Description

Charging stand

[ technical field ] A method for producing a semiconductor device

The invention relates to a charging seat, in particular to a charging seat with a charging wire capable of being stretched and automatically retracted.

[ background of the invention ]

Although most mobile devices currently use built-in batteries, the electronic devices that are long and continuously carried and used still need to use the detachable and replaceable rechargeable batteries to meet the use requirements. Most of the existing charging seats are designed in a way of conforming to various types of batteries, and a connector for charging is directly arranged at the bottom of the charging seat or on the charging seat body. When the detachable battery needs to be charged, the battery is placed on the charging seat, and the male and female connectors of the connector are butted for charging. The charging seat is used to ensure that the butt joint and the positioning of the connector are quicker, and the battery can be placed in an upright mode while charging, so that the occupied space can be saved. In addition, a plurality of charging seats can be expanded to be used simultaneously according to the use requirement.

[ summary of the invention ]

However, the direct arrangement of the connector on the base limits the types of the connectable rechargeable batteries, and the charger with different connectors must use a specific charging seat, so that the connector cannot be replaced by itself to meet the requirements of different rechargeable batteries.

In view of the above, an embodiment of the present invention provides a charging stand, including: base, containing seat, charging wire and elastic element. The containing seat is arranged in the base and comprises a containing groove body, a guide part and a positioning part. The guiding part is arranged at one end part of the accommodating groove body, and the positioning part is adjacent to the guiding part. The charging wire comprises a power wire, a stopping piece and a connector. The power line comprises a first end part and a second end part, the first end part is accommodated in the base, and the second end part is arranged in the guide part of the accommodating seat in a penetrating mode. The stopping piece is arranged at the first end part of the power line and is positioned in the base, and the connector is arranged at the second end part of the power line and is accommodated in the positioning part. One end of the elastic element penetrates through the power line, and the other end of the elastic element is fixed to the accommodating groove body.

Borrow this, through set up the charging wire that can stretch the use on the charging seat, can make the application of charging seat more extensive. Except that a plurality of groups of containing seats, charging wires and elastic elements can be arranged on the base of the charging seat at the same time to expand the number of the rechargeable batteries which can be charged at the same time. If need charge to the rechargeable battery of different connectors, can change the charging wire into the charging wire that has the suitable connector. Furthermore, the elastic element is used for connecting the containing seat and the charging wire, so that the charging wire can be stretched out of the containing seat when in use and can return to the containing seat under the action of elastic restoring force after use. In addition, the positioning part for positioning and placing the connector is arranged on the containing seat, so that a user can easily pull out the connector for use when using the charging device, and the connector is stretched, retracted and contained in the positioning part under the action of elastic restoring force after using, thereby avoiding the trouble and puzzlement of picking up the charging wire.

In some embodiments, the elastic element may be a tension spring, or a coil spring or other element that provides an elastic restoring force when stretched. The elastic element comprises two circular rings and a spring body, the two circular rings are respectively arranged at two ends of the spring body, each circular ring is vertical to the spring body, and when one of the circular rings is arranged on the power line in a penetrating mode, a right angle formed by the circular rings and the spring body is the second end facing the power line. Therefore, the elastic element can naturally move after being stretched and during resetting, and can not be intertwined with other wires or elements, and the elastic element can be more smooth during stretching and resetting.

In some embodiments, the guide portion includes a first open end and a second open end, and a side adjacent to the first open end has an oblique stopper, and the second open end has a U-shaped stopper. The inclined stop piece can provide a power line limiting function, so that the power line can move in the guide part, and the U-shaped stop piece further limits the length of the power line which can be stretched out. Further, there may be another U-shaped stop adjacent the first open end. The U-shaped stop member is used for limiting the power cord to be stopped at a specific position when the power cord is retracted and reset by the elastic restoring force, and the power cord is not continuously pulled back into the containing seat. In addition, in some embodiments, the size of the opening of the U-shaped stopper can be smaller than the size of the outer diameter of the stopper, so that the U-shaped stopper achieves the stopping effect through the difference between the size of the opening and the size of the stopper.

In some embodiments, the power cord has a tapered stop where it connects to the connector. The tapered stopper provides a buffer between the connector and the guiding portion when the power cord is pulled back to reset. Meanwhile, a stopping effect can be provided to prevent the connector from being pulled into the guiding portion and entering the accommodating seat.

