Description

Technical Field

[0001] The invention relates to the technical field of electrical appliance accessories, and in particular to a fan-shaped supporting platform. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the existing side-opening drum washing machine, clothes are easily dropped when being taken out, and there is no temporary storage place for small pieces of clothes in particular. Therefore, a supporting platform that can be opened and closed synchronously with the washing machine door is needed to temporarily support some clothes.

[0004] After searching, a Chinese invention patent with patent application number CN202211478932.8 was found, which discloses a clothing processing device, in which a clothing anti-falling device is composed of multiple meshes, and the multiple meshes are connected by a connecting member composed of a first rod and a second rod hinged together, so that the clothing anti-falling device can be smoothly switched between an unfolded state and a folded state.

[0005] However, the provision of the connector increases the assembly cost of the clothing anti-falling device and there are too many parts. Therefore, the present application proposes a fan-shaped supporting platform with fewer parts and lower assembly cost. Summary of the invention

[0006] The main purpose of the present invention is to provide a fan-shaped supporting platform with fewer parts and lower assembly cost.

[0007] To achieve the above object, the technical solution of the present invention is implemented as follows: a fan-shaped supporting platform includes a supporting portion, wherein the supporting portion includes a plurality of stacked supporting sheets, one end of each supporting sheet is rotatably connected together, and among two adjacent supporting sheets, a first limiting member is provided on the lower supporting sheet, and a second limiting member is provided on the upper supporting sheet;

[0008] In the unfolded state, of the two adjacent supporting pieces, the upper supporting piece rotates to one side to a predetermined angle, driving the second limiting member to contact the first limiting member, so that the lower supporting piece rotates to the same side;

[0009] It also includes a first mounting seat and a second mounting seat, which are respectively connected to the supporting plates on the upper and lower sides of the supporting part, and are respectively installed on the body of the object to be installed and the opening and closing door of the object to be installed, so as to synchronously unfold the supporting part when the opening and closing door of the object to be installed is opened.

[0010] Furthermore, the first limiting member and the second limiting member are respectively one of the first protrusion and the first limiting groove. In two adjacent supporting plates, one end of the first protrusion extends into the first limiting groove. After the two adjacent supporting plates are rotated to a predetermined angle, the first protrusion contacts one of the groove walls of the first limiting groove, so that the two adjacent supporting plates are unfolded together.

[0011] Furthermore, two ribs extend from a side of the supporting sheet opposite to the first protrusion, and the two ribs are arranged along the length direction of the supporting sheet.

[0012] Furthermore, the two ribs also serve as groove walls of the first limiting groove.

[0013] Furthermore, a second protrusion and a second limiting groove are respectively provided on two adjacent supporting plates, and one end of the second protrusion extends into the second limiting groove. After the two adjacent supporting plates are aligned, the second protrusion contacts the groove wall of the second limiting groove, so that the two adjacent supporting plates are reset together.

[0014] Furthermore, the first limiting groove and the second limiting groove are the same groove body.

[0015] Furthermore, the first limiting member and the second limiting member are respectively a first elastic sheet and a second elastic sheet with elasticity, and the supporting sheet is provided with a receiving groove at the position corresponding to the first elastic sheet and the second elastic sheet, and one end of the first elastic sheet and the second elastic sheet is connected to the groove wall of the receiving groove, and the other end extends out of the receiving groove;

[0016] In the unfolded state, of the two adjacent supporting pieces, the upper supporting piece rotates to one side to a predetermined angle, driving the second elastic piece to hook the first elastic piece of the lower supporting piece, so that the lower supporting piece rotates together;

[0017] In the retracted state, the first spring sheet and the second spring sheet are unhooked, and the upper and lower supporting sheets squeeze the first spring sheet and the second spring sheet to move the first spring sheet and the second spring sheet into the receiving groove.

