Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an exploded view of a gear lever unit according to an embodiment of the present invention, FIGS. 2 to 4 are views of a gear lever unit according to an embodiment of the present invention, FIG. 6 is a bottom view of the fixing member of the gear lever unit according to the embodiment of the present invention. FIG.

The gear lever unit according to the present invention includes: a gear knob 101 having an insertion hole 103 formed at a lower end thereof; A gear rod 201 having an upper end inserted into the insertion hole 103 of the gear knob 101 and engaged with the gear knob 101 and having a fixing groove 203 formed on opposite outer circumferential surfaces of the inserted upper end; And the gear knob 101 are provided on the inner circumferential surface of the insertion hole 103 side and wrap the upper end portion of the gear knob 101 inserted in the insertion hole 103. One end of the gear knob 101 slides into each of the fixing grooves 203, And a fixing member composed of a pair of engaging portions 301 engaged with the engaging portions 203 and a connecting portion 303 connecting the other ends of the engaging portions 301 with each other.

A guide hole 105 is formed in the outer circumferential surface of one side of the insertion hole 103 in a direction intersecting the insertion hole 103 and the fixing member can slide along the inner circumferential surface of the guide hole 105.

Conventional fastening of the gear knob 101 is performed by combining a male thread formed on the upper outer circumferential surface of the gear rod 201 and an inner thread of the gear knob 101, Is used to force the gear to rotate in a state in which the thread is not machined so as to prevent the gear knob 101 from rotating. Since the coupling structure requires a large turning force in the fastening process, the rubber hammer used for increasing the fatigue of the work increases and damages the appearance of the knob during the assembly process, and the time for assembly is also excessively consumed There is a problem that the process time is prolonged.

However, in order to apply the clip mounting space and the rotation preventing structure of the gear knob 101, the length of the knob relative to the conventional thread assembly structure is set to be 20 mm There is a problem that it is difficult to apply it to the small gear knob 101. [

On the other hand, the gear lever unit according to the present invention has a simple gear structure so that it is very easy to assemble the knob and the gear rod 201, and the time required is shortened, and after the assembly, the gear knob 101 can not rotate due to its physical structure Quality problems can be solved.

1, the structure of the gear lever unit of the present invention will be described in detail. An insertion hole 103 is formed at the lower end of the gear knob 101 so that the gear rod 201 is inserted into the insertion hole 103 So that a primary engagement with the gear knob 101 is performed. Fixing grooves 203 are formed on opposite outer circumferential surfaces of the upper ends of the gear rods 201, respectively.

5 to 6, the fixing member is configured to enclose the fixing groove 203 at the upper end of the gear rod 201. When one end of the gear is slid into the fixing groove 203 and is caught in the fixing groove 203 And a connecting portion 303 for interconnecting the pair of latching portions 301 and the other ends of the latching portions 301. That is, it has a structure similar to the U-shape.

2 to 3, the fixing member can be engaged with or separated from the fixing groove 203 of the gear rod 201 while sliding on the inner circumferential surface of the guide hole 105. When the fixing member is engaged with the fixing groove 203 of the gear rod 201, the fixing groove 203 is opposed to the outer circumferential surface of the gear rod 201 while preventing the gear rod 201 from being separated from the gear knob 101 And the fixing groove 203 is formed to surround the fixing groove 203, thereby preventing the gear knob 101 from rotating.

The gear lever unit according to the present invention has a simple structure and a reduced volume by allowing one of the fixing members to perform the function of the anti-rotation structure and the clip as compared with the conventional coupling structure of the clip and snap fit type. As a result, the degree of freedom of design of the gear knob 101 increases and it is possible to freely mount the gear knob 101 on the small gear knob 101 as well.

In addition, the time required for the assembling process is shortened. According to the statistical numerical value, the assembly time of the thread assembly is about 13 seconds and the assembly time of the clip and snap fit type takes about 5 seconds. The lever unit is completed in about 2 seconds. Therefore, the time required for the assembling process is remarkably shortened.

