Description

Technical Field

[0001] This application relates to the field of home appliances, and more particularly to an installation fixture for the door panel of an embedded refrigeration device. Background Technology

[0002] In recent years, as people's demands for the integration of aesthetics and functionality in their home spaces have increased, built-in appliances have gradually become a mainstream choice. Especially in modern kitchen design, fully integrated refrigerators are increasingly favored by consumers due to their excellent integrated effect. A fully integrated refrigerator refers to a refrigerator whose body is completely embedded in the cabinetry, with the front panel matching the cabinet doors, creating a unified and simple visual style.

[0003] During the installation of a fully integrated refrigerator, to achieve a neat alignment between the door and the cabinet door, the decorative door panel usually needs to be installed onto the refrigerator door using a connecting structure. In existing technology, the installation steps typically include multiple steps such as measuring, marking, positioning, drilling, and screw fixing of the connectors. This process is cumbersome and requires a high level of experience and skill from the installers.

[0004] In actual installation, if there are errors in the positioning of the connectors on the door panel, it may result in uneven gaps between the refrigerator door and the door panel after assembly, affecting the overall appearance harmony. In addition, traditional positioning methods require high precision in marking, which is not only inefficient, but also affects subsequent fine-tuning of the door panel position and reinstallation if errors occur, and may even lead to the scrapping of the entire panel, resulting in resource waste and increased costs.

[0005] Therefore, there is an urgent need for a door panel installation solution that is simple in structure, highly accurate in positioning, easy to operate, and cost-effective, in order to improve the installation efficiency and assembly quality of embedded refrigerator door panels.

[0062] The present patent will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present patent, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of this patent.

[0063] Reference Figure 1 and Figure 2 This application provides an embedded refrigeration device 1. The embedded refrigeration device 1 includes a refrigeration device 2. The refrigeration device 2 can be a refrigerator or freezer, etc. The refrigeration device 2 includes a cabinet 21. A storage compartment is formed inside the cabinet 21. The storage compartment can be a refrigerator compartment, a freezer compartment, or a variable temperature compartment, etc. The embedded refrigeration device 1 can include a door 22. The door 22 is installed on the cabinet 21 and is used to open and close the storage compartment. The door 22 can be pivotally installed on the cabinet 21 via a hinge structure, or it can be pulled out and installed on the cabinet 21 via a pull-out structure.

[0064] The embedded cooling device 1 also includes a cabinet 3. The cabinet 21 is embedded within the cabinet 3. The embedded cooling device 1 also includes a door panel 31 and a fastener 4. The fastener 4 connects the cabinet door 22 and the door panel 31, allowing the door panel 31 to cover the exterior surface of the cabinet door 22. The appearance of the door panel 31 is consistent with the appearance of the cabinet 3. Because the cabinet 21 is embedded within the cabinet 3, and the door panel 31 covers the exterior surface of the cabinet door 22, a consistent and aesthetically pleasing overall appearance is achieved for the embedded cooling device 1.

[0065] A refrigeration unit 2 may have multiple storage compartments, and correspondingly, a refrigeration unit 2 may have multiple doors 22. For example, the refrigeration unit 2 may include a refrigerator compartment and a refrigerator door 221 for opening and closing the refrigerator compartment, and the refrigeration unit 2 may also include a freezer compartment and a freezer door 222 for opening and closing the freezer compartment.

[0066] To cover each of the doors 22 of the refrigeration unit 2, the embedded refrigeration unit 1 includes a door panel 31 corresponding to each door 22. For example, the embedded refrigeration unit 1 may include a refrigerator door panel 311 for covering the exterior of the refrigerator door 221, and the embedded refrigeration unit 1 may also include a freezer door panel 312 for covering the exterior of the freezer door 222.

[0067] The cabinet door 22 may include a first cabinet door 223 and a second cabinet door 224. The door panel 31 may include a first door panel 313 and a second door panel 314. The fastener 4 may include a first fastener 43 and a second fastener 44. The first fastener 43 is used to connect the first cabinet door 223 and the first door panel 313. The second fastener 44 is used to connect the second cabinet door 224 and the second door panel 314.

[0068] For ease of description, in this application, the thickness direction of the door panel 31 is the front-to-back direction, with the outer surface of the door panel 31 facing forward. The cabinet door 22 is located on the rear side of the door panel 31, and the rear wall of the door panel 31 is opposite to the front wall of the cabinet door 22. The height direction of the door panel 31 is the up-down direction, which is consistent with the height direction of the cabinet body 21, cabinet body 3, etc., with the direction of gravity being downward and the opposite direction of gravity being upward. The width direction of the door panel 31 is the left-to-right direction. When a person's face is directly facing the outer surface of the cabinet door 22, the left hand is on the left and the right hand is on the right. The up-down direction is the height direction of the embedded refrigeration device 1. The left-to-right direction is the width direction of the embedded refrigeration device 1.

[0069] In order to connect each door panel 31 to its corresponding cabinet door 22, the embedded refrigeration device 1 also needs to include a fastener 4 corresponding to each door panel 31. For example, the embedded refrigeration device 1 may include a refrigerator door fastener 4 for connecting the refrigerator door 221 and the refrigerator door panel 311, and the embedded refrigeration device 1 may also include a freezer door fastener 4 for connecting the freezer door 222 and the freezer door panel 312.

[0070] Reference Figure 2 and Figure 3 The fastener 4 is generally first installed on the door panel 31 using fasteners 5, and then connected to the door 22. Fasteners 5 can be screws, bolts, etc.

[0071] Figure 3The diagram shows the structure of the two fasteners 4 on the upper left and right sides of the middle door panel 31 according to the first embodiment of the fastener 4 of this application. In this embodiment, the fastener 4 includes a door connecting part 42 and a door panel connecting part 41. The door panel connecting part 41 is plate-shaped and abuts against the rear wall of the door panel 31. The door panel connecting part 41 is provided with a connecting hole. The door panel fastener 5, i.e., a screw, passes through the connecting hole to connect the door panel connecting part 41 to the door panel 31. The door connecting part 42 is perpendicular to the door panel connecting part 41 and protrudes rearward relative to the door panel connecting part 41. The door connecting part 42 is plate-shaped and extends horizontally. The door connecting part 42 is provided with elongated holes extending left and right. The door fastener passes through the elongated holes to connect the door connecting part 42 to the box body 21, thereby realizing the connection between the box door 22 and the door panel 31. The elongated holes allow the door panel 31 to be adjusted left and right relative to the box door 22.

[0072] In this embodiment, the fasteners 4 can be symmetrically arranged, with one fastener 4 installed on the left side of the door panel 31 and the other fastener 4 installed on the right side of the door panel 31, to make the connection between the door panel 31 and the cabinet door 22 more secure. Furthermore, in this embodiment, the fasteners 4 are generally located near the upper end of the door panel 31 to achieve an adjustable connection between the upper end of the door panel 31 and the upper end of the cabinet door 22. The fasteners 4 in this embodiment can be used to connect the refrigerator door panel 311 to the refrigerator door 221, or to connect the freezer door panel 312 to the freezer door 222, and can also be used to connect other types of door panels 31 to their corresponding cabinet doors 22.

[0073] Figure 3 The four fasteners 4 on the lower side of the middle door panel 31 illustrate a structural schematic diagram of the fastener 4 according to the second embodiment of this application. In this embodiment, the fastener 4 includes a door connecting part 42 and a door panel connecting part 41. The door panel connecting part 41 is plate-shaped and abuts against the rear wall of the door panel 31. The door panel connecting part 41 is provided with a connecting hole. The door panel fastener 5, i.e., a screw, passes through the connecting hole to connect the door panel connecting part 41 to the door panel 31. The door connecting part 42 is perpendicular to the door panel connecting part 41 and protrudes rearward relative to the door panel connecting part 41. The door connecting part 42 is plate-shaped, extending vertically. The lower end of the door connecting part 42 forms a hook, and the door 22 is provided with a hook groove that engages with the hook. The hook is inserted into the hook groove from above, connecting the door connecting part 42 to the box body 21, thereby realizing the connection between the door 22 and the door panel 31.

[0074] In this embodiment, the fasteners 4 can be symmetrically arranged, with one fastener 4 installed on the left side of the door panel 31 and the other fastener 4 installed on the right side of the door panel 31, to make the connection between the door panel 31 and the cabinet door 22 more secure. Multiple pairs of fasteners 4 can be arranged vertically in this embodiment, typically two pairs: one pair symmetrically installed near the upper middle of the door panel 31, and the other pair symmetrically installed near the lower middle of the door panel 31. This arrangement makes the connection between the cabinet door 22 and the door panel 31 quick, convenient, and secure. The fasteners 4 in this embodiment can be used to connect the refrigerator door panel 311 to the refrigerator door 221, the freezer door panel 312 to the freezer door 222, and other types of door panels 31 to their corresponding cabinet doors 22.

[0075] The fastener 4 in the first embodiment and the fastener 4 in the second embodiment can be used to connect the same door panel 31 to its corresponding box door 22.

[0076] Reference Figures 4 to 22 To ensure that the door panel 31 can better cover the cabinet door 22 and avoid misalignment between the door panel 31 and the cabinet door 22, it is necessary to ensure the precise positioning of the fastener 4 on the door panel 31. Therefore, this application provides an installation fixture 6 for the door panel 31 of an embedded refrigeration device 1. The installation fixture 6 can position the fastener 4 on the door, thereby ensuring the accuracy of the fastener 4's installation position.

[0077] This application also provides a door assembly for an embedded refrigeration device 1. The door assembly may include the aforementioned door 22, door panel 31, fastener 4, and mounting fixture 6.

[0078] In the following text, the preferred embodiments of the installation tool 6 of this application will be described in detail by listing specific examples one by one.

[0079] Figures 4 to 6 The first embodiment of the mounting fixture 6 of this application is shown.

[0080] Mounting fixture 6 includes a substrate 61. The substrate 61 is used for mounting to the door panel 31. The substrate 61 includes a first side 611 and a second side 612 along its thickness direction. In use, the substrate 61 is located on the rear side of the door panel 31 and abuts against the rear sidewall of the door panel 31.

[0081] In this embodiment, the substrate 61 is generally rectangular. The substrate 61 includes four corner portions 613, namely the upper left corner portion 6131, the upper right corner portion 6132, the lower left corner portion 6133, and the lower right corner portion 6134. The substrate 61 includes four sides, namely the upper side, the lower side, the left side, and the right side.

[0082] The mounting fixture 6 includes a substrate positioning structure 62. The substrate positioning structure 62 is disposed on the substrate 61. The substrate positioning structure 62 is used to abut against the side wall of the door panel 31. The substrate positioning structure 62 is used to position the substrate 61 on the door panel 31. In other embodiments, the substrate positioning structure 62 may not be provided. For example, the substrate 61 can be positioned on the door panel 31 by aligning the edge of the substrate 61 with the edge of the door panel 31.

[0083] The substrate positioning structure 62 includes a longitudinal positioning member 621. The longitudinal positioning member 621 abuts against the upper or lower sidewall of the door panel 31 to position the substrate 61 vertically on the door panel 31. The substrate positioning structure 62 also includes a transverse positioning member 622. The transverse positioning member 622 abuts against the left or right sidewall of the door panel 31 to position the substrate 61 horizontally on the door panel 31. The longitudinal positioning member 621 may be plate-shaped. The transverse positioning member 622 may be plate-shaped.

