Description

Ceiling moving rail device for electronic devices {CEIL MOVING RAIL DEVICE OF ELECTRONICS}

The present invention relates to a rail device, and more specifically, a ceiling movable rail device for electronic devices that is connected to a power source installed on the ceiling and controls the supply of power, and is capable of changing the storage location of electronic devices so that they can move along the ceiling. It's about.

In general, since a rated voltage of 220V is supplied to homes and offices, a 220V power outlet that matches the rated voltage is installed embedded in the wall.

When you want to use an electronic device, you adjust the power switch of the electronic device to match the power supply and connect the power plug connected to the electronic device to the embedded power outlet on the wall to use the electronic device.

However, the location of the power outlet embedded in the wall is fixed regardless of the user's intention. Therefore, when the distance between the location where the user wants to use the electronic device and the power outlet is longer than the length of the wire, the wire has a predetermined length and has a power outlet connected to one end and a power plug to the other end. An extension device is used.

This wire extension device connects one power plug to an embedded power outlet on the wall and moves the power outlet at the other end to the relevant location to connect the power plug connected to the electronic device.

Here, if the distance between the electronic device and the embedded power outlet for power supply is shorter than the length of the wire of the wire extension device, the extra wires of the wire extension device are left unorganized on the floor between the electronic device and the power outlet. There was a problem with the aesthetics.

In addition, there are inconveniences such as the user's feet getting caught in a wire while moving, so the user wraps the excess wire by hand and organizes it by tying the wound wire with a fixing means such as a band.

However, when using this fixing means, when the position of the electronic device is moved and the tied wires are unfastened or rearranged, there is an inconvenience in using them, such as having to unwind them again, organize the wires, and tie them again.

Recently, due to the increasing number of electronic devices, securing a power outlet at home has not been easy due to space constraints in the housing structure, resulting in the problem of not being able to smoothly supply power for use or charging to electronic devices.

Figure 5 is a perspective view showing the movable roller part of the ceiling movable rail device of an electronic device according to an embodiment of the present invention, and Figure 6 is an installation of the rail portion and the mobile cart portion of the ceiling movable rail device of an electronic device according to an embodiment of the present invention. This is a side view showing the condition.

As can be seen from the drawings of FIGS. 4 and 5, the moving roller unit 230 is connected to the first motor 231 mounted and fixed to the first receiving bracket 222 and the motor shaft of the first motor 231. It includes a plurality of gear parts 232 that are meshed and connected, and a moving roller 233 that is connected to the driven gear 232b of the gear part 232 and is rotatable.

The gear unit 232 is a power transmission gear that is coupled together at different positions to transmit power. For example, the gear unit 232 is concentric with the driving gear 232a, which is connected and driven to the motor shaft of the first motor 231, and the moving roller 233, and is a driven device that provides rotational force to the moving roller 233. Between the gear 232b, the driving gear 232a, and the driven gear 232b, the rotational force of the first motor 231 is applied to the moving roller 233 in a state in which both the driving gear 232a and the driven gear 232b are engaged. Includes a transmission gear 232c that transmits.

Accordingly, the gear unit 232 has a structure in which the rotational force of the first motor 231 is easily transmitted to the moving roller 233 whose engagement position is determined by the first receiving bracket 222 even if the gears are positioned differently. Various embodiments can be adopted.

As can be seen from the drawings of FIGS. 4 and 6, a through opening 221a is formed in the mounting cap cover 221 so that a portion of the moving roller 233 can protrude and contact the lower bottom surface of the rail frame 100. It is done. Accordingly, the moving roller 233 may protrude upward through the through opening 221a and come into rolling contact with the lower bottom surface of the rail frame 100. To this end, it is important to ensure that the through opening 221a corresponding to the moving roller 233 has a size and shape that allows the moving roller 233 to sufficiently roll into contact with it.

In addition, the moving roller unit 230 is located on the same line as the moving roller 233 and is positioned on the lower floor of the rail frame 100 to maintain the posture during forward and backward motion while maintaining the balance of the mobile cart unit 20. It further includes an auxiliary roller 234 that is in rolling contact with each other. In particular, it is natural that the mounting cap cover 221 corresponding to the auxiliary roller 234 is formed with a through opening 221c to enable contact with the lower bottom surface of the rail frame 100. The auxiliary roller 234 may be disposed parallel to the moving roller 233 and coupled to the mounting cap cover 221 and the first receiving bracket 222 so as to be rotatable. The through opening 221c corresponding to the auxiliary roller 234 can secure a size and shape that allows the auxiliary roller 234 to make sufficient rolling contact.

