Description

Technical Field

[0001] The utility model relates to a flip obstacle-avoiding hinge for an intelligent toilet upper cover. Background Art

[0002] Multi-link hinges are widely used in various technical fields. Some hinges can be used to solve the problem of insufficient rotational actuation space of pivotal connecting parts. For example, the toilet cover assembly disclosed in the Chinese utility model patent (CN203226762U) has a first support 1 fixed on the cover 20 and a third support 7 fixed on the toilet 40. The first link 2 and the second link 9 are connected to the first support 1 and the third support 7 through four pins, namely the first pin 3, the first pin 4, the first pin 5, and the first pin 6, so that when the cover 20 is flipped up, the four pins are rotating, and the first support 1 is displaced and flipped. During the opening process of the cover 20, the gap between the rear end of the cover 20 and the docking part of the ceramic toilet 40 can be 2 mm, which greatly improves the utilization of space. However, this hinge is used to lift the rear end of the cover plate 20 across the docking position of the ceramic toilet 40, rather than rotating the rear end of the cover plate 20 before the docking position facade of the ceramic toilet 40. It is not applicable to the toilet cover with a full seat ring.

[0003] Another example is the door hinge: the multi-link hinge disclosed in Korean Invention Patent (Application No. KR1020170009725) uses links 30, 50, and 60 to displace the door D relative to the box body B when it is opened or closed, thereby reducing the rotational space of the door D relative to the box body B. For another example, to prevent the rear edge of the hood from hitting the outside of the car's engine compartment when flipping, the automobile engine hood hinge disclosed in Korean Invention Patent (Application No. KR1020150037169) also uses a double rocker hinge structure to prevent the hood from hitting the edge of the car's engine compartment during flipping.

[0004] The above-mentioned toilet cover hinges, car doors or multi-link hinges for engine compartment lids are designed to have structures and functions in which the corresponding hinges are actuated by manual flipping of the toilet cover, car door or engine compartment lid. Therefore, they cannot be applied to smart toilets and actuated by a motor shaft, that is, the above-mentioned hinges cannot be used on smart toilets with automatic flip-up. Utility Model Content

The end face of the positioning shaft is provided with a rotating shaft that is screwed into the second sleeve, and the rotating shaft extends into the annular groove at the end part on the inner side of the second sleeve and is buckled with a retaining spring that limits the axial displacement of the rotating shaft relative to the second sleeve.

[0012] As a further improvement, a diameter-reducing platform is axially extended on the wall of the pivot hole, and an adapting surface is provided on the positioning shaft for the diameter-reducing platform to be adapted and inserted to limit the rotation of the positioning shaft relative to the pivot hole.

[0013] As a further improvement, the two first shaft sleeves spaced apart on the left and right sides at the front end of the fixing seat and the two second shaft sleeves spaced apart on the left and right sides at the rear end are integrally formed with the fixing seat in an I-shape.

[0014] As a further improvement, the fixing seat is a left and right half structure arranged at intervals, the interval between the two is L length, and the middle part of the supporting platform is extended to the left and right directions by L length.

[0042] The structures of the various components of the present invention are described below.

[0043] like Figure 1 and Figure 2 As shown, the two first hinges 30 are arranged in mirror symmetry on the left and right sides in front between the fixed seat 10 and the supporting platform 20. The front end of the fixed seat 10 is provided with two first shaft sleeves 11 whose axial holes are coaxially pivoted with the first hinge axis position A, and the rear end is provided with two second shaft sleeves 12 whose axial holes are coaxially pivoted with the second hinge axis position B; the front end of the supporting platform 20 is provided with two third shaft sleeves 21 whose axial holes are coaxially pivoted with the third hinge axis position C, and the rear end is provided with two fourth shaft sleeves 22 whose axial holes are coaxially pivoted with the fourth hinge axis position D; the inner side of the bottom end of the first shaft sleeve 11 is provided with a rotating shaft R that is screwed in and fits in the first shaft sleeve 11, and the inner side of the top end is provided with a rotating shaft R that is screwed in and fits in the third shaft sleeve 21; the inner side of the top end of the second hinge rod 40 is provided with a rotating shaft R that is screwed in and fits in the fourth shaft sleeve 22, and the ends of the rotating shaft R extending into the inner side of the shaft sleeve are provided with an annular groove G, and the insert buckle in the annular groove G is fitted with a retaining spring 70 for limiting the axial displacement of the rotating shaft R relative to the shaft sleeve.