In some embodiments, the positioning portion includes a U-shaped groove, a first retaining wall and a second retaining wall, and the first retaining wall and the second retaining wall are disposed on two opposite sides of the U-shaped groove. Even the first wall may have a guide slope and the end of the second wall may have a slope inclined toward the U-shaped groove. Therefore, when the connector is pulled back to the positioning part by the power line reset acting force, the connector can be guided and contained in the U-shaped groove under the action of the first retaining wall or the second retaining wall.

[ detailed description ] embodiments

Referring to fig. 1 to 4, fig. 1 is a schematic view of a charging base 1 according to a first embodiment of the invention, fig. 2 is a schematic view of a set of accommodating base, a charging wire and an elastic element in this embodiment, fig. 3 is a schematic view of the charging wire stretched in this embodiment, and fig. 4 is a partial schematic view of the accommodating base. The charging stand 1 comprises a base 10, a containing stand 20, a charging cord 30 and an elastic element 40. As shown in fig. 1, the charging stand 1 in this embodiment is described by way of example in which a plurality of accommodating stands 20, charging wires 30 and elastic elements 40 are disposed on a base 10, but the invention is not limited thereto. Wherein, the number of the containing seats 20, the charging wires 30 and the elastic elements 40 are set corresponding to each other.

The housing base 20 is disposed in the base 10 as shown in fig. 1 and 2. The accommodating seat 20 includes an accommodating groove 21, a guide portion 22, and a positioning portion 23. The accommodating groove 21 is used for accommodating a rechargeable battery to be charged, and the shape of the accommodating groove 21 can be designed and changed according to the shape requirement of the rechargeable battery. The guiding portion 22 is disposed at one end of the accommodating groove 21, and in the present embodiment, is disposed at the left end of the accommodating groove 21 as viewed in the drawing. The positioning portion 23 is disposed adjacent to the guiding portion 22. The positions of the

positioning portions

22 and 23 may be determined according to the positions of the connectors of the rechargeable battery, and preferably, the side closest to the position of the connector of the rechargeable battery.

The charging cord 30 includes a power cord 31, a stopper 32, and a connector 33. The power line 31 includes a first end 311 and a second end 312. The first end 311 is received in the base 10, and the second end 312 is inserted into the guiding portion 22 of the receiving base 20, and can be pulled out or retracted along the guiding portion 22. The end of the first end 311 may be connected to a power supply or a circuit board (not shown) disposed in the base 10 to provide power required for charging. As shown in fig. 2, the stopper 32 is disposed near the first end 311 of the power line 31 and located in the base 10. The connector 33 is disposed at the end of the second end 312 of the power cord 31 and is accommodated in the positioning portion 23. The configuration of the connector 33 can be changed according to the configuration of the rechargeable battery to be charged, so as to adapt to different rechargeable batteries.

The elastic element 40 has one end passing through the power line 31 and the other end fixed to the receiving slot 21. the elastic element 40 of the present embodiment is an extension spring, when the extension spring is assembled, the elastic element 40 is slightly pulled to generate an elastic restoring force to provide a slight pulling force to the power line 31, so that the connector 33 can be further positioned at the positioning portion 23. the elastic element 40 used in the present embodiment includes two rings 41 and a spring body 42. the two rings 41 are respectively disposed at two ends of the spring body 42 in a pulling direction, and each ring 41 is perpendicular to the pulling direction of the spring body 42. when one of the two rings 41 passes through the power line 31, the right angle α between the rings 41 and the spring body 42 faces the second end 312 of the power line 31. thus, when the charging cord 30 is pulled to drive the elastic element 40 to be pulled, the spring body 42 will not be blocked to the power line 31 to affect the pulling smoothness, and the elastic element 40 is not easily damaged.

Next, how to move or reset the charging wire 30 in a certain range and position will be further described. Referring to fig. 2 and 3, the guide portion 22 includes a first opening end 221 and a second opening end 222, a side adjacent to the first opening end 222 has an oblique stopper 24, and the second opening end 222 has a U-shaped stopper 25. The inclined stopper 24 at the first opening end 222 can stop the power cord 31, so as to prevent the power cord 31 from being pulled away from the guide portion 22 during the stretching process. Moreover, the inclined stopper 24 still has a large enough opening to allow the power cord 31 to pass through in an inclined manner, so that the power cord 31 can be easily assembled or replaced.

