Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, and in particular to a flexible hinge for use in compact spaces. Background Technology

[0002] In floor scrubbing equipment (such as the automatic sweeper described in Chinese Patent 202430291336.2), a cover structure is generally provided to facilitate the addition of materials or the removal of garbage. In existing designs, a hinge structure is generally used to achieve the flipping of the cover. However, in existing designs, the internal flow of the machine requires vacuuming to achieve water absorption, and the cover and the cavity need to fit tightly to form a good vacuuming effect. At the same time, the cover has a soft sealing ring.

[0003] When the machine is working and drawing a vacuum, the vacuum cover will move downwards by a predetermined stroke. Therefore, the hinge needs to have a space to float up and down to ensure a tight fit between the cover and the cavity. Ordinary hinges usually cannot float up and down, while hinges specially designed with a floating structure will occupy more space, thus affecting the sealing performance. At the same time, the rotation angle of the metal hinge will also be limited (usually 90 degrees). Therefore, a clearance position needs to be set at the connection between the cover and the cavity to expand its floating space.

[0004] Therefore, it is crucial to design a design that can ensure the flipping angle of the cover while allowing it to float flexibly up and down, and that can reduce the space occupied by the connecting end. Utility Model Content

[0005] The main objective of this invention is to propose a flexible hinge for use in compact spaces. By setting a flexible hinge between the cover and the cavity, sufficient floating space can be provided between the two, while also reducing the gap between the cover and the opening.

[0006] To achieve the above objectives, this utility model proposes a flexible hinge for use in compact spaces, comprising:

[0007] A cavity, wherein the cavity has an opening and the opening has a swing-mounted cover;

[0008] A flexible hinge, comprising a first plate, a second plate, and a flexible layer integrally covering the first plate and the second plate, wherein the flexible layer forms a swing portion between the first plate and the second plate, and the first plate and the second plate swing relative to each other with the swing portion as a fulcrum.

[0009] The first plate and the second plate are respectively installed in the cavity and the cover.

[0010] In the actual design, the first and second plates serve as the support and mounting structure for the flexible hinge, thereby ensuring the stability of the installation and reducing wear. At the same time, the first and second plates are covered by a flexible layer, forming a swing section between them, which enables the relative swing of the cover. This allows the cover to have sufficient unrestricted floating space. Furthermore, the volume and structure of the swing section are smaller than those of existing hinge structures, and the folded volume can further reduce the gap between the cover and the opening. It occupies little space, and the structure is simple, reliable, and requires no additional maintenance. Attached Figure Description

[0023] like Figures 1 to 5 As shown, a flexible hinge for use in compact spaces includes:

[0024] Cavity 1, wherein the cavity 1 is provided with an opening 10, and the opening 10 is provided with a swing-mounted cover 11;

[0025] The flexible hinge 2 includes a first plate 21, a second plate 22, and a flexible layer 20 that integrally covers the first plate 21 and the second plate 22. The flexible layer 20 forms a swing portion 23 between the first plate 21 and the second plate 22, and the first plate 21 and the second plate 22 swing relative to each other with the swing portion 23 as the fulcrum.

[0026] The first plate 21 and the second plate 22 are respectively installed in the cavity 1 and the cover 11.

[0027] In the actual design, the first plate 21 and the second plate 22 serve as the support and installation structure for the flexible hinge 2, thereby ensuring the stability of the installation and reducing wear. At the same time, the first plate 21 and the second plate 22 are covered by the flexible layer 20, thereby forming the swing part 23 between them, which realizes the relative swing of the cover 11, so that the cover 11 has sufficient unrestricted floating space. Meanwhile, the volume and structure of the swing part 23 are smaller than those of the existing hinge structure, and the folded volume can further reduce the gap between the cover 11 and the opening 10. It occupies little space, and the structure is simple and reliable, requiring no additional maintenance.

[0028] Specifically, the first plate 21 and the second plate 22 are integrally injection molded through the flexible layer 20. In the actual design, the first plate 21 and the second plate 22 are placed on the fixture, and then the flexible layer 20 is injected into the cavity, thereby covering the first plate 21 and the second plate 22 while forming the swing part 23.

[0029] In this embodiment of the present invention, the flexible layer 20 is provided with a metal sheet, such as a titanium alloy, at the position of the swing part 23, which can provide a damping effect and also improve the service life of the swing part 23.

[0030] Specifically, the flexible layer 20 is made of woven tape and / or rubber tape. Flexible materials such as woven tape have a flexible range of motion during operation, while ensuring a tight fit between the cover and the cavity, and improving the stability and wear resistance of the material.

[0031] In this embodiment of the utility model, the first plate 21 is disposed on the inner side wall of the cavity 1, and the second plate 22 is disposed on the rear end wall of the cover 11.

[0032] Specifically, when the cover 11 blocks the opening, the first plate 21 and the second plate 22 are attached to each other or set opposite to each other, so that the cover 11 can be inserted into the opening 10 as a whole. This achieves the goal of making the upper wall of the cover 11 flush with the upper wall of the opening 10 in a relatively limited space. At the same time, the swing part 23 has a degree of deformation, so the cover 11 can swing at a large angle (it can swing 180 degrees, but is not limited to 180 degrees), which facilitates the placement / removal of materials or garbage.

[0033] In this embodiment of the utility model, the swing part 23 has a predetermined width, and the swing part 23 can be deformed under the action of force, specifically, the horizontal plane can be deformed into a curved surface, so that the first plate 21 and the second plate 22 can fit together.

[0034] Specifically, when the swing part 23 changes from a horizontal plane to a curved surface, the first plate 21 and the second plate 22 are in contact.

[0035] In this embodiment of the present invention, the upper end of the rear wall of the cover 11 is provided with a first arc-shaped surface 31, and the upper end of the opening 10 of the cavity 1 is provided with a second arc-shaped surface 32. The arrangement of the first arc-shaped surface and the second arc-shaped surface can improve the cover 11 to have sufficient floating space, while reducing the wear on the swing part 23 and improving its service life.

[0036] Specifically, the lower wall of the cover 11 on the side away from the flexible hinge 2 is provided with an elastic hook 3. When the cover 11 is actually locked, the main body is provided with a locking groove (not shown). When the elastic hook 3 cooperates with the locking groove, it can apply pressure to the cover 11 to move in the direction of the flexible hinge 2, thereby making the first plate 21 and the second plate 22 fit together.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