[0084] In this embodiment, the lateral positioning member 622 and the longitudinal positioning member 621 are disposed at the corner portion 613 of the substrate 61.

[0085] The installation fixture 6 includes a fastener positioning structure 63. The fastener positioning structure 63 is used to position the fastener 4 on the door panel 31. As described above, the fastener 4 is used to connect the door panel 31 and the cabinet door 22.

[0086] The fixing positioning structure 63 of this embodiment will now be described in detail.

[0087] In this embodiment, the fixing positioning structure 63 is connected to the substrate 61 through a pre-fracture structure.

[0088] The pre-fracture structure may include several connecting ribs and openings disposed between adjacent connecting ribs. The connecting ribs are used to connect the base plate 61 and the fixing positioning structure 63. The openings between the connecting ribs are used to separate the connecting ribs, thereby facilitating the breaking of the connecting ribs and separating the fixing positioning structure 63 from the base plate 61.

[0089] In this embodiment, the fixing positioning structure 63 is integrally formed with the substrate 61. The pre-fracture structure is also integrally formed with the substrate 61. For example, the substrate 61, the substrate positioning structure 62, and the pre-fracture structure can be integrally formed by injection molding.

[0090] In this embodiment, the substrate 61 has an opening region. The fixing member positioning structure 63 includes a fixing member positioning plate 631. The fixing member positioning plate 631 is disposed in the opening region. The periphery of the fixing member positioning plate 631 is connected to the periphery of the opening region through a pre-fracture structure. The fixing member positioning plate 631 and the pre-fracture structure are integrally formed with the substrate 61.

[0091] In this embodiment, the outline of the fixing member positioning plate 631 matches the shape of the fixing member 4. At least a portion of the upper and lower edges of the fixing member positioning plate 631 are used to align with the upper and lower edges of the fixing member 4. At least a portion of the left and right edges of the fixing member positioning plate 631 are used to align with the left and right edges of the fixing member 4. By aligning the edges, the fixing member 4 can be accurately and conveniently positioned.

[0092] The substrate 61 can be flipped back and forth, meaning that both the first side 611 and the second side 612 of the substrate can be used to abut against the door panel 31. The substrate 61 can also be used in only one orientation, meaning that either the first side 611 or the second side 612 of the substrate can be used to abut against the door panel 31.

[0093] When the substrate 61 is used with only one orientation, the thickness of the fixing member positioning plate 631 can be less than, equal to, or greater than the thickness of the substrate 61. Specifically, the side of the fixing member positioning plate 631 facing the door panel 31 is coplanar with the substrate 61, so that the fixing member positioning plate 631 and the substrate 61 can simultaneously abut against the surface of the door panel 31, avoiding the positioning effect being affected by unevenness of the surface. The side of the fixing member positioning plate 631 away from the door panel 31 can be recessed inward relative to the substrate. Since the fixing member positioning plate 631 is sandwiched between the fixing member 4 and the door panel 31, this arrangement allows the fixing member positioning plate 631 to be thinner, reducing the gap between the fixing member and the door panel. Of course, the side of the fixing member positioning plate 631 away from the door panel 31 can also be coplanar with the substrate 61. In this case, the thickness of the fixing member positioning plate 631 is the same as that of the substrate 61, which can reduce the complexity of the molding die and facilitate the integral molding of the fixing member positioning plate 631 and the substrate 61. In addition, the side of the fixing plate 631 away from the door panel 31 can also protrude outward relative to the base plate 61. The thickness of the fixing plate 631 is greater than the thickness of the base plate 61, making the fixing plate 631 more robust and the positioning of the fixing member 4 more stable and reliable.

[0094] When the substrate 61 is used in two orientations, the thickness of the fixing positioning plate 631 is preferably equal to the thickness of the substrate 61. The sides of the fixing positioning plate 631 facing and away from the door panel 31 are coplanar with the substrate 61, so that when the substrate 61 is used in either orientation, the fixing positioning plate 631 and the substrate 61 can simultaneously abut against the surface of the door panel 31, avoiding the impact of uneven surfaces on the positioning effect.

[0095] When the second side 612 of the substrate is used to abut against the door panel 31, one side of the fixing member positioning plate 631 is at least coplanar with the second side 612 of the substrate to abut against the door panel 31, and the other side is used to abut against the side of the fixing member 4 facing the door panel 31 to position the fixing member 4.

[0096] When the first side 611 of the substrate is used to abut against the door panel 31, one side of the fixing member positioning plate 631 is at least coplanar with the first side 611 of the substrate to abut against the door panel 31, and the other side is used to abut against the side of the fixing member 4 facing the door panel 31 to position the fixing member 4.

[0097] In this embodiment, the substrate 61 can be flipped back and forth. One side of the fixing positioning plate 631 is coplanar with the first side 611 of the substrate, and the other side is coplanar with the second side 612 of the substrate.

[0098] In this embodiment, the fixing member positioning plate 631 is formed with a fastener clearance hole 6311, which is used for the fastener 5 to pass through to fix the fixing member 4 to the door panel 31.

[0099] The specific steps for using the installation fixture 6 in this embodiment are as follows.

[0100] Step 1: Install the substrate 61 onto the door panel 31. Specifically, install the substrate positioning structure 62 onto the substrate 61, so that the substrate 61 abuts against the rear side wall of the door panel 31, so that the lateral positioning member 622 abuts against the upper or lower side wall of the door panel 31, and the longitudinal positioning member 621 abuts against the left or right side wall of the door panel 31.

[0101] Step 2: Install the fastener 4 onto the door panel 31. Specifically, make the front side of the fastener 4 abut against the rear side of the fastener positioning plate 631, align the upper edge of the fastener 4 with the upper edge of the fastener positioning plate 631, align the lower edge of the fastener 4 with the lower edge of the fastener positioning plate 631, align the left edge of the fastener 4 with the left edge of the fastener positioning plate 631, and align the right edge of the fastener 4 with the right edge of the fastener positioning plate 631. Then, use fasteners 5 to pass through the connecting holes of the fastener 4 and the fastener clearance holes 6311 of the fastener positioning plate 631 in sequence to connect the fastener 4 to the door panel 31.

[0102] Step 3: Remove the substrate 61 and the substrate positioning structure 62. Specifically, pull the substrate 61 to detach it from the door panel 31. Since the fixing member positioning plate 631 is clamped between the fixing member 4 and the door panel 31, the fixing member positioning plate 631 does not move with the substrate 61. The pre-fracture structure between the fixing member positioning plate 631 and the substrate 61 breaks as the substrate 61 is pulled, and the fixing member positioning plate 631 separates from the substrate 61. Finally, the substrate 61 and the substrate positioning structure 62 are removed, while the fixing member positioning plate 631 remains between the fixing member 4 and the door panel 31.

[0103] In this embodiment, the fixing positioning plate 631 and the fixing member 4 used for installation are in one-to-one correspondence. When the mounting fixture 6 is used to install multiple fixing members 4, a corresponding number of fixing positioning plates 631 are provided on the base plate 61.

[0104] The base plate 61 may be provided with a left fixing member positioning plate. The left fixing member positioning plate is used to position the fixing member 4 on the left side of the door panel 31. The base plate 61 may be provided with a right fixing member positioning plate. There is a fixing member positioning plate 631 used to position the fixing member 4 on the right side of the door panel 31. The base plate 61 may be provided with an upper fixing member positioning plate. The upper fixing member positioning plate is used to position the fixing member 4 on the upper side of the door panel 31.

[0105] The substrate positioning structure 62 of this embodiment will now be described in detail.

[0106] As described above, the substrate positioning structure 62 is disposed on the substrate 61 and is used to position the substrate 61. The substrate positioning structure 62 includes a longitudinal positioning member 621 for abutting against the upper or lower side of the door panel 31. The substrate positioning structure 62 also includes a transverse positioning member 622 for abutting against the left or right side of the door panel 31.

[0107] In this embodiment, the longitudinal positioning member 621 is perpendicular to the substrate 61. The longitudinal positioning member 621 includes a first longitudinal positioning portion 6211 located on the first side 611 of the substrate. The longitudinal positioning member 621 also includes a second longitudinal positioning portion 6212 located on the second side 612 of the substrate. The lateral positioning member 622 is perpendicular to the substrate 61. The lateral positioning member 622 includes a first lateral positioning portion 6221 located on the first side 611 of the substrate. The lateral positioning member 622 also includes a second lateral positioning portion 6222 located on the second side 612 of the substrate.

[0108] With this configuration, the same substrate positioning structure 62 can have multiple usage orientations. Usage orientation refers to the position or posture of the substrate positioning structure 62 relative to the substrate 61. The posture of the substrate positioning structure 62 relative to the substrate 61 includes the first longitudinal positioning portion 6211 and the first transverse positioning portion 6221 being located on the first side 611 of the substrate, and also includes the first longitudinal positioning portion 6211 and the first transverse positioning portion 6221 being located on the second side 612 of the substrate. The position of the substrate positioning structure 62 relative to the substrate 61 includes the substrate positioning structure 62 being located at the upper left corner 6131 of the substrate 61, or at the upper right corner 6132 of the substrate 61, etc.

[0109] The substrate positioning structure 62 can be used by flipping left and right or flipping up and down. Regardless of the usage position, the lateral positioning member 622 and the longitudinal positioning member 621 of the substrate positioning structure 62 can abut against the side wall of the door panel 31, thus satisfying multiple positioning requirements with the same substrate positioning structure 62. This design is conducive to the miniaturization and compactness of the installation fixture 6, as well as improving the applicability and versatility of the installation fixture 6.

[0110] The substrate 61 includes at least two mounting positions. The substrate positioning structure 62 can be detachably coupled with each of the mounting positions. With this configuration, the same lateral positioning member 622 can be used to abut against the left or right side wall of the door panel 31, and the same longitudinal positioning member 621 can also be used to abut against the left or right side wall of the door panel 31.

[0111] In this embodiment, the substrate positioning structure 62 includes a substrate connecting plate 623. A lateral fixing plate and a longitudinal positioning member 621 are both perpendicular to the substrate connecting plate 623. The lateral positioning member 622 and the longitudinal positioning member 621 are integrally formed with the substrate connecting plate 623. The substrate connecting plate 623 is detachably connected to the substrate 61.

[0112] Specifically, the substrate connecting plate 623 is provided with a snap-fit ​​protrusion 6231, and the substrate 61 is provided with a snap-fit ​​opening 614 that mates with the snap-fit ​​protrusion 6231. The substrate connecting plate 623 and the substrate 61 are detachably connected through the engagement of the snap-fit ​​protrusion 6231 and the snap-fit ​​opening 614. Of course, other structures can also be used to achieve the detachable connection between the substrate connecting plate 623 and the substrate 61.

