Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a hinge mechanism and an embedded electrical device. Background Technology

[0002] In modern home furnishing products, in order to integrate electrical appliances with home decoration and achieve a beautiful and neat layout, a recessed groove that matches the length, width and height of the electrical appliance is usually prefabricated. After the electrical appliance is embedded in the recessed groove, the door panel is flush with the end of the recessed groove.

[0003] In these types of appliances, whether refrigerators or wine cabinets, the door panels need to open at an angle slightly greater than a right angle relative to the cabinet body to facilitate user access to items. However, because the gap between the door panel and the inner wall of the recessed storage compartment is extremely small, the front edge of the door panel can easily interfere with the inner wall of the recessed storage compartment before the door is opened to the preset angle, resulting in an insufficient opening angle. Increasing the gap between the door panel and the inner wall of the recessed storage compartment, however, would result in unsightly appearance and poor space utilization. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide a hinge mechanism that ensures the door panel reaches a preset opening angle without interference, provided that the size of the embedded electrical device matches the recessed groove; the second objective is to provide an embedded electrical device using the above-mentioned hinge mechanism.

[0005] A hinge mechanism according to a first aspect of the present invention includes: a cabinet having a cavity opening forward; a door panel rotatably disposed on the cabinet for opening or closing the cavity; and two door hinge assemblies respectively disposed at the upper and lower ends of the left side or the upper and lower ends of the right side of the cabinet, the two door hinge assemblies being respectively connected to the upper and lower ends of the corresponding side of the door panel; wherein the door hinge assembly includes a cantilever member fixed to the front end face of the cabinet and extending forward, and a transition member fixed to the door panel and rotatably connected to the extended end of the cantilever member.

[0006] The hinge mechanism according to the embodiments of the present utility model has at least the following beneficial effects: The hinge mechanism described above uses a cantilever to shift the axis of rotation between the door panel and the cabinet forward. The door panel is rotatably connected to the cantilever via a connector on the door panel to open and close. Assuming the dimensions of the embedded electrical equipment match the recessed slot, the forward shift of the axis of rotation between the door panel and the cabinet prevents the door panel from easily touching the inner wall of the recessed slot when the opening angle is large, thus avoiding interference.

[0007] In some embodiments of this utility model, one of the extended end of the cantilever member and the adapter member is provided with a pivot, and the other is provided with a shaft hole that mates with the pivot. The projection of the outline edge of the door panel in the front-rear direction is located within the outline edge of the cabinet. The distance between the axis of the pivot and the front end face of the cabinet is A, the distance between the axis of the pivot and the front end face of the door panel is B, and the distance between the axis of the pivot and the adjacent side surface of the cabinet is C, satisfying: 38 mm ≤ A ≤ 42 mm, 11 mm ≤ B ≤ 15 mm; 15 mm ≤ C ≤ 17 mm.

[0008] In some embodiments of this utility model, the overhanging member is an L-shaped sheet metal part, which includes a vertical section fixedly attached to the front end face of the opening edge of the cavity and a horizontal section connected to the upper end of the vertical section. Neither the horizontal section nor the vertical section protrudes from the upper surface of the cabinet or the adjacent side surface.

[0009] In some embodiments of this utility model, the adapter is a flat plate fixed to the top wall of the door panel, the flat plate abutting against the lower surface of the horizontal section, and an angle limiting mechanism is provided between the flat plate and the horizontal section.

[0010] In some embodiments of this utility model, the angle limiting mechanism includes a blocking part bent upward in the flat plate and a limiting groove recessed in the side edge of the horizontal section. The blocking part rotates with the flat plate to abut against the bottom of the limiting groove to limit the opening angle of the door panel.

[0011] In some embodiments of this utility model, the L-shaped sheet metal part is made of stainless steel, the thickness of the L-shaped sheet metal part is between 2.5mm and 3mm, the horizontal section is a rectangular plate, the maximum width of the rectangular plate is D, and the distance between the bottom of the limiting groove and one side edge of the rectangular plate is E, satisfying: E≥0.45D.

[0012] In some embodiments of this utility model, the door panel includes an inner layer panel and an outer layer panel abutting the front surface of the inner layer panel. The inner layer panel is used to open and close the opening of the cavity. The flat plate is installed on the upper surface of the inner layer panel. The projection of the outline edge of the outer layer panel and the outline edge of the cabinet body in the front-rear direction coincides. The outline edge of the outer layer panel is located on the outer periphery of the outline edge of the inner layer panel to cover the flat plate and the L-shaped sheet metal part.

