Armrest for vehicle parking brake {ARMREST FOR VEHICLE PARKING BRAKE}

The present invention relates to an armrest for a vehicle parking brake, and more specifically, to an armrest for a vehicle parking brake that can be easily attached and detached from the parking brake according to the needs of the vehicle occupants and allows the occupant's arms to be comfortably supported. It's about.

In general, an armrest is formed on the side of a seat and is a tool to provide comfort to the user and solve problems such as fatigue accumulation and arthritis by supporting the user's arms comfortably.

Normal vehicles have a parking brake on the right side of the steering wheel, but there is no separate armrest, so most drivers and passengers rest their arms in the storage space between the seats or use a separate tool such as a cushion to support their arms. I am using it.

However, the storage space between the seats is located behind the vehicle's parking brake, making it difficult to raise one's arms comfortably. In particular, drivers with weak arm strength or bus, taxi, and truck drivers who make a living by driving must drive long distances. Due to the severe accumulation of fatigue in the arm, an armrest that can hold the arm in an appropriate position according to the user's physical condition or posture is needed.

In describing the present embodiments, the same names and the same symbols may be used for the same components, and additional descriptions may be omitted.

Figure 1 is a perspective view of an armrest for a vehicle parking brake according to an embodiment of the present invention, Figure 2 is an exploded perspective view of Figure 1, Figure 3 is a diagram showing the first bracket and the second bracket of Figure 1, FIG. 4 is an example diagram illustrating that the second bracket of the armrest for the vehicle parking brake of FIG. 1 slides with respect to the first bracket.

Referring to FIGS. 1 and 2 , an armrest for a vehicle parking brake according to an embodiment of the present invention includes an armrest portion 100, a base block 200, and a support portion 300.

The armrest portion 100 supports the occupant's arms. The armrest portion 100 is a portion on which the passenger's arm is raised, and may be formed to be long in the front-to-back direction so that the arm can be stably supported.

Additionally, the armrest portion 100 may have a concave upper surface to stably support the occupant's arms. In this way, the armrest unit 100 may be provided with various types of armrest units 100, and the user selects the desired armrest unit 100 among the various types of armrest units 100 using the second bracket 320, which will be described later. It can be used in selective combination with .

The base block 200 is detachably coupled to the parking brake operating unit 10 of the vehicle. Inside the base block 200, an internal space is formed into which the coupling area of the parking brake operating unit 10 is inserted. The inner surface layer of the inner space is coated with an elastically deformable material, and can be deformed according to the shape of the bonding region and fitted into the bonding region.

In addition, the present invention is not limited to this, and at least a portion of the lower area of the base block 200 is provided with a suction plate so that it can be stably adsorbed to the upper surface of the parking brake operating unit 10. A dish-shaped adsorption rubber can be used as the suction plate.

In addition, the base block 200 has a long hole 210 on one side into which the lever 11 of the parking brake operating unit 10 is inserted. The long hole 210 is formed long to correspond to the moving direction of the lever 11. Specifically, the lever 11 can move back and forth between the position of the lever 11 when the vehicle is driven and the position of the lever 11 when the vehicle is braked, and the long hole 210 is the position of the lever 11. It may be formed to be longer than the reciprocating range of the lever 11 in the moving direction.

In this way, since the base block 200 has a long hole 210 into which the lever 11 is inserted, it can be detachably coupled to the operating unit 10 without interfering with the original function of the lever 11.

The base block 200 may further include a coupler 220. The coupler 220 may be formed to protrude from the upper end of the base block 200, and may be detachably coupled to the coupler hole 330, which will be described later.

Additionally, the coupler 220 may have a horizontal cross-sectional area that narrows toward the top. For example, the coupler 220 may be formed as a trapezoid with an upper side shorter than the lower side adjacent to the base block 200.

Through this, when the coupler 220 is coupled to the coupling hole 330 formed in a shape corresponding to the coupler 220, the cross-sectional area of the coupler 220 is formed to become narrower toward the top, thereby forming the coupling hole 330. It may be easily combined.

And, the coupler 220 may include a first coupler (not shown) and a second coupler (not shown).