The auxiliary roller 234 is merely a configuration that assists the moving roller 233 while maintaining the balance of the moving cart unit 20 by rolling contact with the lower floor surface of the rail frame 100, and rotates on the auxiliary roller 234. There is no driving means to transmit power.

Figure 7 is a perspective view showing the power connection module of the ceiling movable rail device for electronic devices according to an embodiment of the present invention, and Figure 8 is a perspective view showing the internal configuration of the power connection module according to an embodiment of the present invention.

The power connection module 240 according to an embodiment of the present invention is selectively connected to the first electrode plate 150 and the second electrode plate 160 located on the rail unit 10 connected to the power supply installed on the ceiling (c). It can be connected and serve as an intermediate medium that supplies or blocks use power and charging power to the electronic device 30.

The power connection module 240 consists of a selective rotation structure of the contact terminal 242 that can be selectively connected to or separated from the first and second electrode plates 150 and 160.

As shown in FIGS. 7 and 8, the power connection module 240 includes a terminal fixing block 241 of approximately circular shape. A pair of contact terminals 242 are provided on corresponding two sides of the terminal fixing block 241, with one side fixed and the other side extending obliquely in opposite outward directions. The terminal fixing block 241 and the contact terminal 242 are installed at positions corresponding to the first and second electrode plates 150 and 160 of the rail portion 10.

A rotation connecting shaft 243 of a predetermined length is integrally connected to the lower part of the terminal fixing block 241. At this time, the width of the terminal fixing block 241 may be formed to be relatively larger than the width of the rotation connecting shaft 243. A power line 244 is connected to the contact terminal 242. The power line 244 is in contact with the contact terminal 242 and extends along the rotation connection shaft 243 to the bottom of the rotation connection shaft 243 and is connected to the terminal pin portion 260. The power line 244 is made of a flexible material so that it can be curved at the step between the terminal fixing block 241 and the rotation connecting shaft 243.

In addition, a shaft housing 245 is provided on the outside of the terminal fixing block 241, the contact terminal 242, the rotation connecting shaft 243, and the power line 244 to surround these components. A cut groove portion 245a may be formed at the upper end of the shaft housing 245 so as not to interfere with the contact terminal 242 extending outward.

Figure 7 is a view showing the second fixing bracket 211 cut in the longitudinal direction so that the shape of the power connection module 240 can be clearly seen.

As can be seen from the drawing, a first flange 246 protruding in the radial direction is formed around the outer circumference of the shaft housing 245.

The shaft housing 245 can be stably rotated within the second fixing bracket 211 by the first flange 246. The second fixing bracket 211 of the second rail roller unit 210 corresponding to the first flange 246 will be provided with a flange receiving groove 211a into which the first flange 246 of the shaft housing 245 is inserted. You can. The flange receiving groove 211a may be formed as a circular inner groove so that the first flange 246 of the shaft housing 245 can be rotatably accommodated. Accordingly, the terminal fixing block 241, contact terminal 242, rotation connecting shaft 243, and power line 244 mounted on the inside of the shaft housing 245 as well as the shaft housing 245 are connected to the shaft housing 245. It can be rotated around the central axis.

Figure 9 is a diagram showing the power connection state of the power connection module of the ceiling movable rail device of an electronic device according to an embodiment of the present invention, and Figure 10 is a diagram showing the power connection of the ceiling movable rail device of an electronic device according to an embodiment of the present invention. This diagram shows the power disconnection status of the module.

As shown in FIGS. 9 and 10, the power connection module 240 rotates around the shaft housing 245 by the power transmission unit 250, which will be described later, so that the contact terminal 242 is connected to the first and second contact terminals 242. It may be selectively connected to the electrode plates 150 and 160 or may be separated from the first and second electrode plates 150 and 160. Accordingly, power from the power source can be selectively supplied to the electronic device 30 or the power supply can be blocked.

The contact terminal 242 is in contact with the first and second electrode plates 150 and 160 and is connected to power, that is, in a state where power is supplied to the electronic device 30, the second rail roller unit 210 of the mobile cart unit 20 When the second guide roller 213 provided in ) moves, there is a problem in that sparks occur when the contact is unstable at the contact terminal 242 and the power contact portion of the first and second electrode plates 150 and 160.

To solve this problem, according to an embodiment of the present invention, the contact terminal 242 supplies or blocks power to the first and second electrode plates 150 and 160 depending on whether the mobile cart unit 20 moves. You decide. That is, when the mobile cart unit 20 moves, sparks may occur at the contact terminal 242 and the first and second electrode plates 150 and 160. In order to prevent such sparks from occurring, the contact terminal 242 and the first and second electrode plates 150 and 160 are separated from each other. That is, contact instability at the power contact portions of the contact terminal 242 and the first and second electrode plates 150 and 160 can be fundamentally prevented. On the other hand, when the mobile cart unit 20 is stopped, the contact terminal 242 and the first and second electrode plates 150 and 160 are stably connected to each other so that power from the power source is supplied to the electronic device 30. .