[0013] In some embodiments of this utility model, the inner layer plate has a light-transmitting plate in the middle, and the outer layer plate is a decorative frame plate in the shape of a square surrounding the outer periphery of the light-transmitting plate. The four corners of the decorative frame plate are respectively installed to the outer periphery of the inner layer plate by bolt assemblies.

[0014] In some embodiments of this utility model, the end of the flat plate extends toward the outer layer plate, the outer layer plate is provided with a relief groove corresponding to the extended portion of the flat plate, the end of the flat plate is provided with a shaft hole, the end of the horizontal section is provided with a pivot passing through the shaft hole, and a rubber gasket is sleeved on the outside of the pivot and sandwiched between the horizontal section and the flat plate.

[0015] An embedded electrical device according to a second aspect of this utility model includes a hinge mechanism of any of the above-described technical solutions. Provided that the dimensions of the embedded electrical device match the recessed groove, because the axis of rotation of the door panel relative to the cabinet is offset forward, the door panel is less likely to touch the inner wall of the recessed groove even when the opening angle is large, thus avoiding interference problems.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] See Figures 1 to 4This utility model discloses a hinge mechanism, comprising: a cabinet 100, wherein the cabinet 100 has a forward-opening cavity 110; a door panel 200, rotatably disposed on the cabinet 100, for opening or closing the opening of the cavity 110; and two door hinge assemblies 300, respectively disposed at the upper and lower ends of the left side or the upper and lower ends of the right side of the cabinet 100, wherein the two door hinge assemblies 300 are respectively connected to the upper and lower ends of the corresponding side of the door panel 200; wherein, each door hinge assembly 300 includes a cantilever member 310 fixed to the front end face of the cabinet 100 and extending forward, and a transition member 320 fixed to the door panel 200 and rotatably connected to the extended end of the cantilever member 310.

[0025] The hinge mechanism described above uses the cantilever 310 to shift the axis of rotation between the door panel 200 and the cabinet 100 forward. The door panel 200 is rotatably connected to the cantilever 310 via the adapter 320 on the door panel 200 to achieve the opening and closing of the door panel 200. Assuming that the size of the embedded electrical equipment matches the recessed slot, because the axis of rotation of the door panel 200 relative to the cabinet 100 is shifted forward, the door panel 200 is still unlikely to touch the inner wall of the recessed slot when the opening angle is large, thus avoiding interference and improving practicality and ease of use.

[0026] See Figure 3 and Figure 5 In some embodiments of this utility model, one of the extended end of the cantilever member 310 and the adapter member 320 is provided with a pivot 410, and the other is provided with a shaft hole 420 that cooperates with the pivot 410. The projection of the outline edge of the door panel 200 in the front-rear direction is located within the outline edge of the cabinet 100. The distance between the axis of the pivot 410 and the front end face of the cabinet 100 is A, the distance between the axis of the pivot 410 and the front end face of the door panel 200 is B, and the distance between the axis of the pivot 410 and the adjacent side surface of the cabinet 100 is C, satisfying: 38 mm≤A≤42 mm, 11 mm≤B≤15 mm; 15 mm≤C≤17 mm. It is understandable that when the door panel 200 opens or closes the opening of the cavity 110, the adapter plate rotates relative to the end of the cantilever 310 through the cooperation of the pivot 410 and the shaft hole 420. The test shows that when the values ​​of A, B and C meet the above conditions, the opening angle of the door panel 200 relative to the cabinet 100 can reach between 105° and 115° without interference.

[0027] See Figure 3 and Figure 5In some embodiments of this utility model, the cantilever member 310 is an L-shaped sheet metal part. The L-shaped sheet metal part includes a vertical section 311 fixedly abutting against the front end face of the opening edge of the cavity 110 and a horizontal section 312 connected to the upper end of the vertical section 311. Neither the horizontal section 312 nor the vertical section 311 protrudes from the upper surface and adjacent side surface of the cabinet 100. It can be understood that using an L-shaped sheet metal part for the cantilever member 310 can reduce the occupation of height space, avoid significantly reducing the size specifications of the door panel 200 and the opening of the cavity 110, and the L-shaped sheet metal part is inexpensive and easy to manufacture.

