Description

Technical Field

[0001] The present application relates to the field of electric curtains, and in particular to a self-charging curtain track structure. Background Art

[0002] Electric curtains mainly include two types: retractable and pull-type. The structure of pull-type electric curtains is relatively simple, so they are more widely used.

[0003] In the related art, the flat-pull electric curtain includes a slide rail and a curtain opener and closer. The curtain opener and closer is slidably connected to the slide rail. A transmission motor, a transmission roller, a battery and a control panel are arranged in the curtain opener and closer. The transmission motor and the transmission roller are transmission-connected. The battery is used to power the transmission motor. The control panel receives a remote control signal and sends a control signal. When the transmission motor receives the transmission signal, the transmission roller is driven to rotate, so that the transmission roller and the slide rail are rollingly abutted, thereby achieving the purpose of the curtain opener and closer pushing the curtain to fold or unfold.

[0004] With regard to the above-mentioned related technologies, if the battery is low on power, it is difficult for personnel to know and charge it in time, and it is usually necessary to increase the capacity of the battery so that the battery can provide power for a long time. However, the increase in battery capacity often further increases the size and weight of the battery, further causing inconvenience. Utility Model Content

[0005] In order to facilitate automatic charging of the curtain opener when the power is low and without further increasing the capacity of the battery, the present application provides a self-charging curtain track structure.

[0006] The self-charging curtain track structure provided in this application adopts the following technical solution:

[0007] A self-charging curtain track structure, comprising:

[0008] The suspension slide rail is provided with a sliding groove, and the sliding groove is extended along the length direction of the suspension slide rail;

[0009] A slide trolley is slidably embedded in the slide groove, the slide trolley is provided with a driving roller, the driving roller rolls against the inner wall of the slide groove, and one side of the curtain is connected and fixed to the slide trolley;

[0010] The charging terminal is arranged in the sliding groove. When the slide rail trolley moves to contact with the charging terminal, the charging terminal charges the slide rail trolley. When the slide rail trolley moves away from the charging terminal, the slide rail trolley stops charging.

[0011] By adopting the above technical solution, when the slide trolley moves to the end of the hanging slide rail, the charging terminal automatically charges the slide trolley so that the power of the slide trolley can be kept in a sufficient state, so that the battery in the slide trolley does not need to increase the battery capacity by increasing the volume, and can meet the power consumption requirements of folding and unfolding the curtains.

[0012] Optionally, at least one charging terminal is provided, and at least one charging terminal is provided at an end of the suspension rail.

[0013] By adopting the above technical solution, at least one charging terminal can meet the charging demand of the slide rail trolley, so that the slide rail trolley can be charged in time regardless of which end of the suspension slide rail the charging terminal is arranged on.

[0014] Optionally, one charging terminal is provided, and the charging terminal is arranged at the midpoint of the extension direction of the suspension rail.

[0015] By adopting the above technical solution, when there is only one charging terminal, by setting the charging terminal at the midpoint of the extension direction of the suspension slide rail, charging can be carried out when the two slide rail trolleys move to the middle position, which helps to control the unfolding and folding of larger curtains through the two trolleys, improves the unfolding and folding efficiency of the curtains, and at the same time can reduce the distance that the two moving trolleys need to move, save power consumption, and help maintain the overall size of the battery.

[0016] Optionally, two charging terminals are provided, and the two charging terminals are respectively arranged at two ends of the suspension rail.

[0017] By adopting the above technical solution, when the two charging terminals are respectively arranged at the two ends of the suspension rail, a single rail trolley can be charged when it moves to different ends of the suspension rail, so that the battery capacity in the rail trolley can be further reduced, and there is no need for the rail trolley to return to the end of the suspension rail with a unique charging terminal for charging, so that the remaining battery power is in a state of no shortage for a long time.

[0018] Optionally, there is at least one slide rail trolley, and at least one slide rail trolley is disposed on a side wall of the curtain close to the end of the hanging slide rail.

[0019] By adopting the above technical solution, when there is at least one slide trolley, the slide trolley is arranged at the end of the curtain close to the hanging slide rail, so that the slide trolley can pull or push the curtain from one side to realize the unfolding or folding of the curtain. At the same time, it can also be charged with the charging terminals at both ends, and does not need to move a long distance to be charged, which helps to reduce the capacity of the battery.

[0020] Optionally, a side wall of the slide trolley facing the ground is provided with a hanging ring, and the hanging ring is used for connecting and fixing the curtain.

[0021] By adopting the above technical solution, the setting of the hanging ring facilitates the indirect connection and fixation between the curtain and the slide trolley, so that the slide trolley can pull the curtain through the hanging ring to complete the folding and unfolding of the curtain.

[0022] Optionally, the slide rail trolley includes a battery, a servo motor and a trolley body;

[0023] The trolley body is provided with an installation groove and an embedding groove, the servo motor is embedded and fixed in the installation groove, and the battery is embedded and fixed in the embedding groove, and the battery and the servo motor are electrically connected;

[0024] The trolley body is rotatably provided with a roller, the roller is in rolling contact with the inner wall of the sliding groove, and the servo motor is transmission-connected with the driving roller.

