Description

Technical Field

[0001] This utility model generally relates to the field of bathroom equipment technology, and more specifically, to a cover locking structure and a lifting mechanism having the same. Background Technology

[0002] When users clean the ceramic part of the toilet, they will find that the rear half of the ceramic end face is blocked by the fixed seat, creating a hard-to-clean area that is prone to mold and dust accumulation. This not only affects the overall appearance of the toilet but also poses a health threat due to bacterial growth. To thoroughly clean this area, users have to lift the smart seat. Therefore, the seat and the toilet base (ceramic part) need to be designed as a detachable structure to meet this cleaning need. However, with a detachable structure, it is difficult to maintain the height of the seat after it is raised, and the connection between the seat and the toilet base is less stable. The seat is prone to shaking and damage during use, or it may be lifted up during normal use, resulting in an unsatisfactory lifespan and performance.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] The present invention includes a series of simplified concepts, which will be further explained in detail in the detailed description section. This present invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] One of the main objectives of this utility model is to overcome at least one of the defects of the prior art and to provide a cover plate locking structure and a lifting mechanism having thereon.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] According to one aspect of the present invention, a cover plate locking structure is provided, comprising:

[0008] The toilet seat is either detachably and fixedly connected to the toilet base or movably connected to it.

[0009] The main support component is located on the toilet base under the cover plate, and the main support component is provided with a first guide structure;

[0010] At least one support member for supporting and / or connecting the cover plate, the support member being disposed on the first guide structure and slidable along the direction defined by the first guide structure;

[0011] Positioning element, which is located on the main bearing component to fix the bearing component in position before and / or after sliding.

[0012] According to one embodiment of the present invention, the main bearing component is provided with a second guide structure, and the positioning component is disposed on the second guide structure and can slide along the direction defined by the second guide structure. The sliding position of the positioning component includes at least a locked position and an unlocked position. In the locked position, the position of the bearing component is fixed by the positioning component, and in the unlocked position, the positioning component makes way for the bearing component.

[0013] According to one embodiment of the present invention, the support member is provided with at least one positioning part for cooperating with the positioning member. In the locked position, the positioning member is close to the positioning part and cooperates with the positioning part to fix the relative position of the support member and the main support member. In the unlocked position, the positioning member is away from the positioning part.

[0014] According to one embodiment of the present invention, the first guide structure includes a first guide channel, the support member is disposed in the first guide channel, and the outer periphery of the first guide channel is provided with a threaded portion for locking to the toilet base.

[0015] According to one embodiment of the present invention, a reset member is provided between the positioning member and the main bearing member, and the reset member is used to drive the positioning member to automatically return to the locked position or the unlocked position.

[0016] According to one embodiment of the present invention, the positioning member is composed of a first positioning rod and a second positioning rod spliced ​​together, and the first positioning rod and the second positioning rod are used to fix the positions of two independent support members respectively.

[0017] According to one embodiment of the present invention, the sliding direction of the support member is perpendicular to the sliding direction of the positioning member, and the positioning part is a locking groove provided on the support member. In the locked position, one end of the positioning member extends into the locking groove, and in the unlocked position, the positioning member exits the locking groove.

[0018] According to one embodiment of the present invention, a limiting member is further included. The limiting member moves between a limiting position and a yielding position. When the limiting member is in the limiting position, it presses against one end of the positioning member to limit the positioning member to the locking position. When the limiting member is in the yielding position, it yields to the positioning member, allowing the positioning member to move to the unlocking position.

[0019] According to another aspect of this disclosure, a lifting mechanism is provided, comprising: a cover plate locking structure as claimed in claim , the lifting mechanism including a rising portion for lifting the cover plate, the limiting member being disposed on the rising portion or integrally formed with the rising portion.

[0020] According to one embodiment of the present invention, there is a free travel area between the limiting member and the cover plate. When the limiting member is in the yielding position, it enters the free travel area. The limiting member is provided with a relief part for unlocking the positioning member so that it can move to the unlocking position.

[0021] As can be seen from the above technical solution, the advantages and positive effects of this utility model are as follows:

[0022] This utility model's lid locking structure uses a detachable, installable main support component as its core. A flexibly controllable positioning component locks and positions the sliding support component on the main support component, ensuring the lid connected to the support component remains at a fixed height. This solves the problems of difficulty in maintaining a fixed height after the lid is raised, poor stability of the connection between the lid and the toilet base hindering cleaning, and the lid not locking properly after being raised, making it easy to lift during normal use. Furthermore, this lid locking structure can also be used in conjunction with a lifting mechanism. By placing a limiting component that restricts the locking position of the positioning component on the rising part of the lifting mechanism, it achieves unlocking when the lid is raised and locking after being lowered, preventing the lid from being easily lifted by the user during normal use.

