Description

Technical Field

[0001] This utility model relates to the field of washing machine door cover technology, specifically a washing machine door cover that can slow down the falling speed. Background Technology

[0002] In modern life, washing machines have become an essential household appliance. Washing machines include top-loading washing machines and front-loading washing machines. In the current technology, top-loading washing machines are generally top-loading machines, with a door cover structure on the top of the washing machine. The door cover structure is connected to the top of the washing machine via hinges.

[0003] A search revealed a Chinese patent (CN 221094602 U) entitled "A washing machine door cover and washing machine with a function to slow down the falling speed." The washing machine door cover includes a door cover assembly and a buffer assembly. The door cover assembly includes a door cover body and a door cover rotating shaft. The door cover body has rotating shafts on both sides, connecting it to the sides of the washing machine casing. The buffer assembly is located inside the casing and includes a traction rope, a first roller, and a spring. One end of the spring is fixed to the top surface of the washing machine's worktable, and the other end is connected to the door cover body via the traction rope. When the door cover body is open, the spring is in a free state; when the door cover body needs to be closed, the spring is stretched by gravity, slowing down the falling speed of the door cover body under the spring force. The washing machine door cover provided in this application, through a relatively simple buffer assembly, achieves slow descent of the washing machine door cover, is easy to assemble, and solves the problem of complex washing machine manufacturing processes.

[0004] The washing machine door cover in the aforementioned patent still has some shortcomings. Most existing washing machine door covers reduce the impact when the door falls by setting rubber strips on their sides. However, the rubber strips are prone to aging and damage during long-term use, requiring repeated replacements, which is cumbersome and makes it difficult to effectively reduce the falling speed of the door cover. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a washing machine door cover that can slow down the falling speed. This solves the problem that most existing washing machine door covers reduce the impact when the door falls by setting rubber strips on their sides. However, these rubber strips are prone to aging and damage during long-term use, requiring frequent replacements, which is cumbersome and makes it difficult to effectively reduce the falling speed of the door cover.

[0006] This utility model provides the following technical solution: a washing machine door cover that can slow down the falling speed, including a door cover base, a door cover plate is provided on the top of the door cover base, a sealing top cover is provided at the bottom of the door cover plate, a closing groove is provided at the top of the door cover base, two rotating connecting rods are symmetrically and rotatably arranged on both sides of the bottom of the door cover plate, two closing deceleration components are symmetrically arranged inside the door cover base, two first magnets are symmetrically arranged on the bottom side of the door cover plate, and two second magnets are symmetrically arranged on the top side of the closing groove.

[0007] The closing deceleration assembly includes a side rotation cavity formed on the side of the closing groove. The end of the rotating connecting rod extends rotatably into the side rotation cavity. A first bevel gear is provided at the end of the rotating connecting rod. A fixed horizontal plate is provided inside the side rotation cavity. A transmission connecting rod is rotatably inserted into the fixed horizontal plate. The bottom end of the transmission connecting rod is rotatably connected to the bottom wall of the side rotation cavity. A second bevel gear is provided at the top end of the transmission connecting rod. The second bevel gear meshes with the first bevel gear and is rotatably connected. A first transmission gear is provided at the bottom end of the transmission connecting rod. A support connecting rod is vertically inserted into the side of the transmission connecting rod. The top end of the support connecting rod is rotatably connected to the inner wall of the side rotation cavity through a provided rotating bearing seat. The bottom end of the support connecting rod rotatably passes through the fixed horizontal plate and is rotatably connected to the bottom wall of the side rotation cavity. A reduction gear is provided at the bottom end of the support connecting rod.

[0008] Preferred technical solution 1: The side of the reduction gear meshes with the first transmission gear, and a torsion spring is sleeved on the upper part of the support connecting rod.

[0009] Preferred technical solution 2: The top end of the torsion spring is connected to the inner wall of the side rotating cavity, and the bottom end of the torsion spring is connected to the fixed horizontal plate.

[0010] Preferred technical solution 3: When the door cover plate rotates into the closed groove, the first magnet and the second magnet are magnetically connected.

[0011] This solution makes the door cover plate more stable when it is closed on the door cover base.

[0012] Preferred technical solution four: The diameter of the reduction gear is larger than the diameter of the first transmission gear.

[0013] This solution enables the transmission connecting rod to drive the first transmission gear to rotate, and then achieve speed reduction through the transmission of the reduction gear.

[0014] Preferred technical solution five: Two connecting rods are symmetrically arranged on both sides of the supporting connecting rod body.

[0015] This solution makes the torsion spring fitted on the support connecting rod more stable and can better apply torsional force to the support connecting rod.