[0113] In this embodiment, the substrate 61 has a first number of snap-fit ​​openings 614 spaced at a predetermined distance along one side. The substrate connecting plate 623 has a second number of snap-fit ​​protrusions 6231 spaced at a predetermined distance. The first number is greater than the second number. The spacing between adjacent snap-fit ​​protrusions 6231 is the same as the spacing between adjacent snap-fit ​​openings 614. With this configuration, the mounting position of the substrate positioning structure 62 on the substrate 61 can be easily switched by simply snapping the snap-fit ​​protrusions 6231 on the substrate connecting plate 623 with different snap-fit ​​openings 614 on the substrate 61.

[0114] In this embodiment, the substrate connecting plate 623 has snap-fit ​​protrusions 6231 on both its front and rear sides that mate with the snap-fit ​​opening 614. The snap-fit ​​opening 614 extends through the substrate 61. This configuration allows the snap-fit ​​protrusions 6231 on the front side of the substrate connecting plate 623 to be snapped into the snap-fit ​​opening 614, and vice versa. This configuration ensures that the substrate connecting plate 623 can snap into the substrate 61 regardless of whether the substrate positioning structure 62 is flipped left-right or up-down, thus providing positioning for the substrate 61.

[0115] In this embodiment, the lateral positioning member 622 is disposed at the corner portion 613. The longitudinal positioning member 621 is also disposed at the corner portion 613. This arrangement makes the substrate positioning structure 62 more compact, facilitates the overall switching of the substrate positioning structure 62, and also facilitates the simultaneous vertical and horizontal positioning of the substrate 61.

[0116] The substrate 61 includes at least two mounting positions. A mounting position refers to the location or orientation of the substrate 61 relative to the door panel 31. The substrate 61 can be in different orientations relative to the door panel 31, including the first side 611 of the substrate abutting against the rear sidewall of the door panel 31, and the second side 612 of the substrate abutting against the rear sidewall of the door panel 31. The substrate 61 can be in different positions relative to the door panel 31, including near the left side of the door panel 31, or near the right side of the door panel 31, etc. In this embodiment, when the substrate 61 switches to different mounting positions, the usage orientation of the substrate positioning structure 62 also adaptively switches to adapt to the different positioning requirements of the substrate 61.

[0117] By enabling the same substrate 61 to have multiple mounting positions, the same substrate 61 can be applied to the mounting of the fasteners 4 in different areas of the same door panel 31, and even the same substrate 61 can be applied to the mounting of different door panels 31. This is beneficial for the miniaturization and compactness of the substrate 61, and improves the applicability and versatility of the substrate 61.

[0118] In this embodiment, the substrate 61 includes a first mounting position and a second mounting position. When the substrate 61 is in the first mounting position, the substrate positioning structure 62 is used to abut against the first adjacent sidewall of the door panel 31, and the fixing member positioning structure 63 is used to position a fixing member 4 on the door panel 31.

[0119] When the substrate 61 is in the second mounting position, the substrate positioning structure 62 is used to abut against the second adjacent side wall of the door panel 31, and the fixing member positioning structure 63 is used to position another fixing member 4 on the door panel 31. At least one of the second adjacent side walls is different from the first adjacent side wall.

[0120] The substrate 61 can switch between a first mounting position and a second mounting position, either for positioning the fasteners 4 in different areas of the same door panel 31, or for positioning the fasteners 4 on different door panels 31. These two scenarios will be explained in detail below.

[0121] Scenario 1 (refer to) Figure 4 or Figure 6 The same base plate 61 is used to position the fasteners 4 in different areas of the same door panel 31.

[0122] The base plate 61 is provided with a left fastener installation mark 615. The fastener positioning structure 63 includes a left fastener positioning structure 6301. The left fastener positioning structure 6301 is used to position the fastener 4 on the left side of the door panel 31. The left fastener installation mark 615 can be provided on the left fastener positioning structure 6301 or close to the left fastener positioning structure 6301 to indicate the installation position of the fastener 4 on the left side of the door panel 31.

[0123] The base plate 61 is provided with a right fastener installation mark 616. The fastener positioning structure 63 includes a right fastener positioning structure 6302. The right fastener positioning structure 6302 is used to position the fastener 4 on the right side of the door panel 31. The right fastener installation mark 616 can be provided on the right fastener positioning structure 6302 or close to the right fastener positioning structure 6302 to indicate the installation position of the fastener 4 on the right side of the door panel 31.

[0124] Because the distances between the upper and lower fixing members 4 and the side walls of the door panel 31 are different in the application, the fixing members 4 on the upper side of the door panel are farther apart from the left and right side walls of the door panel 31. In this application, the right fixing member positioning structure 6302 and the right fixing member installation mark 616 on the upper side of the door panel 31 can be set on the left side of the substrate 61, while the left fixing member positioning structure 6301 and the left fixing member installation mark 615 can be set on the right side of the substrate 61. The fixing members 4 near the lower side of the door panel are closer to the left and right side walls of the door panel 31. In this application, the right fixing member positioning structure 6302 and the right fixing member installation mark 616 near the lower side of the door panel 31 can be set on the right side of the substrate 61, while the left fixing member positioning structure 6301 and the left fixing member installation mark 616 can be set on the left side of the substrate 61.

[0125] This configuration allows both the left fixing member positioning structure 6301 and the right fixing member positioning structure 6302 to be as close as possible to the edge of the substrate 61, thereby making the left and right width of the substrate 61 much smaller than the left and right width of the door panel 31, thus achieving miniaturization of the substrate 61.

[0126] During normal use, the operator faces the exterior of the door panel 31. However, when installing the fastener 4, the operator faces the rear side wall of the door panel 31. Therefore, the orientation during installation of the fastener 4 is opposite to that during normal use of the door panel 31. The fastener 4 on the left side of the door panel 31 is actually located on the operator's right-hand side during installation; therefore, its corresponding left positioning component installation mark can be the letter "R". The fastener 4 on the right side of the door panel 31 is located on the operator's left-hand side during installation; therefore, its corresponding right positioning component installation mark can be the letter "L". This design facilitates installation and prevents incorrect installation.

[0127] In this configuration, the first mounting position of the substrate 61 refers to the substrate 61 being close to the left side of the door panel 31, and the second mounting position of the substrate 61 refers to the substrate 61 being close to the right side of the door panel 31. The door panel 31 can be a refrigerator door panel 311, a freezer door panel 312, or similar. In this configuration, the first and second mounting positions of the substrate 61 can be switched by translating the substrate 61 left and right.

[0128] When the substrate 61 is in the first mounting position, the longitudinal positioning member 621 abuts against the upper or lower side wall of the door panel 31 to align the upper or lower side of the substrate 61 with or at a predetermined distance from the upper or lower side wall of the door panel 31. The transverse positioning member 622 abuts against the left side wall of the door panel 31 to align the left side of the substrate 61 with or at a predetermined distance from the left side wall of the door panel 31. At this time, the left fixing member positioning structure 6301 is used to position the fixing member 4 on the left side of the door panel 31 to achieve the connection between the fixing member 4 on the left side of the door panel 31 and the door panel 31.

[0129] When the substrate 61 is in the second mounting position, the longitudinal positioning member 621 abuts against the upper or lower side wall of the door panel 31 to align the upper or lower side of the substrate 61 with or at a predetermined distance from the upper or lower side wall of the door panel 31. The transverse positioning member 622 abuts against the right side wall of the door panel 31 to align the right side of the substrate 61 with or at a predetermined distance from the right side wall of the door panel 31. The right fixing member positioning structure 6302 is used to position the fixing member 4 on the right side of the door panel 31 to achieve the connection between the fixing member 4 on the right side of the door panel 31 and the door panel 31.

[0130] The "preset distance" between the side of the substrate 61 and the side wall of the door panel 31 means that the side of the substrate 61 and the side wall of the door panel 31 are not aligned in a coplanar manner, but are aligned in a parallel manner with a certain distance between them, either vertically or horizontally. The specific value of the "preset distance" can be preset by the designer, such as 2cm, 3cm, etc.

[0131] To facilitate the description of changes in the mounting posture of the substrate 61, the substrate positioning structure 62 uses the corresponding changes in posture. Taking the substrate 61 in the first mounting posture as a reference, the first lateral positioning portion 6221 and the second lateral positioning portion 6222 of the lateral positioning member 622 are determined, and the first longitudinal positioning portion 6211 and the second longitudinal positioning portion 6212 of the longitudinal positioning member 621 are determined.

[0132] Specifically, in this embodiment, when the substrate 61 is in the first mounting position, the substrate positioning structure 62 is in the first use position. The substrate positioning structure 62 is mounted on the upper left corner 6131 of the substrate 61. The second longitudinal positioning part 6212 of the longitudinal positioning member 621 is used to abut against the upper side wall of the door panel 31, so that the upper side of the substrate 61 is coplanarly aligned with the upper side wall of the door panel 31. The second lateral positioning part 6222 of the lateral positioning member 622 is used to abut against the left side wall of the door panel 31, so that the left side of the substrate 61 is coplanarly aligned with the left side wall of the door panel 31.

[0133] When the substrate 61 is in the second mounting position, the substrate positioning structure 62 is in the second use position. The substrate positioning structure 62 in the second use position is rotated 180 degrees to the right relative to the substrate positioning structure 62 in the first use position. The substrate positioning structure 62 is mounted on the upper right corner 6132 of the substrate 61. The first longitudinal positioning part 6211 of the longitudinal positioning member 621 is used to abut against the upper side wall of the door panel 31, so that the upper side of the substrate 61 is coplanarly aligned with the upper side wall of the door panel 31. The first lateral positioning part 6221 of the lateral positioning member 622 is used to abut against the right side wall of the door panel 31, so that the right side of the substrate 61 is coplanarly aligned with the right side wall of the door panel 31.

[0134] Scenario 2 (refer to) Figure 4 and Figure 6 The same base plate 61 is used to position the fixing parts 4 of different door panels 31.

[0135] The base plate 61 is used to position the fasteners 4 on two different door panels 31, namely the first door panel 313 and the second door panel 314. The first door panel 313 can be a refrigerator door panel 311. The second door panel 314 can be a freezer door panel 312.

[0136] The substrate 61 is provided with a first door panel mounting mark 617. The first door panel mounting mark 617 is provided on the first side 611 of the substrate. The substrate 61 is provided with a second door panel mounting mark 618. The second door panel mounting mark 618 is provided on the second side 612 of the substrate. The door panel mounting marks are used to identify which door panel 31 the substrate 61 is being used for mounting the door panel 31 fastener 4, thereby preventing incorrect installation.

[0137] When the substrate 61 is in the first mounting position, the substrate 61 is used for mounting the fastener 4 of the first door panel 313. The second side 612 of the substrate is attached to the rear side wall of the first door panel 313. The substrate positioning structure 62 is used to abut against the adjacent side wall of the first door panel 313. The first side 611 of the substrate faces the installation worker, and the installation worker can clearly see the first door panel mounting mark 617 on the first side 611 of the substrate.

[0138] When the substrate 61 is in the second mounting position, the substrate 61 is used for mounting the fastener 4 of the second door panel 314. The first side 611 of the substrate is attached to the rear side wall of the second door panel 314, and the substrate positioning structure 62 is used to abut against the adjacent side wall of the first door panel 313. The second side 612 of the substrate faces the installation worker, and the installation worker can clearly see the second door panel mounting mark 618 on the second side 612 of the substrate.

