Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Following instance
For illustrating the present invention, but it is not intended to limit the scope of the invention.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can
To be mechanical connection, it is also possible to be electrically connected；It can be directly connected, can also can be indirectly connected through an intermediary
Connection inside two elements.
In order to solve after refrigerator doors end cap sidewalls are thinning in the prior art, the reinforcing rib of door cover internal is easy in door end cap
Outer surface the problem of forming indent (shrink).The present invention provides a kind of refrigerator thin-walled door end cap and refrigerator.
Next, this technology will be described in detail by basic engineering, extension design and alternative design:
A kind of refrigerator thin-walled door end cap, such as Fig. 4,5, long reinforcing rib 4, Men Duan of the inside setting along door end cap length direction
Arch surface is arranged in the long reinforcing rib 4 of correspondence and the position of the intersection point of door rubbing surface of end cover in exterior surface；Long reinforcing rib 4 and adjacent surface
Short reinforcing rib is not provided between 6.
Referring herein to along door end cap length direction, it is intended that in conjunction with the different in width of refrigerator, the length of door end cap determines therewith,
Substantially equal with the width of refrigerator.In this end cap length, the long raising of reinforcing rib 4 is arranged in the stress of length direction in inner sidewall
Intensity, under normal conditions long reinforcing rib 4 be positioned close to an end cap upper side wall, lower wall two positions on, can be parallel to
Door end cap top edge, can also keep inclination slightly.Trend regardless of long reinforcing rib 4, arch surface are all set to an end
Exterior surface corresponds to the position of long reinforcing rib 4 and door end cap tie point.
Since shrink phenomenon is present in an external face, and in the corresponding position for connecting long and short reinforcing rib, i.e., due to
The tensile stress of long and short reinforcing rib leads to an external face recess, pair for the situation, in the position for connecting long reinforcing rib 4
Should place be made into arch surface, alleviated using the mechanical characteristic and deformation behavior of arcuate structure, the stress of reinforced door end cap sidewalls it is strong
Degree.
Next arch surface is stated:
The first situation, arch surface include: the first cambered surface, the lateral surface of the first cambered surface and the side wall that long reinforcing rib 4 is arranged
5 is tangent.
Arch surface under in view of the situation, as shown in figure 5, first cambered surface can be Chamfering fillet surface, with long reinforcing rib 4
It is parallel to for an end cap lower edges, the set-up mode of Chamfering fillet surface are as follows:
Step 110, the median plane of long reinforcing rib 4 is determined；
It is profilograph shown in figure.The median plane is rendered as straight line.
Step 120, it determines median plane and the intersection C of the lateral surface 5 of the side wall of long reinforcing rib 4 is set；
This step purpose is to determine traction action point of the link position of long reinforcing rib 4 on the outer surface of door end face.?
A point of intersection C is only seen in Fig. 5.
During finding intersection, if it can be plane (vertical plane for crossing vertical line) with original lateral surface 5.Intersection C
Not in the arch surface really formed.
Step 130, the ray plane BC of intersection C, the lateral surface of ray plane and the side wall that long reinforcing rib 4 is set were constructed
5 angle is β；
Ray plane and with each point on intersection for initial point, plane that all rays are formed.In addition, angle β is can be with
According to the traction force of long reinforcing rib 4 get up specifically determine.It is preferred that angle meets: 15 °≤β≤30 °.It needs to illustrate herein
It is the arch surface in order to form evagination, ray plane must be directed towards an end cap, as shown in the figure, and obliquely towards a left side, make to penetrate
Line plane and 5 place vertical line angle of lateral surface are β.
Step 140, in the outside for the side wall that long reinforcing rib 4 is arranged, building ray plane BC and the long reinforcing rib 4 of setting
The Chamfering fillet surface of 5 angle of lateral surface of side wall.
Ray plane BC and 5 angle of lateral surface that the side wall of long reinforcing rib 4 is arranged are angle β on Fig. 5.
The Chamfering fillet surface and ray plane BC are tangent with straight line B, are rendered as a little in Fig. 5.Chamfering fillet surface is tangent with side surface
It is rendered as a little in straight line D, Fig. 5.
It should be noted that Chamfering fillet surface, which can extend to an end cap roof, (is arranged the outer of the side wall of long reinforcing rib 4
The adjacent surface 6 of side 5.
Second situation: arch surface further include: the second cambered surface, the second cambered surface be Chamfering fillet surface and 5 adjacent surface 6 of lateral surface it
Between transition cambered surface.
I.e. arch surface is formed by connecting by the first cambered surface, the second cambered surface.
In some embodiments, it is possible to understand that the second cambered surface is in order to promote product appearance more beautiful, close to adjacent surface 6
Position done conventional corner processing.Second cambered surface with
The third situation: the second cambered surface in second situation is made between 5 adjacent surface 6 of ray plane BC and lateral surface
Transition cambered surface.
In this case, the second cambered surface and ray plane are tangent in straight line A；Second cambered surface intersects with adjacent surface 6.Straight line and
Straight line B constitutes the first plane；Arch surface includes: sequentially connected first cambered surface, the first plane, the second cambered surface.
The present invention also provides a kind of refrigerators comprising refrigerator main body and refrigerator thin-walled door end cap, refrigerator thin-walled door end cap
It is mounted on upper end, the lower end of refrigerator door opening.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