[0025] By adopting the above technical solution, the main body of the trolley forms rolling contact through rollers and sliding grooves to reduce friction resistance. At the same time, the servo motor is powered by a battery, so that the servo motor can transmit the drive roller to drive the main body of the trolley to move, thereby realizing the unfolding and folding control of the curtains.

[0026] Optionally, a plug-in slot is provided on the side wall of the trolley body facing the charging terminal, an electrode connecting post is fixed in the plug-in slot, the electrode connecting post is connected to the battery, and the charging terminal is inserted into the plug-in slot and contacts the electrode connecting post.

[0027] By adopting the above technical solution, the plug-in slot and the electrode connecting column cooperate with each other, so that the vehicle body and the charging terminal move toward each other until the electrode connecting column and the charging terminal contact, so as to transmit and store electrical energy into the battery.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. When the slide trolley moves to the end of the suspension rail, the charging terminal automatically charges the slide trolley so that the power of the slide trolley can be kept in a sufficient state, so that the battery in the slide trolley does not need to increase the volume to increase the battery capacity, and can meet the power consumption requirements of folding and unfolding the curtains;

[0030] 2. When there is only one charging terminal, by setting the charging terminal at the midpoint of the extension direction of the suspension rail, the two rail trolleys can be charged when they move to the middle position, which helps to control the unfolding and folding of curtains with larger sizes through the two trolleys, improves the unfolding and folding movement efficiency of the curtains, and can reduce the distance that the two moving trolleys need to move, save power consumption, and help maintain the overall size of the battery;

[0031] 3. When two charging terminals are respectively arranged at the two ends of the suspension rail, a single rail trolley can be charged when it moves to different ends of the suspension rail, so that the battery capacity in the rail trolley can be further reduced, and the rail trolley does not need to return to the end of the suspension rail with a unique charging terminal for charging, so that the remaining battery power is in a state of no shortage for a long time.

[0042] Embodiment 1:

[0043] The present application embodiment discloses a self-charging curtain track structure. Figure 1 The self-charging curtain track structure includes a hanging rail 1, a rail trolley 2 and a charging terminal 3. The hanging rail is extended in the front and rear directions. A sliding groove 11 is provided on the front end surface of the sliding rail. The sliding groove 11 is extended toward the rear side and passes through the rear end surface of the hanging rail 1. The rail trolley 2 is provided with a driving roller 4. The driving roller 4 and the inner wall of the sliding groove 11 are rolled and abutted to drive the rail trolley 2 to move in the front and rear directions. The charging terminal 3 is fixed in the sliding groove 11 near the end of the hanging rail 1. When the rail trolley 2 and the charging terminal 3 are in contact, charging is carried out. When the rail trolley 2 and the charging terminal 3 are separated, charging is stopped, so that the rail trolley 2 can be in a relatively sufficient power state for a long time, and there is no need to increase the capacity of the battery 21, thereby reducing the increase in the volume of the rail trolley 2 caused by the expansion of the battery capacity.

[0044] Reference Figure 1 and Figure 2 The sliding groove 11 includes a roller sliding groove 111 and a clearance groove 112. There are two roller sliding grooves 111, which are respectively provided on the left and right inner walls of the clearance groove 112, so that the clearance groove 112 and the roller sliding groove 111 are connected to each other. The left and right walls of the slide rail trolley 2 are both rotatably connected with rollers 24, and the two rollers 24 are respectively embedded in the corresponding roller sliding grooves 111, and the rollers 24 roll and abut against the lower inner wall of the roller sliding groove 111, and the clearance groove 112 allows the slide rail trolley 2 to be embedded and slide along the front and rear directions.

[0045] Reference Figure 2 and Figure 3 The slide rail trolley 2 includes a battery 21, a servo motor 22 and a trolley body 23. Correspondingly, two rollers 24 are rotatably arranged on the left and right side walls of the trolley body 23. The upper side wall of the trolley body 23 is provided with a mounting groove 230. The notch of the mounting groove 230 is provided with a covering shell 25. The covering shell 25 is connected and fixed to the trolley body 23 by screws, and covers the mounting groove 230.

[0046] Reference Figure 3 and Figure 4 The cover shell 25 is provided with a rotation groove 251, and the left and right inner walls of the rotation groove 251 are provided with hinge holes. The left and right side walls of the driving roller 4 are fixed with a driving shaft 41. When the driving shaft 41 is inserted and rotatably connected to the corresponding hinge hole, the driving roller 4 is located in the rotation groove 251, and the driving roller 4 can rotate around the driving shaft 41. The lower side wall of the cover shell 25 is provided with a connecting groove 252, and the connecting groove 252, the hinge hole and the mounting groove 230 are connected. The servo motor 22 is fixedly embedded in the mounting groove 230. The drive shaft 41 and the output shaft of the servo motor 22 are both fixedly provided with a meshing gear 5 at one end adjacent to each other. The servo motor 22 controls the driving roller 4 to rotate through the meshing gear 5, and the peripheral outer wall of the driving roller 4 protrudes from the upper side of the rotation groove 251 and rolls against the upper inner wall of the clearance groove 112. When the driving roller 4 rotates in different directions, it drives the trolley body 23 to move toward the front or rear side.