[0139] Specifically, the first door panel installation label 617 can be an "Indicator of Installation Position for Refrigerator Door Panel Mounting". The second door panel installation label 618 can be an "Indicator of Installation Position for Freezer Door Panel Mounting". Mounting refers to fastener 4.

[0140] The fastener positioning structure 63 includes a first door panel fastener positioning structure 6303. The first door panel fastener positioning structure 6303 is used to position the fastener 4 on the first door panel 313. The fastener positioning structure 63 also includes a second door panel fastener positioning structure 6304. The second door panel fastener positioning structure 6304 is used to position the fastener 4 on the second door panel 314.

[0141] The specific configurations of the first door panel fixing member positioning structure 6303 and the second door panel fixing member positioning structure 6304 can be as described above. Specifically, the first door panel fixing member positioning structure 6303 includes a first door panel positioning plate. One side of the first door panel positioning plate is coplanar with the first side 611 of the substrate, and the other side is coplanar with the second side 612 of the substrate. The first door panel positioning plate is used to position the fixing member 4 of the first door panel 313. The second door panel fixing member positioning structure 6304 includes a second door panel positioning plate. One side of the second door panel positioning plate is coplanar with the first side 611 of the substrate, and the other side is coplanar with the second side 612 of the substrate. The second door panel positioning plate is used to position the fixing member 4 of the second door panel 314.

[0142] The first door panel fixing member positioning structure 6303 may include a left fixing member positioning structure 6301 and a right fixing member positioning structure 6302 for positioning the left and right fixing members 4 of the first door panel 313, respectively. The first side 611 of the base plate may be provided with a left fixing member installation mark 615 and a right fixing member installation mark 616 for marking the installation positions of the left and right fixing members 4 of the first door panel 313, respectively.

[0143] The second door panel fixing member positioning structure 6304 may include a left fixing member positioning structure 6301 and a right fixing member positioning structure 6302 for positioning the left and right fixing members 4 of the second door panel 314, respectively. The second side 612 of the base plate may be provided with a left fixing member installation mark 615 and a right fixing member installation mark 616 for marking the installation positions of the left and right fixing members 4 of the second door panel 314, respectively.

[0144] For ease of description, the orientation of each structure on the substrate 61 is defined with reference to the first mounting position.

[0145] When the substrate 61 is in the first mounting position, the longitudinal positioning member 621 is used to abut against the upper side wall of the first door panel 313 so that the upper side of the substrate 61 is aligned with or spaced apart from the upper side wall of the first door panel 313 by a preset distance. When the substrate positioning structure 62 is in the first use position, the transverse positioning member 622 is used to abut against the left or right side wall of the first door panel 313 so that the left or right side of the substrate 61 is aligned with or spaced apart from the left or right side wall of the first door panel 313 by a preset distance.

[0146] When the substrate 61 is in the second mounting position, the longitudinal positioning member 621 is used to abut against the upper side wall of the second door panel 314 so that the lower side of the substrate 61 is aligned with or spaced apart from the upper side wall of the second door panel 314 by a preset distance. When the substrate positioning structure 62 is in the second use position, the transverse positioning member 622 is used to abut against the left side wall or right side wall of the second door panel 314 so that the left side or right side of the second door panel 314 is aligned with or spaced apart from the left side wall or right side wall of the second door panel 314 by a preset distance.

[0147] In this case, the substrate 61 in the first mounting position can be flipped downwards by 180 degrees to obtain the substrate 61 in the second mounting position. Therefore, the substrate 61 can be switched between the first mounting position and the second mounting position by flipping the substrate 61 up and down.

[0148] Specifically, in this embodiment, when the substrate 61 is in the first mounting position, the substrate positioning structure 62 is in the first use position. The substrate positioning structure 62 is mounted on the top of the substrate 61. The longitudinal positioning member 621 abuts against the upper side wall of the first door panel 313, so that the upper side of the substrate 61 is aligned with the upper side wall of the first door panel 313. The transverse positioning member 622 abuts against the left side wall or the right side wall of the first door panel 313, so that the left side of the substrate 61 is aligned with the left side wall of the first door panel 313, or the right side of the substrate 61 is aligned with the right side wall of the first door panel 313.

[0149] When the substrate 61 is in the second mounting position, the substrate positioning structure 62 is in the second use position. The substrate positioning structure 62 is mounted on the bottom of the substrate 61. The longitudinal positioning member 621 abuts against the upper side wall of the second door panel 314, so that the lower side of the substrate 61 in the first mounting position is aligned with the upper side wall of the second door panel 314. The transverse positioning member 622 abuts against the left or right side wall of the second door panel 314, so that the left side of the substrate 61 is aligned with the left side wall of the second door panel 314, or the right side of the substrate 61 is aligned with the right side wall of the second door panel 314.

[0150] In fact, the mounting fixture 6 of this embodiment can be used in both of the above situations. It can be used for the installation of the fasteners 4 on the left and right sides of the same door panel 31, and it can also be used for the installation of the fasteners 4 on different door panels 31. The substrate 61 of this embodiment has four mounting positions. Correspondingly, the substrate positioning structure 62 has four usage positions, namely: the second side 612 of the substrate is attached to the left side of the first door panel 313, and the substrate positioning structure 62 is installed at the upper left corner 6131 of the substrate 61; the second side 612 of the substrate is attached to the right side of the first door panel 313, and the substrate positioning structure 62 is installed at the upper right corner 6132 of the substrate 61; the first side 611 of the substrate is attached to the left side of the second door panel 314, and the substrate positioning structure 62 is installed at the lower left corner 6133 of the substrate 61; the second side 612 of the substrate is attached to the right side of the second door panel 314, and the substrate positioning structure 62 is installed at the lower right corner 6134 of the substrate 61.

[0151] Figures 7 to 10 A second embodiment of the mounting fixture 6 of this application is shown.

[0152] Combination Figures 1 to 6 The main structure and function of the mounting fixture 6 in this embodiment are the same as those in the first embodiment of the mounting fixture 6 of this application, namely, it includes a substrate 61, a substrate positioning structure 62 disposed on the substrate 61 and used for positioning the substrate 61, and a fixing member positioning structure 63 disposed on the substrate 61 and used for positioning the fixing member 4. The substrate positioning structure 62 includes a longitudinal positioning member 621 and a transverse positioning member 622, etc.

[0153] The main difference between this embodiment and the first embodiment lies in the specific structures of the substrate positioning structure 62 and the fixing member positioning structure 63. The substrate positioning structure 62 of this embodiment will be described in detail below.

[0154] In this embodiment, the longitudinal positioning member 621 is movably connected to the substrate 61 and can switch between a state coplanar with the substrate 61 and a state perpendicular to it. The transverse positioning member 622 is movably connected to the substrate 61 and can switch between a state coplanar with the substrate 61 and a state perpendicular to it. When positioning using the substrate positioning structure 62 is required, the longitudinal positioning member 621 and the transverse positioning member 622 can be adjusted to a state perpendicular to the substrate 61, so that the longitudinal positioning member 621 and the transverse positioning member 622 can abut against the side wall of the door panel 31. When positioning using the substrate positioning structure 62 is not required, the longitudinal positioning member 621 and the transverse positioning member 622 can be adjusted to a state coplanar with the substrate 61, reducing interference and facilitating the placement and removal of the substrate 61.

[0155] In this embodiment, both the longitudinal positioning member 621 and the transverse positioning member 622 are rotatably connected to the substrate 61 via a thin-film hinge structure. The longitudinal positioning member 621 and the transverse positioning member 622 are integrally formed with the substrate 61. In other embodiments, the longitudinal positioning member 621 and the transverse positioning member 622 may also be movably connected to the substrate 61 via other structures.

[0156] The longitudinal positioning member 621 is provided with a first connecting structure 6213. The transverse positioning member 622 is provided with a second connecting structure 6223. The first connecting structure 6213 and the second connecting structure 6223 are connected to fix the longitudinal positioning member 621 and the transverse positioning member 622 in a state perpendicular to the substrate 61. The first connecting structure 6213 can be a snap-fit ​​62131, and the second connecting structure 6223 can be a slot 62231 that mates with the snap-fit ​​62131.

[0157] When the substrate positioning structure 62 is required for positioning, the longitudinal positioning member 621 and the transverse positioning member 622 can be adjusted to be perpendicular to the substrate 61. Then, the longitudinal positioning member 621 and the transverse positioning member 622 are snapped together, thereby constraining each other and keeping them perpendicular to the substrate 61, which facilitates the positioning of the substrate 61.

[0158] In this embodiment, the substrate positioning structure 62 includes a left lateral positioning member 6224 and a left longitudinal positioning member 6214 disposed at the upper left corner 6131 of the substrate 61. The left longitudinal positioning member 6214 has a latch 62131 at its left end, and the upper end of the left lateral positioning member 6224 has a groove 62231 that engages with the latch 62131. The substrate positioning structure 62 also includes a right lateral positioning member 6225 and a right longitudinal positioning member 6215 disposed at the upper right corner 6132 of the substrate 61. The right end of the right longitudinal positioning member 6215 has a latch 62131, and the upper end of the right lateral positioning member 6225 has a groove 62231 that engages with the latch 62131.

[0159] The fixing positioning structure 63 of this embodiment will now be described in detail.

[0160] The substrate 61 includes a first side 611 and a second side 612 along its thickness direction. The second side 612 is used to abut against the door panel 31. In this embodiment, only one side of the substrate 61 is used to abut against the door panel 31, instead of the first embodiment where both the front and rear sides of the substrate 61 can abut against the door panel 31.

[0161] In this embodiment, the fastener positioning structure 63 includes a positioning groove 632. The positioning groove 632 is disposed on the substrate 61. The positioning groove 632 has a contour that matches the shape of the fastener 4. The positioning groove 632 has a first mounting opening 6321. The first mounting opening 6321 communicates the positioning groove 632 with the second side 612 of the substrate, so that the fastener 4 can be inserted into or disengaged from the second side 612 of the substrate. The fastener positioning structure 63 includes a positioning protrusion 633. The positioning protrusion 633 is disposed on the circumferential inner wall of the positioning groove 632 and is used for interference fit with the fastener 4.

[0162] In this embodiment, the positioning groove 632 also has a limiting wall 6320 spaced apart from the first assembly opening 6321. The limiting wall 6320 is used to prevent the fixing member 4 inserted into the positioning groove 632 from dislodging from the first side 611 of the substrate.

[0163] In this embodiment, the limiting wall 6320 is provided with a fastener clearance hole 6311, which is used to allow the fastener 5 of the fixing member 4 to pass completely through. The diameter of the fastener clearance hole 6311 is larger than the maximum outer diameter of the fastener 5.

[0164] In this embodiment, the limiting wall 6320 has a profile that matches the side surface of the fastener 4 facing away from the door panel 31. The limiting wall 6320 is provided with a clearance opening 6323. The clearance opening 6323 is for the door connecting portion 42 of the fastener 4 to pass through. The fastener positioning structure 63 is integrally formed with the base plate 61.

