Detailed Description

As background art, there are many irrational in the design of existing stiffeners for household appliances.

Taking a refrigerator as an example, a typical installation method of a reinforcement component is as follows: the plastic stud hole is directly formed in the plastic part in an injection molding mode, and the self-tapping screw penetrates through the bearing part (such as the guide rail) and the liner through hole to achieve the effects of locking and strengthening the bearing capacity of the guide rail. The reinforcement component has the advantages of low cost and difficult generation of condensation in the refrigerator. However, the plastic stud has the defects that the screw slipping phenomenon is easily generated in the screw locking process, the plastic screw can be locked and attached for three times, and the plastic reinforcing piece cannot be repeatedly disassembled when a customer needs to replace the guide rail.

Another typical installation method is to use a metal reinforcement assembly, specifically, the metal post is threaded and locked with a machine screw. The advantages of this type of stiffener assembly are: the metal thread can be repeatedly disassembled. However, the overall cost is relatively high, and the metal reinforcement is likely to cause a condensation phenomenon inside the refrigerator.

In summary, the existing reinforcing member for the refrigerator compartment cannot meet the user requirements of low cost, no condensation, detachability and the like.

To solve the above technical problem, an embodiment of the present invention provides a reinforcement assembly for a home appliance, including: a body portion made of plastic; a metal fixing member fixed to the main body portion, the metal fixing member having a threaded hole; wherein the main body portion is exposed out of the threaded hole.

The technical personnel in the field understand, this embodiment reinforcement subassembly adopts the mounting means of the metal mounting of fixed band screw hole in the plastics main part, and whole structure metal content is few, does benefit to the whole weight that alleviates the reinforcement subassembly, and the metal mounting that is used for playing the fixed effect of enhancement can be shaping through the punching press, and cost efficiency is higher.

Furthermore, as the threaded holes are made of metal materials, the thread is not easy to slip in the use process, so that the whole reinforcement component can be repeatedly disassembled, and the service life of the reinforcement component is prolonged. Furthermore, because the body of the stiffener assembly is made of plastic, this is advantageous in reducing the likelihood of condensation, and the body of plastic is easier to form into a variety of different configurations, so that the designer may have greater freedom in designing the stiffener assembly.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

FIG. 1 is a schematic view of a main body portion of a stiffener assembly according to an embodiment of the present invention. Wherein, the reinforcement subassembly of this embodiment can be applied to refrigeration plant such as refrigerator, freezer, also can be applied to the domestic appliance that needs the bearing strength of reinforcing bearing member such as wardrobe, dish washer.

Specifically, in the present embodiment, in conjunction with fig. 1 and 2, the stiffener assembly 100 may include: a body portion 110 made of plastic; a metal fixing member 120 fixed to the body portion 110, the metal fixing member 120 having a screw hole 121; the body 110 exposes the screw hole 121.

Therefore, by adopting the installation mode of the metal fixing piece 120 with the fixing threaded hole 121 in the main body part 110 made of plastic, the metal content of the whole structure of the reinforcing piece assembly 100 is low, the whole weight of the reinforcing piece assembly 100 is favorably reduced, the metal fixing piece 120 used for reinforcing and fixing can be formed by stamping, and the cost efficiency is higher.

Further, as the threaded hole 121 is made of a metal material, the thread is not easy to slip in the using process, so that the whole reinforcing member assembly 100 can be repeatedly disassembled, and the service life of the reinforcing member assembly 100 is prolonged. Furthermore, since the main body (i.e., the main body portion 110) of the reinforcement assembly 100 is made of plastic, it is advantageous to reduce the possibility of dew condensation, and the main body portion 110 made of plastic is more easily formed into various different configurations, so that the designer can have a greater degree of freedom in designing the reinforcement assembly 100.

In one or more embodiments, the metal fixing member 120 is detachably fixed to the body part 110. Therefore, partial part replacement of the reinforcement member assembly 100 can be realized, for example, in the manufacturing process and/or the after-sale process, especially for parts such as the metal fixing member 120 which are vulnerable to damage due to frequent locking, the solution of the embodiment allows the metal fixing member 120 to be detached and replaced independently without removing the whole reinforcement member assembly 100, thereby greatly reducing the replacement cost of the reinforcement member assembly 100 and being beneficial to prolonging the service life of the whole structure of the reinforcement member assembly 100.

