[0029] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. However, the embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on the embodiments are all within the scope of protection of the present invention.

[0030] Please refer to Figures 1 to 5The figure shows an embodiment of the hinge assembly of the present invention, wherein the hinge assembly includes a hinge box 1, wherein the hinge assembly also includes a speaker 2 arranged in the hinge box 1 and a control panel 3 electrically connected to the speaker 2, the hinge box 1 includes a main body 11, a hinge shaft cover 12 extending forward from the main body 11, the main body 11 is formed with a hinge accommodating area 13 connected to the hinge shaft seat along the front-to-back direction, a speaker area arranged adjacent to the hinge accommodating area 13 in the transverse direction, and a control area 16 arranged adjacent to the hinge accommodating area 13 in the front-to-back direction.

[0031] In this embodiment, the hinge assembly is applied to refrigeration equipment, and is mainly applied to refrigerators in the refrigeration equipment. Of course, in other embodiments, the hinge assembly can also be applied to refrigeration equipment such as freezers, wine cabinets, and ice chests.

[0032] Specifically, the refrigeration device includes a housing and a door for opening or closing the housing. The main body 11 is disposed above the housing, and the hinge shaft cover 12 is disposed above the rotating shaft of the door. In this embodiment, the hinge assembly is disposed separately on one side of the housing. If the refrigerator is a double-door refrigerator, a hinge assembly can be disposed above each of the left and right doors, that is, two hinge boxes 1 can be provided. Of course, the left and right hinge boxes 1 can also be made into an integral structure, that is, a long strip structure extending in the horizontal direction.

[0033] In this embodiment, the hinge box 1 is arranged on the right side of the box body, and the sound-generating area includes a speaker accommodating area 14 and a sound-guiding structure 15 located in front of the speaker accommodating area 14. The speaker accommodating area 14 is arranged adjacent to the control area 16 in the lateral direction, and the sound-guiding structure 15 is arranged adjacent to the hinge accommodating area 13 in the lateral direction.

[0034] Therefore, the hinge box 1 is divided into four areas, including a hinge accommodating area 13 and a sound guide structure 15 located adjacent to each other in the transverse direction at the front side, and a control area 16 and a speaker accommodating area 14 located adjacent to each other in the transverse direction at the rear side. In addition, the speaker accommodating area 14 and the sound guide structure 15 are located outwardly relative to the control area 16 and the hinge accommodating area 13. Therefore, the above-mentioned zoning layout can make the hinge box 1 structure reasonably compact and reduce production costs.

[0035] In this embodiment, the main body 11 includes a top wall and four side walls extending downward from the top wall. The four side walls include a front side wall and a rear side wall disposed opposite each other, and a left side wall and a right side wall disposed opposite each other. The main body 11 also includes a first extension 17 extending outward from the bottom of the rear side wall and a second extension 18 extending outward from the bottom of one of the two lateral walls distal from the hinge shaft cover 12. The first extension 17 extends rearward, and the second extension 18 extends leftward. Therefore, the right side wall of the main body 11, which is closest to the outside, is vertical and does not protrude outward, thereby ensuring the overall aesthetics of the refrigeration device.

[0036] In this embodiment, the main body 11 also includes a partition wall 19 protruding downward and arranged between the control panel 3 and the speaker 2, and the partition wall 19 extends in the front-to-back direction, wherein the partition wall 19 and the left side wall form the speaker accommodating area 14, and the partition wall 19 and the right side wall form the control area 16, and the control area 16 is connected to the hinge accommodating area 13 in the front-to-back direction.

[0037] The hinge assembly includes a pre-positioning structure and a positioning structure arranged between the main body 11 and the control panel 3. The pre-positioning structure includes a limiting portion 111 protruding downward from the main body 11 and located in front and behind the control panel 3, a guide column 112 protruding from the main body 11, and a guide hole 31 arranged on one side of the control panel 3 and cooperating with the guide column 112.