Inside the guide hole 105, an elastic body 401 is provided to provide an elastic force to slide the fixing member.

The elastic member 401 is a Z-shaped leaf spring. One side of the leaf spring is in surface contact with the connecting portion 303 of the fixing member, and the other side is in surface contact with the inner end of the guide hole 105.

2 to 3, the elastic body 401 provided inside the guide hole 105 allows the fixing member to slide through the elastic force of the elastic body 401. The elastic member 401 prevents free movement of the fixing member in the guide hole 105, The engagement of the fixing groove 203 of the gear rod 201 with the fixing groove 203 is maintained so that the coupling between the fixing groove 203 of the gear rod 201 and the fixing member is not released by an unintentional external force.

The Z-shaped plate spring elastic body 401 is used to make surface contact with the inner end of the fixing member and the guide hole 105 so that the fixing member can horizontally move inside the guide hole 105 .

One end of each of the pair of engaging portions 301 is tapered downward to form an inclined surface. When the gear rod 201 is inserted, the upper end portion of the gear rod 201 slides after contacting the inclined surface 305, 105, respectively.

One end of the gear rod 201 is tapered to form an inclined surface 205. When inserted into the gear knob 101, the inclined surface 205 of the upper end of the gear rod 201 is slid with the fixing member, And may be formed to move along the hole 105.

2 to 3, if the inclined surfaces 205 and 305 are not formed on the lower end of the fixing member engagement portion 301 or the upper end of the gear rod 201, The member can not smoothly move along the guide hole 105 but remains in the middle of the insertion hole 103 of the gear knob 101 and interferes with the insertion of the gear rod 201, have.

However, when the tapered inclined surfaces 205 and 305 are formed on the lower end of the fixing member engaging portion 301 or on the upper end of the gear rod 201, It is possible to smoothly and quickly proceed with the car joining process.

2 to 3, when the gear rod 201 is inserted, the inclined surface 205 of the gear rod 201 and the inclined surface 305 of the fixing member are in contact with each other, and when the gear rod 201 is inserted A part of the applied force is divided in the direction of the guide hole 105 by the inclined surfaces 205 and 305 and the fixing member can smoothly move along the guide hole 105 to the inside of the guide hole 105 through this force. The fixing member is rotated by the elastic force applied to the fixing member by the elastic body 401 provided inside the guide hole 105 as soon as the positions of the guide hole 105 and the fixing groove 203 of the gear rod 201 are aligned, And is engaged with the rod 201 fixing groove 203 to be engaged therewith. Whereby the assembling time of the gear lever unit can be shortened.

A slit may be formed below the guide hole 105 along the longitudinal direction of the guide hole 105.

A detaching hole 307 is formed in the connecting portion 303 of the fixing member, and the position of the removing hole 307 may be formed to correspond to the position of the slit.

It is also important to strongly maintain the coupling force when coupling the gear knob 101 and the gear rod 201. However, there is a case where disassembly is required for repair or replacement of parts as necessary.

4, when a separate tool is inserted into the removal hole 307 provided in the fixing member through the slit and the fixing member is pulled toward the inner side of the guide hole 105, the fixing groove of the gear rod 201 203 and the fixing member are separated from each other and the gear knob 101 is pulled at this time to easily disassemble the gear rod 201 and the gear knob 101.

However, since the coupling is not released naturally unless the fixing member and the fixing groove 203 are intentionally separated using a separate tool, there is no possibility that the gear knob 101 and the gear rod 201 are disassembled in an unfavorable situation do.

The fixing member is made of a steel material and can act as a mass damper.

Since the fixing member is required to simultaneously perform the rotation of the gear knob 101 while coupling the gear rod 201 and the gear knob 101, high rigidity is required. Therefore, it is preferable to use a rigid material such as a steel material, and since the weight is increased by using the steel material, the vibration damper can be prevented by performing the function as a mass damper.

While the present invention has been particularly shown and described with reference to specific embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims It will be apparent to those of ordinary skill in the art.