In one or more embodiments, the metal fixing member 120 may be fixed inside the main body portion 110, and for a scene used in a refrigeration device such as a refrigerator, direct contact between the metal fixing member 120 and a region where condensation is likely to occur may be significantly reduced, so that the probability of condensation caused by the reinforcement assembly 100 may be effectively reduced.

In one or more embodiments, referring to fig. 3, the body part 110 may include a receiving cavity 111 and a cover part 112 adapted to close the receiving cavity 111, the receiving cavity 111 is adapted to receive a metal fixing member 120, and the receiving cavity 111 has a threaded through hole 113 adapted to a threaded hole 121. Therefore, the metal fixing piece 120 can be firmly fixed in the main body part 110 through the matching of the accommodating cavity 111 and the cover part 112, the threaded hole 121 in the metal fixing piece 120 can be always aligned with the threaded through hole 113 in the accommodating cavity 111, and the reinforcement component 100 can be conveniently installed on the household appliance.

For example, the threaded through hole 113 may be opened at the bottom surface 111b of the receiving cavity 111 and extend to a surface of the body part 110 close to the home appliance when being mounted to the home appliance.

In a typical application scenario, when the reinforcement assembly 100 is mounted on the sidewall of the household appliance, the screw sequentially passes through the through hole of the load-bearing member and the through hole of the household appliance, and then extends into the threaded through hole 113 and couples with the threaded hole 121, so as to firmly screw the load-bearing member and the reinforcement assembly 100.

In one or more embodiments, the metal fixing member 120 may be adhesively received in the receiving cavity 111 to prevent the threaded hole 121 and the threaded through hole 113 from being misaligned due to an unexpected movement of the metal fixing member 120 in the receiving cavity 111.

In one or more embodiments, referring to fig. 1 to 3, the shape of the receiving cavity 111 may be adapted to the shape of the metal fixing member 120. Therefore, the metal fixing member 120 can be better fitted with the accommodating cavity 111, so as to fix the metal fixing member 120 in the main body portion 110 more accurately.

For example, the metal fixing member 120 may be received in the receiving cavity 111 in an interference fit manner to increase a friction force between an outer edge of the metal fixing member 120 and an inner edge of the receiving cavity 111, which may also avoid the threaded hole 121 and the threaded via 113 from being misaligned due to an unexpected movement of the metal fixing member 120 in the receiving cavity 111.

Specifically, the shapes of the metal fixing member 120 and the receiving cavity 111 may be triangular, rectangular, polygonal, cross-shaped (as shown in fig. 1 to 3), irregular, and the like.

In one or more embodiments, the metal fixing member 120 may have at least one positioning angle 122, and for each positioning angle 122, the receiving cavity 111 has a positioning angle receiving portion 114 adapted to perform a left-right positioning function to prevent the metal fixing member 120 from rotating unexpectedly in the receiving cavity 111. Here, left and right indicate ± x directions (and/or ± y directions) in the drawing.

In a typical application scenario, during the process of coupling with the screw, the positioning angle 122 and the positioning angle receiving portion 114 cooperate to effectively prevent the metal fixing member 120 from rotating along with the rotation of the screw.

In one or more embodiments, the plurality of positioning angles 122 may be uniformly and symmetrically distributed on the metal fixing member 120, and similarly, the corresponding plurality of positioning angle receiving portions 114 may also be uniformly and symmetrically distributed on the receiving cavity 111.

For example, referring to fig. 1 to 3, the number of the positioning angles 122 and the corresponding positioning angle receiving portions 114 may be 4 and are uniformly and symmetrically distributed on the metal fixing member 120 and the receiving cavity 111.

In one or more alternative examples, the plurality of positioning angles 122 may also be distributed unevenly and asymmetrically on the metal fixing member 120, and similarly, the corresponding plurality of positioning angle receiving portions 114 may also be distributed unevenly and asymmetrically on the receiving cavity 111.

In one or more embodiments, referring to fig. 1-6, the positioning angle 122 may extend outward from the sidewall 120a of the metal fixture 120 and be in the same plane as the upper surface 120b (and/or the lower surface 120c) of the metal fixture 120. Similarly, the corresponding positioning corner receiving portion 114 may also extend outward from the sidewall 111a of the receiving cavity 111 and be in the same plane with the bottom surface 111b of the receiving cavity 111.