[0038] Specifically, the control board 3 is rectangular in shape, with the guide post 112 positioned at a corner of one side of the control board 3 along the transverse direction. A pair of stoppers 111 are staggered along the transverse direction. Therefore, the main control board can be pre-positioned solely using the guide post 112 and stoppers 111, resulting in a simple structure. Furthermore, since the stoppers 111 are ribbed, they are smaller than the guide posts 112, thereby reducing production costs. In other embodiments, the guide posts 112 can also be configured as multi-faceted structures, thereby achieving single-point fixation.

[0039] The positioning structure includes a positioning column 113 protruding downward from the main body 11, a fixing hole recessed upward from the fixing column 115, a positioning hole 32 arranged on one side of the control panel 3, and a fixing member 4 fixing the fixing hole and the positioning hole 32. The hinge assembly includes a pair of the fixing structures arranged at the diagonal corners of the control panel 3, and the pair of the fixing structures are respectively arranged on both sides of the control panel 3 in the horizontal direction.

[0040] The positioning holes 32 and the guide holes 31 are respectively arranged at three corners of the control board 3, and the guide holes 31 are close to the right side wall of the main body 11 and arranged on the front side of the control board 3, so that the structure on the left side of the control board 3 is less, which is convenient for wiring.

[0041] The main body 11 has a heat dissipation hole 114 that passes through its side wall to dissipate heat from the control board 3. In this embodiment, the heat dissipation hole 114 is set to pass through the rear side wall of the main body 11 in the front-to-back direction, which not only facilitates heat dissipation but also improves the overall aesthetics.

[0042] The hinge assembly also includes a mounting structure arranged between the main body 11 and the speaker 2, the mounting structure including a fixing column 115 protruding from the main body 11, a fixing plate 21 protruding from both sides of the speaker 2 in the lateral direction, and a screw fixing the fixing column 115 and the fixing plate 21, the fixing plate 21 having a through hole for the screw to pass through, the mounting structure also includes a buffer washer 5 arranged in the through hole, the buffer washer 5 having a first buffer portion clamped between the screw and the fixing plate 21, and a second buffer portion clamped between the fixing plate 21 and the fixing column 115.

[0043] By providing the buffer gasket 5, the vibration between the speaker 2 and the hinge box 1 during operation can be effectively reduced, thereby reducing noise. In this embodiment, the fixing column 115 is formed to extend in the front-to-back direction. Of course, in other embodiments, the fixing column 115 can also be formed to extend in the height direction.

[0044] In this embodiment, the sound-guiding structure 15 is a recessed portion arranged on the front side of the speaker 2 and recessed downward from the hinge box 1. The recessed portion has two side walls perpendicular to the top wall of the hinge box 1 and arranged in the transverse direction, a rear side wall connecting the two side walls, and a bottom wall connecting the two side walls and the rear side wall. The bottom surface height of the bottom wall is gradually extended upward from the back to the front, and at least one of the two side walls of the recessed portion along the transverse direction is offset and extended outward, and the offset angle range is 1-5°.

[0045] The above arrangement ensures that the speaker 2 can smoothly transmit sound forward directly to the user, facilitating human-computer interaction. In this embodiment, the left and right walls of the recessed portion are offset outward, resulting in a slightly diffuse sound overall, preventing muffled sound. Furthermore, the sound propagation direction is primarily forward, further facilitating sound transmission to the user. The bottom wall of the recessed portion is a curved surface structure that gradually extends upward from back to front, also facilitating forward sound transmission. The noise reduction structure 6 is also provided on the lower surface of the bottom wall of the recessed portion.

[0046] The main body 11 has a sound outlet portion 116 disposed in front of the sound outlet position of the speaker 2. The sound outlet portion 116 has a plurality of sound outlet holes 117 for the speaker 2 to emit sound. In this embodiment, the sound outlet portion 116 is the rear side wall of the recessed portion.

[0047] The hinge box 1 also has a drainage hole 118 extending transversely through the sidewall of the recessed portion and a through hole 119 extending transversely through its outer wall. The through hole 119 communicates with the drainage hole 118 to drain water from the recessed portion to the outside of the hinge box 1. In this embodiment, the drainage hole 118 extends through the left sidewall of the recessed portion, while the through hole 119 extends through the left sidewall of the main body 11. This prevents water from flowing toward the control board 3, reducing the risk of damage to the control board 3.

