Description

Technical Field

[0002] At present, in the field of smart home appliances, such as curtain opening and closing devices charging on curtain rails, wired charging devices are widely used to provide continuous and stable power supply for devices moving along a fixed path. The existing technology is only for large opening and closing devices fixed on the wall. When installing the device, it is necessary to install a socket next to the opening and closing device, and connect it to the household socket to achieve continuous charging. However, it is large in size and consumes a lot of power. Since the curtain opening and closing device is installed on the curtain rail, it is high off the ground and difficult to operate, so it is troublesome to cut off the power, and it is necessary to install a socket next to the opening and closing device, which is more troublesome.

[0003] Existing power supply equipment for track-type applications usually uses fixed-length transmission lines to connect power to mobile devices. These devices often use traditional plug-in connectors to establish electrical connections, which is a time-consuming and inefficient process. Since the length of the transmission line is fixed, it is impossible to adjust the length of the exposed transmission line according to the different track lengths, resulting in excess cables that may entangle or interfere with the operation of the equipment. In addition, the traditional connection method lacks convenience, cannot quickly and reliably access the power supply, and is difficult to adapt to the power supply needs of tracks of different lengths. Therefore, these restrictions hinder the control of the length of the transmission line, reduce operational efficiency, and limit the applicability of the equipment in various track lengths.

It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0045] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0046] Embodiment 1:

[0047] Combination Figures 1 to 10 As shown, an embodiment of the present invention provides a wired charging device 200, including a charging body 210, wherein both sides of the charging body 210 are respectively provided with magnetic suction components 230 for connecting with the power transmission component 300, and one end surface of the charging body 210 is provided with a wire collection component 220.

[0048] It should be noted that the device consists of a track assembly 100 and a wired charging device 200, wherein the wired charging device 200 can be disassembled and installed on the track assembly 100, which is convenient and flexible. The core of the wired charging device 200 is the charging body 210, on both sides of which are installed magnetic suction assemblies 230 for connecting to the power transmission assembly 300. The magnetic suction method makes the connection faster and more convenient. A take-up assembly 220 is installed at one end of the charging body 210 for managing and controlling the length of the charging cable 223 to prevent problems caused by excessively long cables.

[0049] Combination Figure 6 As shown, the wire take-up assembly 220 includes a box body 221, and a storage compartment 222 for storing a charging line 223 is rotatably provided inside the box body 221, wherein the charging line 223 is electrically connected to the magnetic suction assembly 230; a coil spring 224 is provided in the middle of the storage compartment 222, one end of the coil spring 224 is fixed to the box body 221, and the second end of the coil spring 224 is connected to one end of the charging line 223. The function of the coil spring 224 is to provide a pulling force so that the charging line 223 can be automatically retracted into the box body 221 after use, so as to adjust the length of the charging line 223 and facilitate storage.

[0050] A connecting plate 225 and a pressing assembly 400 are provided on the box body 221. The pressing assembly 400 is provided with a one-way bearing 410. The one-way bearing 410 has an inner rotor 411 that can only rotate clockwise. One end of the inner rotor 411 abuts against the connecting plate 225. A return spring 412 is sleeved on the one-way bearing 410. The return spring 412 is used to push the pressing assembly 400 to move in a direction away from the connecting plate 225; wherein the connecting plate 225 is connected to the storage bin 222.

[0051] The return spring 412 is sleeved on the one-way bearing 410. When the user releases the pressing assembly 400, the return spring 412 pushes the pressing assembly 400 back to the initial position, away from the connecting plate 225. This design ensures that the charging cable 223 will not automatically retract when needed, so that the user can pull out the charging cable 223 of an appropriate length as needed.

[0052] The working principle of the present invention is as follows: when working, the magnetic suction component 230 is first connected to the power transmission component 300 to achieve conduction with the power source, and the exposed end of the charging line 223 is pulled out, and the charging line 223 extends out from the storage bin 222 to change the length of the charging line 223. During this period, the pressing component 400 of the take-up component 220 needs to be pressed to move the pressing component 400 toward the direction close to the connecting plate 225, so that the pressing component 400, the one-way bearing 410 and the storage bin 222 are tightly matched. Since the inner rotor 411 can only rotate clockwise, the storage bin 222 It can only rotate in one direction, which can limit the rotation of the coil spring 224, so that the charging cable 223 will not retract actively, so that the user can plug it into the guide rail power storage element; when the user pulls up the pressing component 400, the storage compartment 222 is no longer restricted, and the coil spring 224 will drive the charging cable 223 to retract to an appropriate length, thereby realizing the control of the length of the charging cable 223. At the same time, the magnetic suction method can quickly connect to the power supply, which is convenient to use and suitable for power supply work of tracks of different lengths; at the same time, the equipment is suitable for tracks of different lengths, which expands the scope of application and meets diverse power supply needs.

