The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0036] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The door of a household appliance refers to a mechanical structure used to protect the internal equipment of the appliance and provide access to the appliance. It is usually made of a single and solid metal or plastic material to protect the appliance from the external environment. In addition, the door should also have dustproof, waterproof, fireproof and other protective properties to ensure the safe operation of the internal structure of the appliance.

[0039] The door body generally also has a safety locking function, and only authorized personnel can open or close the nursing machine door. This can ensure the safety of the equipment inside the nursing machine and prevent unauthorized personnel from accessing the equipment inside the nursing machine.

[0040] However, in a high temperature environment, the plastic door of the existing household appliances tends to deform, which affects the stability and safety of the door structure and also affects the normal use of the door. Therefore, the present invention proposes the following technical solution.

[0041] like Figure 1-2 As shown, the present invention provides a door body structure, including an outer shell 1 and a support plate, the support plate includes a support inner plate 2 and a support outer plate 3, the outer shell 1 is installed on the outer side of the support outer plate 3, the support inner plate 2 and the support outer plate 3 are respectively installed on both side surfaces of a support frame 4, and the support frame 4 and the connected reinforcement 10 form a double parallel four-bar skeleton structure to stably support the outer shell 1 and the support plate.

[0042] It is understandable that the outer shell 1 of the door structure refers to the outer part of the door, which is used to protect and decorate the structure of the door. Optionally, the outer shell 1 can be made of any one of wood, metal, plastic, etc., and technicians in this field can specifically select the material for preparing the outer shell 1 according to the use environment and requirements of the door. Preferably, the outer shell 1 in the present application is a metal outer shell 1, and the outer shell 1 is detachably mounted on the outer side of the supporting outer plate 3.

[0043] Further, the housing 1 is detachably connected to the supporting outer plate 3, and the detachable connection includes any one of a threaded connection, a plug-in connection, a snap connection, a fixing connection, etc. Preferably, in the embodiment of the present application, the housing 1 is snap-connected to the supporting outer plate 3.

[0044] Furthermore, the housing 1 can also be equipped with different accessories as needed, such as door locks, door handles 8, door hinges, etc., to increase the safety and convenience of the door structure.

[0045] The support plate of the door structure is a supporting structure installed on the door body to enhance the stability and load-bearing capacity of the door body. It is usually made of steel, iron or other solid materials. The support plate can not only increase the structural strength of the door body, but also avoid deformation, sagging and other problems of the door body, ensuring the normal use of the door body and extending the service life of the door body.

[0046] The support plate in the application of the present invention includes a support inner plate 2 and a support outer plate 3, the outer shell 1 is installed on the outer side of the support outer plate 3, the support inner plate 2 and the support outer plate 3 are respectively installed on the two side surfaces of the support frame 4, the support frame 4 and the connected reinforcement 10 constitute a double parallel four-bar skeleton structure to stably support the outer shell 1 and the support plate, the support frame 4 and the support plate together constitute a stable support for the door body structure, and the support frame 4 and the connected reinforcement 10 constitute a double parallel four-bar skeleton structure, which makes the door body not easy to deform and enhances the stability of the door body structure.

[0047] Furthermore, the supporting inner plate 2 and the supporting outer plate 3 are both made of ACM plates, and the supporting inner plate 2 and the supporting outer plate 3 are installed on the supporting frame 4 by bonding or fixing parts.

[0048] It is easy to understand that ACM, also known as advanced composite materials, refers specifically to composite materials that can be used to process primary and secondary load-bearing structures with stiffness and strength equivalent to or greater than that of aluminum alloys. The plates made from it have the characteristics of corrosion resistance, heat insulation, sound insulation, shock absorption, and high temperature resistance. They are widely used in aerospace, medicine, machinery, construction, home appliances and other industries.

[0049] The above-mentioned supporting inner panel 2 and supporting outer panel 3 are both made of ACM panels, ensuring that the door structure has the advantages of corrosion resistance, heat insulation, shock absorption, high temperature resistance, etc. after installation, thereby improving the performance of the door structure, extending its service life, and enhancing the user experience.

