A fan-shaped support platform, comprising a support portion (1), which comprises a plurality of stacked support plates (11), the support plates being rotatably connected together at one end; among two adjacent support plates, the lower support plate is provided with a first limiting member, and the upper support plate is provided with a second limiting member; in an expanded state, when the upper support plate rotates to one side to reach a predetermined included angle, the upper support plate drives the second limiting member to come into contact with the first limiting member, causing the lower support plate to rotate to the same side. The fan-shaped support platform further comprises a first mounting base (2) and a second mounting base (3), which are respectively mounted on the body of an object to be installed on and an opening and closing door of said object, so as to synchronously expand the support portion when the opening and closing door of said object is opened. In the fan-shaped support platform, by means of the cooperation between the first limiting member and the second limiting member, the rotation of the upper support plate automatically drives the lower support plate to rotate, eliminating the need to provide an additional component, and thereby greatly reducing assembly costs.

Description

A fan-shaped support platform Technical Field

[0001] This invention relates to the field of electrical component technology, specifically to a fan-shaped support platform. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Existing side-opening drum washing machines often cause clothes to fall out when taking them out, and there is no place to temporarily store particularly small items. Therefore, there is a need for a support platform that can open and close synchronously with the washing machine door to temporarily support some clothes.

[0004] A search revealed a Chinese invention patent with patent application number CN202211478932.8, which discloses a clothing handling device. In this device, multiple mesh panels are used to form a clothing anti-fall device, and the multiple mesh panels are connected by a connector consisting of a first rod and a second rod that are hinged together, so that the clothing anti-fall device can smoothly switch between an unfolded state and a folded state.

[0005] However, the design of this connector increases the assembly cost of the clothing anti-fall device due to the large number of parts. Therefore, this application proposes a fan-shaped support platform with fewer parts and lower assembly cost. Summary of the Invention

[0006] The main objective of this invention is to provide a fan-shaped support platform with fewer parts and lower assembly costs.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: a fan-shaped support platform includes a support part, the support part includes a plurality of support pieces stacked together, one end of each support piece is rotatably connected together, and in two adjacent support pieces, a first limiting member is provided on the lower support piece and a second limiting member is provided on the upper support piece.

[0008] In the unfolded state, among two adjacent support pieces, the upper support piece rotates to one side to a predetermined angle, causing the second limiting member to contact the first limiting member, thus causing the lower support piece to rotate to the same side.

[0009] It also includes a first mounting base and a second mounting base, which are respectively connected to the support plates on the upper and lower sides of the support portion. The first mounting base and the second mounting base 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 support portion when the opening and closing door of the object to be installed is opened.

[0010] Furthermore, the first limiting member and the second limiting component are respectively one of the first protrusion and the first limiting groove. In two adjacent support pieces, one end of the first protrusion extends into the first limiting groove. After the two adjacent support pieces rotate to a predetermined included angle, the first protrusion contacts one of the groove walls of the first limiting groove, so that the two adjacent support pieces unfold together.

[0011] Furthermore, on the side of the support piece opposite to the first protrusion, two ribs extend out, and the two ribs are arranged along the length direction of the support piece.

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

[0013] Furthermore, each of the two adjacent support pieces is provided with a second protrusion and a second limiting groove. One end of the second protrusion extends into the second limiting groove. After the two adjacent support pieces are aligned, the second protrusion contacts the groove wall of the second limiting groove, so that the two adjacent support pieces 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 component are respectively elastic first springs and second springs, and the supporting piece is provided with receiving grooves at the positions of the corresponding first springs and second springs. One end of the first spring and the second spring 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, among two adjacent support pieces, the upper support piece rotates to one side to a predetermined angle, which causes the second spring piece to hook onto the first spring piece in the lower support piece, causing the lower support piece to rotate together.

[0017] In the folded state, the first and second springs are unhooked, and the upper and lower support plates press against the first and second springs, causing them to move into the receiving groove.

[0018] Furthermore, a third spring and a fourth spring are respectively provided on two adjacent support plates. A receiving groove is also provided at the corresponding position of the third spring and the fourth spring on the support plate. One end of the third spring and the fourth spring 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 and fourth springs are separated from each other. In the retracted state, after the two adjacent support pieces are aligned, the third and fourth springs hook together, so that the two adjacent support pieces move and reset together.

[0020] Furthermore, the middle portion of the support piece arches along its length.

[0021] Furthermore, the end of the support piece furthest from the center of rotation is curved upwards.

[0022] Furthermore, the support piece is made of metal, and the first and second limiting members are stamped together.

[0023] Furthermore, the support piece is made of metal, and the ribs are formed by stamping or by bending both sides of the support piece in the same direction.