[0053] Combination Figure 7 As shown, in this embodiment, the pressing component 400 is provided with a first cavity 401, the one-way bearing 410 is installed in the first cavity 401, and a rubber block 420 is provided between the pressing component 400 and the one-way bearing 410, and the top wall of the first cavity 401 is provided with a bonding protrusion 402, which is used to bond with the rubber block 420.

[0054] During operation, by pressing the pressing component 400 downward, the bonding protrusion 402 on the top wall of the pressing component 400 is bonded to the rubber block 420, so that the pressing component 400, the one-way bearing 410 and the storage bin 222 are kept in a tight fit state, and the pressing component 400 will not rotate. At this time, the storage bin 222 can only rotate in the direction of pulling out the charging cable 223; after releasing the hand, the one-way bearing 410 stops the rotation of the storage bin 222, realizing the working requirement of pull and stop.

[0055] When the pressing component 400 is pulled upward, the pressing component 400 is separated from the rubber block 420, and the storage bin 222 is not fixed and can be freely rotated in the clockwise direction or counterclockwise direction. At this time, the working state is to pull out the charging cable 223 and then release the winding spring 224 to retract the charging cable 223 into the winding bin. When the user needs to recycle the charging cable 223, the pressing component 400 is pressed, and the rewinding component 220 will automatically rewind the pulled-out charging cable 223 for recycling.

[0056] In this embodiment, it is further explained that the pressing assembly 400 includes a first button 430 and a second button 440 sleeved on the first button 430; a limiting portion 441 is provided on the outer periphery of the second button 440, and the limiting portion 441 has an inclined surface 4411 extending in a clockwise direction and a vertical surface 4412 as a truncation position, and a limiting groove 2211 matching the limiting portion 441 is provided on the inner wall of the box body 221. Among them, the first cavity 401 and the bonding protrusion 402 are both provided on the second button 440.

[0057] Combination Fig. 9 As shown, in this embodiment, it is further explained that a toothed portion 431 is provided at one end of the first button 430, and the inclination angle of the toothed portion 431 matches the inclination angle of the inclined surface 4411; wherein, a sliding groove 2212 is provided on the inner wall of the box body 221, and a limiting protrusion 432 is provided on the outer wall of the first button 430, and the limiting protrusion 432 is slidably connected in the sliding groove 2212.

[0058] It should be noted that the pressing component 400 structure in the present solution is not a single component, but is divided into two main parts, namely the first button 430 and the second button 440. During actual operation, the user directly presses the first button 430 to further press the second button 440, so that the bonding protrusion 402 on the second button 440 and the rubber block 420 are bonded. At this time, the limiting protrusion 432 of the first button 430 slides along the sliding groove 2212, so that the toothed portion 431 at the front end of the first button 430 pushes the limiting portion 441 to move, and the stability of the movement is maintained through the mutual cooperation of the inclination angle of the toothed portion 431 and the inclined surface 4411.

[0059] When the first button 430 is pressed downward to a preset position, the first button 430 is rotated so that the limiting protrusion 432 is disengaged from the limiting protrusion 432 and rotated to a step position of the box body 221 close to the limiting groove 2211 (the step position here is set to be an inclined surface adjacent to the front end of the limiting groove 2211), so that the first button 430 is pressed by the step position of the box body 221, and cooperates with the bonding protrusion 402 and the rubber block 420 to limit the second button 440, that is, at this time, the first button 430 and the second button 440 are both limited, so that the pressing assembly 400, the one-way bearing 410 and the storage bin 222 remain in a tight fit.

[0060] When the pressing assembly 400 needs to be unlocked, the pressing assembly 400 is rotated back so that the first button 430 and the box body 221 are freed from restriction and enter the sliding groove 2212, and the pressing assembly 400 is freed from the rubber block 420 through the action of the return spring 412, and the storage bin 222 is not fixed.

[0061] It is further explained that the purpose of the two limiting mechanisms of the limiting protrusion 432 and the rubber block 420 is to avoid case failure caused by mechanical wear during repeated use of the pressing component 400, as well as failure of the bonding process or decreased bonding strength through mechanical snap-fit ​​and bonding, thereby effectively improving the service life.

[0062] It should be noted that the elastic force setting of the return spring 412 in the present solution is relatively special. It is set to be slightly larger than but close to the bonding force between the bonding protrusion 402 and the rubber block 420, so that after pressing the pressing component 400, the pressing component 400 can still briefly maintain the position of the pressing component 400, thereby maintaining the charging cable 223, but this time is relatively limited. Therefore, when maintaining it for a long time, it needs to be used in conjunction with rotation.

[0063] Combination Figure 8 As shown, in the present embodiment, it is specifically described that a positive conductive ring 2213 and a negative conductive ring 2214 which are respectively electrically connected to the magnetic suction assembly 230 are provided in the box body 221, a PCB board 226 is provided on one end face of the storage bin 222, and a positive spring piece 2261 and a negative spring piece 2262 are provided on one end face of the PCB board 226 close to the charging body 210, and the positive spring piece 2261 and the negative spring piece 2262 are respectively electrically connected to the charging cable 223; one end portion of the positive spring piece 2261 is inclined and extended in a direction close to the PCB board 226 and is kept in contact with the positive conductive ring 2213, and the negative spring piece 2262 is kept in contact with the negative conductive ring 2214.

