Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention is described in detail below with reference to the attached drawings.
The utility model provides a glove compartment unlocking synchronizer for an automobile, which comprises a shell 1, two shaft cores 2, two return springs 5, two cushion pads 4 and two gear pieces 3, wherein the two shaft cores 2 are respectively arranged on the shell 1 in a sliding manner and used for connecting unlocking components of the glove compartment, and the two gear pieces 3 are respectively arranged inside the shell 1 in a rotating manner and used for connecting the shaft cores 2 and synchronously performing telescopic transmission; two gear 3 mesh each other, and two gear 3 set up with two axle core 2 one-to-one transmission respectively, and gear 3 rotates along with axle core 2 round trip movement. Two springs set up respectively between gear and casing 1, and the spring is leaned on casing 1 to fix and support, contradicts on the gear, supplies gear motion to provide restoring force and holding power, and two blotters 4 set up respectively in 2 trench of axle core for slow down the spring and promote the gear and reset the abnormal sound that produces when assaulting casing 1 to axle core 2.
Specifically, the two shaft cores 2 are arranged in a collinear manner and are opposite to each other, that is, when the present invention operates, only one of the shaft cores 2 needs to extend or retract, the gear piece 3 connected to the shaft core 2 rotates correspondingly, so that the other gear piece 3 is driven to rotate in the opposite direction through meshing, the moving direction of the other shaft core 2 is opposite to that of the shaft core 2, and the effect that the two shaft cores 2 are synchronously retracted or extended out of the housing 1 is achieved.
Further, the one end that axle core 2 is located gear piece 3 is provided with drive groove 21, and gear piece 3 is provided with transmission portion 31, and transmission portion 31 activity sets up in drive groove 21, and gear transmission portion 31 top is close to 2 drive groove 21 one side of axle core and is provided with the anticreep screens, can stop the gear and break away from the inefficacy that causes in activity deformation in-process 2 drive grooves 21 of axle core break away from gear transmission portion 31.
Further, a buffering pad 4 is arranged between the shaft core 2 and the shell 1, and the buffering pad 4 is used for reducing abnormal sound generated when the spring pushes the gear to the shaft core 2 to reset and impact the shell 1.
Furthermore, the gear piece 3 comprises a main body 32, a linkage part 33 and a rotating part 34 fixed on the main body 32, the linkage part 33 and the transmission part 31 are respectively arranged at two ends of the main body 32, and the linkage part 33 is two 0.6MM arc-shaped ribs, so that friction generated by contact with the shell 1 during movement is greatly reduced, and thus, the product is more smoothly used and has better hand feeling; two rows of engaging teeth 35 are arranged on the surface of the linkage portion 33 at intervals, the two rows of engaging teeth 35 are meshed in a staggered mode, the gear is effectively prevented from slipping and loosening or losing efficacy, the rotating portion 34 is rotatably connected with the mounting hole 22 of the shell 1, and the gear can be effectively kept balanced when a supporting force is given to the gear to rotate.
Furthermore, the ratio of the length of the arc surface of the linkage part 33 to the length of the shaft core 2 is 1:2-1:4, so that the driving stroke can be controlled, and the safety accident caused by overlarge extension amplitude of the shaft core 2 is avoided.
Furthermore, a mounting hole 22 is formed in one end, protruding out of the shell 1, of the shaft core 2, the mounting hole 22 is of an anti-falling structure with a gradually-opened arc line and a large outer part and a small inner part, and is easy to insert but cannot be separated from the anti-falling structure, so that the phenomenon that an opponent part is easy to separate after being mounted can be effectively avoided; mounting hole 22 runs through the both sides of axle core 2, the both sides of mounting hole 22 are provided with free portion 23 respectively, free portion 23 is located mounting hole 22, the one end of free portion 23 and the interior wall connection of mounting hole 22, the unsettled setting of the other end of free portion 23, free portion 23 deformation when free portion 23 unsettled design can let opponent's piece pack into props greatly, automatic shrink chucking after opponent's piece buckle targets in place, so free portion 23's design can let opponent's piece change equipment and detain the position anticreep.
Specifically, the elastic member is a torsion spring, the elastic member is installed in the housing 1, and two ends of the elastic member are respectively connected to the shaft core 2 and the housing 1. Namely, the elastic element always forces the shaft core 2 to move towards the direction of extending out of the shell 1, and when the shaft core 2 is retracted into the shell 1 by external force, the elastic element can be deformed to store energy. Through the arrangement of the elastic piece, the shaft core 2 can reset when no external force is applied, so that the stability and the reliability of the utility model are ensured.
Further, casing 1 includes two shells 11, and two axle cores 2, two reset spring 5, two blotters 4 and two gear spare 3 all set up between two shells 11, and two shells 11 lock joint each other, supply the inner assembly to provide support and spacing.
Furthermore, a guide groove 12 is formed in the shell 11, the shaft core 2 is provided with a guide portion 24, the guide portion 24 is arranged in the guide groove 12 in a sliding mode, 6 ribs are designed on the guide portion 24 of the shaft core 2, and the contact area between the guide portion 24 of the shaft core 2 and the guide portion 24 of the shell 11 is reduced, so that the friction force of the shaft core 2 during reciprocating motion is smaller, and the shaft core is smoother and free of blockage.
Although the present invention has been described with reference to the above preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
