Detailed Description

It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict. The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

The embodiment of the utility model provides a charger, as shown in fig. 1-3, charger includes charger main part 1 and at least one charging mechanism 2. The charger main body 1 includes a conductive member 11 and a first power output member 12, and the first power output member 12 is electrically connected to the conductive member 11. The charging mechanism 2 comprises a power input piece 21, a data line 22 and a second power output piece 23; the data line 22 and the second power output element 23 are electrically connected to the power input element 21. The charging mechanism 2 is detachably or fixedly disposed on the charger main body 1, so that the power input member 21 of the charging mechanism 2 is connected to the first power output member 12. The charging mechanism 2 is also used for detachably mounting another charging mechanism 2, so that the power input member 21 of another charging mechanism 2 is connected with the second power output member 23 of the charging mechanism 2 mounted on the charger main body 1.

Through implementing this embodiment, when the conductive piece 11 of the charger main body 1 is connected to an external power supply piece (not shown in the figure), the first power output piece 12 electrically connected to the conductive piece 11 can obtain the electric energy, and the power input piece 21 of the charging mechanism 2 installed on the charger main body 1 is connected to the first power output piece 12 of the charger main body 1, so as to obtain the electric energy and transmit the electric energy to the data line 22, so that the data line 22 can charge the electric equipment, because the charging mechanism 2 is further provided with the second power output piece 23 for supplying power to another charging mechanism 2, when more electric equipment needs to be charged, the number of the charging mechanism 2 can be increased, for example, when two electric equipment need to be charged, one charging mechanism 2 can be added, when three electric equipment needs to be charged, three charging mechanisms 2 can be assembled, and so on. Fig. 1-3 show be equipped with two charging mechanism 2's schematic diagrams, newly-increased charging mechanism 2 installs on installing the charging mechanism 2 at charger main part 1 to make this charging mechanism 2's power input 21 and install and be connected at charger main part 1's charging mechanism 2's second power output 23, so that this charging mechanism 2's data line 22 can acquire the electric energy that carries out charging for the second consumer, from this, the utility model discloses the charger of embodiment uses more in a flexible way, and user experience is better.

Specifically, the conductive members 31 may be conductive pins for plugging into the socket 200, or may be wire mounting openings for mounting a zero-live wire (not shown), or may be a Type-C male connector, a Type-C female connector, or the like.

The connection of the power input member 21 to the first power output member 12 and the connection of the power input member 21 to the second power output member 23 in the present embodiment include direct contact type connection to electromagnetic induction type connection, and specific embodiments of the three connection methods are listed below for reference.

In one embodiment, as shown in fig. 1-2, the first power output element 12 and the second power output element 23 are both output conductive contacts 3, the power input element 21 is an input conductive contact 211, and when the charging mechanism 2 is mounted on the charger main body 1, the input conductive contact 211 of the charging mechanism 2 is in contact with the output conductive contact 3 of the charger main body 1. When the other charging mechanism 2 is mounted on the charging mechanism 2 mounted on the charger main body 1, the input conductive contact 211 of the other charging mechanism 2 is in contact with the output conductive contact 3 of the charging mechanism 2 mounted on the charger main body 1.

Specifically, the output conductive contact 3 of the charger main body 1 and the input conductive contact 211 of the charging mechanism 2 can be conducted only by contacting, and the operation is relatively easy, unlike a plug and a socket, which can be conducted by aligning and inserting the plug into the socket.

In another embodiment, as shown in fig. 1-2, the first power output element 12 and the second power output element 23 are both one of a Type-C female socket (not shown) or a Type-C male plug (not shown), and the power input element is the other one of a Type-C female socket (not shown) or a Type-C male plug (not shown).

In another embodiment, as shown in fig. 1 and 3, the first power output 12 and the second power output 23 are both wireless output coils 4, and the power input 21 is a wireless input coil 212; when the charging mechanism 2 is arranged on the charger main body 1, the wireless input coil 212 of the charging mechanism 2 and the wireless output coil 4 of the charger main body 1 are electromagnetically induced; when the other charging means 2 is mounted on the charging means 2 mounted on the charger main body 1, the wireless input coil 212 of the other charging means 2 electromagnetically induces the wireless output coil 4 of the charging means 2 mounted on the charger main body 1.

The embodiment charges the charging mechanism 2 in a wireless charging mode, and the charging mechanism 2 is not provided with an exposed conductive structure during use, so that the charging mechanism is safer to use.

