Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a centering structure and a refrigerator. Background Technology

[0002] Built-in refrigerators are refrigerators designed to be integrated with kitchen cabinets, typically installed within the cabinetry for a cleaner, more unified, and aesthetically pleasing look. Since the refrigerator is inside the cabinet, maintaining a suitable gap between the refrigerator and the cabinetry is crucial for achieving the best visual effect. The industry standard typically includes a pre-installed centering mechanism on the refrigerator to control this gap.

[0003] However, the centering structure currently used in refrigerators is expensive, and most built-in refrigerator cabinets are made of wood, lacking sufficient support. In this case, attempting to adjust the lateral spacing after the refrigerator has been installed in the cabinet may cause the cabinet to warp, while the refrigerator itself is difficult to reposition. Summary of the Invention

[0004] This utility model provides a centering structure and a refrigerator to solve the defects of existing refrigerator centering structures that cannot effectively adjust the gap between the refrigerator and the cabinet, and that the cabinet is prone to deformation during adjustment.

[0005] This utility model provides a centering structure, including: a linear drive mechanism and two adjustment components.

[0006] The linear drive mechanism includes a drive assembly and a slide block. The slide block is configured to be slidably connected to the refrigerator body along a first direction. The drive assembly is connected to the slide block to drive the slide block to move along the first direction. Two adjustment assemblies are symmetrically arranged on both sides of the slide block. Each adjustment assembly includes a drive arm and an adjustment arm. A first end of the drive arm is hinged to the slide block, and a second end of the drive arm is hinged to the first end of the adjustment arm. The adjustment arm is configured to be slidably connected to the refrigerator body along a second direction to drive the adjustment arm to move along the second direction when the slide block moves along the first direction.

[0007] According to the centering structure provided by this utility model, the driving assembly includes a threaded driving member, which is threadedly connected to the slide block to drive the slide block to move along the first direction when the threaded driving member is rotated.

[0008] According to the centering structure provided by this utility model, the drive assembly further includes a fixed base, one end of the threaded drive member is connected to the fixed base, and the fixed base is configured to be fixedly connected to the refrigerator body.

[0009] According to the centering structure provided by this utility model, the fixed base is provided with a first limiting groove, and at least a portion of the threaded drive component cooperates with the first limiting groove. The first limiting groove is used to restrict the degree of freedom of the threaded drive component along the second direction.

[0010] According to the centering structure provided by this utility model, one end of the threaded drive member is provided with a joint portion, and the side wall of the fixed seat facing the joint portion is provided with a clearance opening.

[0011] According to the centering structure provided by this utility model, the second end of the adjusting arm is provided with a guide wheel.

[0012] According to the centering structure provided by this utility model, the guide wheel is a flexible guide wheel.

[0013] According to the centering structure provided by this utility model, it further includes a first limiting member, which is configured to be fixedly connected to the refrigerator body. A second limiting groove is formed on the first limiting member, and the slide is located in the second limiting groove to limit the movement of the slide along the first direction; and / or, it further includes a second limiting member, which is configured to be fixedly connected to the refrigerator body. A third limiting groove is formed on the second limiting member, and the adjusting arm is located in the third limiting groove to limit the movement of the adjusting arm along the second direction.

[0014] According to the centering structure provided by this utility model, the slide block is provided with a receiving groove at one end near the drive arm, and the first end of the drive arm is located in the receiving groove.

[0015] According to the centering structure provided by this utility model, the first direction and the second direction are perpendicular to each other.

[0016] In another aspect, this utility model provides a refrigerator, comprising: a cabinet and an alignment structure as described in any of the preceding claims, wherein the slide is slidably connected to the cabinet along a first direction, and the adjusting arm is slidably connected to the cabinet along a second direction.

[0017] According to the refrigerator provided by this utility model, the centering structure is located at the bottom of the cabinet.