[0050] The inner support plate 2 and the outer support plate 3 are connected to the support frame 4 by bonding or fixing parts, and the inner support plate 2 and the outer support plate 3 are respectively placed on the front and back sides of the double parallel four-bar skeleton structure formed by the support frame 4.

[0051] The double parallel four-bar frame structure includes mutually parallel support frames 4 and mutually parallel reinforcement members 10, the reinforcement members 10 and the support frames 4 are perpendicular to each other, and the reinforcement members 10 and the support frames 4 are connected by fixing members. Preferably, the fixing members are fixing screws, and each connection between the reinforcement member and the support frame 4 is provided with a plurality of fixing screws, and the plurality of fixing screws are installed to form a stable triangular shape.

[0052] Specifically, the double parallel four-bar frame structure includes two mutually parallel support frames 4 and two mutually parallel reinforcement members 10, the reinforcement members 10 are perpendicular to the support frames 4, and the reinforcement members 10 are connected to the support frames 4 via a fixing member. In addition, those skilled in the art can also make other equivalent or similar substitutions for the double parallel four-bar frame structure, for example, two groups of mutually parallel support frames 4 and two groups of mutually parallel reinforcement members 10 are provided in the double parallel four-bar frame structure, and the number of each group of support frames 4 and reinforcement members 10 can be specifically selected and designed according to the requirements of the support strength.

[0053] Furthermore, the fixing member is a fixing screw, and three fixing screws are provided at the connection between each reinforcement member 10 and the support frame 4. The three fixing screws form a stable triangular shape, further enhancing the stability and supporting strength of the double parallel four-bar skeleton structure.

[0054] As attached Figure 2As shown, in the double parallel four-bar frame structure, two mutually parallel support frames 4 include a first support frame 41 and a second support frame 42, and two mutually parallel reinforcement members 10 include a first reinforcement member 101 and a second reinforcement member 102. During the installation process, the first support frame 41, the first reinforcement member 101, the second support frame 42, and the second reinforcement member 102 are connected in sequence, and the support frame 4 and the reinforcement member 10 are used as mutually perpendicular adjacent sides. The first support frame 41 is parallel to the second support frame 42, and the first reinforcement member 101 is parallel to the second reinforcement member 102. The installed double parallel four-bar frame structure is a rectangle with a hollow middle part. The connection between the support frame and the reinforcement member 10 is connected by a fixing member, and the fixing member is preferably a fixing screw, and each connection is provided with 3 fixing screws, and the 3 fixing screws are in a stable triangle. The design of the triangular fixing structure makes the double parallel four-bar frame structure more stable and reliable, and at the same time makes the door body structure stable and not deformed.

[0055] As a possible embodiment of the present invention, the door body structure further includes a door sealing groove 7, which is plug-in connected to the support frame 4, and the plug-in installed door sealing groove 7 is press-fitted with the support inner plate 2 and the outer shell 1.

[0056] The door sealing groove 7 is a groove structure for installing a door seal. The present invention application does not limit the specific structure of the door sealing groove 7. Technicians in this field can choose to design the specific structure of the door sealing groove 7 according to the shape of the door seal. It is only necessary to ensure that the structure of the door sealing groove 7 matches and adapts to the structure of the door seal to be installed.

[0057] Preferably, the door sealing groove 7 of the present application is provided with a slot body for installing the door sealing strip as well as an insertion strip for stable installation, and the first support frame 41 and the second support frame 42 are both provided with slots for matching the insertion strips. When installing the left door sealing groove 7 or the right door sealing groove 7, the insertion strip can be inserted into the slot on the first support frame 41 or the second support frame 42, thereby realizing a stable connection between the door sealing groove 7 and the support frame 4.

[0058] The door sealing groove 7 is also provided with a first groove side plate and a second groove side plate which are respectively crimped with the supporting inner plate 2 and the outer shell 1. Specifically, the first groove side plate is crimped with the supporting inner plate 2, and after the first groove side plate is crimped onto the supporting inner plate 2, it is fixed with screws. The second groove side plate is crimped onto the outer shell 1 of the door structure, and the connection between the outer shell 1 of the door structure and the second groove side plate is a right-angled structural design in cross section, thereby forming a groove body crimped with the second groove side plate, and the second groove side plate is reinforced and fixed with screws after being crimped onto the outer shell 1. Optionally, after the groove side plates in the present application are crimped with the supporting inner plate 2 and the outer shell 1, screws are used as fasteners for reinforced fixation. Technicians in this field can also choose other fasteners for equivalent or similar substitutions, as long as the function of reinforced fixation can be achieved.

