Description

Technical Field

[0001] The present invention relates to the technical field of mobile power supplies, and in particular to a power bank that is convenient to connect with a charging device. Background Art

[0002] A power bank is a mobile power source that can charge electronic products such as mobile phones and tablets. Nowadays, the use of mobile phones is becoming more and more popular, and the increase in mobile phone functions has made everyone inseparable from mobile phones. However, mobile phones have low battery capacity and fast power consumption, and they often need to be charged. When people go out and cannot find a socket to charge, a power bank can be used as a mobile power source to charge their mobile phones at any time.

[0003] The existing power banks are divided into two categories: power banks with built-in wires and power banks with external wires. No matter whether they are power banks with built-in wires or external wires, they all use data cables to charge mobile phones. As consumables, data cables are often damaged during use, especially the wiring ports connected to mobile phones. Because most people like to play with their mobile phones while charging, the wiring ports will move with the mobile phones, resulting in bending of the wires near the wiring ports. After the wiring ports are used for a long time, the swing of the wiring harness will cause the interface to loosen, thereby exposing the wiring harness inside the data cable. If they continue to be used, there will be safety hazards. Therefore, people need to use devices such as protective covers to protect the wiring ports, especially power banks with built-in wires, whose data cables cannot be replaced. Such power banks need to protect the data cables more. Therefore, a power bank that can effectively protect the wiring ports of the data cables and is convenient for connecting to charging devices is designed. Summary of the invention

[0033] See also Figure 2 The fixing assembly includes a first guide rail 12, which is fixedly connected to the middle of the power bank 1. Two clamping members 11 are slidably connected to the first guide rail 12. The upper parts of the clamping members 11 are each provided with an inclined surface. A first spring 13 is fixedly connected between the two clamping members 11.

[0034] See also Figure 4-Figure 5 , and also includes two rope wheels 18, which are rotatably connected to the front and rear sides of the left part of the protective member 15 respectively.

[0035] See also Figure 4-Figure 5 , and also includes two pull ropes 17, one end of the pull rope 17 is fixedly connected to the right part of different moving parts 19, and the other end of the pull rope 17 is passed around the rope wheel 18 and fixedly connected to the corresponding closing part 16.

[0036] When people's mobile phones are low on power and need to be charged but cannot find a socket to charge, people can use the device. First, people clamp the mobile phone between the two clamping members 11, and the first spring 13 is stretched. Under the action of the first spring 13, the mobile phone is clamped in the middle by the clamping member 11, thereby preventing the mobile phone from falling out. At the same time, the inclined surface on the upper part of the clamping member 11 is squeezed and matched with the mobile phone, so that the mobile phone can better separate the clamping member 11. Then people hold the USB interface of the charging cable 101 and move it to the left. The USB interface of the charging cable 101 drives the second guide rail 110 and then drives the moving member 19 to move to the left, so that the moving member 19 is squeezed and matched with the baffle 14. The moving member 19 squeezed by the baffle 14 is relative to the charging The USB interface of the charging cable 101 moves to the right, the second spring 111 is compressed, the moving member 19 pulls the rope wheel 18 to the right, so that the rope wheel 18 drives the closing member 16 to rotate toward the side away from each other, the first torsion spring 151 is twisted, and when the closing member 16 rotates 90 degrees, the closing member 16 is blocked by the moving member 19 and cannot continue to rotate toward the side away from each other, the moving member 19 continues to move to the right, so that the moving member 19 drives the pull rope 17 and then drives the closing member 16 to continue to move to the right, the closing member 16 drives the protective member 15 to move to the right, so that the charging cable 101 can be extended, and the USB interface of the charging cable 101 continues to move to the left through the opening on the baffle 14 and is connected to the charging port of the mobile phone, so that The power bank 1 charges the mobile phone through the charging cable 101. When the mobile phone is fully charged, people manually pull out the USB interface of the charging cable 101 to the right, and the USB interface of the charging cable 101 drives the second guide rail 110 and then drives the moving member 19 to move to the right. When the moving member 19 is separated from the baffle 14, the second spring 111 resets and drives the moving member 19 to move to the left and reset. The moving member 19 drives the pull rope 17 and then drives the closing member 16 to move to the left and reset. The closing member 16 drives the protective member 15 to move to the left and reset. The moving member 19 no longer pulls the pull rope 17 to the right. The first torsion spring 151 resets and drives the closing member 16 to rotate and reset toward the side close to each other. When the power bank 1 is not charging the mobile phone, The closure member 16 is in a closed state, and under the action of the first torsion spring 151, the closure member 16 will not be easily opened. Under the protective action of the closure member 16 and the protective member 15, the USB interface of the charging cable 101 can be protected, thereby preventing the USB interface of the charging cable 101 from being damaged when not in use. When the mobile phone is to be charged, the baffle 14 will squeeze the moving member 19, so that the moving member 19 pulls the pull rope 17 to the right, so that the pull rope 17 drives the closure member 16 to rotate toward the side away from each other, and the charging cable 101 is extended to charge the mobile phone. By setting the closure member 16 and the protective member 15, the USB interface of the charging cable 101 can be protected from being damaged when not in use.