In one or more alternative examples, referring to fig. 7, assuming that the upper surface 120b of the metal fixing member 120 is the side close to the bottom surface of the accommodating cavity 111, the positioning angle 122 may be recessed from the upper surface 120b in the direction of the lower surface 120c and protrude outward from the lower surface 120c (i.e., protruding in the + z direction as shown). Similarly, the corresponding positioning angle receiving portion 114 may protrude from the bottom surface 111b in the + z direction as shown. Therefore, when the metal fixing element 120 is placed in the accommodating cavity 111, the positioning angle 122 and the positioning angle accommodating part 114 can also play a role of limiting.

In one or more embodiments, referring to fig. 4 to 6, the portion of the metal fixture 120 with the positioning angle 122, except for the positioning angle 122, may have a circular arc shape (or a shape with a circular arc shape and a straight line with a transition interval). Further, the positioning corner 122 may have various shapes such as triangle, rectangle, polygon, etc.

Further, the number of the positioning angles 122 may be 1 or more.

Similarly, the shape of the receiving cavity 122 may be determined according to the shape of the metal fixture 120.

In one or more embodiments, the threaded hole 121 may be located at the geometric center, or the center of gravity, of the metal fixture 120, or other suitable locations that are not prone to fracture of the metal fixture 120. The position of the threaded through hole 113 opened in the receiving cavity 111 may be determined according to the position of the threaded hole 121 on the metal fixture 120.

In one or more embodiments, the number of threaded holes 121 may be one (as shown in fig. 2, 4, 5, and 7), two (as shown in fig. 6), or even more. The number of the threaded through holes 113 opened in the receiving cavity 111 corresponds to the number of the threaded holes 121.

In one or more embodiments, referring to fig. 8, when the cover part 112 closes the accommodating cavity 111, the inner surface 112a of the cover part 112 abuts against the metal fixing member 120 to achieve the up-and-down positioning effect through the cover part 112, so as to prevent the metal fixing member 120 from undesirably shaking in the accommodating cavity 111. Wherein, the upper and lower are indicated in the ± z direction of the figure. That is, the inner surface 112a of the cover part 112 is engaged with the angular positioning receiving part 114, so that the metal fixture 120 can be prevented from moving in the receiving cavity 111 in all directions in the ± z direction, the ± y direction, and the ± x direction, and the metal fixture 120 can be firmly fixed to the body part 110.

In one or more alternative examples, referring to fig. 9, the cover part 112 may have a groove 115 adapted to the accommodating cavity 111, when the cover part 112 closes the accommodating cavity 111, a bottom surface 115a of the groove 115 abuts against the metal fixing member 120, so as to achieve an up-and-down positioning effect through the cooperation of the groove 115 and the accommodating cavity 111, and prevent the metal fixing member 120 from generating unexpected shaking in the accommodating cavity 111. Accordingly, the bottom surface 115a of the recess 115 formed in the cover 112 is fitted into the angular positioning receiving portion 114, whereby the metal fixture 120 can be prevented from moving in the receiving cavity 111 in all directions in the ± z direction, the ± y direction, and the ± x direction, and the metal fixture 120 can be firmly fixed to the body 110.

In one or more alternative examples, referring to fig. 1 and fig. 3, the cover portion 112 may have a supporting portion 116, and when the cover portion 112 closes the accommodating cavity 111, the supporting portion 116 is supported against the metal fixing member 120, so as to achieve the vertical positioning function through the supporting portion 116, and prevent the metal fixing member 120 from undesirably shaking in the accommodating cavity 111.

Specifically, the shape of the abutting portion 116 may be adapted to the shape of the metal fixing element 120, as shown in fig. 1 to 3, so as to abut against the metal fixing element 120 in all directions.

Alternatively, the abutting portion 116 may be a cylinder with any shape protruding from the inner surface 112a of the cover portion 112 to the direction of the accommodating cavity 111, so as to reduce the complexity of the manufacturing process.

