At this time, the wearable smart key 100 according to an embodiment of the present invention is the vehicle control unit 120 accommodated in the wearing unit 110, so that the user does not need to carry it in a pocket or bag separately. It can be carried in state.

Accordingly, since the wearable smart key 100 according to an embodiment of the present invention can be transported and carried while the vehicle control unit 120 is worn on the body of the user, the risk of loss or theft can be greatly reduced. , the portability can be further improved.

To this end, the body portion 111 may have a seating groove 113 capable of accommodating the vehicle control unit 120 on one surface as shown in FIG. 3 , and the vehicle control unit 120 . may be detachably coupled to the seating groove 113 .

However, the wearable smart key 100 according to an embodiment of the present invention is not limited thereto, and the vehicle control unit 120 may be integrally formed with the body portion 111 .

On the other hand, the vehicle control unit 120 may be a type in which a separate battery (not shown) for driving is built-in. In this case, the vehicle control unit 120 may be a known smart key, and the wearing unit 110 serves as a wearing means for changing the vehicle control unit 120 to a wearable state on a part of the body. can

Unlike this, in the wearable smart key 100 according to an embodiment of the present invention, the vehicle control unit 120 is driven using power supplied from the flexible battery 140 built in the wearing unit 110 . can

To this end, a pair of contact terminals 130a and 130b corresponding to each other may be provided on the side of the vehicle control unit 120 and the seating groove 113, respectively, as shown in FIGS. 4 and 6 (b). .

Accordingly, when the body portion 111 and the vehicle control unit 120 are coupled, the driving control unit and the flexible battery 140 may be electrically connected to each other through the pair of contact terminals 130a and 130b. Through this, the vehicle control unit 120 may be driven using the power provided from the flexible battery 140 .

That is, the wearable smart key 100 according to an embodiment of the present invention can be driven using the power of the flexible battery 140, which has a much larger overall capacity compared to a general battery of the same size, thereby dramatically reducing the overall usage time. It can be increased, and since there is no need to embed a battery in the vehicle control unit 120 , the overall size of the vehicle control unit 120 can be remarkably reduced.

For example, the pair of contact terminals 130a and 130b may be contact terminals of a pogo pin type that move up and down through a spring. However, the pair of contact terminals 130a and 130b are not limited thereto, and various known methods may be applied as long as they are energized with each other through a direct or indirect contact method.

In the present invention, when the flexible battery 140 built into the wearing unit 110 serves to provide driving power to the vehicle control unit 120, the flexible battery 140 and A circuit board 132 electrically connected to the contact terminal 130a may be disposed, and an appropriate circuit element (not shown) or a circuit pattern (not shown) may be formed on the circuit board 132 side.

As another example, in the wearable smart key 100 according to an embodiment of the present invention, a battery is built-in in the vehicle control unit 120 to serve as a main battery, and a flexible battery built in the wearing unit 110 . It should be noted that the power of 140 may serve as an auxiliary battery of the vehicle control unit 120 . In this case, the above-described contact terminals 130a and 130b may be applied as an electrical connection method between the vehicle control unit 120 and the flexible battery 140 .

Meanwhile, when the vehicle control unit 120 is integrally formed with the body portion 111 , the contact terminals 130a and 130b for electrically connecting the vehicle control unit 120 and the flexible battery 140 are omitted. can be In this case, the body part 111 has a single circuit board built-in, and various circuit elements or driving for generating or transmitting a vehicle control signal to the circuit board and allowing or blocking power supplied from the flexible battery 140 . It may be implemented in a form in which devices and the like are appropriately mounted.

The flexible battery 140 is for providing driving power for the vehicle control unit 120 as described above, and may be in the form of a plate having a predetermined length and area, and has flexibility so that bending by an external force can occur. The branch may be a battery.

Accordingly, even if at least a portion of the flexible battery 140 is embedded in the band portion 112 side made of a flexible material or is embedded in the wearing unit 110 in a bent state with a predetermined curvature, the performance as a battery is prevented from being deteriorated. can In addition, since the flexible battery 140 is implemented as a thin battery, it is possible to realize a high capacity while relatively reducing the weight compared to a conventional battery such as a prismatic battery or a coin battery.