[0037] Example 2: Based on Example 1, please refer to Figure 6-Figure 7 , and also includes a stabilizing mechanism that can assist in positioning the charging cable 101 when the charging cable 101 is connected to the mobile phone, and stabilize the connection between the mobile phone and the USB interface of the charging cable 101 after the connection to prevent damage to the USB interface of the charging cable 101 due to external force. The stabilizing mechanism includes two second fixing members 222, and the second fixing members 222 are fixedly connected to the side of the baffle 14 close to the protective member 15. The second fixing members 222 are rotatably connected to the sides close to each other with screws 25, and the screws 25 are threadedly connected to the connecting frame 24. The screws 25 are fixedly connected to the sides close to each other with gears 26, and a rotating member 27 is fixedly connected between the gears 26. Two protrusions are provided on the side of the rotating member 27 away from the gear 26. A rubber block 28 is fixedly connected to the side of the rotating member 27 close to the baffle 14, and the rubber block 28 is snap-fitted with the baffle 14. The baffle 14 is connected with a clamping component that can clamp the USB interface of the charging cable 101.

[0038] See also Figure 6-Figure 7 , and further includes a bottom plate 2, which is fixedly connected to one side of the baffle 14 close to the protective member 15, and a slope is arranged on the right side of the bottom plate 2.

[0039] See also Figure 6-Figure 7 , and also includes two racks 29, which are fixedly connected to the upper left sides of different moving members 19, and the gears 26 are meshed with the corresponding racks 29.

[0040] See also Figure 6-Figure 7 The clamping assembly includes two first fixing members 221, which are fixedly connected to the right side of the baffle 14. The first fixing members 221 are respectively located at the front and rear sides of the opening on the baffle 14. The sides of the first fixing members 221 that are close to each other are fixedly connected with the fourth guide rail 22. The fourth guide rail 22 and the corresponding connecting frame 24 are slidably connected. The sides of the fourth guide rail 22 that are close to each other are slidably connected with the positioning member 21, and the third spring 23 is fixedly connected between the positioning member 21 and the connecting frame 24. The sides of the positioning members 21 that are close to each other are provided with grooves, which are engaged with the corresponding moving member 19.