[0048] The hinge box 1 also has a through-slot 120 extending through the bottom wall of the recessed portion. This through-slot 120 connects the drainage hole 118 and the sound outlet 116. Specifically, the through-slot 120 is located in front of the sound outlet 116. Therefore, when moisture accumulates within the sound-guiding structure 15, it flows along the bottom wall of the recessed portion into the through-slot 120 and then out of the hinge box 1 through the drainage hole 118 and through-hole 119.

[0049] The hinge box 1 also has a shielding portion 121 protruding forward from its upper surface to the front side of the sound outlet 116. The shielding portion 121 can prevent water above the hinge box 1 from flowing directly to the sound outlet 116, thereby reducing the risk of moisture entering the speaker 2 through the sound outlet 116.

[0050] In this embodiment, the forward extension length of the shielding portion 121 is smaller than the width of the through groove 120 along the front-to-back direction. Therefore, when water flows along the shielding portion 121 , it can directly flow into the through groove 120 , thereby improving the drainage effect.

[0051] The hinge assembly also includes a wiring harness (not shown) respectively connected to the control board 3 and the speaker 2. The wiring harness includes a wiring harness body and a terminal plug-in portion connected to the end of the wiring harness body. A storage space for accommodating the wiring harness and an outlet connected to the storage space for wire outlet are respectively formed between the partition wall 19 and the control board 3, and between the partition wall 19 and the speaker 2.

[0052] In this embodiment, the main body 11 further includes a first harness portion 122 located at the front of the housing space to secure the wiring harness for the control board 3, and a second harness portion 123 to secure the wiring harness for the speaker 2. The first harness portion 122 guides the wiring harness extending from the control board 3 forward along the first harness portion 122, while the second harness portion 123 allows the wiring harness extending from the speaker 2 to be wrapped around the second harness portion 123. This shifts the stress points between the first harness portion 122 and the second harness portion 123, thereby protecting the wiring harness from stress and damage caused by pulling.

[0053] Among them, the first wiring harness portion 122 is arranged on the front side of the partition wall 19 and is arranged between the control board 3 and the partition wall 19 in the transverse direction. The first wiring harness portion 122 includes a first portion extending in the transverse direction, a second portion extending in the front-to-back direction, and an arc-shaped guide portion connecting the first portion and the second portion.

[0054] Specifically, the first portion is connected to the positioning column 113, thereby strengthening the structural strength of the two as a whole and making them less susceptible to damage. The second portion extends forward from the arc-shaped guide portion, thereby preventing the wiring harness body from contacting sharp corners during winding, reducing the chance of damage. At the same time, the damaged arc-shaped guide portion can also facilitate the forward extension of the wiring harness body. Secondly, the first and second portions are sheet-like structures, requiring less material, which can reduce production costs. Moreover, when the wiring harness body of the control board 3 is pulled forward, the first wiring harness portion 122 can serve as a force point to offset part of the force and reduce the risk of damage. Of course, in other embodiments, the first wiring harness portion 122 can also be a columnar structure, and can further be set to a cylindrical shape.

[0055] The longer length in the transverse direction can also effectively reduce the number of winding turns and improve winding efficiency. Of course, in other embodiments, the damaged first wire bundle portion 122 can also be a columnar structure, and can further be set to a cylindrical shape.

[0056] In this embodiment, the second harness portion 123 is disposed in front of the first harness portion 122. The second harness portion 123 comprises a horizontal portion extending transversely and a hook portion extending upward from the distal end of the horizontal portion. The harness for the control board 3 extends from the first harness portion 122, fixedly extending over the horizontal portion. The harness for the speaker 2 is wrapped around the horizontal portion, allowing the speaker 2 and control board 3 terminal connectors to interface with other structures in front of the second harness portion 123. The hook portion prevents the harness from escaping transversely from the horizontal portion, ensuring an orderly arrangement of the harness.