[0028] See Figure 3 and Figure 4 In some embodiments of this utility model, the adapter 320 is a flat plate fixed to the top wall of the door panel 200, the flat plate abutting against the lower surface of the horizontal section 312, and an angle limiting mechanism is provided between the flat plate and the horizontal section 312. The use of a flat plate for the adapter 320 reduces the space occupied in height, is low-cost, and easy to manufacture; the angle limiting mechanism prevents the door panel 200 from being damaged due to excessive opening angle.

[0029] See Figure 3 and Figure 4 In some embodiments of this utility model, the angle limiting mechanism includes a blocking portion 510 bent upwards in the flat plate and a limiting groove 520 recessed in the side edge of the horizontal section 312. The blocking portion 510 rotates with the flat plate to abut against the bottom of the limiting groove 520 to limit the opening angle of the door panel 200. That is, the maximum angle at which the door panel 200 opens the cavity 110 is limited. At this time, the door panel 200 is close to the inner wall of the receiving groove without collision. Specifically, the blocking portion 510 is a bent plate, and the bent plate and the flat plate are sheet metal parts with an integral structure, which are formed by integral stamping. The limiting groove 520 is formed by punching on the horizontal section 312, which is very convenient to manufacture.

[0030] See Figure 5In some embodiments of this utility model, the L-shaped sheet metal part is made of stainless steel, and the thickness of the L-shaped sheet metal part is between 2.5mm and 3mm. The horizontal segment 312 is a rectangular plate, and the maximum width dimension of the rectangular plate is D. The distance between the bottom of the limiting groove 520 and one side edge of the rectangular plate is E, satisfying: E≥0.45D. It should be noted that the horizontal segment 312, as a cantilever structure, needs to meet certain mechanical strength requirements. The setting of the limiting groove 520 will also reduce the width dimension of the horizontal segment 312 at certain positions. After life test, when D and E meet the above dimensional conditions, the horizontal segment 312 will not bend or deform after the door panel 200 opens and closes the cavity 110 a preset number of times.

[0031] See Figure 3 and Figure 4 In some embodiments of this utility model, the door panel 200 includes an inner layer panel 210 and an outer layer panel 220 abutting the front surface of the inner layer panel 210. The inner layer panel 210 is used to open and close the opening of the cavity 110. The flat panel is mounted on the upper surface of the inner layer panel 210. The outline edge of the outer layer panel 220 and the outline edge of the cabinet 100 are projected in the front-rear direction. The outline edge of the outer layer panel 220 is located outside the outline edge of the inner layer panel 210 to cover the flat panel and the L-shaped sheet metal piece. This structure not only achieves a rotating connection between the door panel 200 and the cabinet 100, but also utilizes the outer layer panel 220 to cover the flat panel and the L-shaped sheet metal piece, thus achieving a concealing effect and providing a smooth appearance when the user looks at the embedded electrical equipment from the front.

[0032] See Figure 1 In some embodiments of this utility model, the inner layer plate 210 has a light-transmitting plate in the middle, and the outer layer plate 220 is a decorative frame plate in the shape of a square surrounding the light-transmitting plate. The four corners of the decorative frame plate are respectively installed to the outer periphery of the inner layer plate 210 by bolt assemblies. It can be understood that the user can observe the items placed in the cabinet 100 through the light-transmitting plate, while the decorative frame plate serves a decorative and concealing function. The decorative frame plate can also be installed and replaced by bolt assemblies. See Figures 3 to 5In some embodiments of this utility model, the end of the flat plate extends toward the outer layer plate 220. The outer layer plate 220 is provided with a relief groove 221 corresponding to the extended portion of the flat plate. The end of the flat plate is provided with a shaft hole 420. The end of the horizontal section 312 is provided with a pivot 410 passing through the shaft hole 420. A rubber washer 430 is sleeved on the outside of the pivot 410 and sandwiched between the horizontal section 312 and the flat plate. This structure allows the shaft hole 420 to be further adjusted to a more forward position, thereby further reducing the possibility of the door panel 200 being damaged when opened at a large angle. The rubber washer 430 reduces metal friction to achieve a silent operation.

[0033] This utility model also discloses an embedded electrical device, including the hinge mechanism of any of the above-mentioned technical solutions. Provided that the dimensions of the embedded electrical device match the recessed accommodating groove, because the axis of rotation of the door panel 200 relative to the cabinet 100 is offset forward, the door panel 200 is still unlikely to touch the inner wall of the recessed accommodating groove when the opening angle is large, thus avoiding interference problems.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
