There may be a gap in the longitudinal direction (or front and rear direction) between the contact parts 1100. Thus, when the contact portion 1100 expands in the longitudinal direction, the gap between the contact portions 1100 may be narrowed, and when the contact portion 1100 shrinks in the longitudinal direction, the interval between the contact portions 1100 may be widened. Therefore, even if the contact portion 1100 is expanded or contracted, it can be suppressed or prevented from being damaged.

In this case, a wire 1130 may be provided to electrically connect the contact parts 1100. Therefore, even when the contact parts 1100 are spaced apart from each other, when the power is supplied to any one of the plurality of contact parts 1100, the power may be supplied to the entire contact parts through the wire 1130. However, the method of electrically connecting the contact parts 1100 may be various.

Insertion groove 1311a may be formed extending in the height direction. An upper end portion of the second member 1120 of the contact portion 1100 may be inserted into the insertion groove 1311a formed in the upper protrusion of the body member 1311. The lower end of the second member 1120 of the contact portion 1100 may be inserted into the insertion groove 1311a formed in the lower protrusion of the body member 1311. Specifically, the upper end of the first plate provided in the second member 1120 is fitted into the upper insertion groove 1311a of the body member 1311, and the lower end is inserted into the lower insertion groove 1311a of the body member 1311. Can be fitted. Thus, the upper and lower portions of the second member 1120 may be supported.

At this time, the thickness L2 (or left and right length) of the insertion groove 1311a may be greater than the thickness L1 (or left and right length) of the contact portion 1100 inserted into the insertion groove 1311a. Can be. The size of the insertion groove 1311a in the front, rear, left, and right directions may be larger than the size of the portion inserted into the insertion groove 1311a of the largest inflated contact portion 1100. That is, a gap may be formed between the insertion groove 1311a and the second member 1120. Accordingly, the insertion groove 1311a may form a space in which the second member 1120 may be inserted to expand or contract, or may flow therein. Accordingly, the second member 1120 may freely expand in the insertion groove 1311a. However, the structure and shape of the insertion groove 1311a is not limited thereto, and may be formed in the shape of a groove.

In addition, the interval between the protrusions provided in the body member 1311 may be longer than the vertical length of the second plate provided in the second member 1120. Accordingly, the second plate may be positioned between the protrusions of the body member 1311 such that the second member 1120 may be stably fitted to the body member 1311, and even if the second member 1120 is expanded, the body member ( 1311 can be prevented or prevented from being caught or damaged between the projections provided in 1311. However, the structure and shape of the body member 1311 is not limited thereto and may vary.

The flow member may contact the contact portion 1100 in such a manner as to flow in a direction (or left and right directions) that intersect with one direction in the insertion groove 1311a. Thus, the flow member may be in close contact with the contact portion 1100 to support the contact portion 1100. The flow member may be provided in plurality. The plurality of flow members may be installed in the body member 1311 so as to sandwich at least a portion of the contact portion 1100, and may be in close contact with the contact portion 1100 in a flowable manner. Thus, even when the flow members are in close contact with the contact portion 1100, the contact portion 1100 may expand or contract. For example, the first flow member 1312 and the second flow member 1313 may be provided as a plurality of flow members.

The first flow member 1312 may be installed in the body member 1311 to apply a force to push the contact portion 1100 in the thickness direction (or left and right directions). The second flow member 1313 is disposed to face the first flow member 1312 and is installed on the body member 1311 to apply a force to push the contact portion 1100 in a direction opposite to the first flow member 1312. Can be. That is, the first flow member 1312 and the second flow member 1313 may be disposed to face each other with the insertion groove 1311a interposed therebetween. The second member 1120 of the contact portion 1100 may be located between the first flow member 1312 and the second flow member 1313. The first flow member 1312 and the second flow member 1313 may be installed at upper and lower protrusions of the body member 1311, respectively.

