Description

TECHNICAL FIELD

[0001] The utility model relates to intelligent bathroom technical field, especially a gear box for intelligent closestool, intelligent closestool cover and intelligent closestool. BACKGROUND

[0002] As a kind of integrated multiple intelligent functions bathroom equipment, one of its core components is gear box system. Gear box is mainly used to drive flap, circle and other functions in intelligent closestool, and its performance and reliability directly affect user experience.

[0003] However, there are still some technical problems in the design and application of the gear box system of the existing intelligent closestool, mainly using the following schemes:

[0004] First, ratchet connection scheme: this kind of scheme usually uses plastic buckle structure, and realizes overload protection through ratchet mechanism. However, plastic buckle structure is easy to wear in long-term use, and there are certain limitations in durability and reliability, resulting in shortening of gear box life.

[0005] Second, friction plate structure scheme: this kind of scheme realizes overload protection through the superposition of multiple layers of friction plate. However, the incoming material consistency of friction plate is relatively high, and if the friction plate quality is uneven or improperly installed, it is easy to cause failure, and the stability and consistency are difficult to guarantee.

[0006] The above information disclosed in the background of the present application is only for understanding the background of the concept of the present application, and does not indicate or imply that it contains prior art information. UTILITY MODEL CONTENT

[0007] Therefore, it is necessary to provide a gear box for intelligent closestool, intelligent closestool cover and intelligent closestool for the above problems.

[0008] A gear box for intelligent closestool, comprising:

[0009] A housing;

[0010] A drive member provided in the housing;

[0011] A driving gear provided in the housing and capable of rotating under the driving of the driving shaft of the drive member;

[0012] A planet carrier rotatably provided in the housing;

[0013] A first clutch gear rotatably provided on the planet carrier and engaged with the driving gear;

[0014] A second clutch gear is rotationally arranged on the carrier and engaged with the driving gear, and the first clutch gear and the second clutch gear are arranged in a circumferential direction of the driving gear.

[0015] A transmission assembly is arranged in the housing; and

[0016] An output shaft is connected with the transmission assembly and can rotate under the driving of the transmission assembly, and the output shaft is used to be connected with a cover and / or a seat ring to drive the cover and / or the seat ring to turn over.

[0017] When the driving member is started, the first clutch gear and the second clutch gear can rotate around the outer circumferential surface of the driving gear under the driving of the driving gear, and the carrier can rotate to a first position and a second position under the driving of the first clutch gear and the second clutch gear; in the first position, the second clutch gear is separated from the transmission assembly, and the first clutch gear is engaged with the transmission assembly to drive the output shaft to rotate in a first rotation direction; in the second position, the first clutch gear is separated from the transmission assembly, and the second clutch gear is engaged with the transmission assembly to drive the output shaft to rotate in a second rotation direction; the first rotation direction is opposite to the second rotation direction.

[0018] The gear box for the intelligent toilet can achieve the following beneficial effects: when the driving member is started, in the first position, the second clutch gear is separated from the transmission assembly, and the first clutch gear is engaged with the transmission assembly to drive the output shaft to rotate in a first rotation direction; in the second position, the first clutch gear is separated from the transmission assembly, and the second clutch gear is engaged with the transmission assembly to drive the output shaft to rotate in a second rotation direction. Through the disengagement of the first clutch gear and the second clutch gear, the gear box can drive the output shaft to rotate in the first rotation direction and the second rotation direction, so as to realize the forward and reverse rotation of the cover and / or the seat ring, and meet the opening and closing requirements of the intelligent toilet cover.

[0019] In some embodiments, the gear box for the intelligent toilet further comprises a reset member arranged in the housing and connected to the planet carrier. When the driving member stops, the planet carrier is capable of being reset to rotate to a third position under the action of the reset member. In the third position, the first clutch gear and the second clutch gear are both separated from the transmission assembly, and the output shaft is capable of freely rotating under the driving of the lid and / or the seat ring. When the driving member stops, the reset member can automatically reset the planet carrier to rotate to the third position.