Specifically, as shown in fig. 1 to 3, since the outlet 200 usually requires ac power and the electrical device needs dc power, the charging mechanism 2 may further be provided with a rectifier module 24 to convert ac power inputted from the power input 21 into dc power, so that the data line 22 can be electrically connected to the power input 21 through the rectifier module 24 to charge the electrical device with dc power.

Further, as shown in fig. 1 to 3, the voltage in the socket 200 is generally higher than the voltage required for charging the electric device, and in order to normally charge the electric device, the charger main body may further include a transforming module 13. Since the transformer module 13 can convert the high-voltage ac power into the low-voltage ac power, the first power output element 12 can output the low-voltage ac power to the charging mechanism 2 as long as the first power output element 12 is connected to the conductive element 11 through the transformer module 13.

In the embodiment, the charger main body 1 is provided with a first magnetic member (not shown in the figure), and the charging mechanism 2 is provided with a second magnetic member (not shown in the figure) and a third magnetic member (not shown in the figure); when the charging mechanism 2 is arranged on the charger main body 1, the second magnetic part and the first magnetic part are adsorbed; when the other charging mechanism 2 is mounted on the charging mechanism 2 mounted on the charger main body 1, the second magnetic member of the other charging mechanism 2 is attracted to the third magnetic member of the charging mechanism 2 mounted on the charger main body 1.

In this embodiment, when the charging mechanism 2 is installed on the charger main body 1, the second magnetic member and the first magnetic member are attracted to each other, so that the charging mechanism 2 can be prevented from falling off from the charger main body 1, and the stability of the charger in use is improved. Similarly, when one charging mechanism 2 is installed on the other charging mechanism 2, the second magnetic part of the charging mechanism 2 is attracted to the third magnetic part of the other charging mechanism 2, so that the charging mechanism 2 can be prevented from falling off from the other charging mechanism 2, and the stability of the charger in use is improved.

Of course, besides the magnetic connection mode, a buckle connection mode and a thread connection mode can be used for connection, and the technical personnel in the field can adjust the connection modes adaptively.

In an embodiment, as shown in fig. 1-4, the charger main body 1 further includes an extension wire 14, one end of the extension wire 14 is electrically connected to the conductive member 11, and the other end is electrically connected to the first power output member 12. The extension wire 14 can extend the charging distance to satisfy the charging requirement at a long distance.

In an embodiment, as shown in fig. 1-10, the data line 22 has an input end 221 and an output end 222, the input end 221 is electrically connected to the power input device, and the output end 222 is used for connecting to an electric device; the charging mechanism 2 further includes a housing 26 and a wire takeup member 27. The housing 26 has a receiving cavity (not shown), the power input element 21, the data line 22, the second power output element 23 and the wire winding assembly 27 are all disposed in the housing 26, the accommodating cavity is provided with a fixed shaft 261, and the outer surface of the shell 26 is provided with an outlet 262 penetrating to the accommodating cavity. The wire rewinding assembly 27 comprises a rotating disc 271 and an elastic member 272, wherein a mounting hole 2711 is formed in the middle of the rotating disc 271, and the fixed shaft 261 is inserted into the mounting hole 2711, so that the rotating disc 271 can rotate around the fixed shaft 261. The turntable 271 has a first side (not shown) and a second side (not shown) opposite to the first side, the surface of the turntable 271 is provided with a threading opening 2712, and the data line 22 is threaded through the threading opening 2712 so as to wind a wire on the first side and the second side of the turntable 271. The elastic member 272 is installed on the turntable 271 and connected to the housing 26 to store energy when the turntable 271 rotates in the forward direction and release energy when the turntable 271 rotates in the reverse direction; wherein the outlet 262 is located on the first side of the rotating disc 271, the tightness of the winding of the data line 22 on the second side is less than the tightness of the winding of the data line 22 on the first side.

Specifically, the data line 22 will be tightly wound several turns on a first side and two adjacent turns of the data line 22 are conformed; the data line 22 is loosely wound several turns on the second side with a gap between two adjacent turns of the data line 22, so that the data line 22 is wound less tightly on the second side than the data line 22 on the first side.