In addition, the first flow member 1312 and the second flow member 1313 may apply the same magnitude of force to the second member 1120. Accordingly, the force applied by the first flow member 1312 and the force applied by the second flow member 1313 cancel each other, so that the second member 1120 may be stopped. The first flow member 1312 and the second flow member 1313 are in contact with or in close contact with the second member 1120, and the second member 1120 is the first flow member 1312 and the second flow member 1313. It can be held in between. The first flow member 1312 and the second flow member 1313 include a contact body 1312a and an elastic body 1312b. The first flow member 1312 and the second flow member 1313 may further include a body 1312c.

The body 1312c has an inner space in which the elastic body is accommodated, and a portion facing the insertion groove 1311a may be opened. The body member 1311 may be provided with a through hole 1311b extending in a direction (or left and right directions) intersecting with an extending direction of the insertion groove 1311a, and the body 1312c is provided in the through hole 1311b. Can be fitted and fixed.

A plurality of through holes 1311b may be provided at the protrusions of the body member 1311 and may be disposed at both sides with the insertion groove 1311a therebetween. For example, the first flow member 1312 may be installed in the through hole 1311b disposed at the right side of the insertion groove 1311a, and the first through member 1311b disposed at the left side of the insertion groove 1311a may be formed. 2 flow member 1313 may be installed. The through hole 1311b may be in communication with the insertion groove 1311a.

In addition, the diameter of the body 1312c may be formed to be equal to or less than the diameter of the through hole 1311b. Threads may be formed on the outer surface of the body 1312c, and threads may also be formed in the through hole 1311b. Accordingly, the body 1312c may be inserted into the through hole 1311b, and the body 1312c may be tightened or released to adjust the position of the body 1312c in the through hole 1311b. However, the structure of the body 1312c and the manner in which the body member 1311 is installed may be various.

At least a portion of the contact body 1312a may be exposed into the insertion groove 1311a to be in contact with the second member 1120 of the contact portion 1100. The contact 1312a may be a spherical ball. The diameter of the contact body 1312a may be smaller than the diameter of the through hole 1311b. One side of the contact body 1312a may contact the second member 1120, and the other side may be connected to the elastic body 1312b. Therefore, the contact body 1312a may transmit the elastic force of the elastic body 1312b to the second member 1120.

At this time, at least a portion of the contact body 1312a may be inserted into the body 1312c and moved. Therefore, the contact body 1312a can move only in the extending direction of the inner space of the body 1312c. As a result, the contact body 1312a may move in a different direction to prevent the elastic force of the elastic body 1312b from being transmitted in a direction other than the left and right directions, thereby preventing the contact body 1312a from being in close contact with the contact unit 1100. have. However, the structure and shape of the contact 1312a may be various but not limited thereto.

The elastic body 1312b is connected to the contact body 1312a and may expand and contract toward the insertion groove 1311a (or to the left and right directions). The elastic body 1312b may extend in the thickness direction. One side of the elastic body 1312b may be connected to the wall surface inside the body 1312c, and the other side thereof may be connected to the contact body 1312a. Accordingly, the contact body 1312a may be pushed toward the insertion groove 1311a by the elastic force of the elastic body 1312b to maintain the state of being in close contact with the second member 1120.

When the second member 1120 is expanded as shown in FIG. 5A, the contact members 1312a of the two sides may be pushed by the second member 1120 to contract the elastic body 1312b in the horizontal direction. When the second member 1120 shrinks as shown in FIG. 5B, the elastic bodies 1312b on both sides thereof may be extended in the left and right directions so that the contact body 1312a may be in close contact with the second member 1120. Thus, even if the second member 1120 expands or contracts due to a temperature change in the insertion groove 1311a, the contact body 1312a may be maintained in close contact with the second member 1120 by the elastic body 1312b. have. Therefore, the second member 1120 may maintain a state supported by the elastic body 1312b. However, the structure and shape of the elastic body 1312b is not limited thereto and may vary.

The auxiliary body member 1314 may be installed in the body member 1311. The auxiliary body member 1314 may be manufactured integrally with the body member 1311. The auxiliary body member 1314 may be formed in a disc shape, and may be formed to increase in diameter from the body member 1311 toward the support unit 1320. The auxiliary body member 1314 may have an installation groove into which the support unit 1320 may be fitted.