That is, in the third position, the first clutch gear and the second clutch gear are separated from the transmission assembly, and the output shaft can freely rotate. This allows the user to easily manually operate the lid and / or the seat ring without having to overcome the resistance caused by the driving member or the reset member, thereby improving the user's experience. It can be understood that when the gear box encounters resistance or overload, the driving member can stop in time, and the reset member can quickly reset the planet carrier to the third position, so that the clutch gear is separated from the transmission assembly, avoiding damage to the internal parts of the gear box due to overload, and enhancing the safety and durability of the system.

In the first position, the second clutch gear is separated from the transmission assembly, the first clutch gear is engaged with the transmission assembly, and the output shaft is driven to rotate in a first rotation direction. In the second position, the first clutch gear is separated from the transmission assembly, the second clutch gear is engaged with the transmission assembly, and the output shaft is driven to rotate in a second rotation direction. When the driving member is stopped, the planet carrier is reset and rotated to the third position under the elastic force of the reset torsion spring.

Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0046] Please see Figures 1 to 8In some embodiments, this application provides a gearbox 14 for a smart toilet, which includes a housing 100, a drive unit 200, a drive gear 300, a planetary carrier 400, a first clutch gear 510, a second clutch gear 520, a transmission assembly 600, and an output shaft 700. The driving member 200 is disposed in the housing 100; the driving gear 300 is disposed inside the housing 100 and can rotate under the drive of the driving shaft of the driving member; the planetary carrier 400 is rotatably disposed inside the housing 100; the first clutch gear 510 is rotatably disposed on the planetary carrier 400 and meshes with the driving gear 300; the second clutch gear 520 is rotatably disposed on the planetary carrier 400 and meshes with the driving gear 300, the first clutch gear 510 and the second clutch gear 520 are spaced apart along the circumference of the driving gear 300; the transmission assembly 600 is disposed inside the housing 100; the output shaft 700 is connected to the transmission assembly 600 and can rotate under the drive of the transmission assembly 600, the output shaft 700 is used to connect with the flip cover 12 and / or the seat ring 13 to drive the flip cover 12 and / or the seat ring 13 to flip.

[0047] When the drive unit 200 is activated, the first clutch gear 510 and the second clutch gear 520 can rotate around the outer circumference of the drive gear 300 under the drive of the drive gear 300, and the planetary carrier 400 can rotate to a first position and a second position under the drive of the first clutch gear 510 and the second clutch gear 520. Figure 7 As shown, in the first position, the second clutch gear 520 disengages from the transmission assembly 600, and the first clutch gear 510 engages with the transmission assembly 600 to drive the output shaft 700 to rotate in the first rotation direction; Figure 8 As shown, in the second position, the first clutch gear 510 is disengaged from the transmission assembly 600, and the second clutch gear 520 is engaged with the transmission assembly 600 to drive the output shaft 700 to rotate in the second rotation direction; the first rotation direction is opposite to the second rotation direction.

[0048] The gearbox 14 for a smart toilet described in this application can achieve at least the following beneficial effects: when the drive unit 200 is activated, such as Figure 7 As shown, in the first position, the second clutch gear 520 disengages from the transmission assembly 600, and the first clutch gear 510 engages with the transmission assembly 600 to drive the output shaft 700 to rotate in the first rotation direction; as Figure 8As shown, in the second position, the first clutch gear 510 disengages from the transmission assembly 600, and the second clutch gear 520 engages with the transmission assembly 600 to drive the output shaft 700 to rotate in the second rotation direction. Through the engagement and disengagement of the first clutch gear 510 and the second clutch gear 520, the gearbox 14 can drive the output shaft 700 to rotate in the first rotation direction and the second rotation direction, thereby realizing the forward and reverse operation of the flip cover 12 and / or the seat ring 13, meeting the opening and closing requirements of the smart toilet seat 10.

