Description

Technical Field

[0001] This utility model relates to the field of refrigerators, and in particular to a wire harness positioning structure and a refrigerator thereof. Background Technology

[0002] In modern refrigerator manufacturing, the wiring harness is a key component connecting the top circuit board to various functional modules, and its installation and positioning accuracy directly affects the product's reliability and production efficiency. The current technical solution involves creating a circular through-hole in the refrigerator's top panel and installing a base. The wiring harness is then fitted with a circular clip and passes through the base, relying on gravity for basic fixation.

[0003] However, the lack of angular limiting between the clips and the base means that the clips and the base cannot maintain a specific installation angle, resulting in uncontrollable wire harness position during the subsequent foaming process. Furthermore, the limiting strength of the clips and the base is insufficient, and during the foaming process of the housing, the unfixed wire harness is prone to displacement due to the expansion pressure of the foaming material, affecting product quality. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a wire harness positioning structure.

[0005] A wire harness positioning structure for use in a refrigerator includes: a buckle, which is hollow, with its inner wall used to fix the wire harness and a limiting protrusion protruding from its outer wall; and a base connected to the refrigerator body, which is hollow and has a limiting groove on its inner wall, with the buckle snapping into the base and the limiting protrusion engaging with the limiting groove.

[0006] This design allows the wiring harness positioning structure to achieve circumferential angular positioning between the buckle and the base. By setting a limiting protrusion on the hollow outer wall of the buckle and a corresponding limiting groove on the inner wall of the base that connects to the refrigerator body, the limiting protrusion and the limiting groove can engage with each other when the buckle is engaged with the base. This effectively prevents the wiring harness from rotating after installation and solves the problem of uncontrollable wiring harness angle in existing technologies. At the same time, the engagement also provides radial constraint, enhancing the connection strength and stability of the overall structure and enabling it to better resist impacts and pressures generated during processes such as foaming.

[0007] In one embodiment, at least a portion of the buckle and at least a portion of the base are both configured as hollow cylindrical structures.

[0008] In one embodiment, multiple limiting protrusions are provided and spaced apart along the outer peripheral wall of the buckle, and multiple limiting grooves are provided and corresponding one-to-one with the limiting protrusions.

[0009] In one embodiment, four limiting protrusions are provided and are evenly spaced at 90° intervals relative to the axis of the buckle, and four limiting grooves are provided and are evenly spaced at 90° intervals relative to the axis of the base.

[0010] In one embodiment, the buckle has a plurality of first slots along the axial direction, and the first slots are located between two adjacent limiting protrusions.

[0011] In one embodiment, along the axial direction of the latch, one end of the latch is provided with a flange that protrudes outward along the radial direction of the latch and abuts against the end of the base; and / or, along the axial direction of the latch, the other end of the latch is provided with a flange that protrudes outward along the radial direction of the latch and abuts against the other end of the base.

[0012] In one embodiment, the base includes a connecting portion and an extension portion connected to each other. The extension portion extends radially outward along the axis of the base, and the outer diameter of the extension portion is larger than the outer diameter of the connecting portion.

[0013] In one embodiment, the connecting portion is provided with a plurality of gap grooves, all of which extend along the axial direction of the connecting portion, and the gap grooves are arranged in pairs, with a movable section formed between the two corresponding gap grooves, and the movable section is provided with the limiting groove.

[0014] In one embodiment, the extension is provided with a boss on the side away from the connecting portion. The boss extends along the circumferential edge of the extension and cooperates with the extension to form a positioning groove. One end of the buckle is provided with a flange that protrudes outward along the radial direction of the buckle and abuts against the positioning groove.

[0015] This utility model also provides a refrigerator, including the wire harness positioning structure described above.

[0016] Compared to existing technologies, this new design solves the problem of angled wire harness positioning in existing technologies by interlocking the limiting protrusions on the outer wall of the buckle with the limiting grooves on the inner wall of the base. This achieves reliable fixing at multiple precise angles, effectively preventing quality issues caused by rotation or displacement of the wire harness during subsequent processes such as foaming. Furthermore, the structure, with its multiple evenly distributed limiting protrusions and grooves, elastic slots in the buckle, and a movable section with a gap groove in the base, collectively provides a smooth assembly feel and a robust locking effect. In summary, this improves the positioning accuracy, operational efficiency, and process stability of wire harness installation, thereby ensuring the reliability and consistency of refrigerator production.

