Abstract
The utility model relates to an anti-loose structure of an automotive air conditioning controller, comprising a bottom shell installed on a cab dashboard base, an upper housing and a circuit board fixedly installed between the bottom shell and the upper housing. The anti-loose structure is characterized in that: the periphery of the circuit board is provided with a convex edge which can slightly deform under the action of pressure; the bottom shell is correspondingly provided with a jack pillar which can jack up the convex edge at the periphery of the circuit board so as to lead the circuit board to be firmly positioned when the bottom shell and the upper housing are tightly locked; and the upper housing is provided with a press pillar used for pressing the circuit board at the edge of the convex edge. The device is beneficial to the firm positioning of the circuit board of the automotive air conditioning controller, and improves the service life of the automotive air conditioning controller.
Description
Technical field
The utility model relates to a kind of anti-loosening structure of automotive air-conditioning controller.
Technical background
Circuit card in the existing automotive air-conditioning controller, its controller box body is fixing with screw.When running car, its car body can produce frequent vibration, thereby causes the screw in the controller box body loosening easily, finally can cause coming off and damaging of circuit card, thereby greatly reduces the service life of automotive air-conditioning controller.
Summary of the invention
The purpose of this utility model provides a kind of anti-loosening structure of automotive air-conditioning controller, and this device helps the firm location of the circuit card of automotive air-conditioning controller, the service life of having improved automotive air-conditioning controller.
The technical solution of the utility model be achieved in that it comprise be installed on drain pan, the upper encloser on the bridge instrumentation dish pedestal and be fixedly mounted on drain pan and upper encloser between circuit card, it is characterized in that: but described circuit card perimembranous is provided with the chimb of micro-deformation under the effect of pressure, but correspondingly on the described drain pan be provided with when drain pan is locked with upper encloser the chimb on the jack-up circuit card perimembranous so that circuit card is in the fore-set of firm location, described upper encloser is provided with the compression leg of the circuit card that is used to pin the chimb edge.
The utility model has the advantages that reasonable in designly, simple structure is skillfully constructed, and helps guaranteeing the firm location of the circuit card of automotive air-conditioning controller, the service life of having improved automotive air-conditioning controller.
Description of drawings
Fig. 1 is the D structure scheme drawing of the utility model specific embodiment.