[0023] This invention aims to provide a more convenient and robust intelligent toilet seat lifting structure. When the toilet needs to be cleaned, the intelligent toilet seat can be lifted to make way for the ceramic end face, thus greatly facilitating daily toilet cleaning. The lifting structure includes a positioning component driven by a toothed column. As the toothed column moves up and down, the toilet seat is unlocked and locked, allowing for easy one-click installation and removal. Attached Figure Description

[0042] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0043] like Figures 1-6 As shown, this embodiment provides a toilet seat locking structure, including: a toilet seat 100, which is detachably and fixedly connected or movably connected to a toilet base 200; a supporting main component 300, disposed on the toilet base 200 below the toilet seat 100. In this embodiment, the supporting main component 300 is disposed on the rib plate of the toilet base 200, and the supporting main component 300 is provided with a first guide structure 310; at least one supporting member 400, which is used to support and / or connect the toilet seat 100, and the supporting member 400 is disposed on the first guide structure 310 and can slide along the direction defined by the first guide structure 310; and a positioning member 500, which is disposed on the supporting main component 300 to fix the position of the supporting member 400 before and / or after sliding. It is understood that, under normal conditions, the toilet seat 100 is installed on the toilet base 200, and the detachable connection methods between the toilet seat 100 and the toilet base 200 include insertion, snap-fit, magnetic attraction, bolt locking, etc. The movable connection method can be a guide rail structure, hinge structure, etc., located between the two. Therefore, when needed, the cover plate 100 can be temporarily lifted and separated from the toilet base 200. The cover plate 100 can be used to cover the internal structure of the toilet, including but not limited to covering the toilet bowl. The cover plate 100 can also be the carrier of the main functional components of the smart toilet, including but not limited to functional components such as flip-top, close-top, flushing, bidet, heating, and drying. At the same time, the control device electrically connected to the motor 720 and controlling the operation of the motor 720 can also be located therein, so that the motor 720 can be run manually or remotely controlled to perform forward or reverse operation. In this embodiment, the cover plate 100 includes a front cover with integrated functional components and a rear cover for covering the toilet bowl. In this embodiment, the positioning member 500 is fitted into the positioning part 410 provided in the support member 400, and the support member 400 is clamped and fixed in conjunction with the first guide structure 310. In other embodiments, the positioning member 500 can also be a pin, clamp, etc.

[0044] In some embodiments, such as Figures 1-3As shown, the main support component 300 is provided with a second guide structure 320, and a positioning component 500 is disposed on the second guide structure 320 and can slide along the direction defined by the second guide structure 320. The sliding position of the positioning component 500 includes at least a locked position and an unlocked position. In the locked position, the position of the support component 400 is fixed by the positioning component 500. In the unlocked position, the positioning component 500 makes way for the support component 400. It can be understood that when the positioning component 500 is in the locked position, the position of the support component 400 is fixed by the positioning component 500, and at this time, the cover plate 100 will not fall under the support of the support component 400. Furthermore, when the cover plate 100 is fixedly connected to the support component 400, the cover plate 100 will not only not fall, but will also remain stationary as the support component 400 is locked. Thus, in an initial state where the cover plate 100 is not raised, the cover plate 100 can maintain a high degree of structural stability. When unlocking is required, the positioning member 500 can be moved to disengage from the locked position and move to the unlocked position, thereby releasing the restriction on the movement of the support member 400 by the positioning member 500. In this embodiment, the defining direction of the first guide structure 310 and the defining direction of the second guide structure 320 are perpendicular to each other.

[0045] In some embodiments, such as Figures 1-3 As shown, the support member 400 is provided with at least one positioning part 410 for cooperating with the positioning member 500. In the locked position, the positioning member 500 is close to the positioning part 410 and cooperates with the positioning part 410 to fix the relative position of the support member 400 and the main support member 300. In the unlocked position, the positioning member 500 is away from the positioning part 410. In this embodiment, the upper end of the support member 400 is provided with a cap 420, and the cap 420 is provided with a plurality of connecting holes for locking with the cover plate 100. In other embodiments, there can be multiple positioning parts 410 on the support member 400, and the multiple positioning parts 410 are arranged along the height direction. By cooperating with the positioning member 500 and the positioning parts 410 at different heights, the locking height of the support member 400 can be controlled, and the cover plate 100 can also be kept at a certain lifting height, which facilitates the cleaning of the toilet base 200 below the cover plate 100.

