Description

The double layer carriage structure of exhibition vehicle

Technical field

The invention belongs to the touring vehicle technology field of showing, be specifically related to a kind of double layer carriage structure of exhibition vehicle

Background technology

The function of exhibition vehicle recited above is not limited to as producing touring mobile medical treatment car and the used one night stand car of culture's going to the countryside of showing, sending the doctor to go to the countryside used of (merchant) article.Be shown as example with product (commodity); Before; Enterprise or businessman have become the indispensable important means in the marketing by means of its product of media and communications, and comparatively common media advertisement has TV, wireless or electrophone, newspapers and periodicals and/or is erected in the advertising panel in the place that causes that easily people pay close attention to or the like.Though this propagate method can lack rendering effect to a certain degree making the public understand product, promptly lack atmosphere or claim popularity.And be difficult to even can't contact with the public is on-the-spot as commodity producers' marketing personnel.

are flowed with vehicle-mounted mode and are showed that its product or the performance of flowing can embody the displaying merchandise scene, the on-the-spot atmosphere of giving a performance; And owing to have flow effect, thereby all has unexpected effect at aspects such as alerting ability, selectivity, specific aim, present deal property and economy.

Disclosed Chinese patent document is made a general survey of in , and notification number CN2287590Y (a kind of foldable exhibition vehicle) and CN2408545Y (a kind of mobile show stand) etc. all has aforesaid effect." cabin is showed in vehicle-mounted turnover panel translation " that CN2685148Y recommends overcome CN2287590Y and the existing shortcoming of CN240854Y, specifically can be referring to the 1st section of the Instructions Page 3 of CN2685148Y.Again; CN1298565C provides " collapsible mobile show stand extension means " and the CN2685147Y announcement has " vehicle-mounted collapsible displaying cabin "; The former technique effect in these two patents can be referring to Instructions Page 3 the 14th to 18 row, and the latter's technique effect can be referring to the 3rd section record of Instructions Page 3 of this patent.And CN101409034A disclosed " lifting mechanism for LCD display screen holder of exhibition vehicle " can carry read-out on exhibition vehicle with up-down mode.

are not limited to above-mentioned document of giving an example all around exhibition vehicle; Though respectively have it long, objectively have common drawback, more particularly; The exhibition vehicle of mentioning in the above-mentioned patent documentation exists industry expectation for a long time and solves and unsolved all the time following technical matters: in the display scene; Client and businessman (displaying side) can produce instant negotiation and signatory situation unavoidably, yet, because on-the-spot clamour of exhibition vehicle and space are limited; Client and businessman are difficult to carry out at the scene business negotiation and even signatory, thereby influence bandwagon effect to a certain extent.

therefore; How to make exhibition vehicle being that the travelling trader who comes to discuss business provides good negotiation problem of environment to suffer from industry for a long time when warmly being the exciting atmosphere displaying merchandise, yet in disclosed patent and non-patent literature, all be not seen in the teachings that is able to use for reference.For this reason, the applicant has done long-term and good try, and under the secrecy provision of strictness, has done the experiment of simulation in the applicant plant area, and it is practicable that the result proves, and the technical scheme that will introduce below produces under this background
