Abstract
An installation device of an engineering vehicle vehicular speaker phone comprises a vehicular speaker phone and a support seat shell body, wherein the support seat shell body penetrates through an inner decorative plate and is fixedly connected with a vehicle cab top plate after clamping the inner decorative plate, and the vehicular speaker phone is installed in the support seat shell body. The installation device of the engineering vehicle vehicular speaker phone has the advantages that due to the fact that a transition component, namely the support seat shell body, is used between the vehicular speaker phone and the cab top plate, installation efficiency is improved, and tasks originally needing completing by two persons can be easily completed only by one person after the support seat shell body is used. Meanwhile, the support seat shell body can protect a wiring harness plug on the speaker phone from being interfered by inner decorative pieces, and the phenomenon of bad contact of connectors on the speaker phone is avoided.
Description
Technical field
The utility model relates to a kind of installation of loud speaker, particularly a kind of erecting device for the vehicle-mounted loudspeaker in the construction-vehicle cab.
Background technology
At present, vehicle-mounted loudspeaker on the engineering truck all be to be pressed on loud speaker on the interior trimming parts according to mode after, directly be fixed in the operator's compartment by screw or bolt.When adopting this mounting means, screw or bolt are fixed on the operator's compartment after penetrating interior trimming parts, relatively difficulty are installed, when especially adopting the mounting means of screw or bolt and screw, need inside and outside two people of operator's compartment to cooperatively interact and just can finish, so greatly improved assembly cost.
Chinese patent ZL200920305006.4 discloses a kind of loudspeaker installing structure, comprises face frame, loud speaker, and described frame below arranges heavy hole, and loud speaker is installed in the heavy hole, and the position, heavy hole of face frame arranges the stealthy phonate hole in heavy hole.This mounting structure is directly installed on the face frame loud speaker, does not need filtration members.This structure is used for the installation of the loud speaker of vision receiver, different from environment in the construction-vehicle cab, engineering truck is because engine noise is larger, so the interior trim with soundproof effect must be set in operator's compartment, the mounting means of loud speaker is after being pressed on loud speaker on the interior trimming parts, directly to be fixed in the operator's compartment by screw or bolt.
Chinese patent CN1153117A discloses a kind of vehicle with the installation constitution of loud speaker, when providing a kind of loud speaker to be contained on the door panel etc., does not produce the installation constitution of the vehicle-mounted loudspeaker of the unusual sound such as high-frequency vibration sound.Vehicle mounted loudspeaker is contained on the trim panel of vehicle, rear side is established the thrust of pillar-shaped near the flange of loud speaker, and this thrust directly or by buffer unit is combined with vehicle body iron plate indirectly.This invention relates to a kind of Slimline speaker and is contained on vehicle interior trim panel or the door panel.The interior trimming parts of general vehicle is all thinner, and the noise content that produces during engineering truck work is larger, and in order better to reduce driver's noise in one's ear, engineering truck can adopt the better interior trimming parts of the thicker sound-absorbing effect of thickness.
Summary of the invention
Goal of the invention: the purpose of this utility model provides a kind of erecting device of engineering truck vehicle-mounted loudspeaker, and it is simple, easy for installation that this device can be fitted this apparatus structure, can improve installation effectiveness.
Technical scheme: a kind of erecting device of engineering truck vehicle-mounted loudspeaker, comprise vehicle-mounted loudspeaker and bearing housing, captive joint with the vehicle cab top board after described bearing housing passes trim panel and blocks trim panel, described vehicle-mounted loudspeaker is installed in the bearing housing.
Described bearing housing comprises upper cover plate, base plate and connecting panel, and described connecting panel connects respectively upper cover plate and base plate; Described connecting panel is round tube shape structure, and described upper cover plate and base plate are cirque structure, and the internal diameter of described upper cover plate is less than the internal diameter of connecting panel, and the external diameter of described upper cover plate is greater than the external diameter of connecting panel; The external diameter of described base plate equates that with the internal diameter of connecting panel the bottom surface of described base plate is equal with the connecting panel bottom surface.
In order to make things convenient for the needs of vehicle-mounted loudspeaker wiring, the tube wall of described connecting panel is provided with wire hole.
Beneficial effect: by between vehicle-mounted loudspeaker and driving top board, using transition member bearing housing, improved installation effectiveness, originally needed collaborative finishing of the tasks of two people, behind use bearing housing, only needed a people easily to finish.Simultaneously the bearing housing can protect again wire harness plug on the loud speaker not to be subjected to the interference of interior trimming parts, avoids occurring the phenomenon of speaker plug place connector bad contact.
Description of drawings
Fig. 1 is the utility model scheme of installation;
Fig. 2 is the structural representation of the utility model bearing housing.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in the figure, a kind of erecting device of engineering truck vehicle-mounted loudspeaker, comprise vehicle-mounted loudspeaker 1 and bearing housing 2, described bearing housing 2 is installed on the vehicle cab top board 4 by bolt after passing trim panel 3 and blocking trim panel 3, and described vehicle-mounted loudspeaker 1 is installed in the bearing housing 2.
Described bearing housing 2 comprises upper cover plate 5, base plate 6 and connecting panel 7, and described connecting panel 7 is welded together to form cylinder-like structure with upper cover plate 5 and base plate 6 respectively; Described connecting panel 7 is round tube shape structure, and described upper cover plate 5 and base plate 6 are cirque structure, and the internal diameter of described upper cover plate 5 is less than the internal diameter of connecting panel 7, and the external diameter of described upper cover plate 5 is greater than the external diameter of connecting panel 7; The external diameter of described base plate 6 equates that with the internal diameter of connecting panel 7 bottom surface of described base plate 6 is equal with connecting panel 7 bottom surfaces.
In order to make things convenient for the wiring of vehicle-mounted loudspeaker 1, the tube wall of described connecting panel 7 is provided with wire hole 8.