[0024] The beneficial effects of this invention are reflected in:

[0025] This invention directly sets the first limiting member and the second limiting component on the corresponding support piece. By utilizing the cooperation of the first limiting member and the second limiting component, the lower support piece is automatically driven to rotate when the upper support piece rotates. No additional parts are required, and the assembly cost is greatly reduced. Attached Figure Description

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the invention, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0037] Example 1:

[0038] As shown in Figures 1 to 4.

[0039] The present invention discloses a fan-shaped support platform, including a support part 1, which includes a plurality of support pieces 11 stacked together in the vertical direction, one end of each support piece 11 being rotatably connected by a connecting shaft; in two adjacent support pieces 11, a first limiting member is provided on the lower support piece 11 and a second limiting member is provided on the upper support piece 11.

[0040] In the unfolded state, among two adjacent support pieces 11, the upper support piece 11 rotates to one side to a predetermined angle, causing the second limiting member to contact the first limiting member, so that the lower support piece 11 rotates to the same side.

[0041] It also includes a first mounting base 2 and a second mounting base 3, which are respectively connected to the lowermost and uppermost support pieces 11 of the support part 1. The first mounting base 2 and the second mounting base 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 simultaneously unfold the support part 1 when the opening and closing door of the object to be installed is opened.

[0042] In specific implementation, the lowermost support piece 11 of the support part 1 is fixed to the drum washing machine body via the first mounting base 2, and the uppermost support piece 11 of the support part 1 is mounted on the side door of the drum washing machine via the second mounting base 3. When the side door of the drum washing machine is opened, the support part 1 will automatically unfold. The lowermost support piece 11 of the support part 1 may only have a first limiting member, and the uppermost support piece 11 may only have a second limiting member. Other support pieces 11 may have both a first limiting member and a second limiting member.

[0043] Furthermore, since the support platform of this 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 support piece 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 and push each support piece 11 to rotate and reset.

[0044] This invention directly sets the first limiting member and the second limiting component on the corresponding support piece 11. When the upper support piece 11 rotates, the lower support piece 11 is automatically driven to rotate by the cooperation of the first limiting member and the second limiting component. No additional parts are required, and the assembly cost is greatly reduced.

[0045] Of course, the first limiting member and the second limiting member can be two protrusions. After the upper support piece 11 rotates to a predetermined angle, the two protrusions come into contact, and through the contact of the two protrusions, the lower support piece 11 rotates synchronously.

[0046] Preferably, the support plate 11 can be made of materials such as metal sheet or rigid plastic sheet, and the support plate 11 can be made of mesh to reduce weight and material usage.

[0047] Preferably, the first mounting base 2 and the second mounting base 3 can be fixed to the object to be installed by means of adhesive and / or magnetic attraction.

[0048] Preferably, the first mounting base 2 and the second mounting base 3 are L-shaped, with the two sides of the L-shape connected to the corresponding support piece 11 and the corresponding object to be installed, respectively. Of course, the first mounting base 2 and the second mounting base 3 can also be a split shell shape, with the first mounting base 2 and the second mounting base 3 fastened together to cover the internal support piece 11.

[0049] In one embodiment, the first limiting member and the second limiting component are respectively one of the first protrusion 12 and the first limiting groove 13. In two adjacent support pieces 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 support pieces 11 rotate to a predetermined included angle, the first protrusion 12 contacts one of the groove walls of the first limiting groove 13, so that the two adjacent support pieces 11 move together.

[0050] In specific implementation, the "predetermined included angle" refers to the included angle between two adjacent support pieces 11 when the support part 1 is opened. When the upper support piece 11 rotates to the predetermined angle relative to the lower support 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. Then the upper support piece 11 continues to rotate, and through the cooperation of the first limiting groove 13 and the first protrusion 12, it drives the lower support piece 11 to rotate synchronously.

[0051] This design shortens the gap between the upper and lower support plates 11, allowing them to make direct contact and ensuring support strength.

[0052] In one embodiment, two ribs 14 extend upward or downward from the side of the support piece 11 facing upward or downward, and the two ribs 14 are arranged along the length direction of the support piece 11. Of course, other ribs 14 may also extend from the bottom of the support piece 11, and the direction of the other ribs 14 is not limited.

[0053] In one embodiment, the two ribs 14 also serve as the groove walls of the first limiting groove 13.

[0054] In practice, the rib 14 can enhance the load-bearing capacity of the support plate 11 on the one hand, and also serve as the groove wall of the first limiting groove 13 on the other hand, so that there is no need to open grooves on the support plate 11, saving processing costs.