[0018] Furthermore, a third spring sheet and a fourth spring sheet are respectively provided on two adjacent supporting sheets, and a receiving groove is also provided at the position of the supporting sheet corresponding to each of the third spring sheet and the fourth spring sheet, and one end of the third spring sheet and the fourth spring sheet is connected to the groove wall of the corresponding receiving groove, and the other end extends out of the receiving groove;

[0019] In the unfolded state, the third spring sheet and the fourth spring sheet are separated from each other. In the folded state, after two adjacent supporting sheets are aligned, the third spring sheet and the fourth spring sheet are hooked together, so that the two adjacent supporting sheets move together and reset.

[0020] Furthermore, the middle portion of the supporting sheet is arched along its length direction.

[0021] Furthermore, one end of the supporting piece away from the rotation center is tilted upward.

[0022] Furthermore, the supporting plate is made of metal, and the first limiting member and the second limiting member are formed by stamping.

[0023] Furthermore, the supporting sheet is made of metal, and the ribs are formed by stamping or by bending two sides of the supporting sheet in the same direction.

[0024] The beneficial effects of the present invention are embodied in:

[0025] The present invention directly arranges the first limiting member and the second limiting member on the corresponding supporting sheet, and utilizes the cooperation of the first limiting member and the second limiting member to automatically drive the lower supporting sheet to rotate when the upper supporting sheet rotates, without the need to arrange additional parts, and the assembly cost is greatly reduced.

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the invention.

[0038] Embodiment 1:

[0039] like Figures 1 to 4 shown.

[0040] The present invention discloses a fan-shaped supporting platform, comprising a supporting portion 1, wherein the supporting portion 1 comprises a plurality of supporting sheets 11 stacked together in an up-and-down direction, one end of each supporting sheet 11 being rotatably connected via a connecting shaft; of two adjacent supporting sheets 11, a first limiting member is disposed on the lower supporting sheet 11, and a second limiting member is disposed on the upper supporting sheet 11;

[0041] In the unfolded state, of the two adjacent supporting pieces 11, the upper supporting piece 11 rotates to one side to a predetermined angle, driving the second limiting member to contact the first limiting member, so that the lower supporting piece 11 rotates to the same side;

[0042] It also includes a first mounting seat 2 and a second mounting seat 3, which are respectively connected to the bottom and top supporting plates 11 of the supporting part 1, and the first mounting seat 2 and the second mounting seat 3 are respectively installed on the body of the object to be installed and the opening and closing door of the object to be installed, so as to synchronously unfold the supporting part 1 when the opening and closing door of the object to be installed is opened.

[0043] In a specific implementation, the bottom support sheet 11 of the support part 1 is fixed to the drum washing machine body through the first mounting seat 2, and the top support sheet 11 of the support part 1 is mounted on the side door of the drum washing machine through the second mounting seat 3. When the side door of the drum washing machine is opened, the support part 1 can be automatically unfolded. Among them, only the first limiter can be provided on the bottom support sheet 11 of the support part 1, and only the second limiter can be provided on the top support sheet 11 of the support part 1. In addition, the other support sheets 11 are provided with both the first limiter and the second limiter.

[0044] In addition, since the supporting platform of the present application is installed between the side door of the drum washing machine and the drum washing machine body, when the side door of the drum washing machine is closed, the side door of the drum washing machine can be used to push each supporting plate 11 to rotate and reset; of course, the second limiting component on it can also be used to drive the first limiting component to move, thereby pushing each supporting plate 11 to rotate and reset.

[0045] The present invention, by directly arranging the first limiting member and the second limiting member on the corresponding supporting sheet 11, utilizes the cooperation of the first limiting member and the second limiting member so that when the upper supporting sheet 11 rotates, the lower supporting sheet 11 is automatically driven to rotate, without arranging additional parts, and the assembly cost is greatly reduced.

[0046] Of course, the first limiting member and the second limiting member can be two protrusions directly. After the upper supporting sheet 11 rotates to a predetermined angle, the two protrusions contact each other and drive the lower supporting sheet 11 to rotate synchronously through the abutment between the two protrusions.

[0047] Preferably, the supporting sheet 11 can be made of materials such as metal sheets, hard plastic sheets, etc., and mesh holes can be opened on the supporting sheet 11 to reduce weight and material.

