Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

As shown in fig. 1 and 2, in some embodiments, the present application provides an automatic flip mechanism 10 that includes a stationary support 11 and a seat 12. The seat 12 is hinged to the fixed support 11, the seat 12 rotates relative to the fixed support 11 to have an open position and a locking position, and the rotation direction of the seat 12 when rotating from the open position to the locking position is a reverse direction. As shown by arrow N1 in fig. 3 and 11, the direction of rotation is the forward rotation direction, and the opposite direction is the reverse rotation direction. It is understood that the direction of rotation when the seat 12 is lifted is the forward rotation direction.

When the user sits down and presses the seat 12 against the seat body 21, the seat 12 is located at the sitting position. In some cases, the seat 12 in the open position is rotated through an angle of 90 ° relative to the seat 12 in the seated position. The seat 12 passes through the locked position during rotation from the open position to the seated position. In some embodiments, the seat 12 in the locked position is rotated through an angle of 5 ° relative to the seat 12 in the seated position.

Further, in some embodiments, the automatic flip mechanism 10 further includes a first elastic member (not shown in the drawings), which acts between the fixed support 11 and the seat 12, and is used to provide an elastic force for forward rotation of the seat 12 relative to the fixed support 11. The seat 12 can be automatically lifted up under the action of the first elastic member. The first elastic member may be a torsion spring.

As shown in fig. 1 to 4, the fixed support 11 is provided with a rotation stopper 111. As shown in fig. 5 and 6, the seat 12 is provided with a blocking portion 1231. The rotation stop member 111 is blocked in the forward rotation direction of the blocking portion 1231 when the seat 12 rotates forward to the open position relative to the fixed support 11, so that the seat 12 can only rotate forward to the open position relative to the fixed support 11, and the seat 12 is prevented from being lifted up to an excessive angle to strike the rear toilet cover or other structures.

As shown in fig. 3, a locking component 13 is further disposed between the fixed support 11 and the seat 12, the locking component 13 has a locking state, and when the seat 12 is reversed to a locking position relative to the fixed support 11, the locking component 13 can be switched to the locking state to prevent the seat 12 from rotating forward relative to the fixed support 11.

The first elastic member is used to drive the seat 12 to rotate forward relative to the fixed support 11, thereby eliminating the need for circuit conditions in the use environment. The seat 12 driven by the first elastic member cannot control the seat 12 to stop rotating at any time by the start and stop of the driving member like the seat 12 driven by the motor, so the rotation stopper 111 and the locking assembly 13 are further provided. The rotation stopping piece 111 and the blocking part 1231 are matched to accurately limit the seat ring 12 at the opening position, so that the phenomenon that the seat ring 12 is excessively large in positive angle and collides with other structures is effectively avoided. The locking assembly 13 can lock the seat ring 12 in the locking position, so that a user can sit conveniently. Specifically, the user can manually drive the seat 12 to reverse to the locking position, and when the seat 12 rotates to the locking position, the locking assembly 13 overcomes the elastic force of the first elastic member to limit the seat 12 to the locking position. At this time, after the user removes the force for driving the seat ring 12 to rotate reversely, the seat ring 12 does not rotate forward even if the first elastic member exists, so that the seat is convenient.

First, the specific structure of stop rotor 111 and blocking portion 1231 in some embodiments is described by way of example:

the seat 12 is hinged to the fixed support 11 by a hinge shaft (not shown), and the rotation stopper 111 protrudes outside the fixed support 11 in a direction intersecting an axial direction of the hinge shaft. Referring to fig. 5 and 6, a rotation stopping groove 123 is provided at a position facing the rotation stopping member 111 when the seat 12 rotates. The end of the rotation stop 111 can slide in the rotation stop groove 123 in the reverse direction when the seat 12 rotates relative to the fixed mount 11. As shown in fig. 6, the blocking part 1231 includes a blocking wall of the rotation stopping groove 123. Returning to fig. 4, when the seat 12 is rotated reversely to the locking position, the rotation stopper 111 is blocked in the forward rotation direction of the blocking wall.