[0059] It is understandable that the specific shapes of the first groove side plate and the second groove side plate can be selected and designed according to the structural shape of the crimping point. Preferably, the first groove side plate and the second groove side plate are strip-shaped rectangular parallelepipeds.

[0060] The door seal groove 7 is provided with a door seal strip, which can prevent dust, noise, cold air or insects from entering the cavity of the electrical equipment. The door seal strip includes a variety of types such as a rubber strip type, a brush strip type, and a magnetic strip type, and technicians in this field can choose according to specific needs.

[0061] As an embodiment of the present invention, an upper decorative panel 5 and a lower decorative panel 6 are installed at both ends of the door structure, and the upper decorative panel 5 and the lower decorative panel 6 are detachably connected to the two ends of the door structure respectively.

[0062] The upper decorative plate 5 and the lower decorative plate 6 are horizontal or vertical strip decorative plates, which are used to increase the beauty and decorative effect of the door structure, and can also effectively prevent the wear of the door ends. The decorative plates are usually arranged at the upper and lower parts of the door structure, covering the upper and lower edges of the door structure respectively. Preferably, in the present application, the upper decorative plate 5 and the lower decorative plate 6 are respectively connected to the two ends of the door structure and fastened by screws.

[0063] Furthermore, the door structure in the present invention further includes a main control panel assembly 9 , which is installed in the support frame 4 , and the main control panel assembly 9 is snap-connected to the support frame 4 .

[0064] The main control panel assembly 9 is responsible for controlling the switch, safety protection and other functions of the door body. Generally, the main control panel assembly 9 includes the following component modules: controller, power module, communication interface, motor driver, safety protection device, control button and display screen, memory.

[0065] Specifically, the controller is responsible for receiving and processing signals from the sensor, and performing corresponding door operations according to the preset logic; the power module can provide power to the main control board and other related components to ensure the normal operation of the door system; the communication interface is used to interact with other external devices or systems, such as connecting with access control systems, alarm systems, etc.; the motor driver controls the motor of the door switch, and implements opening, closing, stopping and other operations as required; the safety protection device includes sensors, limit switches, reverse control, etc., which are used to monitor the status and position of the door and ensure safe operation; the control buttons and display screen provide a user interface for manually controlling the opening and closing of the door and displaying the system status and fault information; the memory is used to store configuration parameters, log records, fault diagnosis information, etc.; the various component modules work in coordination to enable the door to operate safely and stably.

[0066] Furthermore, a buckle assembly for installing the main control board assembly 9 is provided on the support frame 4, and the main control board assembly 9 is connected to the support frame 4 through the buckle assembly. Furthermore, the buckle assembly includes one or more buckles for connecting and fixing. Preferably, the buckle assembly in the present application includes 9 buckles, and the 9 buckles are evenly distributed at the connection between the main control board assembly 9 and the support frame 4. The setting of the buckle makes the main control board assembly 9 stable after installation, can operate safely and stably, and is also convenient for users to disassemble and maintain.

[0067] The present invention application also proposes a method for installing a door structure, the method comprising the following steps:

[0068] S1, connecting and fixing the support frame 4 and the reinforcement member 10 to form a double parallel four-bar skeleton structure;

[0069] S2. Install the inner support plate 2 and the outer support plate 3 on the two sides of the support frame 4 respectively through tooling positioning;

[0070] S3, installing the outer shell 1 of the door structure on the outside of the supporting outer panel 3, and then installing the door sealing groove 7 on the left and right sides of the door structure and installing the upper decorative panel 5 and the lower decorative panel 6 on the upper and lower ends of the door structure;

[0071] S4, sequentially install the door body frame 12, the upper and lower pressure strips 11 and the door seal;

[0072] S5, sliding the door handle 8 into the preset handle groove and fixing it with fasteners;

[0073] S6. Finally, install the main control board assembly 9 and insert the main control board assembly 9 into the support frame 4 to save installation space and facilitate disassembly and assembly.