[0046] In some embodiments, such as Figures 1-3 As shown, the first guide structure 310 includes a first guide channel 311, with a support member 400 disposed within the first guide channel 311. The outer periphery of the first guide channel 311 is provided with a threaded portion 312 for locking onto the toilet base 200. It can be understood that the method of locking the main support member 300 to the toilet base 200 via the first guide channel 311 not only facilitates installation but also provides high stability. The threaded portion 312 can be screwed into a threaded hole in the toilet base 200 or passed through the toilet base 200 and locked with a nut.

[0047] In some embodiments, such as Figures 1-3As shown, a reset member 540 is provided between the positioning member 500 and the supporting main member 300. The reset member 540 is used to drive the positioning member 500 to automatically return to the locked or unlocked position. It can be understood that the reset member 540 can be a controllable active mechanism or an elastic component. In this embodiment, the reset member 540 is a spring. One end of the spring is constrained by the supporting main member 300, and the other end of the spring deforms and stores force when compressed by the positioning member 500. After the positioning member 500 is no longer subjected to external force, the spring force is released to push the positioning member 500 to reset. In this embodiment, the positioning member 500 has a positioning cavity 510, and a positioning block 330 is provided inside the positioning cavity 510. The positioning block 330 is fixed to the supporting main member 300, and the reset member 540 is located between the inner wall of the positioning cavity 510 and the positioning block 330.

[0048] In some embodiments, such as Figures 1-3 and Figure 6 As shown, the positioning component 500 is composed of a first positioning rod 520 and a second positioning rod 530 spliced ​​together. The first positioning rod 520 and the second positioning rod 530 are used to fix the positions of the two independent support components 400 respectively. It can be understood that the included angle between the first positioning rod 520 and the second positioning rod 530 can be adjusted according to the setting position of the two independent support components 400. For example, the included angle between the first positioning rod 520 and the second positioning rod 530 can be 30 degrees, 180 degrees, or others. In this embodiment, the splicing structure of the first positioning rod 520 and the second positioning rod 530 includes a fastening groove 521 provided in the first positioning rod 520 and a fastening head 531 provided in the second positioning rod 530. The fastening head 531 is fitted into the fastening groove 521 to realize the splicing of the first positioning rod 520 and the second positioning rod 530. In other embodiments, the first positioning rod 520 and the second positioning rod 530 can also be an integrally formed structure. In this embodiment, as shown... Figure 2 and Figure 4 As shown, two independent support members 400 are positioned opposite each other on both sides of the positioning member 500, and the second positioning rod 530 is provided with a hook end for hooking the positioning part 410. The first guide structure 310 includes a first guide channel 311, the support member 400 is disposed in the first guide channel 311, and the positioning member 500 passes through the through hole provided in the first guide channel 311 and cooperates with the positioning part 410. It can be understood that the number of the first guide channel 311 and the support member 400 is not limited and can be adjusted according to the actual situation. In this embodiment, the positioning part 410 is a locking groove structure. When the positioning member 500 moves to one side under the action of external force or the squeezing of the limiting member 600, the first positioning rod 520 directly passes through the through hole of a first guide channel 311 and cooperates with the corresponding positioning part 410 to lock the support member 400 on one side. The hook end of the second positioning rod 530 moves in the same direction as the first positioning rod 520 and hooks into the through hole of another first guide channel 311 and cooperates with the corresponding positioning part 410 to lock the support member 400 on the other side.

[0049] In some embodiments, such as Figures 1-3 As shown, the sliding direction of the support member 400 is perpendicular to the sliding direction of the positioning member 500. The positioning part 410 is a locking groove provided on the support member 400. When in the locked position, one end of the positioning member 500 extends into the locking groove. When in the unlocked position, the positioning member 500 exits the locking groove.

[0050] In some embodiments, such as Figures 1-5 As shown, it also includes a limiting member 600, which moves between a limiting position and a yielding position. When the limiting member 600 is in the limiting position, it presses against one end of the positioning member 500 to limit the positioning member 500 to the locked position. When the limiting member 600 is in the yielding position, it yields to the positioning member 500, allowing the positioning member 500 to move to the unlocked position. It can be understood that the limiting member 600 can be part of the supporting main member 300, such as a stop integrally formed on the supporting main member 300. Alternatively, the limiting member 600 can also be a lifting gear column separately provided from the supporting main member 300. When the positioning member 500 approaches and cooperates with the positioning part 410, the movement direction of the positioning member 500 is restricted by the second guide structure 320. At this time, the limiting member 600 presses against the positioning member 500 to fix or support the positioning member 500, so that it maintains the distance from the positioning part 410, that is, it is always in the locked position.