[0018] The centering structure provided by this utility model, through the setting of a linear drive mechanism and two adjusting components, allows the sliding block to move along the first direction of the refrigerator during use. Simultaneously, the two drive arms drive the corresponding adjusting arms to move along the second direction of the refrigerator, extending the adjusting arms beyond the side wall of the refrigerator. By controlling the drive stroke of the drive components, the extension length of the adjusting arms can be precisely controlled. Thus, after the two adjusting arms extend to the set length, the refrigerator can be pushed into the kitchen cabinet. When the refrigerator is pushed in, the second ends of the two adjusting arms abut against the corresponding side wall of the kitchen cabinet, ensuring the refrigerator is accurately centered inside. Furthermore, the pressure exerted by the adjusting arms on the cabinet during the pushing process is very small, preventing damage to the cabinet. The refrigerator does not rub against the side wall of the kitchen cabinet during the pushing process, and no adjustments are required after the refrigerator is finally inside the cabinet, resulting in high reliability.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0035] The following is combined Figures 1 to 7 This invention describes the centering structure and refrigerator provided by this utility model.

[0036] See Figure 1 As shown, the centering structure provided in this embodiment of the present invention includes: a linear drive mechanism 100 and two adjustment components 200.

[0037] The linear drive mechanism 100 includes a drive assembly 110 and a slide 120. The slide 120 is configured to be slidably connected to the refrigerator body 500 along a first direction. The drive assembly 110 is connected to the slide 120 to drive the slide 120 to move along the first direction. Two adjustment assemblies 200 are symmetrically arranged on both sides of the slide 120. The adjustment assembly 200 includes a drive arm 210 and an adjustment arm 220. The first end of the drive arm 210 is hinged to the slide 120, and the second end of the drive arm 210 is hinged to the first end of the adjustment arm 220. The adjustment arm 220 is configured to be slidably connected to the refrigerator body 500 along a second direction to drive the adjustment arm 220 to move along the second direction when the slide 120 moves along the first direction.

[0038] It should be noted that both "first direction" and "second direction" mentioned above refer to... Figure 1The arrows shown indicate different directions. The first direction can be understood as the depth direction of the refrigerator, and the second direction can be the width direction of the refrigerator (in which case the second direction is perpendicular to the first direction), or it can be an inclined direction that has a component in the width direction of the refrigerator (in which case the second direction is greater than or less than 90° to the first direction), for example, an inclined direction towards the side away from or closer to the slide block 120. That is, the adjusting arm 220 can be set horizontally along the width direction of the refrigerator, or it can be inclined along the width direction of the refrigerator.

[0039] The centering structure provided by this utility model, through the setting of a linear drive mechanism 100 and two adjusting components 200, allows the following operation: During use, the drive component 110 drives the slide 120 to move along the first direction of the refrigerator, while the two drive arms 210 drive the corresponding adjusting arms 220 to move along the second direction of the refrigerator, extending the adjusting arms 220 beyond the side wall of the refrigerator. By controlling the drive stroke of the drive component 110, the extension length of the adjusting arms 220 can be precisely controlled. After the two adjusting arms 220 extend to the set length, the refrigerator can be pushed into the kitchen cabinet 600. When the refrigerator is pushed in, the second ends of the two adjusting arms 220 respectively abut against the corresponding side wall of the kitchen cabinet 600, ensuring the refrigerator is accurately centered within the cabinet. Furthermore, the pressure exerted by the adjusting arms 220 on the kitchen cabinet 600 during the pushing process is very small, preventing damage to the cabinet. The refrigerator does not rub against the side wall of the kitchen cabinet 600 during the pushing process, and no adjustment is required after the refrigerator is finally inside the cabinet, resulting in high reliability.

[0040] Specifically, the centering structure provided by this utility model includes a linear drive mechanism 100 and two adjusting components 200. The linear drive mechanism 100 includes a slide 120 and a drive component 110, which drives the slide 120 to move along a first direction. The two adjusting components 200 are symmetrically arranged on both sides of the slide 120, located on the left and right sides of the slide 120, respectively. Each adjusting component 200 includes a drive arm 210 and an adjusting arm 220. Since the slide 120 is configured to slide along the first direction and be slidably connected to the refrigerator body 500, and the adjusting arm 220 is configured to slide along the second direction and be slidably connected to the refrigerator body 500, when the slide 120 moves along the first direction, it can drive the two drive arms 210 to swing, and the second end of the drive arm 210 drives the corresponding adjusting arm 220 to move along the second direction.