Fig. 3 shows a cross-sectional view of the automatic flip mechanism 10 with the seat 12 in the locked position, where the rotation stop 111 is not in the rotation stop slot 123 provided on the seat 12. Taking the angle shown in fig. 4 as an example, when the seat 12 rotates clockwise with respect to the fixed support 11, the rotation stopping groove 123 gradually approaches the rotation stopping piece 111. As the rotation angle of the seat 12 increases, the end of the rotation stopper 111 gradually slides into the rotation stopper 123 until the rotation stopper 111 abuts against the blocking wall of the rotation stopper 123.

The portion of the groove wall of the rotation stopping groove 123 that contacts the end surface of the rotation stopping piece 111 when the rotation stopping piece 111 slides in the rotation stopping groove 123 is defined as a side wall, and the bottom wall of the rotation stopping groove 123 is blocked.

In particular, in some embodiments, as shown in fig. 5 and 6, the seat 12 includes a ring body 121 and two lugs 122 spaced apart in an axial direction of the hinge shaft, and both the lugs 122 are connected to the ring body 121. As shown in fig. 1 and 2, the fixing support 11 is located between two of the lugs 122. Each of the lugs 122 is hinged to the fixed support 11 by means of the hinge shaft, and the elastic member acts between the lug 122 and the fixed support 11.

As shown in fig. 5 and 6, the rotation stopping groove 123 is formed on the surface of the ring body 121 facing the fixing support 11. As shown in fig. 1 and 2, the windward side of the ring body 121 is a seating surface 1211 when the ring body 121 rotates forward, and the rotation stopping groove 123 penetrates the seating surface 1211 of the ring body 121 in the thickness direction of the ring body 121, and a cut-in opening is formed in the seating surface 1211.

Referring back to fig. 4, when the seat 12 rotates forward with respect to the fixed mount 11, the end of the rotation stopper 111 slides into the rotation stopper groove 123 from the cut-in. As the positive angle of the seat 12 increases, the end of the rotation stopper 111 gradually approaches the blocking wall until abutting against the blocking wall. After the rotation stopper 111 abuts against the blocking wall, the seat 12 cannot continue to rotate forward with respect to the fixed mount 11.

Further specifically, in one embodiment, as shown in fig. 3 and 4, the rotation stopper 111 protrudes from the fixed mount 11 in a direction perpendicular to the axial direction of the hinge shaft. After the end of the rotation stopper 111 enters the rotation stopper groove 123 from the cut-in, the direction in which the rotation stopper 111 protrudes from the fixing support 11 intersects with the depth direction of the rotation stopper groove 123. For example, under the angle shown in fig. 4, assuming that the fixed support 11 is stationary and the seat 12 rotates forward, when the seat 12 rotates forward to the vertical direction, the depth direction of the rotation stopping groove 123 is the horizontal direction, and at this time, the end of the rotation stopping member 111 is located in the rotation stopping groove 123, and the direction in which the end of the rotation stopping member 111 protrudes from the fixed support 11 is the longitudinal direction.

In some embodiments, as shown in fig. 3 and 4, the rotation stopper 111 is slidably inserted in the fixed support 11 in a first direction. The direction in which the rotation stopper 111 protrudes from the fixed mount 11 is parallel to the first direction. The direction indicated by the arrow N2 in fig. 4 is the second direction. The rotation stop 111 corresponds to a latch slidably inserted in the fixed support 11.

A second elastic member 1112 is disposed between the rotation stopping member 111 and the fixed support 11, and the second elastic member 1112 is configured to provide an elastic force for the rotation stopping member 111 to extend out of the fixed support 11 along the first direction. At the angle shown in fig. 4, the rotation stopper 111 protrudes outward from the fixed mount 11 in the first direction as upward. And the rotation stopper 111 protrudes at one end of the fixed mount 11 for blocking in the forward rotation direction of the blocking part 1231 when the seat 12 is in the locking position.

When the rotation stopper 111 gradually enters the rotation stopper groove 123 during rotation of the seat ring 12, if the rotation stopper 111 applies a thrust force in the first direction to the side wall of the rotation stopper groove 123, the rotation stopper 111 slides a small distance into the fixed mount 11. The rotation stopper 111 is floatable relative to the fixed mount 11 in the first direction in a certain range so that the seat 12 can be smoothly rotated to the open position.

