Embodiment
Below in conjunction with Figure of description, the utility model is further described.
The utility model base, the special-shaped base that it is interconnected to constitute by some supporting frames end, support frame as described above comprises the plastic casing that Steel Support is outer with being wrapped in described Steel Support, and the junction surface of described Steel Support and described plastic casing is the curved bend folded structure.
The utility model LCD TVs, at least comprise liquid crystal disply device and the base that supports described liquid crystal disply device, and described base is above-mentioned base.
As shown in Figures 1 to 4, the present embodiment base, for being applied to the base of large scale liquid crystal TV, described base 1 is connected and is formed by two supporting frame ends, support frame as described above comprises Steel Support 14 and is wrapped in the outer plastic casing 13 of described Steel Support, two metal supporting frames are the first supporting frame 11 and the second supporting frame 12, described the first supporting frame and described the second supporting frame axisymmetric arrange the formation herringbone structure, the length of the base of described herringbone structure on the x axle direction is 60mm, length on the y axle direction is 28mm, the thickness of described plastic casing is 4mm, angle α between the first supporting frame and the second supporting frame is 60 °.Described the first supporting frame and described the second supporting frame are arcuate structure, the joint of described the first supporting frame and described the second supporting frame is provided with two supporting bases, described the first supporting frame and described the second supporting frame end separately are respectively equipped with a supporting base, form four supporting bases and contact with the support platform that supports described support, four supporting bases are provided with bath mat.
The present embodiment base, described supporting frame is by carrying out plastic injection-moulded processing at metal support surface, with base of the prior art, compare, base set in the present embodiment base and the simple Steel Support advantage separately of simple plastic material, the embedded structure that Steel Support and plastic casing are formed in one simultaneously, integrated understructure has reduced the installation step of Steel Support and plastic casing on the one hand, has reduced workman's workload; With Steel Support and the plastic casing of existing assembly structure, need to accomplish fully suitable on the other hand, also needing the designer to set up rational model compares, integrated base has reduced the time that the designer sets up model, shortened the construction cycle, and the base of this structure ratio is easier to realize batch production, so minimizing effectively the cost of base.Steel Support is wrapped in and Steel Support is carried out plastic injection-mouldedly in plastic casing, can reduce the infringement of external environment condition to metal, extend the working life of metallic material as the parts of weighing.
The supporting frame of the base in the present embodiment, because be, for the large scale display unit, design, want to meet described large scale display unit is carried out to stable support, the size of supporting frame being had to certain requirement is also that length on the x direction of base is at least 45mm, be at least 23mm on the y direction, the thickness of plastic casing is no less than 2mm.In order to meet this size requirement, in the present embodiment, to be respectively the length on the x axle direction be 60mm to the size of base, and the length on the y axle direction is 28mm, and the thickness of described plastic casing is 4mm.Because the size of supporting frame described in the present embodiment is larger, the insert structure of large-sized metal and plastics is in the temperature gradient change procedure, expansion coefficient difference due to bi-material, junction surface at bi-material can produce certain shearing force, particularly in curvature, change more violent position, can cause local stress to concentrate, probably cause link position cracking, the plastic casing of plastic casing and metal to turn white, the problems such as outward appearance damage of plastic casing.In order to avoid as much as possible the appearance of these problems, supporting frame described in this enforcement embodiment adopts arcuate structure, be also to adopt arc-shaped transition between the junction surface of plastic casing and Steel Support, the one, the infringement problem of the supporting frame of having avoided as much as possible the expansion coefficient difference due to two kinds of materials to cause.The 2nd, arcuate structure can reduce the resistance in injection moulding process, avoids the stress of partial structurtes to concentrate.
The first supporting frame and second supporting frame of the base in the present embodiment are structure as a whole, and the operation of assembling has been saved in the design of integrative-structure, and the rigidity of Integral design supporting base is better.Be provided with two supporting bases at the first supporting frame and the interconnective position of the second supporting frame in the present embodiment, using simultaneously the first supporting frame and the second supporting frame separately not interconnective end respectively as a supporting base, the curved unsettled setting in the middle part of supporting frame, base contacts with the supporting surface that supports described base by four force bearing points, 4 structures that end is stressed, bottom surface and the contacted design of supporting surface of seat in the contrast prior art, base in the present embodiment is when supporting display unit, the design of unsettled arcuate structure can be optimized the overall dimensions of base to greatest extent, under equal conditions, material saving, in the overall structure rigidity, under certain prerequisite, force bearing point is distributed in end, can suitably increase pliability, lowers the frequency of structure, avoids causing resonance phenomenon at low frequency, the hanging structure of arc, when the load-bearing of base increases, the arc hanging structure of the first supporting frame and the second supporting frame can provide a cushion effect, avoids the damage to supporting frame.
Base in the present embodiment adopts the herringbone structure of symplex structure, and herringbone structure is simple, and injection moulding is convenient, in the joint of the first supporting frame and the second supporting frame, two supporting bases are set, end arranges two supporting bases, the leg-of-mutton supporting structure of class, good stability.For the weight that alleviates as much as possible base and the fabricating cost of base, metal supporting frames described in the present embodiment adopts sheet structure, and the bottom surface yet contacted with the supporting surface of base for supporting in the non-appearance of metal supporting frames is not wrapped in plastic casing.Span for the angle α of the first supporting frame of man type base and the second supporting frame is 60 °≤α≤135 °, and the present embodiment consideration has as the case may be been chosen 60 °.
