Description

Technical Field

[0001] This utility model relates to the field of door opening device technology, and in particular to a push rod assembly for opening a door and a door opening mechanism using the same. Background Technology

[0002] As living standards improve, dishwashers, microwave ovens, and steam ovens have gradually become standard kitchen appliances.

[0003] When using the above electrical appliances, it is often necessary to open or close the door. Existing technology uses a single push rod to drive a gripper to tighten or release the latch connected to the door, thus enabling the door to open and close. During this process, the gripper must tighten or release the latch between the cabinet and the door, causing the front end of the gripper to extend further beyond the cabinet after the door is opened, which is unsightly and results in a slower opening speed, negatively impacting the customer experience. Utility Model Content

[0004] To address the aforementioned shortcomings, the primary objective of this utility model is to propose a push rod assembly for opening doors, employing two sliding components with opposite directions of operation. This solves the problem that the locking component needs to extend significantly beyond its initial position when opening the door, thus affecting aesthetics and slowing the opening speed. The assembly includes:

[0005] Locking components;

[0006] A first sliding component, wherein the locking component is rotatably connected to the first sliding component;

[0007] The second sliding component is disposed adjacent to the first sliding component, and the second sliding component is used to control the opening and closing state of the locking component;

[0008] When the push rod assembly is in operation, the first sliding assembly and the second sliding assembly move in opposite directions.

[0009] In some embodiments, the push rod assembly further includes a locked member and two locking components. The two locking components are symmetrically arranged along the sliding directions of the second sliding component and the first sliding component. Each locking component includes a locking member, and the locking members of the two locking components form a locking engagement with the locked member on the side facing the locked member.

[0010] In some embodiments, the first sliding component includes a first sliding portion, and the second sliding component includes a second sliding portion and a locking engagement portion. The locking engagement portion is located at the end of the second sliding portion facing the locking component, and the second sliding portion drives the locking engagement portion to move.

[0011] In some embodiments, the two locking members are provided with an opening and closing gap on the side facing the second sliding component, and the locking engagement portion forms a rotational engagement with the opening and closing gap, so that the two locking components move away from or toward the locked member, thereby controlling the opening and closing of the locking components.

[0012] In some embodiments, the first sliding component and the second sliding component are connected adjacently by a snap-fit ​​connection. The first sliding component is provided with a guide groove on the side facing the second sliding component. The locking engagement part is located in the guide groove, and the guide groove is used to limit the movement position of the locking engagement part.

[0013] The push rod assembly further includes a top connector, which is disposed on the side of the second sliding assembly opposite to the first sliding assembly. The top connector is disposed in the guide groove and connected to the second sliding part. The end of the top connector is located on the side of the locking engagement part facing the locking member.

[0014] In some embodiments, the locking assembly is a gripper, the locking member is a claw, the locked member is a latch, the second sliding assembly is a second push rod, the second sliding portion is a second rack, the locking engagement portion is a tip, the first sliding assembly is a first push rod, the first sliding portion is a first rack, and the top connector is a top rod.

[0015] In some embodiments, the push rod assembly is provided with a door closing station, a door opening station, and an exhaust station;

[0016] When the push rod assembly is in the closing position, the first sliding assembly moves in the direction opposite to the locked part, the second sliding assembly moves in the direction of the locked part, and the locking engagement part is just before entering the opening and closing gap.

[0017] When the push rod assembly is in the door opening position, the first sliding assembly moves toward the direction opposite to the locked member, the second sliding assembly moves toward the locked member, and the locking engagement part is located between the opening and closing gaps.

[0018] When the push rod assembly is in the exhaust position, the first sliding assembly moves toward the locked member, and the second sliding assembly moves toward the opposite direction of the locked member. The first sliding assembly drives the locking assembly and the locked member to move. At this time, the locking engagement part is located outside the opening and closing gap.

[0019] On the other hand, this application also provides a door opening mechanism using a push rod assembly, installed inside the enclosure of electrical equipment, comprising:

[0020] The aforementioned push rod assembly for opening the door;

[0021] The base box contains the push rod assembly. The base box has a locking component inlet and outlet. Two elastic members are provided on both sides of the locking component inlet and outlet. The elastic members are used to close the locking assembly.

[0022] In some embodiments, the door opening mechanism further includes a drive assembly, which includes a driver, a first push gear, a second push gear, and a plurality of transmission gears;

[0023] The driver drives the first push gear and the second push gear to rotate synchronously through a plurality of transmission gears, and the first push gear and the second push gear rotate in opposite directions.