[0027] Please see Figures 1-3 This utility model provides a wire harness positioning structure for use in refrigerators. Through the limiting connection between the buckle 10 and the base 20, the wire harness is provided with rotation and movement limits to ensure its stable position.

[0028] The wiring harness positioning structure includes a buckle 10 and a base 20. The buckle 10 is hollow, and its inner wall is used to fix the wiring harness. A limiting protrusion 11 is provided on the outer wall of the buckle 10. The base 20 is connected to the refrigerator body. The base 20 is hollow, and a limiting groove 21 is provided on the inner wall of the base 20. The buckle 10 is snapped into the base 20, and the limiting protrusion 11 is snapped into the limiting groove 21. With this configuration, the wiring harness positioning structure features a limiting protrusion 11 on the outer wall of the hollow buckle 10 and a corresponding limiting groove 21 on the inner wall of the base 20 connected to the refrigerator body. This allows the limiting protrusion 11 and the limiting groove 21 to engage with each other when the buckle 10 is engaged with the base 20, thereby achieving circumferential angular positioning between the buckle 10 and the base 20. This effectively prevents the wiring harness from rotating after installation and solves the problem of uncontrollable wiring harness angles in existing technologies. At the same time, the engagement also provides radial constraint, enhancing the overall structural connection strength and stability, enabling it to better resist impacts and pressures generated during processes such as foaming.

[0029] In addition, after the buckle 10 extends into the base 20, it can quickly limit the position through the snap-fit ​​of the limiting protrusion 11 and the limiting groove 21, thereby realizing the quick assembly of the buckle 10 and the base 20 and improving the installation efficiency of the snap-fit ​​limiting of the internal wiring harness of the refrigerator.

[0030] Furthermore, at least a portion of the snap fastener 10 and at least a portion of the base 20 are both configured as hollow cylindrical structures. This allows the wire harness to pass through smoothly, and the cylindrical mating surface facilitates the smooth insertion and centering of the snap fastener 10 into the base 20, simplifying the installation process. This symmetrical structure also provides a basis for achieving uniform circumferential positioning and is easier to manufacture.

[0031] Specifically, multiple limiting protrusions 11 are provided and spaced along the outer peripheral wall of the buckle 10, and multiple limiting grooves 21 are provided and corresponding one-to-one with the limiting protrusions 11. In this way, by providing multiple limiting protrusions 11 spaced along the outer peripheral wall of the buckle 10 and multiple limiting grooves 21 corresponding to them on the inner wall of the base 20, a multi-point limiting fit is formed, which increases the contact area and biting force of the snap-fit, making the angle positioning more reliable and stable, effectively preventing wear or failure caused by single-point stress concentration, and improving the structure's resistance to rotation under vibration or external force.

[0032] Furthermore, four limiting protrusions 11 are provided, evenly spaced at 90° intervals relative to the axis of the latch 10, and four limiting grooves 21 are provided, evenly spaced at 90° intervals relative to the axis of the base 20. This achieves four-way symmetrical positioning. This not only ensures that the latch 10 obtains a clear positioning point every 90° rotation, providing precise multi-angle positioning options to meet the needs of different installation directions, but also ensures that the latch 10 is subjected to uniform force at any positioning angle, avoiding structural deformation or damage caused by uneven loading.

[0033] Understandably, in other embodiments, the limiting protrusions 11 can also be set to 2, 3 or 6, etc., all of which can achieve multi-level limiting adjustment, and are not limited to the above four schemes. In fact, the cooperation of one limiting protrusion 11 and one limiting groove 21 can achieve the basic technical effect.

[0034] The snap fastener 10 has multiple first slots 12 along its axial direction, and a first slot 12 is also present between two adjacent limiting protrusions 11. This gives the snap fastener 10 a certain elastic deformation capability. During installation, the snap fastener 10 can be radially compressed and contracted, allowing the limiting protrusions 11 to slide smoothly across the inner wall of the base 20. When the protrusion reaches the limiting groove 21, the snap fastener 10 springs back, and the protrusion engages in the groove to complete the locking. This simplifies the assembly operation, achieving reliable snap-fit ​​locking without additional tools, while also ensuring ease of disassembly.