In order to limit the protruding height of the rotation stop member 111 protruding out of the fixed support 11, in some cases, as shown in fig. 4, a limiting protrusion 1111 is provided on the rotation stop member 111, and the fixed support 11 has a mating portion (not shown) that blocks in a direction in which the limiting protrusion 1111 protrudes out of the fixed support 11 in the first direction. When the rotation stopper 111 is not in contact with the seat 12, the rotation stopper 111 slides to a position where the limit projection 1111 abuts against the mating portion with respect to the fixed mount 11 by the second elastic member 1112. When the seat ring 12 rotates to the rotation stopping piece 111 and enters the rotation stopping groove 123, the rotation stopping piece 111 can be pressed into the fixed support 11 by the seat ring 12, at the moment, the rotation stopping piece 111 can overcome the elasticity of the second elastic piece 1112 to slide into the fixed support 11, and at the moment, the limit protrusions 1111 are separated from the matching parts and are arranged at intervals.

As shown in fig. 4, in some embodiments, the second elastic member 1112 is a compression spring that acts directly or indirectly between the fixed support 11 and the rotation stopper 111. For example, the rotation stopping member 111 may be inserted into the second elastic member 1112, one end of the second elastic member 1112 abuts against the limit protrusion 1111, and the other end of the second elastic member 1112 acts on the fixing support 11, so that the rotation stopping member 111 provides an elastic force extending outward of the fixing support 11 in the first direction.

Next, the locking assembly 13 and its associated structure in some embodiments are described further below:

for example, in some embodiments, as shown in fig. 4, the locking assembly 13 includes a slider 131 and a first hook 132 disposed on the seat 12, and a second hook 1311 is disposed on the slider 131.

The sliding block 131 is slidably disposed on the fixed support 11, the sliding block 131 can slide between a forward position and a backward position relative to the fixed support 11, and when the sliding block 131 is located in the forward position and the seat 12 is located in the locking position, the first hook 132 hooks on the second hook 1311, and the locking assembly 13 is in a locking state. So that the seat 12 cannot rotate forward with respect to the fixed support 11. The state shown in fig. 4 is the state when the 12 seat is in the locked position.

The second hook 1311 is disengaged from the first hook 132 when the slider 131 is in the retracted position, and the locking assembly 13 is in an unlocked state. So that the seat ring 12 can rotate forward and backward relative to the fixed support 11.

After the user manually rotates the seat 12 to the locking position, the manual force applied to the seat 12 is released, and the seat 12 is not rotated forward relative to the fixed mount 11 but is maintained in the locking position. The sliding block 131 can also slide to the retreating position, so after the toilet 20 is used, the locking assembly 13 can be adjusted to the unlocking state, and the seat 12 can be rotated to the opening position again under the action of the first elastic member.

Alternatively, in other embodiments, the locking assembly 13 may be of other configurations, so long as it has the aforementioned locked state.

The manner in which the locking assembly 13 is adjusted to the unlocked state is varied, such as: the locking assembly 13 may be manually adjusted to the unlocked state or the locking assembly 13 may be triggered to switch states by other actions. For example, as the seat 12 continues to rotate from the locked position to the seated position, the seat 12 may trigger the locking assembly 13 such that the locking assembly 13 switches to the unlocked state.

In some embodiments, as shown in fig. 4, the locking assembly 13 further comprises a third elastic member 133, the third elastic member 133 acting between the slider 131 and the fixed support 11 for providing an elastic force for the slider 131 to slide from the retracted position to the advanced position. The slider 131 always has a tendency to remain in the advanced position under the action of the third elastic member 133. The third elastic member 133 provides the slider 131 with a force directed leftward at an angle as shown in fig. 4.