[0016] Compared with the prior art, this utility model provides a washing machine door cover that can slow down the falling speed, and has the following beneficial effects:

[0017] (1) This utility model has two closing deceleration components symmetrically arranged on the door cover base. The side rotation cavity of the closing deceleration component is provided with a second bevel gear. The second bevel gear can mesh with the first bevel gear at the end of the rotating connecting rod, thereby driving the transmission connecting rod to rotate. The transmission connecting rod drives the deceleration gear to rotate through the first transmission gear. The diameter of the deceleration gear is larger than that of the first transmission gear. A torsion spring is sleeved on the support connecting rod provided on the deceleration gear. Under the combined action of the deceleration gear and the torsion spring, the rotation speed of the rotating connecting rod can be greatly reduced, which can effectively reduce the falling speed and avoid the risk of the door cover hitting the door cover base too quickly when falling. It also does not require too many rubber pads for cushioning, ensuring the safe and long-term use of the door cover. Attached Figure Description

[0024] Please see Figure 1-4 ,

[0025] Example 1: A washing machine door cover that can slow down the falling speed includes a door cover base 1, a door cover plate 2 is provided on the top of the door cover base 1, a sealing top cover 3 is provided at the bottom of the door cover plate 2, a closing groove 4 is provided at the top of the door cover base 1, two rotating connecting rods 5 are symmetrically rotatably arranged on both sides of the bottom of the door cover plate 2, two closing deceleration components 6 are symmetrically arranged inside the door cover base 1, two first magnets 7 are symmetrically arranged on the bottom side of the door cover plate 2, and two second magnets 8 are symmetrically arranged on the top side of the closing groove 4.

[0026] The closing deceleration assembly 6 includes a side rotation cavity 601 formed on the side of the closing groove 4. The end of the rotating connecting rod 5 extends rotatably into the side rotation cavity 601. A first bevel gear 602 is provided at the end of the rotating connecting rod 5. A fixed horizontal plate 603 is provided in the side rotation cavity 601. A transmission connecting rod 604 is rotatably inserted on the fixed horizontal plate 603. The bottom end of the transmission connecting rod 604 is rotatably connected to the bottom wall of the side rotation cavity 601. A second bevel gear 605 is provided at the top end of the transmission connecting rod 604. The second bevel gear 605 meshes with the first bevel gear 602 and is connected to the transmission. A first transmission gear 606 is provided at the bottom of the transmission connecting rod 604. A support connecting rod 607 is vertically inserted into the side of the transmission connecting rod 604.

[0027] The top end of the support connecting rod 607 is rotatably connected to the inner wall of the side rotating cavity 601 through the provided rotating bearing seat 608. The bottom end of the support connecting rod 607 rotatably passes through the fixed horizontal plate 603 and is rotatably connected to the bottom wall of the side rotating cavity 601. A reduction gear 609 is provided at the bottom of the support connecting rod 607. The side of the reduction gear 609 meshes with the first transmission gear 606 for transmission. A torsion spring 610 is sleeved on the upper part of the support connecting rod 607. The top end of the torsion spring 610 is connected to the inner wall of the side rotating cavity 601, and the bottom end of the torsion spring 610 is connected to the fixed horizontal plate 603.

[0028] Example 2: The difference between this example and Example 1 is that, when the door cover plate 2 rotates into the closed groove 4, the first magnet 7 and the second magnet 8 are magnetically connected.

[0029] This makes the door cover plate 2 more stable when it is closed on the door cover base 1.

[0030] Example 3: The difference between this example and Example 1 is that the diameter of the reduction gear 609 is larger than the diameter of the first transmission gear 606.

[0031] This allows the transmission connecting rod 604 to drive the first transmission gear 606 to rotate, and the gear 609 can then reduce the speed.

[0032] Example 4: The difference between this example and Example 1 is that two connecting rods are symmetrically arranged on both sides of the support connecting rod 607.

[0033] This makes the torsion spring 610 sleeved on the support connecting rod 607 more stable and can better apply torsional force to the support connecting rod 607.

[0034] In this embodiment, most existing washing machine doors reduce the impact when the door falls by setting rubber strips on their sides. However, these rubber strips are prone to aging and damage during long-term use, requiring frequent replacements, which is cumbersome and makes it difficult to effectively reduce the falling speed of the door.

[0035] In summary, in practical implementation, when the user needs to close the door cover 2 onto the door cover base 1, two rotating connecting rods 5 are symmetrically arranged on both sides of the bottom end of the door cover 2. The ends of the rotating connecting rods 5 are inserted into the closing deceleration assembly 6, which is equipped with a second bevel gear 605. The second bevel gear 605 can mesh with the first bevel gear 602 located at the end of the rotating connecting rod 5, thereby driving the transmission connecting rod 604 to rotate. The transmission connecting rod 604 then drives the reduction gear 609 to rotate through the first transmission gear 606. Since the diameter of the first transmission gear 606 is smaller than the diameter of the reduction gear 609, the rotation efficiency of the transmission connecting rod 604 can be greatly reduced when driving the reduction gear 609.

[0036] The top of the support connecting rod 607 on the reduction gear 609 is also fitted with a torsion spring 610. Under the torsion of the torsion spring 610, the rotation speed of the reduction gear 609 can be reduced again, thereby reducing the rotation speed of the rotating connecting rod 5 in the opposite direction. When the door cover 2 connected to the rotating connecting rod 5 closes the top of the door cover base 1, it can effectively slow down the falling action, avoiding the risk of the door cover 2 hitting the door cover base 1 too quickly when falling. It also eliminates the need for excessive rubber pads for cushioning, ensuring the safe and long-term use of the door cover 2.