Figure 11 is a perspective view showing the rotation structure of the power connection module by the power transmission part of the ceiling movable rail device for electronic devices according to an embodiment of the present invention, and Figure 12 is a ceiling movable rail for electronic devices according to an embodiment of the present invention. It is a perspective view showing the power transmission unit and the fixed cylinder in an elevated state with respect to the axial housing of the power connection module of the device, FIG. 13 is a side view of FIG. 11, and FIG. 14 is a side view of FIG. 12.

As shown in Figures 11 and 13, the power transmission unit 250 that transmits rotational power to the power connection module 240 is connected to the second motor 251 and the motor shaft of the second motor 251. It includes a first bevel gear 252, which is one of the shaft gears, and a second bevel gear 253 that crosses and engages the first bevel gear 252. Additionally, the power transmission unit 250 includes a fixed cylinder 254, which will be described later.

The first bevel gear 252 is a drive shaft bevel gear connected to the motor shaft of the second motor 251. The second bevel gear 253, which is a driven shaft bevel gear, is engaged with the first bevel gear 252 in a perpendicular state.

According to an embodiment of the present invention, the power transmission unit 250 uses first and second bevel gears 252 and 253, which are cross-axis gears, but is not necessarily limited thereto. In the case of this embodiment, the first and second bevel gears 252 and 253 are cross-axis gears. Worm gear or rack and pinion gear can be applied, and various modifications can be made.

A fixed cylinder 254 is integrally formed on the upper part of the second bevel gear 253 and is coupled to the shaft housing 245 to provide rotational force.

The fixed cylinder 254 rotates integrally with the second bevel gear 253 when the first and second bevel gears 252 and 253 engage with each other and rotate due to the rotational power of the second motor 251.

The fixed cylinder 254 makes surface contact with the corresponding surface of the locking groove 247a of the second flange 247 formed on the shaft housing 245 and forcibly rotates the second flange 247 to form a power connection module 240. ) Includes a protrusion 254a that rotates the whole. The protrusion 254a may be formed in two configurations facing each other along the circumferential direction of the fixed cylinder 254, but is not necessarily limited thereto, and may be formed in three or more configurations.

The locking grooves 247a are concavely formed on the inside of the second flange 247 and are composed of a number corresponding to the protrusions 254a. That is, the locking groove 247a and the protrusion 254a may be formed in a meshing structure of gears meshing with each other. However, the width of the locking groove 247a is formed to be relatively larger than the width of the protrusion 254a, so that the fixing cylinder 254 can be easily separated from the second flange 247.

When the rotational force of the second motor 251 is transmitted to the fixed cylinder 254 by the first and second bevel gears 252 and 253, the protrusion 254a of the fixed cylinder 254 is caught by the second flange 247. It rotates along the rotation path of the second flange 247 while being in close contact with the corresponding surface of the groove 247a. Accordingly, the contact terminal 242 of the power connection module 240 can be selectively connected to the first and second electrode plates 150 and 160 or separated from the first and second electrode plates 150 and 160. Accordingly, power from the power source can be selectively supplied to the electronic device 30 or the power supply can be blocked.

In addition, as can be seen from the drawing, the power transmission unit 250 is capable of moving in the axial direction with respect to the axial housing 245 of the power connection module 240.

The mobile cart unit 20 may be moved in the vertical direction with respect to the rail unit 10 to adjust the appropriate position of the mobile roller unit 230, etc. Therefore, the power connection module 240 and the power transmission unit 250 are configured so that the power transmission unit 250 of the mobile cart unit 20 can move in the vertical direction with respect to the power connection module 240 of the rail unit 10. ), it is necessary to form a gap of a predetermined interval.

As above, the gap between the power connection module 240 and the power transmission unit 250 is determined by the height of the protrusion 254a of the fixed cylinder 254 based on the height of the fixed cylinder 254, which is that of the second flange 247. It refers to a height difference formed relatively higher than the height, and this height difference allows the fixed cylinder 254 to form a structure that can slide in the vertical direction with respect to the shaft housing 245.

Due to the gap between the power connection module 240 and the power transmission unit 250, the power transmission unit 250 is capable of moving in the axial direction with respect to the power connection module 240. Due to the rotational power of 250, the contact terminal 242 of the power connection module 240 can be selectively de-contacted with the first and second electrode plates 150 and 160.