In addition, the auxiliary body member 1314 may be formed of an insulating material. As a result, the auxiliary body member 1314 may prevent the power supplied to the contact unit 1100 from being transferred to the fixed unit 1200 or the carbonization chamber. However, the structure, shape, and material of the auxiliary body member 1314 may vary, without being limited thereto.

6 is a cross-sectional view showing the operation structure of the support unit according to an embodiment of the present invention. Hereinafter, a support unit according to an embodiment of the present invention will be described.

Thus, the buffer member 1322 accommodated in the case 1321 may extend or contract in the left and right directions. However, the structure and shape of the case 1321 and the method of coupling with the connection unit 1310 may be various.

The shock absorbing member 1322 may be installed in the inner space of the case 1321. The shock absorbing member 1322 may extend and contract in a direction (or left and right directions) that cross the moving direction of the moving vehicle 52. For example, the buffer member 1322 may be a spring. Accordingly, the shock absorbing member 1322 may push or pull the support member 1323 with an elastic force. However, the structure and shape of the buffer member 1322 may vary, without being limited thereto.

A portion of the support member 1323 may be located in the case 1321. Accordingly, one end of the support member 1323 may be moved left and right by the buffer member 1322 in the case 1321.

In addition, a locking portion may be formed in the center of the support member 1323. The other end of the support member 1323 may pass through the through hole formed in the second fixing member 1220 of the fixing portion 1200. The locking portion may have a size larger than the diameter of the through hole formed in the second fixing member 1220. Accordingly, when the support member 1323 passes through the through hole, the locking part may be caught while contacting one surface of the second fixing member 1220. However, the structure and shape of the support member 1323 may vary, without being limited thereto.

Coupling member 1324 may be formed in the shape of a nut. The size of the coupling member 1324 is larger than the diameter of the through hole formed in the second fixing member 1220, the coupling member 1324 may be fastened to the other end of the support member 1323. Accordingly, when the coupling member 1324 is tightened, the engaging portion of the support member 1323 may be in close contact with one surface of the second fixing member 1220, and the coupling member 1324 may be in close contact with the other surface of the second fixing member 1220. have. Therefore, the supporting member 1323 may be coupled to the second fixing member 1220.

In addition, when the coupling member 1324 is released from the support member 1323, the support member 1323 and the second fixing member 1220 may be separated. Thus, when any one of the plurality of support parts 1300 is damaged, only the damaged support part 1300 may be separated from the fixing part 1200 to be repaired or replaced. However, the manner of coupling the support member 1323 and the fixing part 1200 may be various.

Meanwhile, a guide groove 1321a extending in the thickness direction (or left and right directions) may be provided in the case 1321. The guide groove 1321a may be formed in accordance with the position of the portion of the support member 1323 inserted into the case 1321. Thus, some of the portions inserted into the case 1321 of the support member 1323 may be exposed to the outside by the guide grooves 1321a.

In addition, the support member 1323 may be provided with a projection (1323a) that is installed to be movable along the guide groove 1321a. That is, the protrusion 1323a may be provided at a portion of the support member 1323 inserted into the case 1321, and the protrusion 1323a may be located in the guide groove 1321a. The protrusion 1323a may move only along the extension direction (or left and right directions) of the guide groove 1321a. When the case 1321 attempts to rotate, the guide groove 1321a is caught by the protrusion 1323a to prevent rotation. Accordingly, the case 1321 may move only in the left and right directions by the guide grooves 1321 a and the protrusions 1323 a. Thus, when the impact is applied to the support 1300 in the moving vehicle 52, the guide groove 1321a and the protrusion 1323a may prevent the support 1300 from being twisted or rotated.