Further, in some embodiments, as shown in fig. 5 and 6, an unlocking trigger 124 is further provided on the seat 12. As shown in fig. 7 to 9, the slider 131 is provided with a pushing member 1312. Referring to fig. 3 and 4, after the seat 12 continues to rotate reversely relative to the fixed support 11 from the locking position by a predetermined angle, the first hook 132 is disengaged from the second hook 1311, and the unlocking trigger 124 acts on the pushing member 1312 when the seat 12 continues to rotate reversely, so as to provide a force for the pushing member 1312 against the elastic force of the third elastic member 133, so that the slider 131 moves to the retreating position. Here, the seat 12 continues to rotate in reverse, which corresponds to a trigger action that can switch the slider 131 of the locking assembly 13 to the retracted position, in the unlocked state.

Further, in some embodiments, at least one of the contact surfaces of the unlocking trigger 124 and the pushing member 1312 when they interact is a guiding inclined surface 1241, and the guiding direction of the guiding inclined surface 1241 intersects with the deformation direction of the third elastic member 133.

For example, in one embodiment, as shown in fig. 5 and 6, the surface of the unlocking trigger 124 that contacts the pushing member 1312 is the guiding inclined surface 1241. As shown in fig. 7 to 9, the surface of the pushing member 1312 that contacts the unlocking trigger 124 is the guide inclined surface 1241. The guiding direction of the guiding inclined plane 1241 intersects with the sliding direction of the sliding block 131 relative to the fixed support 11. When the seat 12 continues to rotate reversely from the lock position, the unlock trigger 124 abuts against the push piece 1312, so that the slider 131 slides to the retreating position with respect to the fixed mount 11.

In order to ensure that the slider 131 can be maintained in the retracted position when the seat 12 starts to rotate forward from the seated position so that the seat 12 can rotate forward to the open position, a switch assembly 14 may be further provided.

As shown in fig. 7 to 9, the fixed support 11 is further provided with a switching member 14, and the switching member 14 has a slip-preventing state, and the switching member 14 in the slip-preventing state is used for preventing the sliding block 131 located at the retracted position from sliding toward the advanced position.

Still further, in some embodiments, the switching assembly 14 has a released state, the seat 12 in the open position provides the rotation stopping member 111 with a pressing force against the second elastic member 1112, and the rotation stopping member 111 slides into the fixed support 11 under the pressing force and triggers the switching assembly 14 to switch to the released state, and the sliding block 131 is capable of moving relative to the switching assembly 14 in the released state from the retracted position to the advanced position.

It will be appreciated that the action of positively rotating the seat 12 to the open position can trigger the switching assembly 14 to switch to the released state by the detent 111, thereby ensuring that the locking assembly 13 can switch to the unlocked state after the seat 12 is positively rotated to the open position in preparation for the next time the seat 12 is reversely locked in the locked position.

In some embodiments, as shown in fig. 6, the seat 12 has a trigger inclined surface 1232, one end of the seat 12 extending out of the fixed support 11 during the forward rotation to the open position slides over the trigger inclined surface 1232, an acting point on the trigger inclined surface 1232 abutting against the rotation stopping member 111 is a mark point, and a distance between the mark point and a rotation axis of the seat 12 during the forward rotation of the seat 12 is gradually reduced, and the first direction is perpendicular to the rotation axis of the seat 12.

In some cases, the inclined surface 1232 is triggered to the side wall surface of the rotation groove 123. When the seat ring 12 rotates forward and the rotation stopper 111 slides in the rotation stopper groove 123, the rotation stopper 111 gradually presses and slides into the fixed mount 11.

When the user manually reverses the seat 12 to the locked position, the locking assembly 13 may be switched to the locked state, thereby locking the seat 12 in the locked position.

When the user sits, the seat 12 continues to reverse relative to the locking position, the seat 12 triggers the locking assembly 13 such that the locking assembly 13 is switched to the unlocked state, and the switching assembly 14 is switched to the anti-slip position such that the locking assembly 13 remains in the unlocked state. In this case, when the user walks away, the seat 12 is positively rotated to the open position by the first elastic member.

When the seat 12 rotates forward to the open position, the switching assembly 14 is triggered to switch to the release state by the rotation stopping member 111, the sliding block 131 can slide to the forward position without blocking of the switching assembly 14 under the action of the third elastic member 133, and the seat 12 can be locked again by the locking assembly 13 when rotating reversely to the locking position.

