Abstract
An integrated latch (104) for a battery cover (102) of a cellular telephone (100) that combines the high yield and fatigue characteristics of metal with the desired appearance and feel aesthetics of plastic. The latch (104) includes a metal spring (400) that is overmolded with plastic to increase the strength and durability of the latch.
Description
The present invention relates generally to blocking mechanism.Although the present invention is with a wide range of applications, only be described by cell phone.
The cellular housing of GSM Star TACTM of Motorola Inc. is made by polycarbonate plastic.For the reason of aesthetic aspect, the detachable battery of phone lid is also made with identical polycarbonate plastic.Integrated molding locking member is locked in battery on the phone on the battery cover.This locking member is also made by polycarbonate plastic.In this field, proved that locking member (promptly unblanking and locking) after using some cycles can lose efficacy, this periodicity is less than the periodicity of expectation far away.Finite element analysis proof locking member is designed to the yield strength (point of material generation permanent deformation) that Merlon has exceeded it.Cause shorten fatigue life, limited the periodicity that lost efficacy greatly.
Locking member lost efficacy and causes phone to be returned maintenance.Lost efficacy for fear of locking member, and the material of battery cover and locking member is changed be polyphenylene oxide (PPO) plastics of " general electronic corporation " board, and be also referred to as the NorylTM plastics, it is more pliable and tougher and can make locking member withstand the more cycle.Yet the outward appearance that NorylTM plastic battery lid is dim and the polycarbonate plastic of cell phone body are not in tune, make this product be difficult to attract the user.
In locking member mechanism, use metal to strengthen the intensity of locking member.Comprise in the cellular suspension cover of the ZAPTM of Motorola Inc. and have the metal locking member that embeds the molding button.For the reason of aesthetics, part is exposed to outer clip electroplates.Because metal locking member plastics of no use carry out outer molded (overmolded), therefore phone is being put into and when hanging cover and taking out, the metal locking member scratches phone easily.
The cellular battery of Micro TACTM of Motorola Inc. has used the metal spring that is assemblied on the plastics locking member, is used to increase the intensity of locking member.Must spring be inserted on the locking member with hand.This method needs a large amount of labours, and has increased manufacturing cost.
Need a kind of locking member that is integrated on the battery cover, the inefficacy that it uses polycarbonate plastic and can reduce locking member.
Fig. 1 is a kind of cellular stereogram that can use integrated fastener preferred embodiment of the present invention.
Fig. 2 is the stereogram of first preferred embodiment of battery cover among Fig. 1.
Fig. 3 is the stereogram of second preferred embodiment of battery cover among Fig. 1.
Fig. 4 is Fig. 2, the stereogram of locking member spring in 3.
Fig. 5 is the profile of the integrated fastener of the present invention of 5-5 interceptings of the line on the battery cover in Fig. 3.
The invention provides a kind of battery cover that is used on the radio telephone, wherein the integrated fastener on the battery cover comprises a metal spring clip that carries out outer molded with plastics.Other advantage of the present invention and novel characteristic will partly be set forth in the following description, wherein show and have described the preferred embodiments of the present invention.Describe in detail according to embodiments of the invention below.
Integrated fastener of the present invention combines the height surrender of metal and the desirable appearance and the aesthetic feeling of fatigue properties and plastics.Fig. 1 has showed the radio telephone 100 that has detachable battery lid 102, and battery cover 102 has used locking member 104 of the present invention.As shown in Figure 1, battery cover 102 is arranged in the lid 106 of radio telephone 100.Fig. 2 has showed the stereogram of the battery cover 102 after taking off from radio telephone 100.In first embodiment, battery cover 102 comprises has adhesive layer by the battery 202 that is buckled on the battery cover 102 between battery 202 and the battery cover 102.In second embodiment shown in Figure 3, battery cover 102 is independently.In these two embodiment, battery cover 102 comprises body 300 and Unitarily molded locking member 104.Body 300 and locking member 104 adopt injection molding process commonly known in the art to make.Body and locking member are made of plastics, preferably adopt Merlon.Yet, being different from the cellular locking member of GSM StarTACTM of the prior art previously discussed, locking member of the present invention comprises a metal spring 400 (Fig. 4) with the plastic outer molding.Fig. 5 has showed along the profile of the locking member 104 of Fig. 3 center line 5-5 interceptings.The profile of locking member 104 has been showed the spring 400 by plastics 403 outer molded.As shown in Figure 5, spring 400 is positioned at the center of locking member 104.Metal spring 400 (Fig. 4) preferably is made of beryllium copper, and thickness is preferably 0.156 mm.Can also use other metal, as spring steel and stainless steel.As shown in Figure 4, metal spring 400 is roughly U-shaped adapting to the shape of locking member, and comprises a plurality of stand-offs 402 that form along spring 400 outward flanges.In moulding process, stand-off 402 helps spring 400 is remained on the center of plastics.Equally, spring 400 preferably includes a plurality of grooves 404 and hole 406, correctly locatees in injection molding process to help spring 400.In injection molding process, groove 404 can also strengthen the material stream (being Merlon in the preferred embodiment) around the spring 400, thereby makes material and metal spring 400 combinations.
Those skilled in the art will appreciate that do not depart from the scope of the present invention or the prerequisite of spirit under, can carry out various improvement and conversion to the structure of device of the present invention and this device.For example, according to the instrument of the use in the moulding process, can improve a plurality of grooves 404 in the spring 400 and hole 406.