As shown in FIG. 6A, when the moving vehicle 52 pushes the contact part 1100 toward the fixing part 1200, the shock absorbing member 1322 of the support part 1300 may be contracted in the left and right directions. The shock absorbing member 1322 may absorb the shock while contracting in the left and right directions, and may extend in the left and right directions by an elastic force. Accordingly, the support part 1300 may return the position of the contact part 1100 to its original position while pushing the contact part 1100 toward the moving vehicle 52.

As shown in FIG. 6B, when the contact part 1100 is pushed toward the vehicle 52, the buffer member 1322 of the support part 1300 may be extended in the left and right directions. The elongated cushioning member 1322 may contract in the left and right directions by the elastic force. As a result, the contact part 1100 may be prevented from being excessively pushed toward the vehicle 52. As the shock absorbing member 1322 shrinks, the support 1300 may pull the contact 1100 toward the fixing part 1200, and the contact 1100 may be returned to its original position. Therefore, even if the contact portion 1100 is pushed in the left and right directions, the support portion 1300 can absorb the shock, and return the position of the contact portion 1100 to the correct position, thereby stably supplying power to the vehicle 52.

Hereinafter will be described the operation of the power supply according to an embodiment of the present invention. This will be described with reference to FIGS. 1 to 6.

The current collector 54 of the mobile vehicle 52 travels by traveling of the mobile vehicle 52. One surface of the current collector 54 is electrically connected to the power supply 1000. Therefore, the mobile vehicle 52 may be stably driven by the power transmitted from the power supply device 1000.

At this time, while the mobile vehicle 52 is traveling, a part of the contact portion 1100 of the power supply device 1000 may be pushed toward the fixing portion 1200. The support part 1300 provided in the power supply device 1000 may absorb the shock transmitted through the contact part 1100. That is, the shock absorbing member 1322 provided in the support 1300 may absorb the shock while contracting by the force pushed by the vehicle 52. The shock absorbing member 1322 may be elongated by an elastic force. Accordingly, the support part 1300 may return the position of the contact part 1100 to its original position while pushing the contact part 1100 toward the moving vehicle 52.

When a part of the contact part 1100 is pushed toward the fixing part 1200 side, the other part may be pushed toward the moving vehicle 52 side. The support part 1300 connected to the contact part 1100 pushed toward the vehicle 52 may absorb the shock. That is, the shock absorbing member 1322 provided in the support 1300 may be stretched to absorb the shock. The extended cushioning member 1322 may be contracted by an elastic force. Accordingly, the support part 1300 may return the position of the contact part 1100 to its original position while pulling the contact part 1100 toward the fixing part 1200.

In addition, the first flow member 1312 and the second flow member 1313 provided in the support 1300 may also absorb shocks transmitted from the vehicle 52. As a result, the shock may be mitigated in a double manner so that damage to the power supply 1000 may be effectively prevented.

On the other hand, the contact portion 1100 may expand or contract according to the temperature change. That is, the contact portion 1100 may contract during the winter season when the temperature is low and expand during the summer season when the temperature is high. Even when the contact portion 1100 expands or contracts, the first flow member 1312 and the second flow member 1313 maintain the state in close contact with the contact portion 1100 in accordance with the size of the changed contact portion 1100. Can support Therefore, the contact part 1100 may be maintained in the support part 1300 without being bent even with temperature changes.

In this way, the contact portion 1100, which may be in contact with the mobile device to supply power, may be supported by the support portion 1300 to be expandable and contractible. Thus, even if the contact portion 1100 expands or contracts due to temperature change, the support portion 1300 can stably support the contact portion 1100, and can suppress or prevent bending of the contact portion 1100. Therefore, the contact unit 1100 can stably supply power to the mobile device, and can prevent the support unit 1300 from being damaged by the expansion or contraction of the contact unit 1100, thereby extending the life of the power supply device 1000. .

In addition, the support 1300 may relieve the shock transmitted from the moving device to the contact portion 1100. Therefore, it is possible to prevent the contact portion 1100 or the support portion 1300 from being damaged by the shock transmitted from the moving device. Therefore, the power supply 1000 stably supplies power to the mobile device, so that the efficiency of the process may be improved.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims described below, but also by equivalents thereof.