[0055] In one embodiment, two adjacent support pieces 11 are respectively provided with a second protrusion 15 and a second limiting groove. One end of the second protrusion 15 extends into the second limiting groove, which is larger than the second protrusion 15. After the two adjacent support pieces 11 are aligned, the second protrusion 15 contacts the groove wall of the second limiting groove, causing the two adjacent support pieces 11 to move and reset together. When the support pieces 11 are made of metal, the second protrusion 15 can be stamped.

[0056] In practice, when the side door of the drum washing machine is closed, the upper support piece 11 moves toward the body of the drum washing machine, so that the upper support piece 11 is aligned with the lower support piece 11, and the corresponding second protrusion 15 contacts the groove wall of the second limiting groove. Then the upper support piece 11 continues to move toward the body of the drum washing machine and drives the lower support piece 11 to move together. All support pieces 11 are like this, and they are closed from top to bottom.

[0057] In one embodiment, the first limiting groove 13 and the second limiting groove are the same groove body. This design results in lower cost and a more reasonable structure.

[0058] In one embodiment, the end of the support piece 11 furthest from the center of rotation is tilted upwards.

[0059] Specifically, the support piece 11 can be curved upwards or angled upwards in a straight line. During production, the support piece 11 can be made into the corresponding shape and then assembled. After assembly, the end of the support part 1 that receives the material will be curved upwards (it doesn't need to be curved too much; the main purpose is to use this curved structure to adjust the stress and prevent the middle of the support part 1 from collapsing). By making one end of the support part 1 curve upwards, the load-bearing capacity of the support part 1 is further improved, and the clothing is less likely to slip off the support part 1. The structure is also relatively simple.

[0060] In one embodiment, the two sides of the support piece 11 along its length are bent upwards or downwards, causing the middle part of the support piece 11 to arch along its length. This design further improves the load-bearing capacity of the support portion 1.

[0061] In one embodiment, the support piece 11 is made of metal, and the first protrusion 12 and the first limiting groove 13 are stamped. This design makes production simple and convenient. Alternatively, if the support piece 11 is made of rigid plastic, the first protrusion 12 and the first limiting groove 13 can be directly injection molded / extruded.

[0062] In one embodiment, the support piece 11 is made of metal, and the rib 14 is formed by stamping or bending from both sides of the support piece 11 in the same direction. Alternatively, if the support piece 11 is a rigid plastic sheet, the rib 14 can be directly injection molded / extruded integrally with the support piece 11.

[0063] Example 2:

[0064] As shown in Figures 5 to 8.

[0065] The difference between this embodiment and Embodiment 1 lies in the structural form of the first limiting member and the second limiting component, specifically:

[0066] The first limiting member and the second limiting component are respectively a first elastic spring 16 and a second elastic spring 17. The supporting plate 11 is provided with a receiving groove 18 at the corresponding positions of the first elastic spring 16 and the second elastic spring 17. One end of the first elastic spring 16 and the second elastic spring 17 is connected to the groove wall of the receiving groove 18, and the other end extends out of the receiving groove 18.

[0067] In the unfolded state, after the two adjacent support plates 11 rotate to a predetermined angle, the second spring plate 17 in the upper support plate 11 hooks the first spring plate 16 in the lower support plate 11, causing the lower support plate 11 to move together.

[0068] In the folded state, when the upper support piece 11 folds and rotates, the first spring piece 16 and the second spring piece 17 disengage. The upper support piece 11 presses against the first spring piece 16 on the lower support piece 11, and the lower support piece 11 presses against the second spring piece 17 on the upper support piece 11, causing the first spring piece 16 and the second spring piece 17 to move into the receiving groove 18. This design ensures that the overall thickness of the support part 1 does not change significantly, preventing the support 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.

[0069] Preferably, a third spring 111 and a fourth spring 112 are respectively provided on two adjacent support plates 11. The support plate 11 is also provided with a receiving groove 18 at the corresponding position of the third spring 111 and the fourth spring 112. One end of the third spring 111 and the fourth spring 112 is connected to the groove wall of the corresponding receiving groove 18, and the other end extends out of the receiving groove 18.

[0070] In the unfolded state, the third spring 111 and the fourth spring 112 are separated from each other. In the retracted state, after the two adjacent support pieces 11 are aligned, the third spring 111 and the fourth spring 112 hook together, causing the two adjacent support pieces 11 to move and reset together. In specific implementation, when the side door of the drum washing machine is closed, the upper support piece 11 moves towards the body of the drum washing machine, aligning the upper support piece 11 with the support piece 11 below it, and the corresponding third spring 111 and fourth spring 112 hook together. Then, the upper support piece 11 continues to move towards the body of the drum washing machine, causing the support piece 11 below it to move together. Each support piece 11 is retracted in this manner from top to bottom.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0072] It should be noted that if the embodiments of the invention involve directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0073] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B. Additionally, if the embodiments of the invention involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the invention.