[0051] like Figures 1 to 7As shown, this embodiment provides a lifting mechanism, including the cover locking structure described above. The lifting mechanism includes a rising part for lifting the cover 100, and a limiting member 600 is disposed on or integrally formed with the rising part. It can be understood that by raising or lowering the rising part, the limiting member 600 is moved, moving from its original position of pressing and limiting the positioning member 500 to a position where it is partially or completely disengaged from the positioning member 500. Under the action of the reset member 540, the positioning member 500 switches from the locked position to the unlocked position. Conversely, the positioning member 500 is controlled to switch from the unlocked position to the locked position. By providing the limiting member 600, which restricts the locking position of the positioning member 500, on the rising part of the lifting mechanism, the unlocking during lifting and the locking after lowering of the cover 100 are achieved, preventing the cover 100 from being easily lifted by the user during normal use. Specifically, this mechanism allows the cover plate 100 to be fixed by the support member 400 locked by the positioning member 500 in its normal state, i.e., when it is not raised or lowered, thereby improving the structural stability of the cover plate 100 under normal use. In this embodiment, the limiting member 600 is positioned near the center of gravity of the cover plate 100. In this embodiment, the lifting mechanism is a motor 720 gear lifting mechanism, and the limiting member 600 is a gear. The gear is located on the main support member 300 and can slide vertically. The gear meshes with the drive gear 730 of the output shaft of the motor 720 on the main support member 300. By controlling the running direction of the motor 720, the lifting of the limiting member 600 is achieved. The main support member 300 is provided with a limiting pin 340, and the gear is provided with a long limiting groove 620. The limiting pin 340 fits into the long limiting groove 620 to form a gear stroke limiting structure. In other embodiments, the lifting mechanism can be a pressure cylinder lifting mechanism, an electric cylinder lifting mechanism, etc.

[0052] In some embodiments, such as Figure 1 As shown, a free travel 710 is provided between the limiting member 600 and the cover plate 100. When the limiting member 600 is in the clearance position, it enters the free travel 710 area. The limiting member 600 is provided with a clearance part 610 for unlocking the positioning member 500 so that it can move to the unlock position. It can be understood that the free travel 710 can be a gap left between the limiting member 600 and the cover plate 100. The function of the free travel 710 is to allow the limiting member 600 to unlock the positioning member 500 and the support member 400 that is limited by it when it rises. After unlocking, the cover plate 100 is then lifted, avoiding the support member 400 from getting stuck and unable to be lifted when it is locked. Specifically, when the limiting member 600, i.e. the toothed column, rises, the positioning member 500, with one end abutting against the limiting member 600, enters the clearance part 610 under the action of the reset member 540. At this time, the positioning member 500 switches from the locked position to the unlocked position, and the receiving member 400 is no longer restricted by the positioning member 500 and can slide freely along the direction defined by the first guide structure 310. At this time, the limiting member 600 can lift the cover plate 100.

[0053] In this embodiment, the main support component 300 equipped with the lifting mechanism is disposed on the ceramic part of the toilet base 200, and two independent support components 400 are installed on the main support component 300. The lid 100 can perform vertical reciprocating motion under the push of the lifting mechanism. For example:

[0054] 1. Initial state: The toothed column is in a low position. At this time, the first positioning rod 520 is pushed to the left by the inclined surface 630 on the toothed column, and the distal end of the first positioning rod 520 is inserted into the positioning part 410 of the support member 400, i.e., a locking groove. Since the second positioning rod 530 is fixedly installed with the first positioning rod 520, the second positioning rod 530 also slides to the left and is inserted into the locking groove of the other support member 400. This limits the lifting of the cover plate 100, and the cover plate 100 is in a locked state at this time.

[0055] 2. Unlocking: A free travel 710 is provided between the toothed column and the main bearing component 300. Within the free travel 710, the toothed column moves upward and releases the limit on the first positioning rod 520. Under the action of the reset component 540, the first positioning rod 520 exits the locking groove of the bearing component 400, and at the same time drives the second positioning rod 530 to exit the locking groove of the other bearing component 400. At this time, the cover plate 100 is unlocked. The toothed column continues to move upward and then lifts the cover plate 100.

[0056] 3. Locking: The drive gear 730 of the motor 720 reverses and drives the toothed column downward. When the cover plate 100 has fallen back to the mounting surface of the toilet base 200, due to the idle stroke 710 of the toothed column, it continues to descend. The inclined surface 630 set on the toothed column drives the first positioning rod 520 to insert into the locking groove of the support member 400. At the same time, it drives the first positioning rod 520 to insert into the locking groove of another support member 400. At this time, the cover plate 100 is locked and cannot be lifted.
