Description

Technical Field

[0001] This application relates to the field of refrigeration equipment manufacturing technology, for example to an auxiliary tooling for a main control box and the main control box. Background Technology

[0002] Currently, during refrigerator assembly, some terminals and wire harnesses of the cabinet cables pass through the main control box. Since the cabinet bulges during foaming, the foaming mold is used to secure the entire cabinet to prevent deformation. Because the foaming mold is based on the back side, to prevent damage to the power cord on the main control box cover, related technologies typically use tape to secure the power cord inside the main control box before foaming begins. After foaming, the tape is removed to install the main control board and other materials.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] In related technologies, the power cord must be passed through the main control box before it can be secured with tape. In addition, the tape needs to be removed after foaming, and the removed tape cannot be used, which is quite wasteful.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0041] Combination Figures 1 to 9 As shown, this embodiment of the present disclosure provides an auxiliary tooling for a main control box. The main control box 10 defines a receiving cavity 13 with an opening 14. The auxiliary tooling for the main control box includes a fixing plate 20, which is configured with a wire harness groove. The fixing plate 20 is adapted to be disposed in the receiving cavity 13. The wire harness groove is used to enclose a wire harness cavity 27 with the main control box 10. The wire harness cavity 27 is used to fix the wire harness. The fixing plate 20 is adapted to be detachably connected to the main control box 10.

[0042] In this embodiment, the receiving cavity 13 of the main control box 10 is used to house power cords, etc. The fixing plate 20 is located within the receiving cavity 13 and encloses the main control box 10 to form a wire harness cavity 27. The wire harness cavity 27 protects and constrains the wire harness, preventing it from being crushed or damaged by the foaming mold during the foaming process. During the foaming process, the wire harness is hidden within the wire harness cavity 27. After the foamed box solidifies and forms overall strength, the wire harness is then routed and terminals are connected.

[0043] Optionally, the fixing plate 20 is inserted into the receiving cavity 13 through the opening of the main control box 10. The fixing plate 20 and the bottom wall of the receiving cavity 13 enclose the wire harness cavity 27. At least one side of the wire harness cavity 27 facing the side wall of the receiving cavity is open to facilitate the wire harness entering the wire harness cavity 27.

[0044] Optionally, such as Figures 2 to 4 as well as Figure 6 and Figure 7 As shown, at least one end of the fixing plate 20 is provided with a hook 30 and an elastic element 50, and the main control box 10 is provided with a buckle 11. The hook 30 is used to detachably connect with the buckle 11. When the hook 30 is connected to the buckle 11, the elastic element 50 undergoes elastic deformation, and the elastic element 50 applies a force to the hook 30 to connect with the buckle 11, so as to restrict the buckle 11 from separating from the hook 30.

[0045] In this embodiment, the fixing plate 20 and the main control box 10 are detachably connected via hooks 30 and clips 11. This detachable connection using hooks 30 and clips 11 simplifies operation, facilitates manufacturing, and reduces cost. Furthermore, an elastic element 50 further strengthens the connection between the hooks 30 and clips 11. When connected, the elastic element 50 undergoes elastic deformation, applying force to the hooks 30. This effectively prevents separation of the clips 11 and hooks 30 during the foaming process, improving the reliability and stability of the connection between the fixing plate 20 and the main control box 10. This avoids loosening of the connection between the fixing plate 20 and the main control box 10 due to external impacts or vibrations, thus improving the anti-interference capability and service life of the main control box assembly.

[0046] Furthermore, the mounting plate 20 and the main control box 10 can be assembled before being assembled into the refrigeration equipment. This eliminates the need for additional operations once the main control box assembly is installed into the refrigeration equipment, improving production efficiency. After foaming is complete, the mounting plate 20 can be removed to facilitate the installation of components such as the main control board into the main control box 10. The removed mounting plate 20 can then be installed in other main control boxes 10, allowing for repeated use and reducing costs while expanding its application range.

[0047] Optionally, such as Figures 6 to 8 As shown, the fixed plate 20 has a movable notch 21, which connects the outside and inside of the wire harness groove. The hook 30 passes through the movable notch 21 and extends into the wire harness groove. The auxiliary tooling for the main control box also includes a rotating shaft 40, which is located at the movable notch 21. The hook 30 is rotatably located on the rotating shaft 40 and can rotate around the rotating shaft 40 so that the hook 30 can be connected to or separated from the buckle 11. The elastic element 50 is sleeved on the outside of the rotating shaft 40 and can be connected to the hook 30.