As shown in fig. 4, when the seat 12 is reversed to the locking position, the first hook 132 on the seat 12 may press the second hook 1311 first, so that the sliding block 131 slides slightly in a direction tending to the retreating position against the elastic force of the third elastic member 133, after the first hook 132 presses and slides over the second hook 1311, the sliding block 131 returns to the advancing position under the action of the third elastic member 133, the first hook 132 and the second hook 1311 are hooked together, and the locking assembly 13 is in the locking state.

The states and positions of the respective moving parts are summarized as follows:

the seat 12 has an open position, a locked position, and a seated position;

the locking assembly 13 has a locked state and an unlocked state, the sliding block 131 has a forward position and a backward position, the sliding block 131 included in the locking assembly 13 in the locked state is located at the forward position, and the sliding block 131 included in the locking assembly 13 in the unlocked state is located at the backward position;

the switch assembly 14 has an anti-slip state and a release state.

Specifically, in some embodiments, as shown in fig. 7 to 10, the switching assembly 14 includes an elastic telescopic unit, one end of which is connected to the fixed support 11, the elastic telescopic unit includes a slip stopper 1411, and the slip stopper 1411 slides in a telescopic direction of the elastic telescopic unit with respect to the slider 131 when the elastic telescopic unit is deformed in a telescopic manner;

the elastic telescopic unit has a first deformation amount in the slip-stop state, and the slip-stop portion 1411 abuts against the slider 131 located at the backward position to prevent the slider 131 from sliding toward the forward position;

the elastic expansion unit has a second deformation amount when in a release state, the anti-slip part 1411 is staggered with the sliding block 131, and the second deformation amount is different from the first deformation amount;

The rotation stop member 111 can drive the elastic expansion unit to generate a second deformation when sliding into the fixed support 11.

The elastic expansion and contraction unit causes the switching assembly 14 to switch between the slip-resistant state and the release state by being deformed by expansion and contraction. The rotation stopping member 111 can trigger the elastic expansion unit to expand and deform when sliding into the fixed support 11, and the deformation amount is the second deformation amount.

When the seat ring 12 rotates forward to the opening position, the rotation stopping piece 111 provides a pressing force, the rotation stopping piece 111 overcomes the elastic force of the second elastic piece 1112 under the action of the pressing force to slide into the fixed support 11, and the rotation stopping piece 111 can drive the elastic telescopic unit to elastically deform in the sliding process, so that the position of the anti-sliding part 1411 is changed.

Specifically, a transmission structure may be disposed on the sliding path of the rotation stop member 111, and the transmission structure is used to apply a force to the elastic expansion unit, so that the elastic expansion unit is deformed by a second amount.

Alternatively, as shown in fig. 7, the sliding direction of the rotation stopper 111 with respect to the fixed support 11 is identical to the expansion and contraction deformation direction of the elastic expansion and contraction unit, and the end of the elastic expansion and contraction unit, which is not connected to the fixed support, is located on the sliding path of the rotation stopper 111 sliding into the fixed support 11. The rotation stopping piece 111 is pressed against the elastic telescopic unit when sliding into the fixed support 11, so that the elastic telescopic unit is subjected to telescopic deformation, and the deformation amount is the second deformation amount, so that the position of the sliding stopping portion 1411 is changed, and the sliding stopping portion 1411 is staggered with the sliding block 131. On the basis of this, the slider 131 can slide to the advanced position by the third elastic member 133.

In some embodiments, as shown in fig. 7 and 8, the slider 131 is provided with a through hole 1313 penetrating in a direction of expansion and contraction deformation of the elastic expansion and contraction unit, and the elastic expansion and contraction unit penetrates through the through hole 1313, and has one end connected to the fixed support 11 and the other end corresponding to the rotation stopper 111, and the second deformation amount is greater than the first deformation amount. As shown in fig. 9 and 10, the portion of the elastic expansion and contraction unit located in the through hole 1313 when the second deformation amount occurs is a thin rod section 1412, and the outer diameter of the slip stopper 1411 is larger than the outer diameter of the thin rod section 1412.