The first coupler may form the inner center of the coupler 220, more precisely, the remaining portion excluding the side and top portions that are in close contact with the coupler hole 330.

The first coupler may be made of a material that has a small change in shape depending on temperature. For example, the first coupler may be made of urethane resin, which has little thermal deformation depending on temperature, or it may be made of ceramic metal, which has little thermal deformation. Alternatively, it may be made of a nickel and iron alloy such as Invar (FeNi36), which has a low coefficient of thermal expansion.

The second coupler may form an outer surface of the coupler 220, more precisely, a side portion and an upper end portion that are in close contact with the coupling hole 330.

The second coupler may be formed of a polymer material with a shape memory effect. In other words, the second coupler is made of a polymer composite with a negative thermal expansion coefficient that contracts by heat, so it maintains a constant volume at normal room temperature, and shrinks when it reaches a relatively high operating temperature, reducing the volume. You can.

The second coupler may be made of a material whose shape changes greatly depending on temperature. For example, the second coupler may be made of an alloy or polymer material with the so-called shape memory effect, which utilizes the property of shape memory alloy or polymer materials to change their physical properties depending on temperature. That is, the second coupler may be made of an alloy containing nickel and titanium, or may be made of a shape memory alloy such as an alloy containing copper, zinc, and aluminum. Alternatively, it may be made of a polymer material containing a negative thermal expansion material. For example, the second coupler may be made of a polymer composite with a negative thermal expansion coefficient that shrinks by heat by dispersing a material with negative thermal expansion into a metal or resin. Materials with negative thermal expansion include Ruthenate Ceramics, ZrW2O8, BiLaNiO3, and BiNiFeO3.

This second coupler maintains a constant volume at room temperature, but when it reaches a relatively high operating temperature, it shrinks and the volume decreases.

Meanwhile, the coupler 220 may further include a battery (not shown) and a heating wire (not shown) as a means to increase the temperature of the second coupler.

The battery may be placed inside the first coupler, and may be detachably installed in the battery installation groove provided on the side of the first coupler. Here, an opening corresponding to the battery installation groove may be formed on the side of the second coupler. The battery can be turned on by a switch provided on the side of the base block 200 to supply current to the hot wire, or can be turned off to block the current supplied to the hot wire. Additionally, the battery can be charged and used as needed using the charging port provided on the side of the base block 200.

The heating wire is electrically connected to the battery and can be uniformly disposed inside the second coupling hole.

The operation of the coupler 220 according to this embodiment will be described as follows.

First, at room temperature, the second coupler maintains a constant volume.

Here, when the switch is turned on and current is applied from the battery to the heating wire, the temperature of the second coupler increases, and the second coupler, which reaches the operating temperature due to the increase in temperature, may shrink and decrease in volume.

In this way, the coupler 220 can be inserted into the coupler hole 330 in a state where the volume of the second coupler is contracted.

After inserting the coupler 220 into the coupler hole 330 and turning off the switch to block the current applied from the battery to the heating wire, the temperature of the second coupler gradually decreases and reaches room temperature. The second coupler, which has reached room temperature, expands due to the shape memory effect and returns to its normal shape. Due to the expansion force of the second coupler, the outer surface of the second coupler can be uniformly pressed and adhered to the inner surface of the coupling hole 330.

In this way, due to the expansion force of the second coupler inserted into the coupling hole 330, the coupler 220 is compressed with a strong force against the coupling hole 330, thereby increasing the coupling force, and thus, acting on the armrest portion 100. Despite the load, the solid coupling state of the support portion 300 to the base block 200 can be stably maintained.

Then, when the switch is turned on again and current is applied from the battery to the heating wire, the temperature of the second coupler increases, and the second coupler, whose temperature rises and reaches the operating temperature, may shrink and become smaller in volume. Accordingly, the support portion 300 can be easily separated from the base block 200.

In this way, by including a second coupler whose volume changes depending on the operating temperature, the coupling compatibility of the support portion 300 with respect to the base block 200 is increased, and the base block 200 is used for the parking brake operating portion 20 of various vehicles. ) There is an advantage in that the base block 200 and the support portion 300 can be combined while maintaining a stable state of solid connection even by replacing only the base block 200 and the support portion 300.