[0024] In some embodiments, the door opening mechanism further includes multiple sensors;

[0025] Multiple sensors are arranged at intervals on the base box, and the sensors are signal-connected to the driver; the first sliding component has an outward protrusion on the side facing the sensor, and the outward protrusion cooperates with the multiple sensors to determine the position of the first sliding component and the second sliding component and the working status of the door opening mechanism.

[0026] The push rod assembly of this application utilizes the counter-movement of a first sliding component and a second sliding component, thereby enabling the second sliding component and the locking component to cooperate within a minimal space. This results in a smaller range of motion for the locking component during locking and opening, and it remains inside the door when open or locked, extending outside only when steam needs to be released. This push rod assembly is not only simple in structure and low in cost, but also stable in use and occupies little space, meeting the aesthetic requirements of various devices.

[0039] A push rod assembly for opening a door, the push rod assembly 3 is installed in a base box 1, the front side of the base box 1 is provided with a lock tongue inlet 10, the push rod assembly 3 includes a first push rod 31, a second push rod 32 and a gripper 33; the gripper 33 includes two claws 331;

[0040] Both the first push rod 31 and the second push rod 32 extend in the front-rear direction. The second push rod 32 is slidably mounted on the bottom surface of the first push rod 31. The rear ends of the two claws 331 are rotatably mounted on the front ends of the first push rod 31, and the two claws 331 are spaced apart from each other. The front ends of the claws 331 are directed toward the bolt inlet / outlet 10, and the two claws 331 are used to perform a clamping or releasing action on the bolt 6 within the base box 1.

[0041] The gripper 331 has a protrusion 3312 in the middle; the two protrusions 3312 are arranged opposite each other, and there is an opening and closing gap 330 between the two protrusions 3312; the front end of the second push rod 32 has a tip 321, which is used to insert into the opening and closing gap 330 so that the two grippers 331 open.

[0042] The first push rod 31 has a first rack 312 on one side, and the second push rod 32 has a second rack 322 on one side; the first rack 312 and the second rack 322 are used to mesh with the first push gear 22 and the second push gear 23 respectively, and the first push rod 31 and the second push rod 32 move in opposite directions.

[0043] like Figure 1 and Figure 6 As shown, the first push rod 31 is provided with a side wing portion 314, and the side wing portion 314 is provided with a receiving groove 3142 on the side opposite to the bottom box 1. A rotating shaft 3141 is provided in the receiving groove. The gripper 33 is also provided with a rotating engagement portion 332 facing the first push rod 31. The gripper 33 is disposed in the receiving groove 3142 and forms a rotating engagement with the rotating shaft 3141. In some embodiments, the rotating engagement portion 332 is provided with a rotating guide groove that matches the rotating shaft 3141. The rotating guide groove and the rotating shaft 3141 form a rotating engagement, so that the rotating engagement portion 332 can drive the gripper 331 to rotate. This application provides that by setting the rotating shaft 3141 of the gripper 33 on the first push rod 31, the gripper 33 can rotate around the rotating shaft 3141, while the first push rod 31 can drive the gripper 33 to move through the rotating shaft 3141.

[0044] Figure 1 This is a schematic diagram of the push rod assembly for opening doors according to the present invention. Figure 2 for Figure 1 A structural diagram viewed from below. Figure 3 for Figure 1 A structural schematic diagram of the first push rod from below. Figure 4 This is a schematic diagram of the second push rod. Figure 5This is a schematic diagram of the installation structure of the push rod assembly, the first push gear, the second push gear, and the latch, wherein the latch 6 is connected to the door to be opened or closed. The latch inlet / outlet 10 penetrates the front and bottom surfaces of the base box 1.

[0045] like Figure 1-5 and Figure 8 In the illustrated embodiment, when the latch 6 extends into the latch inlet / outlet 10 and is located between the two claws 331, the first push gear 22 drives the first rack 312 to move, which in turn drives the first push rod 31 to move backward. The first push rod 31 pulls the latch 6 backward, and the two claws 331 close and hold the latch 6 tightly. At the same time, the second push gear 23 drives the second rack 322 to move, which in turn drives the second push rod 32 to move forward. Before the tip 321 of the second push rod 32 inserts into the opening / closing gap 330 between the two protrusions 3312, the first push gear 22 and the second push gear 23 are stopped. This allows the door gap between the corresponding parts of the door and the electrical box to be closed. The first push rod 31 is defined as being in the closing position at this time.

[0046] like Figure 1-5 and Figure 6 In the embodiment shown, when it is necessary to open or close the door, the first push gear 22 and the second push gear 23 can be driven to rotate synchronously by the driver 21, and the first push rod 31 can be moved backward. At the same time, the second push rod 32 can be moved forward, so that the tip 321 of the front end of the second push rod 32 is inserted into the opening and closing gap 330, so that the two claws 331 open and release the latch 6. The driver 21 stops running, and the door can be rotated and opened by itself by the rotation of the door hinge. The first push rod 31 is defined as being in the door opening position at this time.