[0048] In this embodiment, the movable notch 21 provides movement space for the rotating shaft 40. The rotating shaft 40 not only provides an installation position for the hook 30 but also limits the direction of movement of the hook 30. Rotation of the hook 30 around the rotating shaft 40 as its rotation center enables the hook 30 to connect and separate from the latch 11, ensuring precise positioning and engagement between the hook 30 and the latch 11. The elastic element 50 is sleeved on the outside of the rotating shaft 40, eliminating the need for additional components to fix the elastic element 50. Furthermore, both the elastic element 50 and the hook 30 are fixed to the rotating shaft 40, ensuring that the elastic element 50 can effectively apply elastic force and preventing accidental separation of the hook 30 from the latch 11.

[0049] Optionally, the rotating shaft 40 is located on the side of the movable notch 21 facing the wire harness groove, so that both the rotating shaft 40 and the elastic element 50 are located inside the wire harness cavity, thus avoiding the rotating shaft and the elastic element being affected during foaming.

[0050] Optionally, the elastic element 50 can be a spring, an elastic sheet, or a shape memory alloy, etc.

[0051] Optionally, such as Figure 9 As shown, the elastic element 50 includes a spring coil 54, a first straight arm 52, and a second straight arm 53. The spring coil 51 is wound around the outside of the rotating shaft 40, and the spring coil 51 includes a spring wire, which is wound multiple times around the outside of the rotating shaft 40. The first straight arm 52 is connected to one end of the spring coil 51 and corresponds to the hook 30. The second straight arm 53 is connected to the other end of the spring coil 51 and corresponds to the fixing plate 20. When the hook 30 moves toward the direction of connection with the buckle 11, the first straight arm 52 moves away from the second straight arm 53, and the angle between the first straight arm 52 and the second straight arm 53 increases. When the hook 30 moves toward the direction of separation from the buckle 11, the first straight arm 52 moves toward the direction of proximity to the second straight arm 53, and the angle between the first straight arm 52 and the second straight arm 53 decreases.

[0052] In this embodiment, the structure of the spring coil 51, the first straight arm 52, and the second straight arm 53 of the elastic element 50 allows the elastic element 50 to generate appropriate elastic deformation during the movement of the hook 30. When the hook 30 is connected to the buckle 11, the elastic element 50 is in a compressed state, applying an elastic force with opposite movements to the hook 30 and the fixing plate 20, so that the hook 30 can be tightly locked with the buckle 11, further enhancing the stability of the connection; when the hook 30 is separated from the buckle 11, the elastic force of the elastic element 50 can help the hook 30 return to its original position, facilitating the next connection. Furthermore, when the fixing plate 20 is just installed into the receiving cavity 14, the hook 30 can quickly engage with the buckle 11 under the action of the elastic element 50 and be tightly connected to the buckle 11. In this way, the elastic element 50 not only plays a pre-tightening role, but also ensures the accuracy of the movement direction of the hook 30, ensuring the accurate installation of the hook and the buckle.

[0053] Optionally, the elastic element is a double-arm torsion spring.

[0054] Optionally, when the hook 30 is connected to the buckle 11, the first straight arm 52 abuts against or is connected to the hook 30, and the second straight arm 53 abuts against or is connected to the fixing plate 20. The angle between the first straight arm 52 and the second straight arm 53 is the first angle. When the elastic member 50 is in its natural state, the angle between the first straight arm 52 and the second straight arm 53 is the second angle. The first angle is smaller than the second angle.

[0055] In this embodiment, when the hook 30 is connected to the buckle 11, the angle between the first straight arm 52 and the second straight arm 53 is smaller than the angle between the first straight arm 52 and the second straight arm 53 in their natural state. Thus, when the buckle 11 is connected to the hook 30, the first straight arm 52 applies a force to the hook 30 in the direction of the buckle 11, so that the hook 30 and the buckle 11 can be tightly engaged. Furthermore, the elastic element 50 provides stable elastic support when the hook 30 and the buckle 11 are connected, and when the buckle 11 and the hook 30 are separated, the elastic element 50 can apply an elastic force to the hook 30 so that the hook 30 can quickly reset, thereby ensuring the stability and reliability of the connection between the hook 30 and the buckle 11.

