the sensing area of ​​the switching device.

[0017] Preferably, a gap of 0.5-2mm is provided between the top surface of the left end of the sliding arm and the top wall of the cavity of the sliding groove. The gap is coated with grease to limit the swaying of the sliding arm while ensuring smooth sliding.

[0018] This invention also proposes a wine cabinet using the aforementioned push-button switch assembly, comprising a cabinet body and a door body. The push-button is fixedly installed on the rear frame of the door body, and the shifting device is fixedly installed within the frame of the front opening of the cabinet body. The sensing part of the switch device extends forward from a through hole in the frame of the front opening of the cabinet body. When the door body is closed, the push-button and the switch device are opposite each other, with the tip of the push-button facing the sensing area of ​​the switch device. When the gap between the door body and the cabinet body increases or decreases, causing the default distance between the switch device and the push-button to increase or decrease, during adjustment of the push-button switch assembly, the bolt is rotated, which drives the sliding arm to move horizontally back and forth within the sliding groove. The sliding arm drives the switch device to move forward or backward in a straight line to adjust the longitudinal position of the switch device, so that the push-button and the switch device return to the preset interval, maintaining the optimal matching state between the push-button and the switch device.

[0019] When the wine cabinet door needs to be opened electrically, the user presses lightly on the front of the door. The door with the presser moves slightly backward, and the tip of the presser touches the sensing area of ​​the switch device, thereby triggering the switch device to send an electrical signal to the electronic control device inside the wine cabinet. The electronic control device then controls the electric door hinge to open the door.

[0020] This invention provides a push-button switch assembly and a wine cabinet using the same assembly. Because the switch is mounted on a moving device, when the preset distance between the switch and the press changes, or when the gap between the door and the cabinet increases or decreases when the door is closed, simply turning a bolt with a tool drives a sliding arm to move linearly forward or backward. The sliding arm then moves the switch forward or backward, achieving stepless adjustment of the switch's longitudinal position. This restores the distance between the switch and the press to the preset interval, maintaining optimal alignment between them. This allows for convenient and quick adjustment of the push-button switch assembly while avoiding easy damage to the switch. Attached Figure Description

For example, "connection" can be a fixed connection, a movable connection, or a detachable connection; it can also be a mechanical connection or a circuit connection; it can be a direct connection or an indirect connection through an intermediate medium; it can also be the internal communication of two components or the interaction relationship between two components; unless otherwise explicitly specified and limited, those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances. The terms "front," "rear," "left," "right," "up," and "down" only describe the relative positions of the components in the accompanying drawings and are not intended to limit the present invention.

[0033] Example 1

[0034] like Figures 1 to 6 As shown, a push-button switch assembly includes a pusher 1, a switch device 2, and a shifting device 3. The pusher 1 and the switch device 2 are arranged opposite to each other. The switch device 2 is mounted on the shifting device 3. The shifting device 3 drives the switch device 2 to move linearly to change the horizontal position of the switch device 2, thereby adjusting the distance between the pusher 2 and the pusher 1. When the pusher 1 moves and the push rod on the pusher presses against the sensing area of ​​the switch device 2, the switch device 2 is triggered to send an electrical signal to the electronic control device.

[0035] Specifically, the displacement device 3 includes a fixed frame 31, a sliding arm 32, a bolt 33 and a nut 34. A sliding groove 4 is provided on the right side of the fixed frame 31, and the sliding groove 4 passes through the left side of the fixed frame 31. Through holes 5 are provided on the front and rear sides of the fixed frame 31, and the through holes 5 communicate with the sliding groove 4.

[0036] The left end of the sliding arm 32 is provided with a screw hole 6 along the longitudinal direction. The left end of the sliding arm 32 extends into the sliding groove 6 from the right side of the fixing frame 31. The bolt 33 passes through the through hole 5 on the front side of the fixing frame, the screw hole 6 on the sliding arm, and the through hole 5 on the rear side of the fixing frame from front to back. The end of the bolt 33 is threadedly connected to the nut 34. The switching device 2 is arranged horizontally along the longitudinal direction on the right end of the sliding arm 32. The sensing area of ​​the switching device 2 faces forward and is opposite to the pressing rod on the presser 1.

[0037] When the installation distance between the presser and the switch device increases or decreases compared to the preset distance, use a tool to rotate the bolt 33. The bolt 33 drives the sliding arm 31 to move horizontally forward or backward within the sliding groove 6. The sliding arm 31 drives the switch device 2 to move linearly forward or backward to change the longitudinal position of the switch device 2, thereby adjusting the distance between the switch device 2 and the presser 1, so that the switch device 2 and the presser 1 return to the preset distance, and the presser 2 and the switch device 1 maintain the best fit.