[0047] During the closing or opening process, the clamping or releasing action of the two claws 331 on the latch 6 is completed within the bottom box 1.

[0048] Furthermore, it also includes at least two tension limiting sliders 36 and two tension limiting springs 37;

[0049] The two tension limiting sliders 36 are respectively installed near the left and right edges of the latch entrance / exit 10; the two ends of the tension limiting sliders 36 are a sealing end 361 and an opening end 362, respectively; the sealing end 361 is used to abut against the left side of the left claw 331 or the right side of the right claw 331; one end of the tension limiting spring 37 passes through the opening end 362 and is inserted into the tension limiting slider 36, and the other end of the tension limiting spring 37 is used to abut against the inner sidewall of the base box 1.

[0050] like Figure 5-8As shown, the distance between the two grippers 331 is limited by the cooperation of two tension limiting sliders 36 and two tension limiting springs 37, that is, the opening degree of the two grippers 331 is limited. When the tip 321 is located behind the opening and closing gap 330, that is, when the tip 321 is not inserted into the opening and closing gap 330, the two grippers 331 can be kept closed and hold the latch 6 to complete the door closing or air venting operation; it can also prevent the two grippers 331 from being damaged by friction with the left and right edges of the latch entrance 10.

[0051] like Figure 1-5 and Figure 7 In the illustrated embodiment, if it is necessary to open the door gap between the corresponding parts of the door and the electrical box to allow exhaust to escape, but the door is not opened, the first push gear 22 and the second push gear 23 can be driven simultaneously by the driver 21. The first push gear 22 drives the first push rod 31 forward through the first rack 312, and the second push gear 23 drives the second push rod 32 backward through the second rack 322. While keeping the two claws 331 tightly gripping the latch 6, the front ends of the two claws 331 and the latch 6 are partially exposed in front of the latch entrance 10. When the door gap between the corresponding parts of the door and the electrical box reaches the required opening degree, the driver 21 stops running, so that the heat and / or water vapor in the electrical box can be discharged outward through the door gap. At this time, the first push rod 31 is defined as being in the exhaust position.

[0052] Furthermore, the push rod assembly 3 also includes a push rod 35;

[0053] The push rod 35 extends in the front-back direction and is inserted into the bottom surface of the second push rod 32; the front end of the push rod 35 is exposed in front of the first push rod 31 and the second push rod 32, and the front end of the push rod 35 is located between the two grippers 331.

[0054] like Figure 1 and Figure 2 As shown, when the opened door is closed by external force, the latch 6 extends through the latch inlet 10 into the space between the two open claws 331. The latch 6 abuts against the front end of the push rod 35, causing the push rod 35 to move backward under force, and driving the second push rod 32 to retract and leave the opening and closing gap 330, so that the two claws 331 close again and hold the latch 6, thus completing the closing of the door.

[0055] Furthermore, the front end of the first push rod 31 is also provided with a guide groove 311;

[0056] The guide groove 311 is recessed inward at the front end of the first push rod 31. The guide groove 311 extends in the front-back direction and is used to accommodate the front half of the second push rod 32 and the rod body of the top rod 35 stacked on top of each other.

[0057] like Figure 2 and Figure 5 As shown, the guide groove 311 can limit the trajectory of the second push rod 32 and the top rod 35 to move back and forth, avoid the second push rod 32 and the top rod 35 from being misaligned, thereby improving the accuracy of the second push rod 32 inserting into the opening and closing gap 330, and ensuring that when the opened door is closed by external force, the latch 6 can accurately abut against the front end of the top rod 35.

[0058] Furthermore, the first push rod 31 is also provided with an outward protrusion 313;

[0059] The protrusion 313 protrudes outward from the other side of the first push rod 31, and the protrusion 313 and the first rack 312 are located on the left and right sides of the rear end of the first push rod 31, respectively.

[0060] The protrusion 313 is used to trigger the trigger end of the sensor that detects the position of the first push rod 31.

[0061] exist Figure 6 Multiple sensors are mounted on the multiple mounting posts 12, with the trigger ends of the sensors facing the first push rod 31. The sensors are signal-connected to the driver 21 that drives the first push gear 22 and the second push gear 23.

[0062] like Figure 5 and Figure 6 As shown, an outwardly protruding part 313 is provided on the other side of the rear end of the first push rod 31 away from the first rack 312. When the first push rod 31 is in or away from the door closing position, door opening position, exhaust position or initial position, the outwardly protruding part 313 triggers the corresponding sensor and sends a signal to the driver 21, so that the driver 21 can start or stop according to the corresponding preset program, thereby driving the first push rod 31 and the second push rod 32 to complete the relevant corresponding operations.