[0165] In this embodiment, the positioning protrusion 633 includes a plurality of spaced-apart upper positioning protrusions. The upper positioning protrusions are disposed on the upper wall of the positioning groove 632. The positioning protrusion 633 also includes a plurality of spaced-apart lower positioning protrusions. The lower positioning protrusions are disposed on the lower wall of the positioning groove 632 and are at least partially opposite to the upper positioning protrusions. The positioning protrusion 633 also includes a plurality of spaced-apart left positioning protrusions, which are disposed on the left wall of the positioning groove 632. The positioning protrusion 633 further includes a plurality of spaced-apart right positioning protrusions, which are disposed on the right wall of the positioning groove 632 and are at least partially opposite to the left positioning protrusions.

[0166] The specific steps for using the installation fixture 6 in this embodiment are as follows.

[0167] Step 1: Install the fastener 4 onto the base plate 61. Specifically, insert the fastener 4 into the positioning groove 632 from the second side 612 of the base plate. The door panel connecting part 41 of the fastener 4 is inserted into the positioning groove 632. The door connecting part 42 of the fastener 4 protrudes from the clearance opening 6323 through the positioning groove 632. The limiting part and the positioning protrusions 633 in all four directions above and below limit the door panel connecting part 41 of the fastener 4 to ensure the accuracy of the installation position of the fastener 4 and prevent the fastener 4 from falling off the base plate 61.

[0168] Step 2: Install the substrate 61 onto the door panel 31. Specifically, place the second side 612 of the substrate against the rear side wall of the door panel 31, and the fixing member 4 will then be placed against the rear side wall of the door panel 31. Adjust the lateral positioning member 622 and the longitudinal positioning member 621 to be perpendicular to the substrate 61 and then engage them with each other, so that the lateral positioning member 622 abuts against the upper or lower side wall of the door panel 31, and the longitudinal positioning member 621 abuts against the left or right side wall of the door panel 31.

[0169] Step 3: Install the fastener 4 onto the door panel 31. Specifically, use the fastener 5 to pass through the fastener clearance hole 6311 of the limiting plate and the connection hole of the fastener 4 in sequence to fix the fastener 4 onto the door panel 31.

[0170] Step 4: Remove the substrate 61 and the substrate positioning structure 62. Specifically, pull the substrate 61 to detach it from the door panel 31. The substrate positioning structure 62 moves with the substrate 61, and the fastener 4 detaches from the second side 612 of the substrate. Finally, the substrate 61 and the substrate positioning structure 62 are removed, while the fastener 4 and its fasteners 5 remain on the door panel 31.

[0171] In this embodiment, the positioning grooves 632 and the fasteners 4 used for installation are in one-to-one correspondence. When the mounting fixture 6 is used to install multiple fasteners 4, a plurality of positioning grooves 632 are provided on the base plate 61 accordingly.

[0172] In this embodiment, the positioning groove 632 includes an upper positioning groove. The upper positioning groove has a contour that matches the shape of the fastener 4 on the upper side of the door panel 31 to position the fastener 4 on the upper side of the door panel 31. The positioning groove 632 also includes a lower positioning groove, which has a contour that matches the shape of the fastener 4 on the lower side of the door panel 31 to position the fastener 4 on the lower side of the door panel 31. The positioning groove 632 includes an upper left positioning groove, which has a contour that matches the shape of the fastener 4 on the left side of the door panel 31 to position the fastener 4 on the left side of the door panel 31. The positioning groove 632 also includes an upper right positioning groove, which has a contour that matches the shape of the fastener 4 on the right side of the door panel 31 to position the fastener 4 on the right side of the door panel 31.

[0173] The substrate 61 of this embodiment includes a first mounting position and a second mounting position as described in the first embodiment for positioning the fasteners 4 on the left and right sides of the same door panel 31. The substrate 61 is provided with a left fastener mounting mark 615. The fastener positioning structure 63 includes a left fastener positioning structure 6301. The left fastener positioning structure 6301 is used to position the fastener 4 on the left side of the door panel 31. The left fastener mounting mark 615 can be provided on the left fastener positioning structure 6301 or close to it to indicate the installation position of the fastener 4 on the left side of the door panel 31. The substrate 61 is provided with a right fastener mounting mark 616. The fastener positioning structure 63 includes a right fastener positioning structure 6302. The right fastener positioning structure 6302 is used to position the fastener 4 on the right side of the door panel 31. The right fastener installation mark 616 can be set on the right fastener positioning structure 6302 or near the right fastener positioning structure 6302 to indicate the installation position of the fastener 4 on the right side of the door panel 31.

[0174] In this embodiment, when the substrate 61 is in the first mounting position, the left lateral positioning member 6224 and the left longitudinal positioning member 6214 located at the upper left corner 6131 of the substrate 61 are adjusted to be perpendicular to the substrate 61 and are engaged with each other. The left longitudinal positioning member 6214 is used to abut against the upper side wall of the door panel 31 so that the upper side of the substrate 61 is coplanarly aligned with the upper side wall of the door panel 31. The left lateral positioning member 6224 is used to abut against the left side wall of the door panel 31 so that the left side of the substrate 61 is coplanarly aligned with the left side wall of the door panel 31.

[0175] When the substrate 61 is in the second mounting position, the right lateral positioning member 6225 and the right longitudinal positioning member 6215 located at the upper right corner 6132 of the substrate 61 are adjusted to be perpendicular to the substrate 61 and are engaged with each other. The right longitudinal positioning member 6215 is used to abut against the upper side wall of the door panel 31 so that the upper side of the substrate 61 is coplanarly aligned with the upper side wall of the door panel 31. The right lateral positioning member 6225 is used to abut against the right side wall of the door panel 31 so that the right side of the substrate 61 is coplanarly aligned with the right side wall of the door panel 31.

[0176] In this embodiment, the mounting fixture 6 further includes a fastener pre-storage structure 64, which is disposed on the substrate 61 and uses fasteners 5 for storing and fixing the fixing member 4. The fastener pre-storage structure 64 is integrally formed with the substrate 61.

[0177] Figure 11 and Figure 12 The third embodiment of the mounting fixture 6 of this application is shown.

[0178] Combination Figures 1 to 10 The main structure and function of the installation fixture 6 in this embodiment are the same as those in the first and second embodiments, namely, it includes a substrate 61, a substrate positioning structure 62 disposed on the substrate 61 and used for positioning the substrate 61, and a fastener positioning structure 63 disposed on the substrate 61 and used for positioning the fastener 4.

[0179] Combination Figures 7 to 10 The fixing member positioning structure 63 in this embodiment is the same as the fixing member positioning structure 63 in the second embodiment, that is, the second side 612 of the substrate is used to abut against the door panel 31. The fixing member positioning structure 63 includes a positioning groove 632 provided on the substrate 61. The positioning groove 632 has a first assembly opening 6321 that connects the positioning groove 632 with the second side 612 of the substrate. The positioning groove 632 has a positioning protrusion 633 on its circumferential inner wall. The positioning groove 632 also has a limiting wall 6320 that is spaced apart from the first assembly opening 6321. The limiting wall 6320 has a fastener clearance hole 6311. The fixing member positioning structure 63 includes a left fixing member positioning structure 6301 and a right fixing member positioning structure 6302, etc.

[0180] The substrate 61 in this embodiment also includes a first mounting position and a second mounting position as described in the previous two embodiments for positioning the fixing members 4 on the left and right sides of the same door panel 31.

[0181] The base plate 61 is provided with a left fastener installation mark 615. The fastener positioning structure 63 includes a left fastener positioning structure 6301. The left fastener positioning structure 6301 is used to position the fastener 4 on the left side of the door panel 31. The left fastener installation mark 615 can be provided on the left fastener positioning structure 6301 or close to the left fastener positioning structure 6301 to indicate the installation position of the fastener 4 on the left side of the door panel 31.

[0182] The base plate 61 is provided with a right fastener installation mark 616. The fastener positioning structure 63 includes a right fastener positioning structure 6302. The right fastener positioning structure 6302 is used to position the fastener 4 on the right side of the door panel 31. The right fastener installation mark 616 can be provided on the right fastener positioning structure 6302 or close to the right fastener positioning structure 6302 to indicate the installation position of the fastener 4 on the right side of the door panel 31.

[0183] The main difference between this embodiment and the previous two embodiments lies in the substrate positioning structure 62. The substrate positioning structure 62 of this embodiment will be described in detail below.

[0184] In this embodiment, the substrate positioning structure 62 includes a substrate positioning member 620, which abuts against the side of the door panel 31. The substrate positioning member 620 may be plate-shaped. An adjustable connection structure is provided between the substrate positioning structure 62 and the substrate 61, which is used to adjust the relative position of the substrate positioning member 620 and the substrate 61.

[0185] By setting the relative position of the substrate positioning member 620 and the substrate 61 to be adjustable, the installation fixture 6 can be applied more flexibly and widely. It can be used to position the same substrate 61 on different door panels 31, or to position the same substrate 61 in different areas of the same door panel 31.

[0186] In this embodiment, the substrate positioning structure 62 may include a substrate connecting plate 623. The substrate 61 may be provided with a substrate positioning groove 619. The substrate positioning groove 619 is slidably engaged with the substrate connecting plate 623. The adjustable connection structure between the substrate positioning structure 62 and the substrate 61 refers to the engagement structure between the substrate connecting plate 623 and the substrate positioning groove 619.

[0187] In this embodiment, the substrate connecting plate 623 may be provided with a scale 6232, and the substrate positioning groove 619 may be provided with a scale opening 6191. The scale opening 6191 can be used to expose at least a portion of the scale 6232. A triangular indicator block 6192 may be provided on the sidewall of the scale opening 6191, and the tip of the triangular indicator block 6192 is used to accurately indicate the scale 6232. This arrangement facilitates precise adjustment of the relative position between the substrate positioning member 620 and the substrate 61.

[0188] In this embodiment, the substrate positioning member 620 includes a longitudinal positioning member 621. The longitudinal positioning member 621 is used to abut against the upper side and / or lower side of the door panel 31. The substrate positioning member 620 also includes a transverse positioning member 622. The transverse positioning member 622 is used to abut against the left side and / or right side of the door panel 31.

[0189] The substrate connecting plate 623 includes a vertical substrate connecting plate 6233. The vertical substrate connecting plate 6233 is fixedly connected to the vertical positioning member 621. The vertical positioning member 621 is perpendicular to the vertical substrate connecting plate 6233. The substrate positioning member 620 includes a horizontal substrate connecting plate 6234. The horizontal substrate connecting plate 6234 is fixedly connected to the horizontal positioning member 622. The horizontal positioning member 622 is perpendicular to the horizontal substrate connecting plate 6234.

[0190] The substrate positioning slide 619 includes a vertical substrate positioning slide 6195. The vertical substrate positioning slide 6195 cooperates with a vertical substrate connecting plate 6233, allowing the vertical substrate connecting plate 6233 to slide vertically. The substrate positioning slide 619 also includes a horizontal substrate positioning slide 6196. The horizontal substrate positioning slide 6196 cooperates with a horizontal substrate connecting plate 6234, allowing the horizontal substrate connecting plate 6234 to slide horizontally. This configuration allows for adjustment of both the vertical and horizontal positioning of the substrate 61.