[0057] To reduce the noise generated by the operating vibration of the speaker 2, the hinge assembly further includes a noise reduction structure 6 disposed below the main body 11. In this embodiment, the noise reduction structure 6 is foam or sponge. Of course, in other embodiments, the noise reduction structure 6 can also be other buffering and shock-absorbing materials.

[0058] Specifically, in this embodiment, the noise reduction structure 6 is disposed below the first extension 17, the second extension 18, the partition wall 19, and the sound-guiding structure 15, thereby surrounding the speaker 2. The first extension 17, the second extension 18, and the partition wall 19 each have a limit groove 124 recessed upward from their lower surfaces, with the depth of the limit groove 124 in the height direction being less than the thickness of the noise reduction structure 6.

[0059] Therefore, by providing the limiting groove 124, it is possible to easily install and fix the noise reduction structure 6. In addition, the height of the limiting groove 124 is less than the thickness of the noise reduction structure 6, thereby reducing the risk of the first extension portion 17, the second extension portion 18 and the partition wall 19 directly contacting the top of the box body, thereby reducing the vibration between the above structure and the box body and reducing noise.

[0060] In this embodiment, the depth of the limiting groove 124 in the height direction is less than half the thickness of the noise reduction structure 6, so that when the hinge box 1 is completely fixed on the box body, the first extension part 17, the second extension part 18 and the partition wall 19 will not directly contact the top of the box body, thereby effectively avoiding vibration between the box body and reducing noise.

[0061] The main body 11 also includes a protrusion 125 protruding from the inner wall of the right side wall in the lateral direction, and the protrusion 125 includes a first protrusion and a second protrusion arranged in the front and rear, and a third protrusion arranged between the first protrusion and the second protrusion. The first protrusion and the second protrusion extend in the height direction, and the third protrusion extends in the front and rear direction. The lower ends of the first protrusion, the second protrusion and the third protrusion are higher than the lower end of the side wall.

[0062] The noise reduction structure 6 is also provided on the protrusion 125. The noise reduction structure 6 includes a first noise reduction portion attached to the front surface of the first protrusion, a second noise reduction portion attached to the rear surface of the second protrusion, and a third noise reduction portion connecting the first and second noise reduction portions and attached to the lower surface of the third protrusion. This further reduces vibration between the right side wall and the box body, thereby reducing noise.

[0063] In addition, the noise reduction structure 6 is also arranged on the upper and lower surfaces of the speaker 2, so that the noise reduction structure 6 and the buffer gasket 5 cooperate with each other, avoiding direct contact between the speaker 2 and the hinge box 1, effectively avoiding vibration between the hinge box 1 and reducing noise.

[0064] Not only that, the hinge assembly also includes a noise reduction structure 6 arranged on the front side of the first wiring harness portion 122 and the second wiring harness portion 123 and cooperated with the terminal plug-in portion, specifically arranged on the front side of the second wiring harness portion 123. The noise reduction structure 6 is foam or sponge, so that the terminal plug-in portion is arranged below the noise reduction structure 6 to avoid direct contact between the terminal plug-in portion and other structures to generate noise.

[0065] In this embodiment, the hinge box 1 also has a mounting portion 126 that continues to extend backward from the first extension portion 17 of the main body 11, a first mounting hole 127 that penetrates the mounting portion 126 along the height direction, a second mounting hole 128 that penetrates the bottom wall of the recessed portion along the height direction, and a third mounting hole 129 that penetrates the top wall of the main body 11 along the height direction. The third mounting hole 129 is located at the hinge accommodating area 13. The hinge box 1 can be fixed to the box body through the first mounting hole 127, the second mounting hole 128 and the third mounting hole 129.

[0066] like Figures 6 to 10 As shown, the door of the refrigeration appliance also has a lower trim strip 7 located on its underside and a microphone assembly 8 mounted on the lower trim strip 7. The microphone assembly 8 is electrically connected to the hinge assembly via a door cable, thereby enabling interaction between the microphone assembly 8 and the speaker 2, thereby achieving human-computer interaction. Furthermore, in this embodiment, the microphone assembly 8 is located on the lower trim strip 7, making it less noticeable to the user and effectively improving the aesthetics. Of course, in other embodiments, the microphone assembly 8 can also be located on the upper trim strip of the door.