[0048] Preferably, the first mounting base 2 and the second mounting base 3 can be fixed on the object to be mounted by means of adhesion and / or magnetic attraction.

[0049] Preferably, the first mounting seat 2 and the second mounting seat 3 are L-shaped, and the two sides of the L-shape are respectively connected to the corresponding supporting sheet 11 and the corresponding object to be mounted. Of course, the first mounting seat 2 and the second mounting seat 3 can also be a half shell shape, and the first mounting seat 2 and the second mounting seat 3 are buckled together to cover the internal supporting sheet 11.

[0050] In one embodiment, the first limiting member and the second limiting member are respectively one of the first protrusion 12 and the first limiting groove 13. In two adjacent supporting plates 11, one end of the first protrusion 12 extends into the first limiting groove 13. The first limiting groove 13 is larger than the first protrusion 12. After the two adjacent supporting plates 11 are rotated to a predetermined angle, the first protrusion 12 contacts one of the groove walls of the first limiting groove 13, so that the two adjacent supporting plates 11 move together.

[0051] In a specific implementation, the "predetermined angle" refers to the angle between two adjacent supporting pieces 11 when the supporting portion 1 is opened. When the upper supporting piece 11 is rotated to a predetermined angle relative to the lower supporting piece 11, the first protrusion 12 moves to one side of the first limiting groove 13 and contacts the side wall of the first limiting groove 13, and then the upper supporting piece 11 continues to rotate, and through the cooperation between the first limiting groove 13 and the first protrusion 12, the lower supporting piece 11 is driven to rotate synchronously.

[0052] Such a design can shorten the gap between the upper and lower supporting sheets 11, so that the upper and lower supporting sheets 11 can be in direct contact with each other, thereby ensuring the supporting strength.

[0053] In one embodiment, two ribs 14 extend upward or downward from one side of the supporting sheet 11, and the two ribs 14 are arranged along the length direction of the supporting sheet 11. Of course, other ribs 14 may extend from the bottom of the supporting sheet 11, and the directions of the other ribs 14 are not limited.

[0054] In one embodiment, the two ribs 14 also serve as the groove walls of the first limiting groove 13 .

[0055] In a specific implementation, the ribs 14 can enhance the bearing capacity of the supporting sheet 11 on the one hand, and can also serve as the groove wall of the first limiting groove 13 on the other hand, so that there is no need to make additional grooves on the supporting sheet 11, saving processing costs.

[0056] In one embodiment, two adjacent supporting sheets 11 are further provided with a second protrusion 15 and a second limiting groove, one end of the second protrusion 15 extends into the second limiting groove, the second limiting groove is larger than the second protrusion 15, and after the two adjacent supporting sheets 11 are aligned, the second protrusion 15 contacts the groove wall of the second limiting groove, so that the two adjacent supporting sheets 11 move together and reset. When the supporting sheet 11 is made of metal, the second protrusion 15 can be formed by stamping.

[0057] In a specific implementation, when the side door of the drum washing machine is closed, the upper supporting piece 11 moves toward the main body of the drum washing machine, so that the upper supporting piece 11 is aligned with the supporting piece 11 below it, and the corresponding second protrusion 15 contacts the groove wall of the second limiting groove, and then the upper supporting piece 11 continues to move toward the main body of the drum washing machine and drives the supporting piece 11 below it to move together, and each supporting piece 11 is like this, and is folded in sequence from top to bottom.

[0058] In one embodiment, the first limiting groove 13 and the second limiting groove are the same groove body. This design has lower cost and more reasonable structure.

[0059] In one embodiment, one end of the supporting sheet 11 away from the rotation center is tilted upward.

[0060] Specifically, the supporting piece 11 can be tilted upward in an arc shape, or tilted upward in a straight line. During production, the supporting piece 11 can be made into a corresponding shape and then assembled. After the assembly, the end of the supporting part 1 corresponding to the material will be tilted (it does not need to be tilted too much, and the tilted structure is mainly used to adjust the force so that the middle part of the supporting part 1 is not easy to collapse). By making one end of the supporting part 1 tilt upward, not only the bearing capacity of the supporting part 1 is further improved, but also the clothes are not easy to slide off the supporting part 1, and the structure is relatively simple.

