Description
Technical field
The utility model belongs to the steering wheel rim for an automobile loudspeaker and presses technical field aloud, is specifically related to a kind of loudspeaker that are used for the sedan steering dish and presses mechanism aloud.
Background technology
The loudspeaker that tradition is used for the motor turning dish are pressed mechanism aloud and generally are divided into floating type and push button.Wherein floating type is the mechanism that presses aloud of Purely mechanical, is made up of contact, spring, upper and lower base plate usually, and the arrangement space that needs is bigger, and structure is comparatively complicated, and cost is higher.Push button is that electronic switch is installed on the steering wheel, and cost is lower.But owing to need when pressing aloud by in the position of the switch, and the switch shape is less, so ease-to-operate is bad, generally is used for the lower automobile of price.
Summary of the invention
In order to solve the existing floating type problem that the arrangement of mechanism space is big, cost is high of pressing aloud, the utility model provides a kind of modular loudspeaker that are used for the motor turning dish to press mechanism aloud.
The concrete technical scheme of the utility model is following:
The loudspeaker that are used for the motor turning dish are pressed pedestal, static contact and the movable contact spring that mechanism comprises strip and block aloud; A pedestal end along its length is a head, and the other end is an afterbody; Seat head one side is the elongated slot of channel-section steel shape; Said elongated slot bottom is provided with a through hole along the groove depth direction, and the elongated slot bottom is along being provided with static contact in the length direction of groove, and said static contact is provided with the projection that raises up; And projection is stretched in the elongated slot of pedestal by the through hole of elongated slot bottom, and static contact is a steel disc; Movable contact spring is a spring steel plate, and the middle part bending, and an end of movable contact spring is positioned at the afterbody of pedestal, and the other end upwarps the elongated slot that is positioned at pedestal, and corresponding with the projection on the movable contact spring; The afterbody of pedestal offers the installation through holes that connects movable contact spring along short transverse; The bottom surface of seat head is provided with installs hook.
Said base material is an ambroin, and said static contact is installed in the elongated slot bottom of seat head through injection moulding, and an end of said movable contact spring is installed in the afterbody of pedestal through injection moulding.
The cross section that is positioned at the movable contact spring of seat head elongated slot is wavy.
The elongated slot that is positioned at the movable contact spring both sides of seat head is respectively equipped with spacer pin.
The useful technique effect of the utility model is: combined the floating type advantage that mechanism and push button are pressed mechanism aloud of pressing aloud, simple in structure, volume is little, can effectively practice thrift the steering wheel inner space.During installation, only need to play a bolt and can realize fixing, assembling is simple.The utility model consume material is less, and is with low cost.Volume is little, and position is more flexible on steering wheel.

Fig. 3 is the A-A cutaway view of Fig. 2.
Fig. 4 is the partial sectional view under the utility model assembling user mode.
Sequence number among the last figure: pedestal 1, through hole 11, hook 12, movable contact spring 2, static contact 3, projection 31, steering wheel skeleton 4 be installed, pressed aloud mechanism rack 41, loudspeaker are pressed push rod 51 aloud by castanets 5, loudspeaker.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done to describe further through embodiment.
Embodiment:
Referring to Fig. 2 and Fig. 3, the loudspeaker that are used for the motor turning dish are pressed pedestal 1, static contact 3 and the movable contact spring 2 that mechanism comprises strip and block aloud.Pedestal 1 material is an ambroin, and pedestal 1 end along its length is a head, and the other end is an afterbody.Pedestal 1 head one side is the elongated slot of channel-section steel shape; The elongated slot bottom is provided with a through hole 11 along the groove depth direction; The elongated slot bottom is along through injection moulding static contact 3 being installed in the length direction of groove; Static contact 3 is provided with the projection 31 that raises up, and projection 31 stretches in the elongated slot of pedestal by the through hole 11 of elongated slot bottom, and static contact 3 is a steel disc.Movable contact spring 2 is a spring steel plate; And the middle part bending, an end of movable contact spring 2 is installed on through injection moulding in the afterbody of pedestal 1, and the other end upwarps the elongated slot that is positioned at pedestal; The cross section of movable contact spring 2 that is positioned at the elongated slot of seat head is wavy, and corresponding with the projection 31 on the movable contact spring; Be separately installed with spacer pin in the elongated slot of movable contact spring 2 both sides.The afterbody of pedestal 1 offers the installation through holes that connects movable contact spring along short transverse; The bottom surface of pedestal 1 head is provided with reclinate installation hook 12.
During use,, loudspeaker are installed are respectively pressed aloud mechanism by press aloud mechanism rack 41 left sides and the right side of the steering wheel skeleton 4 below the castanets 5 at loudspeaker referring to Fig. 1 and Fig. 4.The concrete installation be, in the mount grooves that earlier the installation hook 12 of pedestal 1 head is stuck on the steering wheel skeleton 4, limits the motion of its side direction and above-below direction; Through the installation through holes of pedestal 1 afterbody pedestal 1 is pressed aloud on the mechanism rack 41 through being bolted to again, thereby the realization loudspeaker are pressed the fixing of mechanism aloud.Again horn hood is mounted on the steering wheel, can accomplishes assembling.According to the positioning design of horn hood, after the horn hood assembling, loudspeaker are pressed push rod 51 meeting precompressed aloud on spring steel plate by the loudspeaker on the castanets 5, make spring steel plate be in design attitude, the dotted line position of movable contact spring 2 as shown in Figure 3.Gap between movable contact spring 2 and the static contact 3 is exactly that loudspeaker are pressed stroke aloud at this moment; Loudspeaker are pressed mechanisms in series aloud among the loop that loudspeaker-power supply constitutes.Because under normal condition, spring steel plate does not contact with static contact 3, this loop is in open loop situations, so loudspeaker do not ring.When the driver applies when pressing power aloud by castanets 5 through loudspeaker, loudspeaker move downward by castanets 5, and promote that movable contact spring 2 moves downward and contact with projection 31 on the static contact 3, this loop closed loop at this moment, loudspeaker are rung.
