Embodiment
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing, hereinafter identical mark refers to identical element." Vertical direction " occurred in following examples refers to the above-below direction of accompanying drawing, " laterally " refers to the left and right directions of accompanying drawing, " low side " and " bottom " refer to the position of relative below in accompanying drawing, " high-end ", " ”,“ top, top " refer to the position of relative top in accompanying drawing, and " original state " refers to state when automobile gearshift mechanism is not used.
As shown in Figure 3, automobile gearshift mechanism comprises bulb, bulb comprises bulb body 1 and is arranged on the button 11 of bulb body 1 side surface, button 11 is connected with the joint that is arranged on bulb body 1 inside, joint moves downward for the push rod that promotes to shift gears, the gearshift push rod comprises push rod body 3 and is positioned at the locator protrusions 31 of push rod body 3 tops, be formed for accommodating the groove 41 of locator protrusions 31 on joint, leave gap 23 between the top of groove 41 and locator protrusions 31, push rod body 3 forms contact plane 32 in the bottom of locator protrusions 31, contact plane 32 contacts with the joint face.
When the user operates automobile gearshift mechanism, at first press button 11, button 11 promotes joint, and joint presses down the gearshift push rod again.Because joint contacts with the mutual face of contact plane on push rod body 3, promote the gearshift push rod and move downward.Owing between groove 41 and locator protrusions 31, leaving gap 23, between groove 41 and locator protrusions 31, contact hardly again, especially in vertical direction (on the direction pressed down along the gearshift push rod).Contacted with the joint face by contact plane 32 and change, therefore reduced noise.
In the present embodiment, as shown in Figure 3, joint 2 comprises the first link 2 and the second link 4, button 11 is for promoting the first link 2, the formation inclined-plane, top 42 of the second link 4, the first link 2 presses down inclined-plane 42, and groove 41 is formed on the bottom of the second link 4, and contact plane 32 contacts with the bottom faces of the second link 4.
As shown in Fig. 4-6, because button 11 is positioned at the side of bulb body 1, while pressing button 11, button 11 is laterally controlled the first links 2.Due to formation inclined-plane, top 42, the first links 2 of the second link 4 when the original state and the low end in contact on inclined-plane 42, in the process of the first link 2 transverse shiftings, gradually with the high end in contact on inclined-plane 42.Therefore, along with the first link 2 transverse shifting to the right gradually, the second link 4 moves down gradually.During original state, the first link 2 at spring 5(referring to Fig. 3) effect under to the left the biasing.When pressing button 11, need to overcome the elastic force of spring 5; When release button 11, the first link 2 is returned to the state of biasing to the left under the effect of spring 5.
Preferably, as shown in Figure 3, locator protrusions 31 and groove 41 are hemisphere, and the top height of groove 41 is higher than the top height of locator protrusions 31, and the bottom diameter of groove 41 equals the bottom diameter of locator protrusions 31.Due to the top height of the groove 41 top height higher than locator protrusions 31, in the process pressed down at the gearshift push rod, the top of groove 41 does not contact with the top of locator protrusions 31, can not produce collision.Locator protrusions 31 prevents the play of the second link 4 on left and right directions with can play coordinating of groove 41.In the present embodiment, because the bottom diameter of groove 41 equals the bottom diameter of locator protrusions 31, groove 41 contacts in bottom with 31 of locator protrusionss, for limiting the relative movement of left and right directions.During practical application, the bottom diameter of groove 41 can be slightly larger than locator protrusions 31, is convenient to the assembling of locator protrusions 31 and groove 41, only has small play between the two on left and right directions.Simultaneously, the fixing frame 6 in Fig. 3-6 also plays the effect of restriction the second link 4 and gearshift push rod play on left and right directions.
Preferably, the bottom of push rod body 3 is provided with for supporting the Compress Spring (not shown) of gearshift push rod.During original state, Compress Spring plays the effect of supporting push rod body 3, and push rod body 3 is contacted with joint maintenance face.When push rod body 3 is pressed down, Compress Spring is further compressed, and Compress Spring applies larger reaction force to push rod body 3, makes to contact closelyr between push rod body 3 and joint, prevents noise.When release-push 11, push rod body 3 is returned to initial position under the effect of Compress Spring.
Above-described is only principle of the present utility model and preferred embodiment.It should be pointed out that for the person of ordinary skill of the art, on the basis of the utility model principle, can also make some other modification, also should be considered as protection domain of the present utility model.