[0191] In this embodiment, the lateral positioning member 622 may further include a left lateral positioning member 6224. The left lateral positioning member 6224 is used to abut against the left side of the door panel 31. The lateral positioning member 622 may further include a right lateral positioning member. The right lateral positioning member is used to abut against the right side of the door panel 31.

[0192] Correspondingly, the horizontal substrate connecting plate 6234 may include a left substrate connecting plate, which is fixedly connected to the left horizontal positioning member 6224. The horizontal substrate connecting plate 6234 may include a right substrate connecting plate, which is fixedly connected to the right positioning plate. The horizontal substrate positioning groove 6196 may include a left substrate positioning groove, which cooperates with the left substrate connecting plate. The horizontal substrate positioning groove 6196 may also include a right substrate positioning groove, which cooperates with the right substrate connecting plate. With this configuration, the substrate 61 can be positioned when it is against the left side of the door panel 31, and it can also be positioned when it is against the right side of the door panel 31.

[0193] In this embodiment, the substrate 61 has a first side 611 and a second side 612 along its thickness direction. The second side 612 is used to abut against the door panel 31. One side of the substrate positioning groove 619 is coplanar with the second side 612, and the other side protrudes from the first side 611.

[0194] In this embodiment, the substrate positioning groove 619 has a first end 6193 and a second end 6194 opposite to each other along the sliding direction of the substrate connecting plate 623. The first end 6193 is provided with a first opening, and the second end 6194 is provided with a second opening. Both the first opening and the second opening allow the substrate connecting plate 623 to pass through. With this configuration, even when the length of the substrate positioning groove 619 is less than the length of the substrate connecting plate 623, the substrate connecting plate 623 can still be guided, preventing interference with the sliding of the substrate connecting plate 623.

[0195] In this embodiment, when the vertical substrate positioning groove 6195 is disposed on the upper part of the substrate 61, the upper end of the vertical substrate positioning groove 6195 is flush with the upper end of the substrate 61. When the vertical substrate positioning groove 6195 is disposed on the lower part of the substrate 61, the lower end of the vertical substrate positioning groove 6195 is flush with the lower end of the substrate 61. When the vertical substrate positioning groove 6195 is disposed on the left side of the substrate 61, the left end of the vertical substrate positioning groove 6195 is flush with the left end of the substrate 61. When the vertical substrate positioning groove 6195 is disposed on the right side of the substrate 61, the right end of the vertical substrate positioning groove 6195 is flush with the right end of the substrate 61.

[0196] Figure 13 and Figure 14 The fourth embodiment of the mounting fixture 6 of this application is shown.

[0197] Combination Figures 1 to 12The main structure and function of the installation fixture 6 in this embodiment are the same as those in the previous three embodiments, namely, it includes a substrate 61, a substrate positioning structure 62 disposed on the substrate 61 and used for positioning the substrate 61, and a fixing member positioning structure 63 disposed on the substrate 61 and used for positioning the fixing member 4. The substrate positioning structure 62 includes a longitudinal positioning member 621 and a transverse positioning member 622, etc.

[0198] Similar to the second and third embodiments, in this embodiment, the substrate 61 includes a first side 611 and a second side 612 along its thickness direction. The second side 612 can be used to abut against the door panel 31. The fixing member positioning structure 63 includes a positioning groove 632. The positioning groove 632 is disposed on the substrate 61. The positioning groove 632 has a contour that matches the shape of the fixing member 4. The positioning groove 632 has a first mounting opening 6321. The first mounting opening 6321 communicates the positioning groove 632 with the second side 612 of the substrate, so that the fixing member 4 can be inserted into or disengaged from the second side 612 of the substrate. The fixing member positioning structure 63 includes a positioning protrusion 633. The positioning protrusion 633 is disposed on the circumferential inner wall of the positioning groove 632 and is used for interference fit with the fixing member 4.

[0199] The difference from the second embodiment is that the positioning groove 632 in this embodiment has a second assembly opening 6322. The second assembly opening 6322 connects the positioning groove 632 to the first side 611 of the substrate, allowing the fixing member 4 to be inserted into or detached from the positioning groove 632 from the first side 611 of the substrate. In other words, the positioning groove 632 in this embodiment does not have the limiting wall 6320 described in the second and third embodiments; both sides of the positioning groove 632 are open, so that the positioning groove 632 communicates not only with the first side 611 of the substrate but also with the second side 612 of the substrate. This arrangement allows the fixing member 4 to be inserted into or detached from the positioning groove 632 from both the first side 611 and the second side 612 of the substrate, resulting in a simpler structure and easier assembly and disassembly of the fixing member 4.

[0200] In this embodiment, the first side 611 of the substrate can also be used to abut against the door panel 31. That is, the substrate 61 can be flipped back and forth as described in Embodiment 1. In this case, the front and rear sides of the positioning groove 632 need to be coplanar with the front and rear sides of the substrate 61 to prevent interference between the substrate 61 and the door panel 31.

[0201] In other embodiments, only the second side 612 of the substrate may be used to abut against the door panel 31, with the edge of the second mounting opening 6322 at least partially protruding from the second side 612 of the substrate. This arrangement increases the depth of the positioning groove 632, enhancing the positioning effect on the fastener 4.

[0202] In this embodiment, the substrate 61 includes a first mounting position and a second mounting position. Unlike the previous three embodiments, the mounting position of the substrate 61 in this embodiment is switched by left-right flipping and left-right translation. Furthermore, the fixing members 4 symmetrically arranged on the left and right sides of the door panel 31 can be positioned by the same fixing member positioning structure 63 on the substrate 61. The structure on the substrate 61 is thus simplified. The first and second mounting positions of the substrate 61 and related structural settings of this embodiment will be discussed in detail below.

[0203] In this embodiment, the fixing member positioning structure 63 includes left and right member positioning structures 634 disposed in a region of the base plate 61. The left and right member positioning structures 634 can be used to position the fixing members 4 on the left and right sides of the door panel 31.

[0204] The substrate 61 is provided with a left fastener mounting mark 615. The left fastener mounting mark 615 is provided on the first side 611 of the substrate. The left fastener mounting mark 615 can be provided on the left and right part positioning structure 634, or it can be provided close to the left and right part positioning structure 634, so as to indicate the mounting position of the fastener 4 on the left side of the door panel 31.

[0205] The substrate 61 is provided with a right fastener mounting mark 616. The right fastener mounting mark 616 is provided on the second side 612 of the substrate. The right fastener mounting mark 616 can be provided on the left and right part positioning structure 634, or it can be provided close to the left and right part positioning structure 634, so as to indicate the mounting position of the fastener 4 on the right side of the door panel 31.

[0206] When the substrate 61 is in the first mounting position, the longitudinal positioning member 621 is used to abut against the upper or lower side wall of the door panel 31 so that the upper or lower side of the substrate 61 is aligned with or spaced apart from the upper or lower side wall of the door panel 31 by a preset distance. The transverse positioning member 622 is used to abut against the left side wall of the door panel 31 so that the left side of the substrate 61 is aligned with or spaced apart from the left side wall of the door panel 31 by a preset distance. The left and right positioning structure 634 is used to position the fixing member 4 on the left side of the door panel 31.

[0207] The longitudinal positioning member 621 is used to abut against the upper or lower side wall of the door panel 31 so that the upper or lower side of the substrate 61 is aligned with the upper or lower side wall of the door panel 31. The transverse positioning member 622 is used to abut against the right side wall of the door panel 31 so that the left side of the substrate 61 is aligned with the right side wall of the door panel 31 or at a preset distance. The left and right positioning structures are used to position the fixing member 4 on the right side of the door panel 31.

[0208] In this embodiment, the longitudinal positioning member 621 is perpendicular to the substrate 61. The longitudinal positioning member 621 includes a first longitudinal positioning portion 6211 located on the first side 611 of the substrate. The longitudinal positioning member 621 also includes a second longitudinal positioning portion 6212 located on the second side 612 of the substrate. The lateral positioning member 622 is perpendicular to the substrate 61. The lateral positioning member 622 includes a first lateral positioning portion 6221 located on the first side 611 of the substrate. The lateral positioning member 622 also includes a second lateral positioning portion 6222 located on the second side 612 of the substrate. The substrate positioning structure 62 is fixedly disposed at the corner portion 613 of the substrate 61.

[0209] In this embodiment, when the substrate 61 is in the first mounting position, the second side 612 of the substrate is attached to the door panel 31, the substrate positioning structure 62 is located at the upper left corner 6131 of the substrate 61, the second longitudinal positioning part 6212 abuts against the upper side wall of the door panel 31 so that the upper side of the substrate 61 is flush with the upper side wall of the door panel 31, the second transverse positioning part 6222 abuts against the left side wall of the door panel 31 so that the left side of the substrate 61 is flush with the left side wall of the door panel 31, and the positioning groove 632 is used to position the fixing member 4 on the left side of the door panel 31.

[0210] When the substrate 61 is in the second mounting position, the first side 611 of the substrate is against the door panel 31, the first longitudinal positioning part 6211 abuts against the upper side wall of the door panel 31 so that the upper side of the substrate 61 is flush with the upper side wall of the door panel 31, the first transverse positioning part 6221 abuts against the right side wall of the door panel 31 so that the left side of the substrate 61 is flush with the right side wall of the door panel 31, and the positioning groove 632 is used to position the fixing member 4 on the right side of the door panel 31.

[0211] Figure 15 and Figure 16 The fifth embodiment of the mounting fixture 6 of this application is shown.

[0212] Combination Figure 13 and Figure 14 This embodiment is basically the same in structure as the fourth embodiment, except that the longitudinal positioning member 621 and the transverse positioning member 622 are provided separately and are not provided at the corner 613 of the substrate 61. In this embodiment, the longitudinal positioning member 621 can be provided in the middle of the left or right side of the substrate 61, and the transverse positioning member 622 can be provided in the middle of the upper or lower side of the substrate 61.

[0213] Specifically, in this embodiment, the longitudinal positioning member 621 is perpendicular to the substrate 61. The longitudinal positioning member 621 includes a first longitudinal positioning portion 6211 located on the first side 611 of the substrate and a second longitudinal positioning portion 6212 located on the second side 612 of the substrate. The lateral positioning member 622 is perpendicular to the substrate 61. The lateral positioning member 622 includes a first lateral positioning portion 6221 located on the first side 611 of the substrate and a second lateral positioning portion 6222 located on the second side 612 of the substrate.

[0214] In this embodiment, the substrate 61 includes a first mounting position and a second mounting position. The mounting position of the substrate 61 can be switched by flipping left and right and translating left and right. Moreover, the fixing members 4 symmetrically arranged on the left and right sides of the door panel 31 can be positioned by the same fixing member positioning structure 63 on the substrate 61.

[0215] In this embodiment, the fixing member positioning structure 63 includes left and right member positioning structures 634 disposed in a region of the base plate 61. The left and right member positioning structures 634 can be used to position the fixing members 4 on the left and right sides of the door panel 31.

[0216] The substrate 61 is provided with a left fastener mounting mark 615. The left fastener mounting mark 615 is provided on the first side 611 of the substrate. The left fastener mounting mark 615 can be provided close to the left and right component positioning structure 634 to indicate the mounting position of the fastener 4 on the left side of the door panel 31. The substrate 61 is provided with a right fastener mounting mark 616. The right fastener mounting mark 616 is provided on the second side 612 of the substrate. The right fastener mounting mark 616 can be provided close to the left and right component positioning structure 634 to indicate the mounting position of the fastener 4 on the right side of the door panel 31.