The support portion 300 supports the armrest portion 100 from the base block 200. At this time, the support part 300 may be formed in an 'L' shape to effectively support the armrest part 100 from the base block 200, and has a first bracket 310 and a second bracket 320.

The first bracket 310 is coupled to the base block 200 and may include a coupling hole 330 provided on the lower surface to which the coupling tool 220 is detachably coupled. Additionally, the first bracket 310 may be positioned higher than the position of the lever 11 when the vehicle is braked. Through this, even when the lever 11 moves back and forth between the position of the lever 11 when the vehicle is driven and the position of the lever 11 when the vehicle is braked, the lever 11 is in contact with the armrest portion 100. You can move without it.

The second bracket 320 is disposed above the first bracket 310 and is coupled to the armrest portion 100. Also, the second bracket 320 can be slidably coupled to the first bracket 310.

Meanwhile, referring to FIG. 3, the first bracket 310 may include an exposed hole 311, a ball 312, and a spring 313, and the second bracket 320 may include a guide line 321 and a plurality of It may include two seating holes 322.

The exposed hole 311 is formed on the side of the first bracket 310, and the spring 313 can elastically press the ball 312 toward the exposed hole 311. The guide line 321 may be formed to be recessed inside the second bracket 320, and the plurality of seating holes 322 may be arranged to be spaced apart from the guide line 321 along the direction in which the guide line 321 is formed. You can.

Referring to Figures 3 and 4, the operation of sliding the second bracket 320 with respect to the first bracket 310 according to this embodiment will be described as follows.

As the second bracket 320 slides along the guideline 321, a portion of the ball 312 pressed toward the exposed hole 311 by the spring 313 is seated in the seating hole 322, thereby forming the second bracket 320. ) can be fixed to the first bracket 310.

In this way, as the second bracket 320 slides with respect to the first bracket 310, the ball is seated in each seating hole 322, so that the position of the armrest 100 can be naturally adjusted according to the position of the passenger's arm. And the gap between the end 101 of the armrest 100 and the end 12 of the lever 11 can be adjusted.

If you want to move the lever from the position of the lever 11 when the vehicle is braked to the position of the lever 11 when the vehicle is driven, the end 101 of the armrest 100 and the lever 11 If the gap between the ends 12 is too narrow, the rider may feel uncomfortable holding the lever 11 and moving the lever 11.

In this case, the second bracket 320 is slid relative to the first bracket 310 to widen the gap between the end 101 of the armrest 100 and the end 12 of the lever 11, allowing the rider to use the lever. When moving (11), the lever (11) can be moved without being hindered by the armrest unit (100).

As above, in the armrest for a vehicle parking brake according to the present invention, the base block 200 has a long hole 210 into which the lever 11 is inserted, without interfering with the original function of the lever 11. It can be easily attached and detached from the control unit 10 according to the needs of the vehicle occupants.

In addition, the present invention includes not only an insertable coupling between the base block 200 and the vehicle parking brake operating unit 20, but also an insertable coupling between the support part 300 and the armrest part 100 and the support part 300 and the base block 200. Due to its structure, it is very easy to combine and separate parts, providing convenience not only for installation and assembly but also for use.

In addition, the present invention includes a second coupler whose volume changes depending on the operating temperature, thereby increasing the coupling compatibility of the support part 300 with the base block 200, so that it can be used for the parking brake operating part 20 of various vehicles. Even if only the base block 200 is replaced, the base block 200 and the support portion 300 can be coupled while stably maintaining a firm connection state.

In addition, in the present invention, the second bracket 320 is slidably coupled to the first bracket 310, so that the gap between the end 101 of the armrest 100 and the end 12 of the lever 11 is reduced. It is adjustable, so when the rider moves the lever 11, he or she can move the lever 11 without being hindered by the armrest unit 100.

As described above, preferred embodiments of the present invention have been described with reference to the drawings, but those skilled in the art may vary the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. It can be modified or changed.