[0049] like Figure 4 , Figure 5 and Figure 9 As shown, in some embodiments, the gearbox 14 for the smart toilet further includes a reset member 800 disposed within the housing 100 and connected to the planetary carrier 400. When the drive member 200 stops, the planetary carrier 400 can be reset and rotated to a third position under the action of the reset member 800. In the third position, both the first clutch gear 510 and the second clutch gear 520 are disengaged from the transmission assembly 600, and the output shaft 700 can rotate freely under the drive of the flip cover 12 and / or the seat ring 13. When the drive member 200 stops, the reset member 800 can automatically reset and rotate the planetary carrier 400 to the third position. In the third position, both the first clutch gear 510 and the second clutch gear 520 are disengaged from the transmission assembly 600, ensuring that the output shaft 700 is in a free state, that is, in the third position, the first clutch gear 510 and the second clutch gear 520 are disengaged from the transmission assembly 600, and the output shaft 700 can rotate freely. This allows users to easily operate the flip cover 12 and / or seat ring 13 manually without overcoming the resistance from the drive unit 200 or the reset unit 800, thus improving the user experience. Understandably, when the gearbox 14 encounters resistance or overload, the drive unit 200 can stop promptly, and the reset unit 800 can quickly reset the planetary carrier 400 to the third position, disengaging the clutch gear from the transmission assembly 600. This prevents damage to internal components of the gearbox 14 due to overload, enhancing the system's safety and durability.

[0050] like Figure 5 and Figure 9As shown, in some embodiments, the planetary carrier 400 includes a support plate 410 and a support shaft 420 connected to the support plate 410. The first clutch gear 510 and the second clutch gear 520 are both rotatably connected to the support plate 410. The axial direction of the support shaft 420 is parallel to the axial direction of the first clutch gear 510 and the second clutch gear 520. The reset member 800 is a reset torsion spring, which is sleeved on the support shaft 420. One end of the reset torsion spring is fixed to the planetary carrier 400, and the other end is fixed to the housing 100. When the drive member 200 is started, the planetary carrier 400 can overcome the elastic force of the reset member 800 and rotate to the first position and the second position under the drive of the first clutch gear 510 and the second clutch gear 520. When the drive member 200 stops, the planetary carrier 400 can reset and rotate to the third position under the elastic force of the reset member 800. The planetary carrier 400 includes a support plate 410 for supporting and fixing the first clutch gear 510 and the second clutch gear 520. The design of the support plate 410 allows both the first clutch gear 510 and the second clutch gear 520 to rotate stably around their respective axes. The planetary carrier 400 also includes a support shaft 420 connected to the support plate 410. The axial direction of the support shaft 420 is parallel to the axial directions of the first clutch gear 510 and the second clutch gear 520, ensuring that the clutch gears maintain a stable motion trajectory during rotation. The reset element 800 is a reset torsion spring, which has a simple structure and is easy to install. The reset torsion spring is sleeved on the support shaft 420 and can achieve the reset function of the planetary carrier 400 through its own elastic force. When the drive element 200 is started, the drive gear 300 drives the first clutch gear 510 and the second clutch gear 520 to rotate. Driven by the first clutch gear 510 and the second clutch gear 520, the planetary carrier 400 overcomes the elastic force of the reset torsion spring and rotates to the first position or the second position. In the first position, the second clutch gear 520 disengages from the transmission assembly 600, while the first clutch gear 510 engages with it, driving the output shaft 700 to rotate in the first rotation direction. In the second position, the first clutch gear 510 disengages from the transmission assembly 600, while the second clutch gear 520 engages with it, driving the output shaft 700 to rotate in the second rotation direction. When the drive unit 200 stops, the planetary carrier 400 returns to its original position under the force of the return torsion spring. In the third position, both the first clutch gear 510 and the second clutch gear 520 disengage from the transmission assembly 600, the output shaft 700 is in a free state, and the user can easily manually operate the flip cover 12 and / or the seat ring 13.