[0035] Furthermore, along the axial direction of the latch 10, one end of the latch 10 is provided with a flange 13. The flange 13 protrudes outward along the radial direction of the latch 10 and abuts against the end of the base 20. Thus, after the latch 10 is installed in place, the flange 13 will deform outward from the inside of the base 20 and abut against the upper end of the base 20, thereby preventing the latch 10 from coming out of the base 20.

[0036] Alternatively, along the axial direction of the latch 10, the other end of the latch 10 is provided with a flange 14, which protrudes outward along the radial direction of the latch 10 and abuts against the other end of the base 20. In this way, the flange 14 can abut against the lower end face of the base 20, preventing the latch 10 from dislodging from the upper side of the base 20. The aforementioned flange 13 and flange 14 can function individually or together to improve the installation stability of the latch 10 and the base 20.

[0037] The base 20 includes a connecting portion 22 and an extension portion 23, which are connected. The extension portion 23 extends radially outward along the axis of the base 20, and its outer diameter is larger than that of the connecting portion 22. This larger outer diameter of the extension portion 23 increases the contact area between the base 20 and the refrigerator body, thereby improving the installation stability and load-bearing capacity of the base 20 on the refrigerator body.

[0038] Furthermore, the connecting portion 22 is provided with multiple gap grooves 221, all of which extend along the axial direction of the connecting portion 22. The gap grooves 221 are arranged in pairs, forming a movable section 222 between two corresponding gap grooves 221. A limiting groove 21 is provided on the movable section 222. This gives the movable section 222 a certain degree of radial elasticity. When the limiting protrusion 11 of the latch 10 is pressed in, the movable section 222 can undergo slight elastic deformation to allow the protrusion to pass through, and then spring back to lock after the protrusion is engaged in the limiting groove 21. This design, in conjunction with the first slot 12 on the latch 10, further optimizes the smoothness of the engagement process and the final locking stability.

[0039] Furthermore, a boss 231 is provided on the side of the extension 23 away from the connecting part 22. The boss 231 extends along the circumferential edge of the extension 23 and cooperates with the extension 23 to form a positioning groove 232. One end of the latch 10 is constructed with a flange 13, which protrudes outward along the radial direction of the latch 10 and abuts against the positioning groove 232. In this way, the flange 13 at the end of the latch 10 abuts against the positioning groove 232, achieving precise definition and secure locking of the axial position of the latch 10. The positioning groove 232 structure provides a clear space for receiving and supporting the flange 13, enhancing the reliability of axial positioning and preventing the latch 10 from moving axially.

[0040] Furthermore, preferably, the aforementioned limiting protrusion 11 is configured as a hemispherical protrusion, and the limiting groove 21 is also configured as a hemispherical groove structure, so that the fit between the limiting protrusion 11 and the limiting groove 21 is smoother.

[0041] This utility model also provides a refrigerator, including the wire harness positioning structure described above.

[0042] Compared to existing technologies, this new design solves the problem of angle positioning for wire harnesses by interlocking the limiting protrusions 11 on the outer wall of the buckle 10 with the limiting grooves 21 on the inner wall of the base 20. This achieves reliable fixing at multiple precise angles, effectively preventing quality issues caused by rotation or displacement of the wire harness during subsequent processes such as foaming. Furthermore, the structure, through the arrangement of multiple evenly distributed limiting protrusions 11 and limiting grooves 21, the elastic slots of the buckle 10, and the movable section 222 of the base 20 with gap grooves 221, collectively provides a smooth assembly feel and a robust interlocking effect. In summary, this improves the positioning accuracy, operational efficiency, and process stability of wire harness installation, thereby ensuring the reliability and consistency of refrigerator production.

[0043] The refrigerator equipped with the wiring harness positioning structure has an intelligent voice control module. The intelligent voice control module includes a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the refrigerator to perform corresponding operations, thereby realizing intelligent control of the refrigerator and improving the user experience of using this intelligent appliance.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