[0061] In one embodiment, both sides of the supporting piece 11 in the length direction are bent upward or downward, so that the middle part of the supporting piece 11 is arched along the length direction. This design can further improve the bearing capacity of the supporting part 1.

[0062] In one embodiment, the supporting sheet 11 is made of metal, and the first protrusion 12 and the first limiting groove 13 are formed by stamping. This design is simple and convenient to produce. Meanwhile, if the supporting sheet 11 is a hard plastic sheet, the first protrusion 12 and the first limiting groove 13 can be directly formed by injection molding / extrusion molding.

[0063] In one embodiment, the support sheet 11 is made of metal, and the ribs 14 are formed by stamping or bending two sides of the support sheet 11 in the same direction. Meanwhile, if the support sheet 11 is a hard plastic sheet, the ribs 14 can be directly formed by injection molding / extrusion molding with the support sheet 11.

[0064] Embodiment 2:

[0065] like Figures 5 to 8 shown.

[0066] The difference between this embodiment and the first embodiment is that the structures of the first limiting member and the second limiting member are different, specifically:

[0067] The first limiting member and the second limiting member are respectively a first elastic sheet 16 and a second elastic sheet 17 with elasticity, and the supporting plate 11 is provided with a receiving groove 18 at the position corresponding to the first elastic sheet 16 and the second elastic sheet 17, and one end of the first elastic sheet 16 and the second elastic sheet 17 is connected to the groove wall of the receiving groove 18, and the other end extends out of the receiving groove 18;

[0068] In the unfolded state, after the two adjacent supporting pieces 11 rotate to a predetermined angle, the second elastic piece 17 in the upper supporting piece 11 hooks the first elastic piece 16 in the lower supporting piece 11, driving the lower supporting piece 11 to move together;

[0069] In the folded state, when the upper supporting piece 11 of the two adjacent supporting pieces 11 is folded and rotated, the first elastic piece 16 and the second elastic piece 17 are unhooked, and the upper supporting piece 11 squeezes the first elastic piece 16 on the lower supporting piece 11, and the lower supporting piece 11 squeezes the second elastic piece 17 on the upper supporting piece 11, so that the first elastic piece 16 and the second elastic piece 17 are squeezed and moved into the receiving groove 18. This design can ensure that the overall thickness of the supporting part 1 will not change too much, and prevent the supporting part 1 from exceeding the distance between the bottom of the side door of the drum washing machine and the bottom of the opening of the drum washing machine.

[0070] Preferably, two adjacent supporting plates 11 are further provided with a third elastic piece 111 and a fourth elastic piece 112, respectively. The supporting plate 11 is also provided with a receiving groove 18 at the position corresponding to each of the third elastic piece 111 and the fourth elastic piece 112. One end of the third elastic piece 111 and the fourth elastic piece 112 is connected to the groove wall of the corresponding receiving groove 18, and the other end extends out of the receiving groove 18.

[0071] In the unfolded state, the third spring piece 111 and the fourth spring piece 112 are separated from each other. In the folded state, after the two adjacent supporting pieces 11 are aligned, the third spring piece 111 and the fourth spring piece 112 are hooked together, so that the two adjacent supporting pieces 11 move together and reset. In a specific implementation, when the side door of the drum washing machine is closed, the upper supporting piece 11 moves toward the main body of the drum washing machine, so that the upper supporting piece 11 is aligned with the supporting piece 11 below it, and the corresponding third spring piece 111 and the fourth spring piece 112 are hooked together, and then the upper supporting piece 11 continues to move toward the main body of the drum washing machine and drives the supporting piece 11 below it to move together, and each supporting piece 11 is the same, and is folded in sequence from top to bottom.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0073] It should be noted that if the embodiments of the invention involve directional indications (such as up and down), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0074] In addition, the meaning of "and / or" appearing in the full text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the invention.