The U-shaped stopper 25 at the second opening end 222 of the guide portion 22 provides a stopping function for the stopper 32 of the charging cable 30. As shown in fig. 3, when the charging cord 30 is pulled out, it can only be pulled up to the position where the stopper 32 is disposed, i.e. it cannot be pulled out any more due to the blocking of the U-shaped stopper 25. The stopping manner of the U-shaped stopper 25 may be that the size of the opening of the U-shaped stopper 25 is smaller than the size of the outer diameter of the stopper 32, so that the stopper 32 cannot pass through the opening of the U-shaped stopper 25 and stop.

In addition, there may be another U-shaped stop 26 at the docking portion 22 adjacent the first open end 222. And a tapered stop 34 where the power cord 31 connects to the connector 33. As can be seen from fig. 2 and 3, when the power cord 31 is pulled out and the user releases his hand to make the power cord 31 retract by the elastic restoring force provided by the elastic element 40, an instant pulling force is generated. The tapered stopper 34 at the connection position of the power cord 31 and the connector 33, in combination with the other U-shaped stopper 26 at the first open end 222, can provide a buffer between the connector 33 and the guiding portion 22 when the power cord 31 is pulled back. When the power cord 31 is retracted and restored by the elastic restoring force, it can be stopped at a specific position without being continuously pulled back into the accommodating seat 20, and the connector 33 can be prevented from directly impacting the guiding portion 22 or impacting the positioning portion 23 with a large force.

Referring to fig. 2 to 4, the positioning portion 23 includes a U-shaped groove 231, a first retaining wall 232 and a second retaining wall 233. The first retaining wall 232 and the second retaining wall 233 are disposed on two opposite sides of the U-shaped groove 231. The connector 33 of the charging cord 30 is accommodated in the U-shaped groove 231 when the connector is in a folded state (i.e., the state shown in fig. 2). The first wall 232 and the second wall 233 provide a limit function for the connector 33, so that the connector 33 is securely accommodated in the U-shaped groove 231. In other embodiments, the shape or the orientation of the U-shaped groove 231 may be changed according to the shape of the connector 33.

Furthermore, the first wall 232 has a guiding slant 234. The end of the second retaining wall 233 has an inclined surface 235 inclined toward the U-shaped groove 231. When the connector 33 is pulled back to the positioning portion 23 by the power cord 31, the connector can be guided and accommodated in the U-shaped groove 231 by the guiding inclined surface 234 of the first retaining wall 232 or the inclined surface 235 of the second retaining wall 233.

Through the structure, the charging wire 30 which can be used in a stretching way is arranged on the charging seat 1, so that the charging seat 1 can be applied more widely without being limited to the charging battery which can only be applied to a specific model, and cannot be replaced easily. Except that a plurality of sets of the containing seat 20, the charging cord 30 and the elastic element 40 can be simultaneously arranged on the base 10 of the charging seat 1 to expand the number of the rechargeable batteries which can be charged simultaneously. If it is necessary to charge the charging battery of a different connector 33, the charging cord 30 may be replaced with a charging cord 30 having an appropriate connector 33. Furthermore, the elastic element 40 is used to connect the housing base 20 and the charging cord 30, so that the charging cord 30 can be stretched out of the housing base 20 when in use, and can return to the housing base 20 under the action of elastic restoring force after use. In addition, the positioning part 23 for positioning the connector 33 is disposed on the housing base 20, so that the user can easily find the connector 33 and pull out the connector for use. After the charging wire is used, the connector 33 is stretched, retracted and contained in the positioning part 23 under the action of elastic restoring force, and the trouble and trouble of picking up the charging wire 30 are avoided.

When the charging cord 30 is not used or used, as shown in fig. 2, most of the power cord 31 of the charging cord 30 is accommodated in the base 10 or the accommodating seat 20, and the connector 33 is accommodated in the positioning portion 23, so that the overall appearance is neat and beautiful. As shown in fig. 3, when the charging cord 30 is to be used, the charging cord 30 is simply pulled out to connect the connector 33 to the connector of the rechargeable battery. When in use, only the power cord 31 with the required length is pulled out, and the problem that the power cord 31 is scattered to fill a table or needs to be additionally arranged by a concentrator is avoided. After the rechargeable battery is used, the connector 33 is pulled away from the rechargeable battery, and the charging wire 30 can return to the original position under the tension of the elastic element 40 only by releasing the hand, so that the rechargeable battery does not need to be wound and collected when the rechargeable battery is used.

Although the present invention has been described with reference to the foregoing embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