[0063] When the opened door is closed by external force, a sensor can be set to match the protrusion 313 on the first push rod 31 at this time, so that the first push rod 31 and the second push rod 32 can be driven by the driver 21 to complete the corresponding operation.

[0064] Furthermore, this utility model proposes a door opening mechanism using a push rod assembly, which is installed inside the enclosure of electrical equipment. The push rod assembly for opening the door described above includes a base box 1, a drive assembly 2, and the push rod assembly 3.

[0065] The bottom box 1 has a locking tongue inlet / outlet 10, which penetrates the front end and bottom surface of the bottom box 1;

[0066] The drive assembly 2 includes the driver 21, the first push gear 22, the second push gear 23, and a plurality of transmission gears;

[0067] The driver 21 drives the first push gear 22 and the second push gear 23 to rotate synchronously through a plurality of transmission gears, and the first push gear 22 and the second push gear 23 rotate in opposite directions.

[0068] like Figure 1-8 As shown, by controlling the start and stop of the driver 21, the stroke of the first push gear 22 and the second push gear 23 can be controlled, thereby correspondingly controlling the relative position of the first push rod 31 and the second push rod 32, as well as the position of the tip 321 relative to the opening and closing gap 330, and thus controlling the first push rod 31 to complete the operation of closing the door, opening the door, venting, or resetting to the initial position. Since the first push rod 31 and the second push rod 32 move in opposite directions, the first push rod 3 completes the stroke between the closing position, the opening position, or the resetting to the initial position in the bottom box 1, thereby preventing the gripper 33 from moving relative to the initial position towards the lock tongue inlet / outlet 10 during the operation of closing the door, opening the door, and resetting to the initial position.

[0069] In addition, the length of the jaw 33 exposed outside the equipment housing during exhaust can be adjusted by adjusting the distance between the tip 321 and the opening / closing gap 330 in the initial position.

[0070] Furthermore, it also includes multiple sensors; multiple mounting posts 12 are vertically installed on the bottom surface of the base box 1;

[0071] The plurality of mounting posts 12 are arranged at intervals in the front-to-back direction, and the first push rod 31 is located between the mounting posts 12 and the first push gear 22; the first push rod 31 is also provided with an outward protrusion 313;

[0072] The plurality of sensors are respectively mounted on the plurality of mounting posts 12; the sensors are signal connected to the driver 21;

[0073] The protrusion 313 protrudes outward from the other side of the first push rod 31, and the protrusion 313 and the first rack 312 are located on the left and right sides of the rear end of the first push rod 31, respectively.

[0074] The protrusion 313 is used to trigger the trigger end of the sensor corresponding to the position of the first push rod 31.

[0075] like Figure 7-8In the embodiment shown, when the first push rod 31 is in the closing position, opening position, exhaust position or initial position, the corresponding sensor can be triggered by the external protrusion 313 to control the start and stop of the driver 21, so that the door opening mechanism using the push rod assembly can complete the operation steps of closing, opening, exhausting or resetting to the initial position.

[0076] Furthermore, this also includes the cover;

[0077] The cover is used to close with the base box 1 and cover the drive assembly 2, the push rod assembly 3 and the multiple sensors.

[0078] By closing the cover with the base box 1, the drive assembly 2, push rod assembly 3 and multiple sensors can be protected, preventing the drive assembly 2, push rod assembly 3 and multiple sensors from being touched during operation and becoming loose or malfunctioning.

[0079] In summary, such as Figure 1-8 The embodiment of the present invention shown includes a push rod assembly for opening the door, comprising a first push rod 31 and a second push rod 32 with opposite directions of movement. The two claws 331 are opened by inserting the tip 321 of the front end of the second push rod 32 into the opening and closing gap 330. During the opening and closing process, the front end of the claws 331 can be prevented from protruding too much outside the box, which can improve the aesthetics of the equipment during use and improve the customer experience.

[0080] Furthermore, the door opening mechanism using the above-mentioned push rod assembly proposed in this utility model controls the stroke of the first push gear 22 and the second push gear 23 by controlling the start and stop of the driver 21, thereby correspondingly controlling the relative position of the first push rod 31 and the second push rod 32, as well as the position of the tip 321 relative to the opening and closing gap 330. This allows the clamping or releasing action of the two grippers 331 on the latch 6 to be completed within the base box 1, and avoids the grippers 33 from extending too much out of the latch entrance / exit 10 during the operation of closing, opening, and resetting to the initial position. It has the advantages of compact overall structure and small installation space.

[0081] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