[0217] In this embodiment, the left and right component positioning structure 634 includes a positioning groove 632. The positioning groove 632 is disposed on the substrate 61. The positioning groove 632 has a contour that matches the shape of the fixing member 4. The positioning groove 632 has a first mounting opening 6321. The first mounting opening 6321 communicates the positioning groove 632 with the second side 612 of the substrate, so that the fixing member 4 can be inserted into or disengaged from the second side 612 of the substrate. The left and right component positioning structure 634 includes a positioning protrusion 633. The positioning protrusion 633 is disposed on the circumferential inner wall of the positioning groove 632 and is used for interference fit with the fixing member 4.

[0218] The positioning groove 632 in this embodiment has a second assembly opening 6322. The second assembly opening 6322 communicates the positioning groove 632 with the first side 611 of the substrate, so that the fixing member 4 can be inserted into or detached from the positioning groove 632 from the first side 611 of the substrate. That is, the positioning groove 632 in this embodiment does not have the limiting wall 6320 described in the second embodiment, and both sides of the positioning groove 632 are open, so that the positioning groove 632 communicates not only with the first side 611 of the substrate, but also with the second side 612 of the substrate.

[0219] The front and rear sides of the positioning groove 632 are coplanar with the front and rear sides of the substrate 61 to prevent interference between the substrate 61 and the door panel 31.

[0220] When the substrate 61 is in the first mounting position, the second longitudinal positioning part 6212 is used to abut against the upper side wall of the door panel 31 so that the upper side of the substrate 61 is aligned with the upper side wall of the door panel 31, the second transverse positioning part 6222 is used to abut against the left side wall of the door panel 31 so that the left side of the substrate 61 is aligned with the left side wall of the door panel 31, and the left and right part positioning structure 634 is used to position the fixing part 4 on the left side of the door panel 31.

[0221] When the substrate 61 is in the second mounting position, the first longitudinal positioning part 6211 is used to abut against the upper side wall of the door panel 31 so that the upper side of the substrate 61 is aligned with the upper side wall of the door panel 31, the first transverse positioning part 6221 is used to abut against the right side wall of the door panel 31 so that the left side of the substrate 61 is aligned with the right side wall of the door panel 31, and the left and right part positioning structure 634 is used to position the fixing part 4 on the right side of the door panel 31.

[0222] Figure 17 The sixth embodiment of the mounting fixture 6 of this application is shown.

[0223] Combination Figures 7 to 10 The substrate positioning structure 62 in this embodiment is the same as in the second embodiment. Specifically, in this embodiment, the longitudinal positioning member 621 is movably connected to the substrate 61 and can switch between a coplanar state with the substrate 61 and a perpendicular state. The transverse positioning member 622 is movably connected to the substrate 61 and can switch between a coplanar state with the substrate 61 and a perpendicular state. Both the longitudinal positioning member 621 and the transverse positioning member 622 are rotatably connected to the substrate 61 via a thin-film hinge structure. The longitudinal positioning member 621 and the transverse positioning member 622 are integrally formed with the substrate 61.

[0224] The longitudinal positioning member 621 is provided with a first connecting structure 6213. The transverse positioning member 622 is provided with a second connecting structure 6223. The first connecting structure 6213 and the second connecting structure 6223 are connected to fix the longitudinal positioning member 621 and the transverse positioning member 622 in a state perpendicular to the substrate 61. The first connecting structure 6213 can be a snap-fit ​​62131, and the second connecting structure 6223 can be a slot 62231 that mates with the snap-fit ​​62131.

[0225] The substrate positioning structure 62 includes a left lateral positioning member 6224 and a left longitudinal positioning member 6214 disposed at the upper left corner 6131 of the substrate 61. A latch 62131 is provided at the left end of the left longitudinal positioning member 6214, and a slot 62231 that engages with the latch 62131 is provided at the upper end of the left lateral positioning member 6224. The substrate positioning structure 62 also includes a right lateral positioning member 6225 and a right longitudinal positioning member 6215 disposed at the upper right corner 6132 of the substrate 61. A latch 62131 is provided at the right end of the right longitudinal positioning member 6215, and a slot 62231 that engages with the latch 62131 is provided at the upper end of the right lateral positioning member 6225.

[0226] Combination Figures 13 to 14 The fixing member positioning structure 63 in this embodiment is basically the same as that in the fourth embodiment. Specifically, the fixing member 4 structure in this embodiment includes a positioning groove 632 and a positioning protrusion 633 disposed on the circumferential inner wall of the positioning groove 632. One side of the positioning groove 632 has a first assembly opening 6321 communicating with the second side 612 of the substrate, and the other side has a first assembly opening 6321 communicating with the first side 611 of the substrate. The difference is that the edge of the second assembly opening 6322 in this embodiment at least partially protrudes from the first side 611 of the substrate. The left and right edges of the second assembly opening 6322 can protrude outward relative to the first side 611 of the substrate, forming left and right protruding edges. The upper and lower edges of the second assembly opening 6322 can protrude outward relative to the first side 611 of the substrate, forming upper and lower protruding edges. This arrangement can increase the depth of the positioning groove 632, making the positioning more stable and reliable, and the effect better, so that the fixing member 4 is not easy to loosen or fall out of the positioning groove 632 after being inserted into the positioning groove 632.

[0227] The arrangement of the fixing member positioning structure 63 in this embodiment is the same as in the second embodiment. Specifically, the fixing member positioning structure 63 includes a left fixing member positioning structure 6301 disposed on the left side of the substrate 61 and a right fixing member positioning structure 6302 disposed on the right side of the substrate 61.

[0228] Combination Figures 4 to 12The substrate 61 in this embodiment also includes a first mounting position and a second mounting position as described in the first to third embodiments for positioning the fixing members 4 on the left and right sides of the same door panel 31, and the switching between the first mounting position and the second mounting position is achieved by translating the substrate 61 left and right.

[0229] Specifically, when the substrate 61 is in the first mounting position, the left lateral positioning member 6224 and the left longitudinal positioning member 6214 located at the upper left corner 6131 of the substrate 61 are adjusted to be perpendicular to the substrate 61 and are engaged with each other. The left longitudinal positioning member 6214 is used to abut against the upper side wall of the door panel 31 so that the upper side of the substrate 61 is coplanarly aligned with the upper side wall of the door panel 31. The left lateral positioning member 6224 is used to abut against the left side wall of the door panel 31 so that the left side of the substrate 61 is coplanarly aligned with the left side wall of the door panel 31.

[0230] When the substrate 61 is in the second mounting position, the right lateral positioning member 6225 and the right longitudinal positioning member 6215 located at the upper right corner 6132 of the substrate 61 are adjusted to be perpendicular to the substrate 61 and are engaged with each other. The right longitudinal positioning member 6215 is used to abut against the upper side wall of the door panel 31 so that the upper side of the substrate 61 is coplanarly aligned with the upper side wall of the door panel 31. The right lateral positioning member 6225 is used to abut against the right side wall of the door panel 31 so that the right side of the substrate 61 is coplanarly aligned with the right side wall of the door panel 31.

[0231] In this embodiment, the mounting fixture 6 further includes a fastener pre-storage structure 64, which is disposed on the substrate 61 and uses fasteners 5 for storing and fixing the fixing member 4. The fastener pre-storage structure 64 is integrally formed with the substrate 61.

[0232] Figures 18 to 20 The seventh embodiment of the mounting fixture 6 of this application is shown.

[0233] Combination Figure 4 and Figure 6 The substrate positioning structure 62 in this embodiment is basically the same as that in the first embodiment. Specifically, the substrate positioning structure 62 includes a longitudinal positioning member 621 for abutting against the upper side of the door panel 31. The substrate positioning structure 62 also includes a transverse positioning member 622 for abutting against the left or right side of the door panel 31. The longitudinal positioning member 621 is perpendicular to the substrate 61. The longitudinal positioning member 621 includes a first longitudinal positioning portion 6211 located on the first side 611 of the substrate and a second longitudinal positioning portion 6212 located on the second side 612 of the substrate. The transverse positioning member 622 is perpendicular to the substrate 61. The transverse positioning member 622 includes a first transverse positioning portion 6221 located on the first side 611 of the substrate and a second transverse positioning portion 6222 located on the second side 612 of the substrate.

[0234] The substrate positioning structure 62 can be flipped left and right for use. The substrate 61 includes two mounting positions, and the substrate positioning structure 62 can be detachably coupled to each mounting position. The substrate positioning structure 62 includes a substrate connecting plate 623. The lateral fixing plate and the longitudinal positioning member 621 are both perpendicular to the substrate connecting plate 623. The lateral positioning member 622 and the longitudinal positioning member 621 are integrally formed with the substrate connecting plate 623. The substrate connecting plate 623 is detachably connected to the substrate 61.

[0235] Specifically, the substrate connecting plate 623 is provided with a snap-fit ​​protrusion 6231, and the substrate 61 is provided with a snap-fit ​​opening 614 that mates with the snap-fit ​​protrusion 6231. The substrate connecting plate 623 and the substrate 61 are detachably connected through the engagement of the snap-fit ​​protrusion 6231 and the snap-fit ​​opening 614. The substrate 61 has four snap-fit ​​openings 614 spaced at a predetermined distance along its upper side. The distance between the leftmost snap-fit ​​opening 614 and the left side of the substrate 61 is the same as the distance between the rightmost snap-fit ​​opening 614 and the right side of the substrate 61. The substrate connecting plate 623 is provided with three snap-fit ​​protrusions 6231 spaced at the predetermined distance. The substrate connecting plate 623 can snap-fit ​​with the three snap-fit ​​openings 614 on the left side of the substrate 61, or it can snap-fit ​​with the three snap-fit ​​openings 614 on the right side of the substrate 61.

[0236] In this embodiment, the substrate connecting plate 623 has snap-fit ​​protrusions 6231 on both its front and rear sides that mate with the snap-fit ​​opening 614. The snap-fit ​​opening 614 extends through the substrate 61. The snap-fit ​​protrusions 6231 on both the front and rear sides of the substrate connecting plate 623 allow the snap-fit ​​protrusions 6231 on the front of the substrate 61 to be snapped into the snap-fit ​​opening 614, and vice versa. When the substrate positioning structure 62 is used to position the substrate 61, both the transverse positioning member 622 and the longitudinal positioning plate are located at the corner 613 of the substrate 61.

[0237] Combination Figures 4 to 12 , Figure 17 The substrate 61 in this embodiment also includes a first mounting position and a second mounting position as described in the first to third and sixth embodiments for positioning the fixing members 4 on the left and right sides of the same door panel 31. The switching between the first mounting position and the second mounting position is achieved by translating the substrate 61 left and right.

[0238] Specifically, when the substrate 61 is in the first mounting position, the second side 612 of the substrate is attached to the door panel 31, the substrate positioning structure 62 is located at the upper left corner 6131 of the substrate 61, the longitudinal positioning member 621 is used to abut against the upper side wall of the door panel 31 so that the upper side of the substrate 61 is coplanarly aligned with the upper side wall of the door panel 31, and the transverse positioning member 622 is used to abut against the left side wall of the door panel 31 so that the left side of the substrate 61 is coplanarly aligned with the left side wall of the door panel 31.