[0044] like Figure 1 and Figure 2As shown, a pivot hole 41 is provided on the rotating end at the bottom end of the second hinge rod 40 provided with a torsion spring 60, and a positioning shaft 50 is inserted and fitted in the pivot hole 41 to prevent rotation with the rotating end of the fixed seat 10, and the end face of the positioning shaft 50 is provided with a rotating shaft R that is screwed and fitted in the second sleeve 12, and the rotating shaft R extends into the annular groove G at the end portion on the inner side of the second sleeve 12 and is buckled into a retaining spring 70 that limits the axial displacement of the rotating shaft R relative to the second sleeve 12; a reducing platform 411 extends axially on the wall of the pivot hole 41, and an adapting surface 501 is provided on the positioning shaft 50 for the adapting and inserting of the reducing platform 411 to limit the rotation of the positioning shaft 50 relative to the pivot hole 41; the torsion spring 60 is sleeved on the circumferential side of the rotating shaft R of the positioning shaft 50, and one force-bearing end of the torsion spring 60 is connected to the positioning shaft 50, and the other force-bearing end is connected to the second sleeve 12.

[0045] The following combination Figures 1 to 5 The utility model is described in detail, and the steps and principles of the support platform 20 of the obstacle avoidance hinge rotating relative to the fixed base 10 are as follows:

[0046] like Figure 2 As shown, when the hinge is in the initial state, the fixing seat 10 and the bearing platform 20 are parallel, the first hinge axis position A and the second hinge axis position B are in the same straight line position, and the height position of the fourth hinge position D is lower than the height position of the third hinge position C; Figure 2 and Figure 3 As shown, when the supporting platform 20 is flipped upward 30° relative to the fixing base 10 from the initial state, the motor shaft actuates the rotating end of the second hinge 40 on the right side to rotate, thereby driving the third hinge axis position C and the fourth hinge axis position D to swing upward and forward, thereby allowing the fixing base 10 to complete the upward flip 30° action.

[0047] like Figure 3 and Figure 4 As shown, during the process of the supporting platform 20 being flipped upward to 58°, the third hinge axis position C and the fourth hinge axis position D continue to swing upward and forward until the second hinge axis position B, the third hinge axis position C and the fourth hinge axis position D are on the same straight line, and the straight line, the fixing base 10 and the first hinge rod 30 form a stable triangular support structure; Figure 4 and Figure 5 As shown, as the supporting platform 20 continues to flip up until it is fully opened, the third hinge axis position C swings downward and backward, and the fourth hinge axis position D swings downward and forward; until the third hinge axis position C at the top end of the second hinge rod 40 abuts against the outer wall of the first hinge rod 30, the second hinge rod 40 stops swinging, and the supporting platform 20 is in a fully opened state.

[0048] The present application is divided into different embodiments according to the different structures of the fixing base 10 and the supporting platform 20 .

[0049] Example 1:

[0050] like Figures 1 to 5As shown, the two first shaft sleeves 11 spaced apart at the front and rear of the fixing base 10 and the two second shaft sleeves 12 spaced apart at the rear and front of the fixing base 10 are integrally formed in an I-shaped configuration. The assembly steps of the first embodiment are as follows: the support platform 20 is placed above the fixing base 10, the rotating shafts R on the first hinge 30 and the second hinge 40 are sequentially inserted into the corresponding shaft sleeves, and the retaining spring 70 is inserted into the annular groove G at the end of the rotating shaft R extending out of the sleeve to form the first hinge position A, the third hinge position C, and the fourth hinge position D; the motor shaft is inserted into the flat shaft hole 42 at the rotating end of the second hinge 40 on the right side, and the positioning shaft 50 and the torsion spring 60 are then installed in the rotating end of the rotating shaft R on the left side to form the second hinge position B.