[0064] It should be noted that, since the storage bin 222 of the present solution is rotatable, the corresponding conductive part used to conduct electricity also needs to rotate together. In order to avoid the entanglement and breakage of conventional wires during rotation, the conductive part between the storage bin 222 and the charging body 210 of the present solution is specially improved, that is, by matching the electrode spring clip and the conductive ring. It should be noted that the electrode spring clip should be arranged on the circumference of the conductive ring so that the electrode spring clip can always maintain contact with the conductive ring during rotation, thereby achieving electrical connection.

[0065] Combination Figure 5 As shown, in this embodiment, a rotating groove 211 is provided on one end face of the charging body 210 close to the take-up assembly 220, a protruding cylinder 227 is provided on one end face of the take-up assembly 220, and a rotating bearing 228 is provided between the protruding cylinder 227 and the rotating groove 211 to enable a rotational connection between the take-up assembly 220 and the charging body 210.

[0066] The charging body 210 of the wired charging device 200 is connected to the wire-receiving assembly 220 via a rotating bearing 228, so that the wired charging device can rotate 200 degrees, thereby making the angle of the charging cable 223 more flexible and allowing users to operate better.

[0067] Combination Figure 3 and Figure 4 As shown, in this embodiment, the magnetic attraction assembly 230 includes at least one group of conductors 231, each group of conductors 231 includes a positive conductor 231 and a negative conductor 231; a magnetic attraction portion 232 is provided at one end of the conductor 231, and a limiting plate 233 is provided at the other end; a sliding hole 212 is provided on the charging body 210, and the conductor 231 is slidably connected to the sliding hole 212, wherein the diameter of the limiting plate 233 is greater than the aperture of the sliding hole 212, and the limiting plate 233 is used to limit the sliding stroke of the conductor 231. A mounting column 213 is provided inside the charging body 210, and guide columns 214 are provided on both sides of the mounting column 213, respectively, and a push spring 215 is sleeved on the guide column 214, and one end of the push spring 215 abuts against the limiting plate 233. Through the function of the limiting plate 233, on the one hand, it is used to connect with the pushing spring 215 to realize the pushing effect on the conductor 231, and on the other hand, it can realize the limiting effect on the conductor 231 to prevent it from being pushed out of the charging body 210.

[0068] It should be noted that the magnetic attraction component 230 in the present embodiment is configured to be retractable. When the conductors 231 at both ends of the magnetic attraction component 230 are in contact with the power transmission component 300, the magnetic attraction portion 232 provides a magnetic connection, while the pushing action of the pushing spring 215 maintains a tight contact with the power transmission component 300, thereby maintaining the stability of the charging state.

[0069] In this embodiment, a supporting column 216 is provided on the side wall of the charging body 210, and a circular pipe is provided on the supporting column 216. A fastening bolt 217 is provided in the circular pipe, and a tightening piece 218 is provided at one end of the fastening bolt 217. The fastening bolt 217 is turned to adjust the height of the tightening piece 218.

[0070] Among them, the support column 216 corresponds to the position of the installation column 213. A through hole is opened in the middle of the installation column 213 and is connected to the circular pipe for operation to tighten the fastening bolt 217. By tightening the fastening bolt 217, the height of the top tightening member 218 is adjusted, thereby adjusting the distance between the charging body 210 and the guide rail assembly, thereby fixing the wired charging device 200 on the guide rail assembly.

[0071] In this embodiment, the power transmission assembly 300 includes a power supply seat 310 and a fixing seat 320 that are spaced apart. An adjusting bolt 330 is provided between the power supply seat 310 and the fixing seat 320. The adjusting bolt 330 is used to adjust the distance between the power supply seat 310 and the fixing seat 320. The fixing seat 320 is provided with a protrusion portion 321 arranged in an array on one end surface close to the power supply seat 310. The protrusion portion 321 is in a cone shape. The TYPE-C charging interface is connected to the positive and negative poles of the power supply seat 310. After installing the device, the TYPE-C interface is plugged into the charging interface of the curtain opening and closing device that needs to be charged to complete the installation of the device.

[0072] It should be noted that there are protrusions on the fixing seat 320 to increase friction, and a nut is placed inside. The screw on the power supply seat 310 passes through the adjusting bolt 330 to clamp the curtain cloth to fix the wired charging device 200.

[0073] It is further explained that two spaced conductive sheets 311 are provided on one end surface of the power supply seat 310, and the conductive sheets 311 are used to be magnetically connected with the magnetic suction assembly 230; wherein the conductive sheets 311 are galvanized iron sheets or magnet sheets, so as to prevent rust and achieve good contact with the magnetic suction head.