[0051] like Figure 5As shown, in some embodiments, the support shaft 420 passes through and is fixed to the support plate 410. One end of the drive gear 300 has a limiting hole 330, and one end of the support shaft 420 is rotatably inserted into the limiting hole 330. The other end of the support shaft 420 is rotatably connected to the housing 100. This design allows the support shaft 420 to stably support the planetary carrier 400 and its clutch gear, ensuring stability during rotation. The other end of the support shaft 420 is rotatably connected to the housing 100, and the support shaft 420 is connected to the housing 100 via a bearing or bushing to reduce friction and ensure smooth rotation of the support shaft 420. A limiting hole 330 is formed at one end of the drive gear 300, and one end of the support shaft 420 is rotatably inserted into the limiting hole 330. The design of the limiting hole 330 allows the support shaft 420 to rotate freely within the drive gear 300, while restricting the radial displacement of the support shaft 420, ensuring its coaxiality with the drive gear 300. The diameter of the limiting hole 330 can be designed to be slightly larger than the diameter of the support shaft 420 to ensure that the support shaft 420 can rotate freely within the limiting hole 330 while restricting its radial displacement.

[0052] like Figure 9 As shown, in some embodiments, the housing 100 is provided with a limiting groove 110, the other end of the support shaft 420 is rotatably inserted into the limiting groove 110, the support plate 410 is provided with a fixing hole 413, one end of the reset torsion spring is fixedly inserted into the fixing hole 413, the reset torsion spring is located in the limiting groove 110 and the other end of the reset torsion spring is fixed to the limiting groove 110. The housing 100 is provided with a limiting groove 110 for accommodating the other end of the support shaft 420 and the reset torsion spring. The design of the limiting groove 110 not only provides rotational support for the support shaft 420, but also provides space for the installation and fixing of the reset torsion spring. The support plate 410 is provided with a fixing hole 413 for fixing one end of the reset torsion spring. The design of the fixing hole 413 allows the reset torsion spring to be firmly fixed on the support plate 410, ensuring that it can provide a stable reset force when the planetary carrier 400 rotates. One end of the reset torsion spring is fixedly inserted into the fixing hole 413, and the other end is fixed to the limiting groove 110. The reset torsion spring is located in the limiting groove 110, which can make full use of the space of the housing 100.

[0053] like Figure 5As shown, in some embodiments, the support plate 410 has a first rotating hole 411 and a second rotating hole 412 spaced apart from each other. A first rotating shaft 511 is rotatably inserted into the first rotating hole 411 and is connected to the first clutch gear 510. A second rotating shaft 521 is rotatably inserted into the second rotating hole 412 and is connected to the second clutch gear 520. The first rotating hole 411 and the second rotating hole 412 are used to accommodate the first rotating shaft 511 and the second rotating shaft 521 respectively, and to provide rotational support for the clutch gear. The size design of the first rotating hole 411 and the second rotating hole 412 allows the first rotating shaft 511 and the second rotating shaft 521 to rotate freely within the holes, while restricting their radial displacement, ensuring the coaxiality of the clutch gear and the support plate 410.

[0054] like Figure 8 and Figure 9 As shown, in some embodiments, the gearbox 14 for the smart toilet further includes two first retaining rings 512. One end of the first rotating shaft 511 passes through the first clutch gear 510 and is fixed with one of the first retaining rings 512 to limit the axial movement of the first clutch gear 510 on the first rotating shaft 511. The other end of the first rotating shaft 511 passes through the first rotating hole 411 and is fixed with the other first retaining ring 512 to limit the axial movement of the first rotating shaft 511 on the first rotating hole 411. The first clutch gear 510 is rotatably clamped between one of the first retaining rings 512 and the support plate 410. The two first retaining rings 512 are respectively installed at both ends of the first rotating shaft 511 to limit the axial movement of the first rotating shaft 511 and the first clutch gear 510, preventing axial displacement. The first clutch gear 510 is rotatably clamped between one of the first retaining rings 512 and the support plate 410 to ensure stability during rotation and to avoid axial displacement, thus preventing malfunctions caused by axial displacement. The first snap ring 512 has a simple installation method, facilitating assembly and maintenance and reducing production costs. It should be noted that the first snap ring 512 can be fixed to both ends of the first rotating shaft 511 by snap-fit ​​or press-fit to ensure its firmness. One end of the first rotating shaft 511 can be fixed to the first clutch gear 510 by keyway, spline, or threaded connection to ensure it can drive the first clutch gear 510 to rotate. The gap between the first clutch gear 510 and the support plate 410 should be slightly larger than the thickness of the first snap ring 512 to ensure that the first clutch gear 510 can rotate freely while preventing axial displacement.