[0239] When the substrate 61 is in the second mounting position, the substrate positioning structure 62 is located at the upper right corner 6132 of the substrate 61. The longitudinal positioning member 621 is used to abut against the upper side wall of the door panel 31 so that the upper side of the substrate 61 is coplanarly aligned with the upper side wall of the door panel 31. The transverse positioning member 622 is used to abut against the right side wall of the door panel 31 so that the right side of the substrate 61 is coplanarly aligned with the right side wall of the door panel 31.

[0240] In addition, in this embodiment, the substrate positioning structure 62 can be connected to the substrate 61 via a pre-fracture structure. Specifically, the edge of the substrate connecting plate 623 and the edge of the substrate 61 are connected via the pre-fracture structure. When the substrate positioning structure 62 is needed to position the substrate 61, the pre-fracture structure between the substrate positioning structure 62 and the substrate 61 is first broken, and then the snap-fit ​​protrusion 6231 of the substrate connecting plate 623 is snapped into the snap-fit ​​opening 614 of the substrate 61.

[0241] The fixing positioning structure 63 in this embodiment is quite different from the previous embodiments, and will be described in detail below.

[0242] In this embodiment, the substrate 61 includes a mounting portion 610. The fixing member positioning structure 63 includes a connecting portion 635, which is detachably connected to the mounting portion 610. The fixing member positioning structure 63 includes a positioning portion 636. The positioning portion 636 is used to position the fixing member 4 on the door panel 31.

[0243] In this embodiment, the mounting portion 610 includes a first mounting portion 6101 and a second mounting portion 6102 located in different areas of the substrate 61. The connecting portion 635 can switch between the first mounting portion 6101 and the second mounting portion 6102. With this configuration, the fasteners 4 in different areas of the door panel 31 can be mounted by switching the position of the fastener positioning structure 63.

[0244] In this embodiment, the second side 612 of the substrate is used to abut against the door panel 31, and the substrate 61 has a mounting opening 6103 connecting the first side 611 and the second side 612. A mounting portion 610 is disposed on the first side 611 of the substrate and located at the edge of the mounting opening 6103. When the connecting portion 635 is connected to the mounting portion 610, the positioning portion 636 is located in the area of ​​the mounting opening 6103. By placing the mounting portion 610 on the first side 611 of the substrate, interference between the mounting portion 610 and the second side 612 abutting against the door panel 31 can be avoided. By placing the positioning portion 636 in the area of ​​the mounting opening 6103, it is advantageous for the fastener 4 to be mounted from the first side 611 or the second side 612 of the substrate through the mounting opening 6103 onto the positioning portion 636.

[0245] In this embodiment, the mounting opening 6103 includes a first side 61031 and a second side 61032 facing each other. The first mounting portion 6101 is close to the first side 61031, and the second mounting portion 6102 is close to the second side 61032. The first mounting portion 6101 and the connecting portion 635 are detachably and slidably engaged. The second mounting portion 6102 and the connecting portion 635 are also detachably and slidably engaged. This sliding engagement facilitates the movement and disassembly of the positioning portion 636.

[0246] In this embodiment, the mounting opening 6103 includes a third side 61033 and a fourth side 61034 opposite to each other. The third side 61033 and the fourth side 61034 connect the first side 61031 and the second side 61032. The first mounting portion 6101 includes a first groove and a second groove symmetrically arranged on the third side 61033 and the fourth side 61034. The second mounting portion 6102 includes a third groove and a fourth groove symmetrically arranged on the third side 61033 and the fourth side 61034. The positioning portion 636 includes a first end 6361 and a second end 6362 opposite to each other. The connecting portion 635 includes a first slider 6351 and a second slider 6352 symmetrically arranged on the first end 6361 and the second end 6362. The first slider 6351 is detachably slidably engaged with the first groove and the third groove. The second slider 6352 is detachably slidably engaged with the second groove and the fourth groove. By cooperating with the symmetrical sliding grooves on both sides of the mounting opening 6103 and the symmetrical sliding blocks on both sides of the positioning part 636, a stable and reliable sliding fit between the positioning part 636 and the mounting part 610 can be achieved.

[0247] In this embodiment, the first mounting portion 6101 includes a first positioning wall 6104 disposed on the first side 61031. The first positioning wall 6104 closes the first side 61031 end portion of the first slide groove and the second slide groove. The second mounting portion 6102 includes a second positioning wall 6105 disposed on the second side 61032. The second positioning wall 6105 closes the second side 61032 end portion of the third slide groove and the fourth slide groove. The second side 61032 end portion of the first slide groove and the second slide groove is open. The first side 61031 end portion of the third slide groove and the fourth slide groove is open. The positioning portion 636 includes an opposing third side 61033 and a fourth end 6364. The third end 6363 and the fourth end 6364 are located between the first end 6361 and the second end 6362. The distance between the first mounting portion 6101 and the second mounting portion 6102 is greater than the distance between the third end 6363 and the fourth end 6364.

[0248] By providing open sections at the opposite ends of the first mounting portion 6101 and the second mounting portion 6102, the positioning portion 636 can be disengaged from the mounting portion 610 through the space between the first mounting portion 6101 and the second mounting portion 6102. By providing positioning walls at the mutually distant ends of the first mounting portion 6101 and the second mounting portion 6102, the positioning portion 636 can be positioned and limited, ensuring accurate positioning of the positioning portion 636.

[0249] Combination Figures 7 to 12 The specific positioning structure of the positioning part 636 in this embodiment can be as described in the second and third embodiments. Specifically, the positioning part 636 includes a positioning groove 632. The positioning groove 632 has a contour that matches the shape of the fixing member 4. The positioning groove 632 has a first mounting opening 6321. The first mounting opening 6321 communicates the positioning groove 632 with the second side 612 of the substrate, so that the fixing member 4 can be inserted into or disengaged from the second side 612 of the substrate. The positioning part 636 includes a positioning protrusion 633. The positioning protrusion 633 is disposed on the circumferential inner wall of the positioning groove 632 and is used for interference fit with the fixing member 4.

[0250] In this embodiment, the positioning groove 632 has a limiting wall 6320 spaced apart from the first assembly opening 6321. The limiting wall 6320 is used to prevent the fastener 4 inserted into the positioning groove 632 from coming out of the first side 611 of the substrate. The limiting wall 6320 is provided with a fastener clearance hole 6311, which is used to allow the fastener 5 that fixes the fastener 4 to pass through completely.

[0251] Combination Figures 13 to 16 In other embodiments, the positioning groove 632 may also have a second mounting opening 6322, as described in embodiments four and five. The second mounting opening 6322 communicates the positioning groove 632 with the first side 611 of the substrate, so that the fastener 4 can be inserted into or removed from the positioning groove 632 from the first side 611 of the substrate.

[0256] In this embodiment, the substrate 61 may include a lateral mounting opening 61035 extending from left to right. Part of the lateral mounting opening 61035 is located on the left side of the substrate 61, and another part is located on the right side of the substrate 61.

[0257] The substrate 61 includes a lateral mounting portion 6106 disposed at the edge of the lateral mounting opening 61035.

[0292] The refrigeration equipment in this application can be a refrigerator, freezer, etc.

[0293] In summary, the installation fixture (6) for the door panel (31) of the embedded refrigeration device (1) and the door assembly of the embedded refrigeration device (1) of this application can solve the problems of complex structure, high manufacturing cost, low installation efficiency and complicated operation of existing embedded refrigeration devices during the installation process.

[0294] The technical solution of this application can significantly improve the positioning accuracy and installation efficiency of the connector on the door panel, and has the following beneficial effects.

[0295] First, by setting up a base plate, a base plate positioning structure, and a fastener positioning structure, the tooling achieves rapid and accurate positioning of the connectors on the door panel, avoiding human error caused by traditional scribing and measurement methods. Especially under millimeter-level precision requirements, it can effectively improve the appearance consistency of the door panel and cabinet door after connection, ensuring that the gap between the door panel and the cabinet is uniform and aesthetically pleasing.

[0296] Secondly, the tooling supports multiple installation positions, allowing the substrate to be flipped up and down, left and right, and forward and backward. Through its detachable, sliding, and adjustable structural design, the same tooling can be used to position connectors at different positions on the top, bottom, left, and right of the door panel, and can also be applied to the installation needs of door panels with different structures and sizes, significantly improving the versatility and adaptability of the tooling.

[0297] Furthermore, the tooling offers various types of fixing and positioning structures, such as positioning plates integrally formed with the base plate through a pre-fractured structure, interference fit structures with positioning grooves and protrusions, and detachable structures with slider-groove fits. Different positioning methods are compatible with different types of connectors, ensuring reliable installation and convenient operation, and meeting diverse field application needs.

[0298] Furthermore, the tooling features a compact overall structure, enabling miniaturized design and making it suitable for efficient use in mass production environments and installation stations. Combined with the symmetrical arrangement on the base plate and appropriate installation markings (such as "L", "R", or refrigeration / freezing differentiation indicators), it avoids left-right mixing and incorrect installation positions, further improving assembly efficiency and reliability.

[0299] It is worth mentioning that the tooling is also equipped with a pre-storage structure for fasteners, which facilitates the pre-positioning and on-site retrieval of screws and other connecting parts, improving convenience and work efficiency in actual use. At the same time, for situations where there are dimensional tolerances in the door panel, the tooling can make fine adjustments through a sliding structure or an adjustable positioning structure to compensate for dimensional errors and ensure the integrity and visual effect of the door panel after assembly with the whole machine.

[0300] In summary, the installation fixture provided in this application has many advantages, such as high positioning accuracy, simple operation, strong adaptability, compact structure, and low manufacturing cost. It can effectively solve common problems in the installation of embedded refrigeration equipment door panels and improve assembly efficiency and quality.

[0301] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0302] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this patent, and are not intended to limit the scope of protection of this patent. All equivalent implementation methods or modifications that do not depart from the spirit of the technology of this patent should be included within the scope of protection of this patent.

10. The installation fixture (6) as described in claim 8, characterized in that, Both the first longitudinal positioning member and the first transverse positioning member are connected to the first substrate (651) through a thin film hinge structure. Both the first transverse positioning member and the first longitudinal positioning member can switch between a coplanar state with the first substrate (651) and a perpendicular state. A first snap-fit ​​structure is provided between the first transverse positioning member and the first longitudinal positioning member. The first snap-fit ​​structure is used to fix the first transverse positioning member and the first longitudinal positioning member in a state perpendicular to the first substrate (651). Both the second longitudinal positioning member and the second transverse positioning member are connected to the second substrate (661) through a thin film hinge structure. Both the second transverse positioning member and the second longitudinal positioning member can switch between a coplanar state with the second substrate (661) and a perpendicular state. A second snap-fit ​​structure is provided between the second transverse positioning member and the second longitudinal positioning member. The second snap-fit ​​structure is used to fix the second transverse positioning member and the second longitudinal positioning member in a state perpendicular to the second substrate (661).