Such a flexible battery 140 may be embedded in the wearing unit 110 , and may be electrically connected to the circuit board 132 embedded in the body portion 111 .

In this case, the flexible battery 140 may be built-in only on the side of the band part 112 , but may be disposed to be embedded in the body part 111 and the band part 112 at the same time.

That is, as shown in FIGS. 4 and 5 , the flexible battery 140 may be disposed so that a portion of its entire length including both ends is located inside the band portion 112 , and the length of the remaining portion is It may be disposed to be located inside the body portion 111 .

To this end, a receiving groove 114 for accommodating a length of a portion including both ends of the flexible battery 140 is provided on the end side of the band portion 112 connected to both end sides of the body portion 111 to the inside. Each may be inlet-formed.

In this way, the flexible battery 140 applied to the present invention is built in the body part 111 side as well as the band part 112, thereby increasing the overall length compared to the type built in only the band part 112 or only the body part 111. Therefore, it is possible to further increase the storage capacity.

In addition, since only a portion of the entire length of the flexible battery 140 is built in the band part 112 side, the remaining part except for the part built in the band part 112 can be protected by the body part 111, In the process of use, the part embedded in the body part 111 can prevent bending. In other words, even if the band portion 112 is made of a soft material and repeated bending occurs in the course of use, the flexible battery 140 minimizes the portion where repetitive bending occurs during the entire length, thereby significantly reducing the possibility of deterioration or damage as a battery. can reduce

In addition, since only a part of the length of the entire length of the flexible battery 140 is accommodated on the receiving groove 114 side of the band part 112 , the receiving groove 114 is also formed only on a part of the total length of the band part 112 . can be Accordingly, when the band portion 112 is made of two members and both ends are fastened via a restraining means corresponding to each other so as to maintain a state worn on the user's body, to restrain both ends of the band portion 112 The constraint means for can be implemented in various ways.

Such a flexible battery 140 may include exterior materials 147 and 148 and an electrode assembly 141 as shown in FIG. 10, and the electrode assembly 141 is sealed inside the exterior materials 147 and 148 together with an electrolyte. may be in the form

In this case, in the flexible battery 140 applied to the present invention, patterns 146 and 149 for contraction and relaxation in the longitudinal direction may be provided on the sides of the electrode assembly 141 and the exterior materials 147 and 148 , respectively.

Preferably, the first pattern 149 formed on the exterior materials 147 and 148 and the second pattern 146 formed on the electrode assembly 141 may be provided to have the same directionality.

Such patterns 146 and 149 offset the length change caused by the curvature even if the flexible battery 140 is embedded in the wearing unit 110 and bending of the band part 112 occurs during use, so that the substrate itself is contracted. can be prevented or minimized.

In particular, when the flexible battery 140 applied to the present invention is arranged to be embedded in both the body part 111 and the band part 112, the patterns 146 and 149 include a part embedded in the band part 112 of the entire length. It may be formed so as to be formed so that the boundary region between the band portion 112 and the body portion 111 may also be included.

In this case, when the band part 112 is made of a soft material, if the band part 112 is repeatedly bent during use, the flexible battery 140 disposed in the receiving groove 114 may also be repeatedly bent. . In addition, the flexible battery 140 disposed in the boundary region between the band portion 112 and the body portion 111 may be bent to a predetermined curvature.

In the present invention, by forming the patterns 146 and 149 in portions where repetitive bending occurs and portions arranged in a bent state with a predetermined curvature to cope with repetitive bending and curvature, performance degradation or damage as a battery is delayed. can be prevented in

That is, in the flexible battery 140 applied to the present invention, the deformation amount of the substrate itself constituting the electrode assembly 141 and the exterior materials 147 and 148 is prevented or minimized through the patterns 146 and 149. By minimizing the amount of deformation of the substrate itself that may occur, it is possible to prevent the electrode assembly 141 and the exterior materials 147 and 148 from being damaged or the performance as a battery from being deteriorated.