[0041] See Figure 1As shown, when the slide 120 moves in the positive direction of the first direction under the action of the drive assembly 110, the two drive arms 210 respectively drive the two adjustment arms 220 to move in a direction away from each other, so that the two adjustment arms 220 can extend from both sides of the refrigerator and contact the inner wall of the kitchen cabinet 600; correspondingly, when the slide 120 moves in the negative direction of the first direction under the action of the drive assembly 110, the two drive arms 210 respectively drive the two adjustment arms 220 to move in a direction close to each other, so that the two adjustment arms 220 can retract inward from both sides of the refrigerator to complete the storage.

[0042] The drive assembly 110 can be implemented in various ways known in the prior art, such as a manual drive assembly 110 or an automatic drive assembly 110. The manual drive assembly 110 can be manually rotated, using mechanical structures such as gears or lead screws to drive the slide 120 to move along the first direction. The automatic drive assembly 110 can be powered by electric, pneumatic, or hydraulic means to drive the slide 120 to move along the first direction.

[0043] In addition, the drive component 110 may employ other methods known in the prior art, and there is no limitation thereto.

[0044] The length of the adjusting arm 220 can be limited according to actual needs. It should meet the following two requirements: First, when stored, both adjusting arms 220 should be located inside the corresponding side wall of the refrigerator, so as not to obstruct transportation or transfer; second, when extended, both adjusting arms 220 should extend to the outside of the corresponding side wall of the refrigerator. This ensures that when stored, it does not interfere with other components or occupy excessive space, and when extended, its second end can abut against the side wall of the kitchen cabinet 600. The specific length of the adjusting arm 220 can be set according to the refrigerator's specifications (width).

[0045] See Figures 1 to 3 As shown, according to some embodiments of the present invention, the drive assembly 110 includes a threaded drive member 111, which is threadedly connected to the slide 120 to drive the slide 120 to move in a first direction when the threaded drive member 111 is rotated.

[0046] By using a threaded drive component 111 to drive the slide 120, the adjustment accuracy of the adjusting arm 220 can be improved, the stability of the adjusting arm 220 during adjustment can be enhanced, and the operation can be simplified. Furthermore, the threaded adjusting component 111 has a self-locking characteristic; when the adjusting arm 220 is adjusted to the set position, it can achieve self-locking through the threaded connection between the threaded drive component 111 and the slide 120, eliminating the need for external components to fix the position of the adjusting arm, resulting in a simple structure.

[0047] Specifically, during adjustment, the threaded drive 111 can be manually rotated. Under the constraint of the threaded connection between the two, the rotational motion of the threaded drive 111 can be switched to the linear motion of the slide 120 along the first direction, and the adjustment arm 220 can be driven to move linearly along the second direction via the drive arm 210. The direction of movement of the adjustment arm 220 can be changed by controlling the rotation direction of the threaded drive 111, making the operation simple.

[0048] The threaded connection length between the threaded drive 111 and the slide 120 can be set according to actual needs, provided that the following two conditions are met: First, when the threaded drive 111 is screwed into the slide 120 at its limit position, it ensures that both adjusting arms 220 extend to the outside of the corresponding side wall of the refrigerator and abut against the corresponding side wall of the kitchen cabinet 600. Second, when the threaded drive 111 is at its limit position unscrewed from the slide 120, it ensures that both adjusting arms 220 are located inside the corresponding side wall of the refrigerator, so as not to hinder transportation or transfer operations.

[0049] See Figures 2 to 4 As shown, according to some embodiments of the present invention, the drive assembly 110 further includes a fixed base 112, one end of the threaded drive member 111 is connected to the fixed base 112, and the fixed base 112 is configured to be fixedly connected to the refrigerator body 500.

[0050] By setting the fixed seat 112, one end of the threaded drive 111 can be fixedly connected to the refrigerator body 500, ensuring that the threaded drive 111 can stably drive the slide 120 to move in the first direction when it rotates.