The charging mechanism 2 of the present embodiment has a longer service life, particularly because the data line 22 needs to pass through the threading opening 2712 of the turntable 271 when being installed inside the housing 26, which divides the data line 22 into two sections, the first section of the data line 223 tightly winds on the first side of the turntable 271, the output end 222 passes through the outlet 262 of the housing 26, the second section of the data line 224 loosely winds on the second side of the turntable 271, and the input end 221 is connected with the power input member 21. Since the first segment of data line 223 is tightly wound, when the output end 222 is pulled, a force acts on the turntable 271 and drives the turntable 271 to rotate, in the process, the part of the first segment of data line 223 that is not pulled out rotates with the turntable 271 as a whole, but since the winding of the second segment of data line 224 on the second side of the turntable 271 is loose, the second segment of data line 224 is further wound only in the process of pulling out the first segment of data line 223, that is, the number of winding turns is increased to make the winding become tighter, and the winding does not rotate with the turntable 271 as a whole as the first segment of data line 223, so the end of the second segment of data line 224 can be relatively stationary with the power input member 21 in the process, and does not rotate with the turntable 271, and therefore, wear due to friction is avoided, and the charging mechanism 2 of the present embodiment has a longer service life.

In this embodiment, when the first segment of data line 223 is pulled out, the rotation direction (X direction in fig. 9) of the rotating disc 271 is positive, the elastic member 272 is charged with energy, and the second segment of data line 224 is only wound further, i.e. the number of windings is increased, so that the windings become tighter. When the elastic member 272 releases the energy, the rotation direction (Y direction in fig. 9) of the rotating disc 271 is reversed, and at this time, the pulled first segment of the data wire 223 can be retracted into the housing 26, and the winding number of the second segment of the data wire 224 can be reduced to restore the original loose state.

In an embodiment, as shown in fig. 1 to 10, a card line structure 2713 is disposed on the second side of the rotating plate 271, the card line structure 2713 is used to fix the data line 22, and the distance between the card line structure 2713 and the mounting hole 2711 is smaller than the distance between the threading opening 2712 and the mounting hole 2711.

Specifically, when the wire clamping structure 2713 is not provided, if the user continues to pull the data wire 22 when the first data wire 223 is completely pulled out, the second data wire 224 is pulled from the second side of the rotary plate 271 to the first side of the rotary plate 271 through the wire threading opening 2712, in this case, the elastic member 272 cannot return the second data wire 224 when releasing energy, and the first data wire 223 cannot be completely retracted into the casing 26, and the casing 26 needs to be disassembled to rewind to recover normal use, so that the user experience is poor. To avoid this, the embodiment provides a wire clip structure 2713 on the second side of the turntable 271, and the wire clip structure 2713 can fix the second segment of data wire 224 so that it cannot be pulled by the user from the second side of the turntable 271 to the first side of the turntable 271. Since the second data line 224 is wound around the mounting hole 2711, the distance between the wire clamping structure 2713 and the mounting hole 2711 is smaller than the distance between the wire threading opening 2712 and the mounting hole 2711 in this embodiment, so that the winding can be performed after the second data line 224 is fixed.

In an embodiment, as shown in fig. 1 to 10, the wire-clamping structure 2713 is an "L" -shaped clamping block, and when the "L" -shaped clamping block is disposed on the rotating disc 271, the "L" -shaped clamping block and the surface of the rotating disc 271 enclose a wire-clamping space (not shown in the figure) together, and only the second segment of the data wire 224 needs to be forcibly clamped into the wire-clamping space.

Of course, it is understood that besides the embodiment of the "L" shaped latch, the second data line 224 may be fixed by glue or other methods, as long as the second data line 224 is prevented from being pulled by the user from the second side of the turntable 271 to the first side of the turntable 271, and the embodiment is not limited thereto, and those skilled in the art can adjust this.

In an embodiment, as shown in fig. 1-10, a protruding rib 2714 is disposed on the second side of the rotary plate 271, and the protruding height of the protruding rib 2714 is flush with or higher than the "L" -shaped latch.

Specifically, the second segment of data line 224 is wound on the protruding rib 2714, and since the protruding height of the protruding rib 2714 is flush with or higher than the L-shaped fixture block, the second segment of data line 224 cannot be wound on the L-shaped fixture block during winding, the winding is more natural, and the L-shaped fixture block cannot abut against the winding part of the second segment of data line 224 during forward rotation and reverse rotation of the turntable 271.

To facilitate winding, in the embodiment, as shown in fig. 1-10, the second side of the rotating plate 271 is provided with a winding post 2715, and the winding post 2715 is spaced apart from the mounting hole 2711 to form a threading space (not shown) therebetween, so that the data cable 22 can be wound around the fixing shaft 261 through the threading space.