[0074] Further, in step S1, the double parallel four-bar frame structure includes two mutually parallel support frames 4 and two mutually parallel reinforcement members 10, the reinforcement members 10 and the support frames 4 are perpendicular to each other, and the reinforcement members 10 and the support frames 4 are connected by fixing members. At the same time, three fixing members are provided at each connection between the reinforcement member 10 and the support frame 4, and the three fixing members form a triangular structure, so that each connection between the reinforcement member 10 and the support frame 4 is provided with a triangular reinforcement structure, which enhances the stability of the double parallel four-bar frame structure, can effectively prevent the deformation of the door body structure, and prolong the service life.

[0075] In step S2, the double parallel four-bar skeleton structure is fixed by tooling positioning, and then the support inner plate 2 is installed on the inner side of the support frame 4. After the support inner plate 2 is installed, the double parallel four-bar skeleton structure is flipped 180°, and the support outer plate 3 is installed on the outer side of the support frame 4, thus completing the installation of the support inner plate 2 and the support outer plate 3.

[0076] Furthermore, before installing the door sealing groove 7, the door body structure needs to be flipped to the side opposite to the outer shell 1, and the left door sealing groove 7 and the right door sealing groove 7 are respectively inserted into the support frame 4 at an angle, and then the left door sealing groove 7 and the right door sealing groove 7 are rotated and laid flat to crimp and tighten the support plate and the outer shell 1.

[0077] The left door sealing groove 7 is press-fitted with the support plate and the left side of the housing 1, and after the press-fitting is completed, fasteners are used to strengthen the fixation; the right door sealing groove 7 is press-fitted with the support plate and the right side of the housing 1, and after the press-fitting is completed, fasteners are also used to strengthen the fixation. The fasteners can be the same or similar structural parts with fixing functions such as screws and bolts.

[0078] After the upper decorative plate 5 and the lower decorative plate 6 are installed, the door inner frame 12, the upper and lower pressure strips 11 and the door seal are installed in sequence. Preferably, when installing the door inner frame 12, the door inner frame 12 is snap-connected with the door seal groove 7. Those skilled in the art may also use other connection methods such as threaded connection for equivalent or similar substitution.

[0079] After the door inner frame 12 is installed, the bead 11 is generally installed at the upper and lower edges of the outer side of the door inner frame 12. The specific installation position of the bead 11 can also be changed according to different door structures and design requirements. Further, after the upper and lower bead 11 are installed, they are fastened with fixing screws. The lower bead 11 is fastened together with the door inner frame 12. The arrangement of the bead 11 can increase the stability of the door structure and prevent it from shaking or structural deformation.

[0080] In step S5, when installing the door handle 8, the door structure needs to be turned over to the front, the door handle 8 is placed in the corresponding installation slot, and then slid down to the edge of the housing 1, and finally tightened with screws. Optionally, the door handle 8 can be installed not only in an embedded manner but also in an external convex manner. Compared with the external convex door handle 8, the embedded door handle 8 not only saves space, but also is not easy to cause scratches to the user, thus avoiding unnecessary harm to the human body.

[0081] During the installation of the main control board assembly 9 in step S6, the main control board assembly 9 is snap-fitted and embedded in the corresponding installation position of the support frame 4. A buckle assembly for fixing the main control board is installed in the support frame 4, and the buckle assembly includes one or more buckles for connection and fixing. Preferably, the buckle assembly in the present application includes multiple buckles, and the multiple buckles are evenly distributed at the connection between the main control board assembly 9 and the support frame 4. Further preferably, the multiple buckles are 9 buckles. The setting of the buckle assembly makes the main control board assembly 9 stable after installation, can operate safely and stably, and is also convenient for users to disassemble and maintain.

[0084] The support frame 4 and the connected reinforcement 10 form a double parallel four-bar skeleton structure to stably support the outer shell 1 and the support plate. The reinforcement 10 and the support frame 4 are connected by fixings. The connection on each side is fastened with three fixings. The fastening points of the three fixings form a triangular fixing area, making the double parallel four-bar skeleton structure more stable and reliable, thereby enhancing the compressive strength and stability of the door structure.