[0056] Optionally, the elastic element and the hook 30 can always be connected, so that the relative position between the elastic element 50 and the hook 30 does not change, thus ensuring the movement stability of the hook 30. Alternatively, the elastic element and the hook 30 can abut against each other, which also ensures that the elastic element 50 applies force to the hook 30.

[0057] Optionally, the first straight arm 52 is connected to the hook 30; for example, the first straight arm and the hook are welded or glued together.

[0058] Optionally, the second straight arm 53 is connected to the fixed plate 20 to ensure the positional stability of the second straight arm 53. Alternatively, the second straight arm 53 abuts against the fixed plate 20, which also allows the fixed plate to restrict the elastic element and ensure the elastic force of the elastic element.

[0059] Optionally, the second straight arm 53 abuts against or connects to the wall of the fixing plate 20 facing the wire harness groove.

[0060] Optionally, the fixing plate 20 includes a fixing plate body and a connecting plate 211. The fixing plate body has a movable notch 21. Two connecting plates 211 are respectively provided on both sides of the movable notch 21. Both connecting plates 211 have connecting holes 212. The two ends of the rotating shaft 40 are located in the two connecting holes 212. The elastic element 50 and the hook 30 are both located between the two connecting plates 211.

[0061] In this embodiment, the rotating shaft 40 is installed via the connecting plate 211 and the connecting hole 212, providing a stable mounting platform for the hook 30 and the elastic element 50. This structure makes the installation of the rotating shaft 40, hook 30, and elastic element 50 more secure, while facilitating assembly and disassembly, thus improving production efficiency.

[0062] Optionally, the hook 30 includes a hook body and a reinforcing rib 33. The two reinforcing ribs 33 are located on both sides of the hook body. The reinforcing ribs 33 have a rotating hole 34. The rotating shaft 40 passes through the rotating hole 34 so that the hook 30 can rotate around the rotating shaft 40. The reinforcing ribs 33 are located between the two connecting plates 211, and the elastic element 50 is located between the two reinforcing ribs 33.

[0063] In this embodiment, the reinforcing rib 33 increases the strength of the hook 30, preventing deformation. The reinforcing rib 33 also features a rotating hole 34 through which the rotating shaft 40 passes, thus achieving a rotatable connection between the hook 30 and the rotating shaft 40, ensuring smooth rotation of the hook 30. The reinforcing rib 33 is located between the two connecting plates 211, preventing interference between the hook 30 and the connecting plates 211. The elastic element 50 is located between the two reinforcing ribs 33, providing sufficient installation space to ensure the elasticity of the elastic element 50 and its cooperation with the hook 30 and the fixing plate 20.

[0064] Optionally, the reinforcing ribs 33 are spaced apart from the connecting plate 211. This prevents the rotation of the hook from interfering with the connecting plate.

[0065] Optionally, the rotating hole 34 corresponds to the connecting hole 212, and the opening area 14 of the rotating hole 34 is the same as the opening area 14 of the connecting hole 212. This ensures that the rotating shaft 40 can accurately pass through the connecting hole 212 and the rotating hole 34 during installation, while avoiding assembly errors or loosening caused by dimensional mismatch. This improves the accuracy and reliability of the assembly, and also ensures the stability of the hook 30 during rotation, reducing additional stress or wear caused by shaking or excessive clearance.

[0066] Optionally, the outer diameter of the spring coil 51 is larger than the inner diameter of the rotating hole 34. This prevents the spring coil 51 from falling out of the rotating hole 34.

[0067] Optionally, the minimum distance from the rotating shaft 40 to the hook 30 is greater than the outer diameter of any of the spring wires of the spring coil 51. This allows sufficient space between the hook 30 and the rotating shaft 40 to install the spring coil, avoiding interference between the spring coil and the hook 30.

[0068] Optionally, such as Figure 9As shown, the length of the rotating shaft 40 is greater than the distance between the two connecting plates 211, and the two ends of the rotating shaft 40 pass through the connecting holes 212 and form a bent structure 41.

[0069] In this embodiment of the disclosure, the bending structure 41 can ensure that the rotating shaft 40 is firmly fixed in the connecting hole 212, preventing it from loosening or falling off during use.