[0051] Specifically, the fixed base 112 serves to provide a stable support point, ensuring that the threaded drive 111 does not shift or wobble during rotation. In this way, the threaded drive 111 can effectively drive the slide 120 to move along the first direction through the motion generated by rotation, maintaining the stability of the entire centering structure during adjustment.

[0052] It should be noted that one end of the thread drive 111 is movably connected to the fixed base 112, which ensures that the thread drive 111 can rotate along its own axis under the action of external force.

[0053] See Figures 2 to 4 As shown, according to some embodiments of the present invention, the fixed base 112 is provided with a first limiting groove 113, at least a portion of the threaded drive member 111 cooperates with the first limiting groove 113, and the first limiting groove 113 is used to limit the degree of freedom of the threaded drive member 111 along the second direction.

[0054] By providing a first limiting groove 113 on the fixed base 112 to restrict the degree of freedom of the thread drive 111 along the second direction, the stability of rotating the thread drive 111 can be improved, preventing the thread drive 111 from swinging along the second direction. At the same time, the first limiting groove 113 can also serve as a guide, ensuring that the thread drive 111 always moves along the first direction when rotating, thus ensuring the smoothness and stability of the adjustment operation.

[0055] Specifically, when the thread drive 111 is manually rotated, a certain lateral force is usually generated. Without effective restraint, the thread drive 111 may swing or deviate in the second direction, thereby affecting its smoothness and stability.

[0056] See Figures 2 to 4 As shown, according to some embodiments of the present invention, one end of the threaded drive member 111 is provided with a joint portion 114, and the side wall of the fixed seat 112 facing the joint portion 114 is provided with a clearance opening 115.

[0057] By providing a joint 114 at one end of the thread drive 111 and a clearance opening 115 on the side wall of the fixed seat 112 facing the joint 114, it is easy to manually operate the thread drive 111 to rotate, thus improving the convenience of centering structure adjustment.

[0058] Specifically, during adjustment, a tool can be inserted through the clearance port 115 to the location of the engagement portion 114, thereby connecting with the engagement portion 114 of the thread drive member 111. The user can use the tool to directly act on the engagement portion 114 and achieve the adjustment purpose by rotating the thread drive member 111. The design of the clearance port 115 ensures that the tool can smoothly enter and mate with the engagement portion 114.

[0059] As an example, the joint 114 in this embodiment is a slotted or Phillips head slot, which can be directly driven to rotate the threaded drive 111 by a screwdriver.

[0060] See Figure 1 and Figure 5 As shown, according to some embodiments of the present invention, the second end of the adjusting arm 220 is provided with a guide wheel 230.

[0061] By setting a guide wheel 230 at the second end of the adjusting arm 220, when the adjusting arm 220 extends to the predetermined position, the guide wheel 230 can contact the side wall of the kitchen cabinet 600. Thus, when the refrigerator is pushed in, the sliding friction between the adjusting arm 220 and the side wall of the kitchen cabinet 600 can be converted into rolling friction, which can help the refrigerator enter the kitchen cabinet 600 smoothly.

[0062] According to some embodiments of the present invention, the guide wheel 230 is a flexible guide wheel 230.

[0063] By setting the guide wheel 230 as a flexible guide wheel 230, the adaptability of the adjusting arm 220 and the stability of the refrigerator when it is pushed into the kitchen cabinet 600 can be further improved.

[0064] Specifically, the flexible guide roller 230 has a certain degree of elasticity and deformability, which can better adapt to the slight unevenness or changes on the side wall of the kitchen cabinet 600, making the process of pushing the refrigerator in more stable. In addition, the flexible guide roller 230 can provide a cushioning effect when it comes into contact with the side wall of the kitchen cabinet 600, reducing hard impact and friction, and reducing damage to the refrigerator and the kitchen cabinet 600.

[0065] The flexible guide wheel 230 can be made of a variety of materials known in the prior art, such as rubber, silicone, polyurethane (PU), etc.