In one embodiment, as shown in fig. 1-11, elastic member 272 is a clockwork spring; a through groove 2611 is provided on the fixed shaft 261 in the radial direction of the fixed shaft 261, one end of the spiral spring is mounted on the through groove 2611, the rotary plate 271 is further provided with a protrusion 2716 spaced from the mounting hole 2711, and the other end of the spiral spring is mounted on the protrusion 2716. Therefore, when the rotating disc 271 rotates in the forward direction, the clockwork spring is fixedly arranged at one end of the through groove 2611, and the end arranged on the protrusion 2716 rotates along with the rotating disc 271, so that energy is stored.

Specifically, the spiral spring is a spring formed by winding a material into a planar spiral shape, one end of the spring is fixed, and after a torque is applied to the other end of the spring, the material is subjected to bending moment to generate bending elastic deformation, so that the spring generates torsion on the plane of the spring. The deformation angle is proportional to the torque, and has the characteristics of high torque and low fatigue.

To avoid that the elastic member 272 releases energy to drive the turntable 271 to rotate reversely when the data cable 22 is used, two embodiments are listed below for reference.

In one embodiment, a wire clamping assembly (not shown) is installed at the outlet 262, and after the data wire 22 is pulled out from the outlet 262, the wire clamping assembly can be adjusted to narrow the outlet 262 until the data wire 22 at the outlet 262 is clamped, at this time, since the data wire 22 is clamped and the data wire 22 passing through the outlet 262 cannot retract into the housing 26, the rotating disc 271 cannot rotate reversely, and the elastic member 272 is naturally limited and cannot release energy. When the data line 22 needs to be retracted, the wire clamping assembly is adjusted again to enlarge the wire outlet 262, and the elastic member 272 drives the rotating disc 271 to rotate reversely after the wire clamping assembly is disengaged from the wire clamping relationship, so that the data line 22 is retracted.

In another embodiment, as shown in fig. 1 to 14, the casing 26 includes a first casing 263 and a second casing 264 covering the first casing 263, and the accommodating cavity is enclosed by the first casing 263 and the second casing 264. A strip-shaped blind hole 2641 is formed in one side, facing the accommodating cavity, of the second shell 264; a lock plate 273 and a lock ball 274 are also included. The locking plate 273 is installed in the one side that the carousel 271 is close to bar blind hole 2641, and concave rail 2731 has been seted up towards one side of bar blind hole 2641 to the locking plate 273, and concave rail 2731 has locking position 27311. The locking balls 274 are partially received in the groove track 2731 and the blind strip-shaped hole 2641 and can move along the groove track 2731 when the turntable 271 rotates in the forward or reverse direction. When the locking ball 274 moves to the locking position 27311, the concave track 2731 can be engaged with the strip-shaped blind hole 2641 through the locking ball 274 to limit the release of the elastic member 272.

In the wire rewinding assembly 27 of this embodiment, a portion of the locking ball 274 is received in the blind strip hole 2641, and another portion of the blind protruding hole 2641 is received in the concave track 2731, and the locking plate 273 is mounted on the rotating disc 271, so that when the rotating disc 271 rotates in the forward or reverse direction, the concave track 2731 rotates along with the blind strip hole 2641, and the moving path of the locking ball 274 is restricted by the blind strip hole 2641, so that when the concave track 2731 rotates, the locking ball 274 does not rotate along with the concave track 2731, and only the position of the locking ball 274 on the concave track 2731 is changed. When the concave track 2731 rotates until the locking ball 274 is located at the locking position 27311, the concave track 2731 and the blind strip-shaped hole 2641 can provide a reverse acting force for the locking ball 274, so as to limit the rotation of the concave track 2731, and the elastic member 272 cannot release energy.

To achieve the above object, the groove track 2731 may refer to the following arrangement. In a particular embodiment, as shown in fig. 1-14, the groove track 2731 includes an inner ring track 27312, an outer ring track 27313, a lock track 27314, and a third connection track 27315. The outer track 27313 is disposed around the inner track 27312, the outer track 27313 includes a first outer track 273131 and a second outer track 273132, the first outer track 273131 has a first end 273133 and a second end 273134 disposed along a length direction thereof, a distance between the first end 273133 and a center of the turntable 271 is smaller than a distance between the second end 273134 and the center of the turntable 271, and two ends of the second outer track 273132 are respectively connected to the first end 273133 and the second end 273134. The locking track 27314 includes a locking position 27311, a first connecting track 273141 and a second connecting track 273142, the locking position 27311 is located between the outer ring track 27313 and the inner ring track 27312, one end of the first connecting track 273141 is connected to the locking position 27311, and the other end is connected to a connection position between the second outer track 273132 and the first end 273133, so as to guide the locking ball 274 into the locking position 27311 through the first end 273133 when the elastic member 272 is released; the second connecting rail 273142 has one end connected to the locking position 27311 and the other end connected to the inner rail 27312 to guide the locking ball 274 at the locking position 27311 into the inner rail 27312 when the elastic member 272 is charged. The third connecting rail 27315 serves to connect the inner rail 27312 and the first outer rail 273131 to guide the locking balls 274, located at the connection position of the inner rail 27312 and the third connecting rail 27315, into the first outer rail 273131 when the elastic member 272 is charged.