[0070] Optionally, the fixing plate includes a first side plate 23, a second side plate 24, and a third side plate 25. The second side plate 24 is connected to one end of the first side plate 23 and extends toward one side in the thickness direction of the first side plate 23. A movable notch is provided at the connection between the second side plate 24 and the first side plate 23. The third side plate 25 is connected to the other end of the first side plate 23 and extends toward the other side in the thickness direction of the first side plate 23. An extension hole is provided at the connection between the third side plate 25 and the first side plate 23. When the hook 30 is connected to the buckle 11, the extension hole 22 is adapted to correspond to the buckle 11. The hook 30 includes a movable part 31 and a connecting part 32. The movable part 31 extends into the wire harness groove through the movable notch. The first end of the movable part 31 is located on the side of the movable notch facing away from the wire harness groove. The connecting part 32 is connected to the second end of the movable part 31 and can extend out from the extension hole 22 for connection or separation with the buckle 11.

[0071] In this embodiment, the first side plate 23, the second side plate 24, and the third side plate 25 facilitate the setting of movable notches and protrusion holes, thereby enabling the hook 30 to be stably installed on the fixed plate and ensuring the movement space and accuracy of the hook 30. Furthermore, the structure of the first side plate 23, the second side plate 24, and the third side plate 25 also improves the strength and bending resistance of the fixed plate, ensuring that the fixed plate is not easily deformed during the foaming process. The first end of the movable part 31 of the hook 30 is exposed on the side of the fixed plate 20 opposite to the wire harness groove through the movable notch 21, making it convenient for the user to apply force to the hook 30. The movable part 31 also passes through the movable notch 21 into the wire harness groove, and a connecting part 32 is connected to the second end of the movable part 31. The connecting part 32 extends out of the wire harness cavity 27 through the protrusion hole 22, so that the connecting part 32 can be connected to or separated from the buckle 11.

[0072] Optionally, when the buckle and the hook are connected, the first side plate 23 extends along the height direction of the receiving cavity 13. The first side plate 23 has a movable notch 21 at one end facing the opening 14, and an extension hole 22 at the other end away from the opening 14. The extension hole 22 corresponds to the buckle 11. The movable part 31 extends into the wire harness cavity 27 through the movable notch 21. The first end of the movable part 31 is located on the side of the movable notch 21 facing the opening 14. The connecting part 32 is connected to the second end of the movable part 31 and extends out from the extension hole 22 to be connected to or separated from the buckle 11.

[0073] In this embodiment, the first side plate 23 extends along the height direction of the receiving cavity 13, so that the movable part 31 of the hook 30 can be located close to the opening 14, which facilitates the operation of the hook 30.

[0074] Optionally, when the elastic element 50 includes a first straight arm 52 and a second straight arm 53, the first straight arm 52 is connected to the movable part 31 of the hook 30, and the second straight arm 53 is connected to or abuts against the wall of the first side plate 23 facing the wire harness cavity. Thus, when the movable part 31 is located at the end outside the wire harness cavity, the movable part 31 located inside the wire harness cavity moves towards the first side plate 23, reducing the angle between the first straight arm 52 and the second straight arm 53, allowing the hook 30 to disengage from the latch 11. After the hook 30 is released, the first straight arm 52 drives the hook 30 to move away from the first side plate 23, connecting the hook 30 to the latch 11. Even after the hook 30 is connected to the latch 11, the angle between the first straight arm 52 and the second straight arm 53 remains smaller than the angle between the first straight arm 52 and the second straight arm 53 in their natural state. The elastic element 50 can continuously apply force to the hook 30, ensuring the tightness of the connection between the hook 30 and the latch 11.

[0075] Optionally, when the buckle and the hook are connected, the movable part 32 extends along the height direction of the receiving cavity, and the connecting part 32 extends along the width or length direction of the receiving cavity. This makes it easy for the user to operate the movable part 32, and easy for the connecting part 32 to be connected to or attached to the buckle 11.

[0076] Optionally, reinforcing ribs are provided on both sides of the movable part 31, that is, the movable part 31 can rotate around the rotation axis, thereby enabling the movable part 31 to drive the connecting part 32 to move, so that the connecting part can be connected or separated from the buckle 11.