[0066] See Figure 1 As shown, according to some embodiments of the present invention, the centering structure further includes a first limiting member 300, which is configured to be fixedly connected to the refrigerator body 500. A second limiting groove is formed on the first limiting member 300, and the slide 120 is located in the second limiting groove to limit the slide 120 to move along the first direction. It also includes a second limiting member 400, which is configured to be fixedly connected to the refrigerator body 500. A third limiting groove is formed on the second limiting member 400, and the adjusting arm 220 is located in the third limiting groove to limit the adjusting arm 220 to move along the second direction.

[0067] By setting the first limiting member 300 and the second limiting member 400, the slide 120 and the adjusting arm 220 can be limited respectively, so that when the centering structure is adjusted, the slide 120 can always move along the first direction and the adjusting arm 220 can always move along the second direction, ensuring the reliability and stability of the centering structure during adjustment, and preventing the slide 120 and the adjusting arm 220 from shifting during adjustment, which would affect the centering accuracy of the centering structure.

[0068] Specifically, both the first limiting member 300 and the second limiting member 400 are detachably connected to the refrigerator body 500. Both the first limiting member 300 and the second limiting member 400 are fastened to the refrigerator body 500 and secured with threaded fasteners. There is at least one first limiting member 300 and at least one second limiting member 400, and the specific number can be determined based on the length of the slide block 120 and the adjusting arm 220; there is no limitation on this.

[0069] See Figure 3 As shown, according to some embodiments of the present invention, the slide block 120 is provided with a receiving groove 121 at one end near the drive arm 210, and the first end of the drive arm 210 is located in the receiving groove 121.

[0070] By providing a receiving groove 121 at one end of the slide block 120 near the drive arm 210 and placing the first end of the drive arm 210 inside the receiving groove 121, the overall length of the centering structure along the first direction can be reduced, thereby improving the compactness of the centering structure.

[0071] Specifically, the receiving groove 121 is provided with a hinge post, and the first ends of the two drive arms 210 are hinged to one end of the slide block 120 through the hinge post.

[0072] See Figure 1 As shown, according to some embodiments of the present invention, the first direction and the second direction are perpendicular to each other.

[0073] By configuring the first direction and the second direction to be perpendicular to each other (i.e., the sliding direction of the slide block 120 is perpendicular to the moving direction of the adjusting arm 220), the response speed during the adjustment of the centering structure can be improved, and the centering adjustment can be made faster and more accurate.

[0074] Specifically, when the slide 120 and the adjusting arm 220 are perpendicular to each other, that is, when the slide 120 is set in the depth direction of the refrigerator and the adjusting arm 220 is set in the width direction of the refrigerator, when the driving component 110 drives the slide 120 to move in the first direction, it can drive the adjusting arm 220 to move completely in the width direction of the refrigerator without having a velocity component in the depth direction of the refrigerator, thereby improving the response speed when adjusting the centering structure and achieving faster and more accurate centering adjustment.

[0075] The refrigerator provided by this utility model is described below. The refrigerator described below can be referred to in correspondence with the centering structure described above.

[0076] See Figure 6 and Figure 7 As shown, the refrigerator provided in this embodiment of the present invention includes: a cabinet 500 and a centering structure as described in any of the above embodiments, a slide block 120 being slidably connected to the cabinet 500 along a first direction, and an adjusting arm 220 being slidably connected to the cabinet 500 along a second direction.

[0077] The refrigerator provided by this utility model adopts the aforementioned centering structure, thus ensuring that the refrigerator accurately centers itself upon entering the kitchen cabinet 600 during the pushing process. Because the adjusting arm 220 applies very little pressure to the kitchen cabinet 600, it will not cause damage to the cabinet during the pushing process. Simultaneously, the refrigerator will not rub against the side wall of the kitchen cabinet 600 during pushing, and no further adjustments are required after the refrigerator is fully inside the cabinet 600, thereby improving the stability of the refrigerator within the cabinet 600.

[0078] See Figure 6 As shown, according to some embodiments of the present invention, the centering structure is located at the bottom of the box 500.

[0079] By placing the centering structure at the bottom of the cabinet 500, the centering structure can be avoided from occupying the top or side space of the cabinet 500, making the refrigerator design more compact and the overall space utilization more reasonable.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