[0055] like Figure 8 and Figure 9As shown, in some embodiments, the gearbox 14 for the smart toilet further includes two second retaining rings 522. One end of the second rotating shaft 521 passes through the second clutch gear 520 and is fixed with one of the second retaining rings 522 to limit the axial movement of the second clutch gear 520 on the second rotating shaft 521. The other end of the second rotating shaft 521 passes through the second rotating hole 412 and is fixed with the other second retaining ring 522 to limit the axial movement of the second rotating shaft 521 on the second rotating hole 412. The second clutch gear 520 is rotatably clamped between one of the second retaining rings 522 and the support plate 410. The two second retaining rings 522 are respectively installed at both ends of the second rotating shaft 521 to limit the axial movement of the second rotating shaft 521 and the second clutch gear 520, preventing axial displacement. The second clutch gear 520 is rotatably clamped between one of the second retaining rings 522 and the support plate 410 to ensure stability during rotation and to avoid axial displacement, thus preventing malfunctions caused by axial displacement. The second snap ring 522 has a simple installation method, facilitating assembly and maintenance and reducing production costs. It should be noted that the second snap ring 522 can be fixed to both ends of the second rotating shaft 521 by snap-fit ​​or press-fit to ensure its firmness. One end of the second rotating shaft 521 can be fixed to the second clutch gear 520 by keyway, spline, or threaded connection to ensure it can drive the second clutch gear 520 to rotate. The gap between the second clutch gear 520 and the support plate 410 should be slightly larger than the thickness of the second snap ring 522 to ensure that the second clutch gear 520 can rotate freely while preventing axial displacement.

[0056] like Figure 2 As shown, in some embodiments, the driving gear 300 includes a first driving gear 310 and a second driving gear 320 that are at least partially meshed.

The worm gear 900 meshes with the first driving gear 310, and the second driving gear 320 meshes with the first clutch gear 510 and the second clutch gear 520. The first driving gear 310 meshes with the worm gear 900 of the motor to transmit the rotational motion of the motor to the second driving gear 320. The second driving gear 320 meshes with the first clutch gear 510 and the second clutch gear 520 to transmit power to the clutch gears.

[0057] like Figure 2As shown, in some embodiments, the transmission assembly 600 includes a first transmission gear 610 and a second transmission gear 620 meshing with each other. The second transmission gear 620 can drive the output shaft 700 to rotate.

In the second position, the first transmission gear 610 disengages from the first clutch gear 510 and meshes with the second clutch gear 520. When the planetary carrier 400 is in the first position, the first clutch gear 510 meshes with the first transmission gear 610, and the second clutch gear 520 disengages from the first transmission gear 610. The driving gear 300 drives the first clutch gear 510 to rotate via the second driving gear 320. The first clutch gear 510 drives the first transmission gear 610 to rotate, and the first transmission gear 610 drives the second transmission gear 620 to rotate. The second transmission gear 620 drives the output shaft 700 to rotate in the forward direction. In the second position, the planetary carrier 400 is in the first position, with the first clutch gear 510 disengaged from the first drive gear 610, and the second clutch gear 520 engaged with the first drive gear 610. The driving gear 300 drives the second clutch gear 520 to rotate via the second driving gear 320, which in turn drives the first drive gear 610 to rotate. The first drive gear 610 then drives the second drive gear 620 to rotate, and the second drive gear 620 drives the output shaft 700 to rotate in the opposite direction. In the third position, both the first clutch gear 510 and the second clutch gear 520 are disengaged from the first drive gear 610.