However, the formation position of the patterns 146 and 149 is not limited thereto, and may be formed over the entire length of the flexible battery 140 or may be formed partially over a partial length. Also, at this time, the patterns 146 and 149 may be continuously formed in a direction parallel to the width direction of the electrode assembly 141 and the exterior materials 147 and 148 , or may be formed discontinuously.

In this case, the first pattern 149 and the second pattern 146 applied to the present invention may be formed so that the first pattern 149 and the second pattern 146 coincide with each other as well as the same directionality. This is to ensure that the first pattern 149 and the second pattern 146 always behave the same.

As described above, the flexible battery 140 applied to the present invention is formed on the electrode assembly 141 and the exterior materials 147 and 148 so that the patterns 146 and 149 for contraction and relaxation in the longitudinal direction generated during bending coincide with each other, respectively. Even when bending occurs in the longitudinal direction, the electrode assembly 141 and the exterior materials 147 and 148 can always maintain a uniform distance or contact state with respect to the entire length. For this reason, since the electrolyte to be sealed together with the electrode assembly 141 is uniformly distributed over the entire length, it is possible to prevent deterioration of performance as a battery.

For example, in the first pattern 149 and the second pattern 146 , peaks and valleys, respectively, may be formed in a direction parallel to the width direction of the exterior materials 147 and 148 and the electrode assembly 141 , and the exterior material (147, 148) and along the longitudinal direction of the electrode assembly 141, the peaks and valleys may be alternately disposed. In addition, the first pattern 149 and the second pattern 149 and the second pattern ( 146) may coincide with each other.

Specifically, the ridges and valleys of the first pattern 149 and the second pattern 146 may be formed in a direction parallel to a straight line parallel to the width direction of the exterior materials 147 and 148 and the electrode assembly 141 . and the ridges and valleys may be repeatedly disposed along the longitudinal direction (see FIG. 9 ).

Here, the peaks and valleys may be provided to have a cross section of any one of an arc-shaped cross-section including a semicircle, a polygonal cross-section including a triangle or a square, and a cross-section of various shapes in which arc-shaped cross-sections and polygonal cross-sections are combined with each other, and each The peaks and valleys may be provided to have the same pitch and width, or may be provided to have different pitches and widths.

Through this, even if the exterior materials 147 and 148 and the electrode assembly 141 are embedded in a bent state, the fatigue applied to the substrate itself through the patterns 146 and 149 can be reduced.

Meanwhile, as shown in FIG. 9 , the first pattern 149 and the second pattern 146 may have the same spacing between adjacent peaks or valleys, or may be provided to have different spacings. In addition, the same interval and different intervals may be provided in a combined form.

That is, the positive electrode 142 and the negative electrode 144 may be compressed, deposited, or coated with active materials 142b and 144b on one or both surfaces of the respective current collectors 142a and 144a.

In addition, the positive electrode current collector 142a and the negative electrode current collector may each have a negative electrode terminal 145a and a positive electrode terminal 145b for electrical connection with an external device from each body. Here, the positive electrode The terminal 145b and the negative terminal 145a may extend from the positive electrode current collector 142a and the negative electrode current collector 144a to protrude from one side of the exterior materials 147 and 148, and may be provided on the surface of the exterior materials 147 and 148. It may be in a form in which a part of the image is exposed.

In this case, the positive active material 142b and the negative active material 144b may contain a polytetrafluoroethylene (PTFE) component. This is to prevent the positive electrode active materials 142b and 144b and the negative electrode active material 144b from peeling off or cracking from the respective current collectors 142a and 144a during bending.

On the other hand, the separator 143 disposed between the positive electrode 142 and the negative electrode 144 may have a form in which the nanofiber web layer 143b is interposed on one or both surfaces of the nonwoven fabric layer 143a.

Here, the nanofiber web layer 143b may be a nanofiber containing at least one selected from polyacrylonitrile nanofibers and polyvinylidene fluoride nanofibers.

Preferably, the nanofiber web layer 143b may be composed of only polyacrylnitrile nanofibers to ensure spinning and uniform pores.

The exterior materials 147 and 148 may be formed of a plate-shaped member having a predetermined area, and may protect the electrode assembly 141 from external force by accommodating the electrode assembly 141 and the electrolyte therein.