When the thin rod section 1412 is positioned in the through hole 1313, the slider 131 can slide toward the advanced position due to the small outer diameter of the thin rod section 1412, and the slider 131 is in the advanced position when the slider 131 slides until the wall of the through hole 1313 abuts the thin rod section 1412.

The outer diameter of the slip stopper 1411 is large, so that when the slip stopper 1411 is positioned in the through hole 1313, the movement of the slide 131 in the forward direction is restricted, and when the slip stopper 1411 contacts the wall of the through hole 1313, the slide 131 is positioned in the retracted position.

As shown in fig. 10, in some embodiments, the elastic telescopic unit includes a stepped boss 141 and a fourth elastic member 142, the fourth elastic member 142 acts between the stepped boss 141 and the fixed support 11, the stepped boss 141 includes a thin rod section 1412 and a slip stopper 1411, and the deformation direction of the fourth elastic member 142 is the telescopic deformation direction of the elastic telescopic unit. For example, in some embodiments, the deformation direction of the fourth elastic member 142 coincides with the sliding direction of the rotation stop member 111 with respect to the fixed support 11.

Further specifically, as shown in fig. 8, the bore 1313 includes a narrow bore through which the thin shank 1412 passes and a wide bore through which the limited slip 1411 passes, the limited slip 1411 having an outer diameter greater than the width of the narrow bore, the wide bore being located in the direction of advancement of the narrow bore.

The thin rod section 1412 is inserted in the narrow hole when the slider 131 is positioned in the advanced position, and the slip stopper 1411 is blocked under the slider 131 with a larger outer diameter, so that the elastic expansion and contraction unit is maintained in a state of a second deformation amount.

When the slider 131 is in the retracted position, the wide hole is opposed to the slip stopper 1411, the slip stopper 1411 slides into the wide hole, and the deformation amount of the elastic expansion and contraction unit becomes the first deformation amount.

The following describes the whole cycle of forward and reverse rotation of the seat 12 in detail:

state one: the seat 12 is in the open position, and the rotation stop 111 provides a force to the elastic telescopic unit, so that the elastic telescopic unit is deformed by a second amount, the thin rod section 1412 is inserted into the through hole 1313, the sliding stop 1411 is located outside the through hole 1313, and the sliding block 131 is located in the advanced position. The shoulder formed at the interface of slip stop 1411 and thin rod segment 1412 presses against slider 131. The slider 131 prevents the elastic expansion and contraction unit from changing to the state of the first deformation amount. In other words, the slider 131 located at the advanced position can prevent the elastic expansion and contraction unit from switching to the state of the first deformation amount.

State two: after the seat ring 12 reverses the urging force against the rotation stopper 111, the elastic expansion unit is maintained in a state of the second deformation amount by the slider 131. The seat 12 continues to reverse to the locked position, with the first hook 132 hooked with the second hook 1311, and the seat 12 held in the locked position.

State three: as the seat 12 continues to reverse from the locked position, the unlock trigger 124 contacts the push 1312, causing the slide 131 to slide toward the retracted position. After the sliding block 131 slides to the retreating position, on the one hand, the first hook 132 is separated from the second hook 1311, and on the other hand, after the shoulder pressed by the previous step is separated from the constraint of the sliding block 131, the elastic telescopic unit can be elastically deformed to be converted to a first deformation amount, and the anti-sliding part 1411 slides into the through hole 1313. So that the slider 131 can be maintained in the retreating position. After the user leaves the toilet 20, the seat 12 will rotate forward to the open position under the action of the first elastic member and return to the first state.

Still further, in some embodiments of the present application, there is provided a toilet 20, as shown in fig. 11, including a base 21 and the automatic flip mechanism 10 of any one of the above, wherein the fixed support 11 is mounted on the base 21.

By adopting the automatic flip mechanism 10 described in any of the above embodiments, the automatic flip function is realized without depending on the circuit environment, and the rotation stop member 111 and the blocking portion 1231 cooperate to accurately limit the seat 12 at the open position, so as to effectively avoid the excessive positive angle of the seat 12 from striking with other structures. The locking assembly 13 can lock the seat ring 12 in the locking position, so that a user can sit conveniently.