Further, as shown in fig. 1-14, in order to limit the release of the elastic member 272, the locking ball 274 enters the second outer rail 273132 through the first end 273133, and the second outer rail 273132 is recessed less than the first end 273133. In order to limit the energy storage of the elastic member 272, the locking ball 274 enters the first connection rail 273141 through the locking position 27311, and the first connection rail 273141 is recessed less than the inner ring rail 27312. In order to limit the release of the elastic member 272, the locking ball 274 enters the second connection rail 273142 through the inner ring rail 27312, and the second connection rail 273142 of this embodiment is recessed less than the inner ring rail 27312. In order for the elastic member 272 to be discharged, the locking ball 274 enters the third connection rail 27315 through the first outer rail 273131, and the third connection rail 27315 is recessed less than the first outer rail 273131.

In the present embodiment, the data line 22 can be extended in multiple steps without scratching the surface of the data line 22, and the design is very ingenious, referring to fig. 1 and 14, when the data line 22 is not stretched, the latching ball 274 is located at the connection position of the inner track 27312 and the third connection track 27315, and when the data line 22 is stretched, the concave track 2731 rotates along the direction M in fig. 13, so that the latching ball 274 enters the first outer track 273131 through the second outer track 273132, at this time, the data line 22 is released, the elastic element 272 releases energy, so as to drive the concave track 2731 to rotate along the direction Z in fig. 13, since the degree of depression of the second outer track 273132 is smaller than that of the first end 273133, the latching ball 274 does not enter the second outer track 273132 through the first end 273133, but enters the first connection track 3141 through the first end 273133, and then enters the latching position 27311, and when the latching ball 274 is located in the latching position 27311, the concave track 2731 and the strip-shaped 272641 can provide a reverse acting force for the latching ball 274 to limit the latching ball to prevent the concave track 2731 from rotating, so as to prevent the elastic element 27272.

When the data line 22 is found to be not long enough, the data line 22 may be stretched again, so as to drive the concave track 2731 to rotate along the direction M in fig. 13, because the concave degree of the first connection track 273141 is smaller than the locking position 27311, the locking ball 274 will not enter the first connection track 273141, but will enter the second connection track 273142, and then enter the first outer track 273131 along the inner track 27312 and the third connection track 27315, at this time, the data line 22 is continuously stretched until the locking ball 274 enters the first outer track 273131 through the second outer track 273132, and then the data line 22 is released, and the elastic member 272 releases energy, so as to drive the concave track 2731 to rotate along the direction Z in fig. 13, so that the locking ball 274 enters the locking position 27311, and thus the pulled data line 22 can be extended.

When the data line 22 needs to be retracted, the data line 22 needs to be pulled slightly, so as to drive the concave track 2731 to rotate along the direction M in fig. 14 until the locking ball 274 passes through the second connecting track 273142 and enters the inner track 27312, and at this time, the data line 22 is released, the elastic element 272 releases energy, so as to drive the concave track 2731 to rotate along the direction Z in fig. 14, and since the degree of concavity of the second connecting track 273142 is smaller than that of the inner track 27312, the locking ball 274 can rotate in the inner track 27312 until the data line 22 is fully retracted.

In order to prevent a user from releasing the data wire 22 when the locking ball 274 is located on the second outer rail 273132, which may cause the locking ball 274 to enter the third connection rail 27315, the third connection rail 27315 may be recessed less than the first outer rail 273131 to limit the entry of the locking ball 274 into the third connection rail 27315 via the first outer rail 273131 when the elastic member 272 is released.

Of course, the degree of concavity referred to in this embodiment refers to a degree of local concavity, not an overall concavity, for example, the degree of concavity of the second outer rail 273132 is smaller than that of the first end 273133, refers to the degree of concavity of the connection location of the second outer rail 273132 and the first end 273133, and is smaller than that of the connection location of the first end 273133 and the second outer rail 273132. Thus, the locking balls 274 cannot move to the position where the second outer rail 273132 is connected to the first end 273133 through the position where the first end 273133 is connected to the second outer rail 273132.