[0067] Specifically, the microphone assembly 8 is extended along the transverse direction, and the microphone assembly 8 includes an installation box 81, a microphone 82 arranged in the installation box 81, and a cover plate 83 fixed to the installation box 81. The door body also includes a retaining structure arranged between the lower decorative strip 7 and the microphone assembly 8, and the retaining structure includes a card slot 71 and a fastening hole 76 arranged on the lower decorative strip 7 and spaced apart along the transverse direction, a retaining portion 88 and a matching hole 89 arranged on both sides of the cover plate 83 and respectively matching with the card slot 71 and the fastening hole 76, and a screw matching with the fastening hole 76 and the matching hole 89.

[0068] Therefore, by providing a holding portion 88 on one side of the cover plate 83 and a matching hole 89 on the other side, not only can the microphone assembly 8 be quickly installed, but it can also be firmly fixed.

[0069] In this embodiment, the lower trim strip 7 has a fixing surface 72 that is recessed upward from its lower surface, and a mounting space 73 that is further recessed from the center of the fixing surface 72. The microphone assembly 8 is fixed to the fixing surface 72. The inner wall of the mounting space 73 along one side of the transverse direction is further recessed to form the slot 71 with the bottom wall of the lower trim strip 7. The mounting space 73 can be used to accommodate structures such as docking terminals or wiring harnesses.

[0070] The projection of the microphone assembly 8 in the height direction is generally rectangular, and therefore the mounting space 73 is also generally rectangular. The fixing surfaces 72 are respectively provided on the front and rear sides and one side in the lateral direction of the mounting space 73, and the fastening hole 76 is provided on the fixing surface 72 on one side in the lateral direction, thereby facilitating fastening to the cover 83. Because the retaining groove 71 is formed by the bottom wall of the lower decorative strip 7 and the mounting space 73 above it, when the retaining portion 88 engages with the retaining groove 71, the retaining portion 88 actually abuts the upper surface of the bottom wall of the lower decorative strip 7.

[0071] In this embodiment, the bottom wall of the lower trim strip 7 also has a rib 74 protruding upward from the bottom wall of the lower trim strip 7. The retaining portion 88 abuts against the bottom of the rib 74. The provision of the rib 74 strengthens the bottom wall structure of the lower trim strip 7 and reduces the risk of damage. The rib 74 also has a guiding slope 75 that facilitates the retaining portion 88's insertion above the rib 74. This facilitates the installation of the retaining portion 88.

[0072] In this embodiment, the mounting box 81 is trapezoidal in shape along the front-to-back direction, and has a receiving cavity for receiving the microphone 82 and an opening facing rearward. The microphone assembly 8 includes a pair of microphones 82 spaced apart in the transverse direction and disposed in the receiving cavity.

[0073] The cover plate 83 includes a first fixing portion 85 that extends vertically and is secured to the opening of the mounting box 81, and a second fixing portion 86 that is connected to the first fixing portion 85 and secured to the fixing surface 72 of the lower trim strip 7. The cover plate 83 also includes several reinforcing portions 87 that connect the first fixing portion 85 and the second fixing portion 86. The mounting box 81 protrudes from the lower end of the lower trim strip 7. The retaining portion 88 and mating hole 89 are provided on the second fixing portion 86. Therefore, the mounting box 81 protruding from the lower end of the lower trim strip 7 facilitates clearer reception of user voices, improving the efficiency of human-computer interaction.

[0074] To sum up, the hinge assembly of the present invention rearranges the hinge box 1, specifically including three major areas: the hinge accommodating area 13, the control area 16 and the speaker area, so that the hinge box 1 has a compact and reasonable structure, a small size and a low cost. At the same time, it also has a speaker function, which can realize voice playback and improve user experience.

[0075] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