[0051] Example 2:

[0052] like Figure 18 As shown, the fixing seat 10 is a left and right half structure arranged at an interval, and the interval between the two is L length, and the middle part of the supporting platform 20 extends to the left and right by the length L; the interval between the two halves of the fixing seat 10 can make way for the spray gun (not shown) installed on the toilet; the other component structures, assembly relationships and working principles are the same as those in Example 1, so they will not be repeated here.

[0053] like Figures 1 to 18 As shown, the smart toilet of the present invention has the above-mentioned smart toilet cover flip obstacle avoidance hinge, and also includes a toilet 100 and a movement shell base 200. The front end of the movement shell base 200 is hinged with a seat ring 201 and an upper cover 202. The rear side of the toilet 100 has a boss 101. The front profile facade 102 on the boss 101 is the same as and parallel to the rear edge facade 2021 of the upper cover 202 in the initial closed state; the fixed seat 10 of the obstacle avoidance hinge is fixedly connected to the middle rear part of the movement shell base 200 by bolts (not shown in the figure), and the supporting platform 20 is fixed to the middle part of the rear end of the upper cover 202 of the movement shell base 200 by bolt connection, and a cover plate 300 for covering and hiding the fixed seat 10 is installed at the rear end of the seat ring 201. With this design, the cover plate of the smart toilet 100 is more beautiful because the fixed seat 10 will not be exposed.

[0054] The following combination Figures 2 to 17 Detailed description of the utility model, the steps and principles of the intelligent toilet cover 202 flipping over and avoiding obstacles on the boss 101:

[0055] like Figure 2 and Figures 7 to 10As shown, when the upper cover 202 is in the initial closed state, the rear edge facade 2021 of the upper cover 202 is parallel to the front profile facade 102 on the rear side boss 101, and the motor shaft actuates the second hinge shaft 40 to flip upward to drive the supporting platform 20 to flip upward. During this process, the supporting platform 20 moves forward away from the front profile facade 102, so that the rear edge facade 2021 of the upper cover 202 can avoid the front profile facade 102 of the boss 101, avoiding the problem in the prior art that the rear edge facade 2021 of the upper cover 202 will be blocked by the boss 101 and cannot be flipped open due to the coaxial rotation of the seat ring 201 and the upper cover 202.

[0056] like Figure 3 and Figure 11 、 Figure 12 As shown, when the upper cover 202 is turned up to 30 degrees, the upper cover 202 is turned over at the same time as the supporting platform 20 is turned up, so as to avoid the rear edge elevation 2021 of the upper cover 202 from colliding with the front profile elevation 102 of the rear boss 101 of the toilet 100; Figure 4 and Figure 13 、 Figure 14 As shown, when the upper cover 202 is turned up to 58 degrees, the rear edge facade 2021 of the upper cover 202 is always in front of the front profile facade 2021 and will not collide with the front profile facade 2021; Figure 5 and Figures 15 to 17 As shown, until the upper cover 202 is fully opened, the rear edge elevation 2021 of the upper cover 202 will not collide with the front profile elevation 2021 of the rear boss 101 of the toilet 100. In other words, during the entire opening process, the rear edge elevation 2021 of the upper cover 202 is located in front of the front profile elevation 102 of the boss 101 and maintains a certain safe distance. The upper cover 202 does not cross the rear boss 101 of the toilet during the entire opening process. The principle of the upper cover 202 falling down is similar to the above-mentioned principle of the opening up, so it will not be described in detail here.

[0057] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. A person skilled in the art may make various modifications or changes without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and be defined by the claims.