In one or more embodiments, referring to fig. 1 and 3, the body portion 110 can include a base portion 117 provided with the receiving cavity 111, and the cover portion 112 can be flexibly coupled to the base portion 117. Therefore, when the cover part 112 opens the accommodating cavity 111, the cover part 112 is still connected with the base part 117 and cannot be completely separated from the main body part 110, the operation of a user is convenient, and the situation that the accommodating cavity 111 cannot be closed due to the loss of the cover part 112 is avoided.

Specifically, the receiving cavity 111 is disposed at one side of the base 1117 facing the cover 112, and one end of the threaded through hole 113 extends to the opposite side of the base 1117 to be able to couple with a screw passing through the home appliance when mounted to the home appliance.

Further, the cover 112 and the base 117 may be connected by a flexible foldable bridge 118.

In a typical application scenario, after the metal fixing member 120 is placed in the receiving cavity 111 of the main body 110 shown in fig. 1, the cover portion 112 is turned over to the position shown in fig. 10. At this time, the inner surface 112a of the lid 112 (or the bottom surface 115a of the groove 115 formed on the lid 112, or the abutting portion 116 provided on the lid 112) presses the metal fixing member 120, thereby achieving an effect of fixing the metal fixing member 120 in the body 110. Moreover, the cover part 112 and the receiving cavity 111 cover most regions of the metal fixture 120 except for the screw hole 121, thereby preventing the metal fixture 120 from being directly exposed.

In one or more embodiments, the base 117 and the cover 112 can be snap-fit at least one end of the receiving cavity 111. Thus, when the cover part 112 closes the accommodation cavity 111 (as shown in fig. 10), the cover part 112 is snap-coupled with the base part 117 to hold the cover part 112 in a state of closing the accommodation cavity 111, so as to fix the metal fixture 120 in the accommodation cavity 111.

In an alternative, referring to fig. 3, the base 117 has opposite first and

second ends

117a, 117b, the cover 112 has opposite first and

second ends

112b, 112c, and the first end 117a of the base 117 is flexibly coupled to the first end 112b of the cover 112.

For example, the first end 117a of the base 117 and the first end 112b of the cover 112 may be connected by a flexible foldable bridge 118. In contrast, the second end 117b of the base 117 and the second end 112c of the cover 112 may contact or separate from each other to enable the cover 112 to open or close the receiving cavity 111.

In an alternative example, the first end 117a of the base 117 may have a first latch 130, and the first end 112b of the cover 112 may have a first coupling portion 131, such that when the first latch 130 is coupled with the first coupling portion 131, the cover 112 closes the receiving cavity 111.

In an alternative example, the second end 117b of the base 117 may have a second latch 132, and the second end 112c of the cover 112 may have a second coupling portion 133, so that when the second latch 132 is coupled with the second coupling portion 133, the cover 112 closes the receiving cavity 111.

Thus, the cover 112 can be securely attached to the base 117 by the engagement of the first engaging portion 130 with the first coupling portion 131 and/or the engagement of the second engaging portion 132 with the second coupling portion 133, so that the cover 112 can be held in a position closing the accommodation chamber 111.

In one or more alternative examples, the cover portion 112 is just sized to close the accommodating cavity 111, and the first locking portion 130 and/or the second locking portion 132 may be respectively disposed at two ends of the accommodating cavity 111 along the ± x direction, which may also achieve the effect of closing the accommodating cavity 111 by the cover portion 112.

In one or more embodiments, referring to fig. 1, at least one metal fastener 120 may be disposed at each end of the main body 110 along the length direction (i.e., the ± x direction) to distribute the load-bearing force and optimize the load-bearing capacity of the stiffener assembly 100. Accordingly, each of the metal fasteners 120 is fixed in a corresponding one of the body portions 110.

Specifically, the plurality of metal fasteners 120 may be arranged in ± x and/or ± y directions at both ends of the body part 110.

Alternatively, two or more metal fixing members 120 may be disposed in one main body portion 110, wherein a plurality of accommodating cavities 111 are disposed on the main body portion 110, and each metal fixing member 120 is disposed in a corresponding accommodating cavity 111. Specifically, the plurality of receiving cavities 111 may be arranged in ± x and/or ± y directions within the body portion 110.

In one or more embodiments, the main body 110 may have a through hole 134 formed between the two metal fasteners 120, which is convenient for taking during installation and is also beneficial for improving the overall aesthetic appearance of the reinforcement assembly 100.