[0038] Furthermore, it also includes a sleeve 7, which is longitudinally arranged on the right end 322 of the slide arm. The switch device 2 is installed inside the sleeve 7, and the sensing area of ​​the switch device 2 is located on the front opening of the sleeve 7. This greatly facilitates the installation of the cylindrical switch device 2, while avoiding frequent collisions and impacts between the switch device 2 and the presser 1, thus better protecting the switch device 2.

[0039] Furthermore, such as Figure 2 and Figure 6 As shown, the presser 1 includes a cylindrical pressing rod 11 and a fixing plate 12. The pressing rod 11 is integrally molded from rubber material. When the rod head of the moderately elastic pressing rod presses on the switching device, it has a buffering effect, which can better protect the switching device, effectively extend the service life of the switching device, and avoid damage to the switching device caused by the pressing rod hitting the switching device too hard.

[0040] like Figure 4 and Figure 5As shown, the fixed plate 12 has a stepped hole 121 at its center. The pressing rod 11 includes a flat circular rod base 111 and a cylindrical pressing rod body 112. The pressing rod 11 passes through the stepped hole 121 from the front side of the fixed plate 12 to the rear side. The rod base 111 is fitted into the stepped hole 121, and the pressing rod body 112 extends out from the rear side of the fixed plate 12, making the assembly of the presser very convenient and quick.

[0041] The fixing plate 12 is made of metal material in one piece, which makes the presser more securely installed.

[0042] The rod head of the pressure rod 112 is shaped like a spherical cap or a frustum. The rod head of the pressure rod 112 is directly facing the center of the sensing area of ​​the switching device 2. The spherical cap or frustum shape of the rod head has a better fit with the switching device 2, which is beneficial to improving the sensitivity of the switching device 2.

[0043] Specifically, the sliding arm 32 is rectangular parallelepiped, and the chamber of the sliding groove 4 is rectangular parallelepiped.

[0044] The height of the left end of the sliding arm 32 is slightly smaller than the height of the chamber of the slide groove 4. The sliding arm 32 is placed inside the chamber of the slide groove 4, and the top surface of the sliding arm 32 is close to the top wall of the chamber of the slide groove 4. This effectively prevents the left end of the sliding arm 32 from wobbling up and down when it moves in the slide groove 4, keeping the switch device 2 on the central axis 1A of the pressing rod and moving in a straight line, so that the pressing rod 11 can accurately press on the sensing area of ​​the switch device 14.

[0045] Preferably, a gap 8 with a height difference of 0.5-2mm is provided between the top surface of the left end of the slide arm 32 and the top wall of the cavity of the slide groove 4. The gap 8 is coated with grease to limit the swaying of the slide arm 32 while ensuring smooth sliding of the slide arm 32.

[0046] Example 2

[0047] like Figures 7 to 9 As shown, a wine cabinet using the aforementioned push-button switch assembly includes a cabinet body 91 and a door body 92. The pusher 1 is mounted and fixed on the rear frame of the door body 92. The switch device 2 and the shifting device 3 are respectively disposed within the frame of the front opening of the cabinet body 91. The sensing part of the switch device 2 extends forward from a through hole in the frame of the front opening of the cabinet body 91. When the door body 32 is closed, the pusher 1 and the switch device 2 are opposite each other, and the rod head 111 on the pusher is directly facing the sensing area of ​​the switch device 2. When the wine cabinet door needs to be opened electrically, the user presses lightly on the front of the door body 92, causing the door body 32 to move slightly backward with the pusher 1. The rod head 111 on the pusher touches the sensing area of ​​the switch device 2, thereby triggering the switch device 2 to send an electrical signal to the electronic control device of the wine cabinet. The electronic control device then controls the electric door hinge to open the door.

[0048] The principle of this invention is as follows: When assembling the wine cabinet door, the presser 1 is fixedly installed on the rear frame of the door body 92, and the shifting device 3 is fixedly installed inside the frame of the front opening of the cabinet body 91. Due to issues such as the sealing strip on the door being too thick or too thin, uneven installation of the sealing strip on the inner side of the door, or closure tolerances in the hinges installed on the door, the gap between the door body 92 and the cabinet body 91 may increase or decrease, meaning the preset distance between the presser 1 and the switching device 2 changes. By using a tool to rotate the bolt, the bolt drives the sliding arm to move forward or backward in a straight line. The sliding arm then moves the switching device forward or backward, achieving stepless adjustment of the longitudinal position of the switching device to adapt to the change in distance. This allows the presser and the switching device to return to the preset distance and maintain optimal fit, enabling convenient and quick adjustment of the press switch assembly.

[0049] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