[0077] Optionally, the buckle 11 is provided on the bottom wall of the receiving cavity 13. When the fixing plate 20 is installed in the receiving cavity 13, the buckle 11 is located on one side of the fixing plate 20. The second side plate 24 is connected to the end of the first side plate 23 facing the opening 14 and extends away from the buckle 11. The third side plate 25 is connected to the end of the first side plate 23 away from the second side plate 24 and extends towards the buckle 11. The connection between the second side plate 24 and the first side plate 23 is provided with a movable notch 21, and the connection between the third side plate 25 and the first side plate 23 is provided with an extension hole 22, which extends along the extension direction of the third side plate 25.

[0078] In this embodiment, the second side plate 24 extends away from the buckle 11, forming a bend-resistant protective top cover for the wire harness cavity 27 to resist external downward pressure. The third side plate 25 extends towards the buckle 11, forming a locking mechanism protective cover to prevent foreign objects from impacting the connection part 32. Furthermore, the second side plate 24 and the third side plate 25 provide additional support for the fixing plate 20 by facilitating the setting of the movable notch 21 and the protruding hole 22, enhancing the overall structural strength of the fixing plate 20. Simultaneously, the precise setting of the movable notch 21 and the protruding hole 22 ensures the stability of the hook 30 during connection and separation, reducing the risk of connection loosening due to external impact or vibration.

[0079] Optionally, when the latch 11 is connected to the hook 30, the latch 11 is located on the side of the hook 30 facing the opening 14. This prevents the hook 30 from separating from the latch 11.

[0080] When it is necessary to disassemble the fixing plate 20, rotate the hook 30 toward the buckle 11, that is, move the first end of the movable part 31 toward the buckle 11. In this way, the hook 30 rotates around the rotating shaft 40, and the connecting part 32 moves away from the buckle 11. When the connecting part 32 disengages from the buckle 11, the fixing plate 20 can be separated from the receiving cavity 13.

[0081] Optionally, the latch 11 includes a latching post and a latching protrusion. One end of the latching post is connected to the bottom wall of the receiving cavity, and the latching protrusion is connected to the other end of the latching post. A latching space is provided below the latching protrusion. When the hook 30 is connected to the latch 11, the end of the hook 30 is located in the latching space, and the hook abuts against the latching protrusion, thus realizing the connection between the hook 30 and the latch 11.

[0083] In this embodiment, the first end of the fixing plate 20 is provided with a hook 30 and an elastic element 50, and the second end is provided with a latching protrusion 26 or a latching groove 12. When the fixing plate 20 needs to be installed, the latching protrusion 26 at the second end is first connected to the latching groove 12. Then, the hook 30 at the first end of the fixing plate 20 can slide into the buckle 11 along the guide surface 111. After the buckle 11 is connected to the hook 30, the elastic element 50 can apply an elastic force to the hook 30, further ensuring the tightness of the connection between the hook 30 and the buckle 11 and preventing the hook 30 and the buckle 11 from separating. In addition, both the latching protrusion 26 and the latching groove 12 extend along the direction from the first end to the second end. In this way, during installation, the latching protrusion 26 and the latching groove 12 can be directly inserted in one direction. Furthermore, when operating the first end, the buckle 11 and the latching groove 12 will not separate. After the first end of the fixing plate 20 is fixed, it can also limit the connection of the second end, improving the tightness of the connection between the fixing plate 20 and the main control box 10.

[0084] After the main control box 10 is foamed, the hook 30 can be moved to separate the hook 30 from the buckle 11. This allows the first end of the fixing plate 20 to be separated from the main control box 10. Then, the latch protrusion 26 and the slot 12 at the second end of the fixing plate 20 can also be separated. This allows the fixing plate 20 to be removed and connected to other uninstalled main control boxes 10, enabling the fixing plate 20 to be reused, reducing costs and avoiding waste.

[0085] Optionally, the hook 30 is located at the middle of the first end of the fixing plate 20.

[0099] In this embodiment, when the auxiliary fixture for the main control box is installed in the receiving cavity, the wire harness groove of the fixing plate and the side wall of the main control box form a wire harness cavity, which can be used to fix the wire harness. The fixing plate and the main control box are detachably connected by clips and hooks. Thus, when foaming is required around the main control box, the auxiliary fixture can be installed into the receiving cavity to fix and protect the wire harness within. After the foaming around the main control box is completed, the auxiliary fixture can be disassembled and installed with other main control boxes. This allows the auxiliary fixture to be reused, improving production efficiency and reducing costs.
