CN2619835Y - Case structure of luxurious arm type wide visual field bus rear-view mirror - Google Patents

Abstract

The utility model relates to a shell structure of a rear-view mirror, particularly the shell structure of the rear-view mirror of a luxurious arm type large visual field passenger car. The purposes of the utility model are to overcome the disadvantages of high cost of injection molding technique, low productivity effect of manufacturing technique for fiber glass reinforced plastics and thinness and low intensity of a shell of plastic suction technique, and to provide the shell structure of the rear-view mirror of a luxurious arm type large visual field passenger car, which adapt to a heat pressing technique adopted. The utility model adopts the technical proposal that the utility model is composed of a plastic shell which is shaped through design and is molded through the heat pressing, a mirror supporting component, an under-view mirror, a rear-view mirror and connection components which connect a body of the passenger car. The utility model has the advantages that the shell which is formed by the heat pressing technique has the common intensity, the thickness and the accuracy of an injection molding product; at the same time, the shell has the characteristic of low input cost of a die processed by the plastic suction technique. The utility model can satisfy the requirement of small amount production of shells of which the sizes equal the size of the shell of the rear-view mirror of a luxurious arm type large visual field passenger car.

Description

The housing structure of the big visual field of a kind of luxurious arm-type passenger vehicle back mirror

Technical field

The utility model is the housing structure about a kind of back mirror, and more particularly, the utility model is the housing structure about the big visual field of a kind of luxurious arm-type passenger vehicle back mirror.

Background technology

The big visual field of present luxurious arm-type passenger vehicle back mirror partly is made of plastic casing, mirror holder parts, following visor, back mirror and link etc.; The plastic casing of whole back mirror wherein has following three kinds of production methods: the one, adopt the method for injection mo(u)lding, and use this method, its advantage is: product yield height, casing rigidity height, dimensional accuracy height; But the injection mould cost is very big, die cost is not less than 200,000 yuan, be applicable to the production of certain scale, be difficult for transition, and the luxury car back mirror is mainly used in luxury bus, consumption is limited, therefore limited production lot, production lot is little, causes the actual cost valency higher, is on a sticky wicket in competition.The 2nd, adopt the glass-felt plastic manufacturing process, use this method, its advantage is: mould less investment, its expense are less than 1/20th of injection mould, and equipment needed thereby is also simple, so product transformation is fast; But the required cost of labor of this production method is too high, and output is very low, and producers' occupational diseases such as sunset lung that are easy to get, and contains carcinogen because of producing used auxiliary material again, so this technology has by superseded gradually gesture.The 3rd, plastic uptake technology, use this method, have following characteristics, its die cost is between between the two above-mentioned, be approximately 1/4th of injection mould, though the precision of the precision out of reach injecting products of product, but for the not high product of shell accuracy requirement also meet requirements, but because the type body of housing is big, camber greatly and darker, spillage of material is big, the productive costs height, significantly stretch simultaneously and cause the housing became uneven, what use because of plastic uptake technology again is the film section bar, and thickness is 1mm to the maximum, also is not suitable for the requirement of strength height, housing is thicker, the housing of the luxury car back mirror that the type body is bigger.

Summary of the invention

The purpose of the utility model is to overcome that the Shooting Technique cost is very high, glass-felt plastic fabrication process efficient is low and the thin low shortcoming of intensity of the housing of plastic uptake technology, a kind of employing heat pressing process is provided, and the housing structure of the big visual field of a kind of luxurious arm-type passenger vehicle back mirror that adapts to this technology.

The utility model is achieved by following technical proposals: the housing structure of the big visual field of a kind of luxurious arm-type passenger vehicle back mirror is made of with the link 5 that is connected bus body plastic casing 1, mirror holder parts 2, following visor 3, back mirror 4; Following visor 3 has the electric powered steering function with back mirror 4; It is characterized in that: described plastic casing 1 is divided into two sections at least, and every section plastic casing is by upper half shell, and two blocks of plastics of lower half shell are formed, between each piece plastic casing by the complete housing of the bonding one-tenth of lining cement, and through being bolted on the link 5.

The utility model has the advantages that: the housing that adopts heat pressing process to constitute has the common intensity of injecting products, thickness, precision; The low characteristics of mould input cost that have simultaneously plastic uptake technology again are fit to big, the little in batches production needs of type body as the housing of the big visual field of luxurious arm-type passenger vehicle back mirror.

Description of drawings

Fig. 1: be structural representation of the present utility model.

The specific embodiment:

Most preferred embodiment of the present utility model is described below.The housing structure of the big visual field of a kind of luxurious arm-type passenger vehicle back mirror as shown in Figure 1, is made of with the link 5 that is connected bus body plastic casing 1, mirror holder parts 2, following visor 3, back mirror 4; Back mirror 4 is connected on the plastic casing 1 by mirror holder parts 2, and following visor 3 is connected with plastic casing 1.Following visor 3 has the electric powered steering function with back mirror 4.The plastic casing 1 long 940mm of whole back mirror, wide 190mm, the cross section is 180 degree arcs, thickness of shell 2.5mm, whole housing are 90 degree, the camber of this plastic casing 1, the degree of depth is all bigger, it can be divided into two sections, and these two sections plastic casings are formed by upper half shell, two blocks of plastics of lower half shell.Every half shell is all through the design setting, carry out then hot-forming, the plastic casing 1 that last bonding one-tenth is complete.Described plastic casing 1 is through being bolted on the link 5.

Claims (1)

1. the housing structure of the big visual field of a luxurious arm-type passenger vehicle back mirror is made of with the link that is connected bus body (5) plastic casing (1), mirror holder parts (2), following visor (3), back mirror (4); It is characterized in that: described plastic casing (1) is divided at least two sections, and every section plastic casing is by upper half shell, and two blocks of plastics of lower half shell are formed, between each piece plastic casing by the complete housing of the bonding one-tenth of lining cement, and through being bolted on the link (5).