[0047] In addition, refer to Figure 4 A connecting block 26 is fixedly provided on the lower side wall of the trolley body 23, and a hanging hole 261 is provided on two parallel side walls of the connecting block 26. A hanging ring 27 is sleeved in the hanging hole 261. The curtain can be connected in a limited position by providing corresponding hooks and hanging rings 27, so that when the trolley body 23 moves in different directions, the curtain can be driven to fold or unfold.

[0048] Reference Figure 4 The side wall of the trolley body 23 facing the charging terminal 3 is provided with an embedding groove 231 for the battery 21 to be embedded and connected. When the battery 21 is embedded in the embedding groove 231, an electrical connection is formed between the battery 21 and the servo motor 22 to supply power to the servo motor 22.

[0049] Reference Figure 4 and Figure 5The charging terminal 3 is fixedly provided with a charging terminal 31 on the side wall facing the trolley body 23, and the charging terminal 3 is provided with a USB plug interface 32 on the side wall away from the trolley body 23, so that an external charging head can be plugged in and powered by a USB charging cable. The trolley body 23 is provided with a plug slot 232 on the side wall facing the charging terminal 3, and an electrode connection column 233 is fixedly provided in the plug slot 232. The plug slot 232 and the charging terminal 31 are aligned in the front-to-back direction. When the charging terminal 31 is inserted into the plug slot 232, the electrode connection column 233 and the charging terminal 31 are in contact and abutment with each other to achieve the transmission of electric energy.

[0050] In addition, it needs to be further explained that the start-up of the servo motor 22 is controlled by a person through remote control, and the remote control person can control the steering of the servo motor 22 through remote control so that the trolley body 23 can move toward the set front or rear side. In the field of electric curtains, the control of curtain openers and closers by remote control is a conventional technical means and is not the focus of the invention concept of this application, so no further elaboration will be made.

[0051] Reference Figure 1 , the number of charging terminals 3 and the number of slide rail trolleys 2 are both set to at least one. In this embodiment, the number of charging terminals 3 and the number of slide rail trolleys 2 are both described as one. When there is only one charging terminal 3, the charging terminal 3 is embedded in the end yielding groove 112 of the suspension rail 1. The charging terminal 3 can be set at the front end or the rear end of the suspension rail 1, and the staff can set it according to the actual situation, so that the trolley body 23 can be automatically charged when sliding to the front end or the rear end of the suspension rail 1.

[0052] The implementation principle of a self-charging curtain track structure in an embodiment of the present application is as follows: when the trolley body 23 slides to the front end or rear end of the suspension rail 1 under the rotation of the driving roller 4, the charging terminal 31 is inserted into the plug-in slot 232, so that the charging terminal 3 can automatically charge the external power supply into the battery 21, so that the battery 21 remains in a fully charged state, so that the battery 21 does not need to have a large battery capacity, and the size of the battery 21 can be reduced.

[0053] Embodiment 2:

[0054] Reference Figure 5-7, which is different from the first embodiment, is that the charging terminal 3 is located at the midpoint of the length direction of the suspension rail 1, and the number of the rail trolleys 2 is two, and correspondingly, the charging terminal 3 is provided with two corresponding charging terminals 31 for the rail trolleys 2 to be inserted when charging, and the two rail trolleys 2 are respectively arranged at the two ends of the suspension rail 1. When the length of the suspension rail 1 is long, the midpoint of the suspension rail 1 in the length direction is used as the terminal of the forward direction of the two rail trolleys 2, so that when the two rail trolleys 2 move toward each other to the midpoint of the suspension rail 1, they can be charged, and the overall moving stroke of a single rail trolley 2 will not be long, and it is not necessary to consume a large amount of electricity, so there is no need to increase the capacity of the battery 21.

[0055] Embodiment three:

[0056] Reference Figure 6 and Figure 8 , which is different from the first embodiment in that the number of charging terminals 3 is two, and the number of rail trolleys 2 is one or two. Specifically, when the rail trolley 2 is one, even if the length of the suspension rail 1 is relatively long, the rail trolley 2 can be charged in time at both ends, so that the power of the battery 21 remains sufficient.

[0057] When there are two slide trolleys 2 and the curtain is large in size, the two slide trolleys 2 push the two parallel sides of the curtain respectively so that the curtain is folded toward the midpoint in the length direction. When the curtain is unfolded, the slide trolley 2 moves to the end of the hanging slide rail 1 and the charging terminal 3 for charging.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