[0041] When people are in a dark place but want to charge their mobile phones, the USB interface of the charging cable 101 cannot be connected to the charging port of the mobile phone at one time. Therefore, a stabilizing mechanism is provided to assist in positioning the charging cable 101 when the USB interface of the charging cable 101 is connected to the mobile phone, and to stabilize the connection between the mobile phone and the USB interface of the charging cable 101 after the connection to prevent the USB interface of the charging cable 101 from being damaged due to external force. The working principle is as follows: when people want to charge, they hold the USB interface of the charging cable 101 and move it to the left towards the charging port of the mobile phone. The right side of the bottom plate 2 is provided with an inclined surface, which can prevent the protective member 15 from being blocked by the right side of the bottom plate 2. The USB interface of the charging cable 101 The interface drives the moving part 19 and then drives the rack 29 to move to the left. The rack 29 and the gear 26 are meshed, so that the gear 26 rotates clockwise. Because the length of the rack 29 is greater than the width of the gear 26 teeth, even if the position of the USB interface of the charging cable 101 is offset, the rack 29 and the gear 26 can mesh with each other in place, and the gear 26 drives the rotating part 27 to rotate clockwise. The rotating part 27 drives the rubber block 28 to rotate clockwise, so that the rubber block 28 is separated from the rotating part 27. The material of the rubber block 28 is rubber, so that there is a large friction between the rubber block 28 and the baffle 14. When the mobile phone is not charging, the rubber block 28 can prevent the rotating part 27 from rotating due to slight vibration. The gear 26 drives the screw 25 to rotate clockwise. The screw 25 rotates clockwise, and the screw 25 is threadedly connected to the connecting frame 24. The screw 25 rotates clockwise to drive the connecting frame 24 to move toward the side close to each other. The third spring 23 is compressed, and the third spring 23 resets to drive the positioning member 21 to move toward the side close to each other, so that the positioning member 21 clamps the protective member 15 in the middle. The positioning member 21 is provided with a groove on the side close to each other, and the groove can cooperate with the moving member 19 to assist in better positioning of the USB interface of the charging cable 101, so that the USB interface of the charging cable 101 is facing the charging port of the mobile phone, thereby preventing the USB interface of the charging cable 101 from deflecting when connected to the charging port of the mobile phone, and aligning the USB interface of the charging cable 101 with the charging port of the mobile phone, thereby achieving charging. The USB interface of the wire 101 plays the role of auxiliary positioning, and the rotating member 27 rotates clockwise from the vertical state to the horizontal state, so that the rotating member 27 can be combined with the positioning member 21, and plays a protective role on the USB interface of the charging line 101 when the mobile phone is charging, thereby preventing the USB interface of the charging line 101 from being damaged. When the mobile phone is fully charged, people manually pull the USB interface of the charging line 101 to the right, and the USB interface of the charging line 101 drives the moving member 19 and then drives the rack 29 to move to the right. The rack 29 is meshed with the gear 26, so that the gear 26 rotates counterclockwise, and the gear 26 drives the rotating member 27 to rotate counterclockwise and reset, and the rotating member 27 drives the rubber block 28 to rotate counterclockwise and reset.The rubber block 28 is re-engaged with the baffle 14, and the gear 26 drives the screw 25 to rotate counterclockwise to reset, so that the connecting frame 24 moves to the side away from each other and resets, and the connecting frame 24 drives the third spring 23 and then drives the positioning member 21 to move to the side away from each other and reset, and the positioning member 21 releases the clamping effect on the protective member 15. The above operation is carried out through the meshing of the rack 29 and the gear 26, so that when the rack 29 moves to the left, the gear 26 rotates clockwise, and the gear 26 drives the rotating member 27 to rotate clockwise, and the gear 2 6 drives the screw rod 25 to rotate clockwise, so that the connecting frame 24 drives the third spring 23 and then drives the positioning member 21 to move toward the side close to each other. The positioning member 21 can clamp the protection member 15 in the middle, thereby achieving the function of auxiliary positioning of the USB interface of the charging cable 101. At the same time, under the protection of the positioning member 21 and the rotating member 27, the power bank 1 protects the interface of the charging cable 101 when charging the mobile phone through the charging cable 101, thereby preventing the USB interface of the charging cable 101 from being damaged.

[0042] See also Figure 8 , and also includes a protective mechanism that can protect the USB interface of the charging cable 101 to prevent damage due to bending and twisting. The protective mechanism includes a protective member 3, which is fixedly connected to the USB interface of the charging cable 101. A connecting member 32 is fixedly connected to the USB interface of the charging cable 101, and a second torsion spring 31 is fixedly connected between the connecting member 32 and the protective member 3.

[0043] Because the charging cable 101 is easily bent and twisted in daily life, the USB interface of the charging cable 101 will be damaged over time. Therefore, a protective mechanism is provided to protect the USB interface of the charging cable 101 to prevent damage due to bending and twisting. The following is its working principle: a protective member 3 is fixed to the USB interface of the charging cable 101. When the charging cable 101 is bent, the protective member 3 can prevent the interface from bending, thereby preventing the USB interface of the charging cable 101 from being damaged due to bending, thereby preventing the wiring harness inside the charging cable 101 from being exposed. When the charging cable 101 is twisted, a second torsion spring 31 is provided at the USB interface of the charging cable 101. The second torsion spring 31 can absorb and store the energy by deforming. The torsional force exerted on the charging cable 101, when the charging cable 101 is no longer torsionally exerted, the second torsion spring 31 will reset, and the second torsion spring 31 absorbs the torsional force exerted on the charging cable 101, thereby reducing the torsional force of the charging cable 101 itself, thereby reducing the damaging effect of the torsional force on the charging cable 101, and can avoid damage to the charging cable 101 due to torsion as much as possible, and can extend the service life of the charging cable 101. The above operation can prevent bending at the USB interface of the charging cable 101 and avoid exposure of the wiring harness inside the charging cable 101 by setting the protective member 3. By setting the second torsion spring 31, the torsional force exerted on the charging cable 101 can be absorbed and stored, thereby reducing the torsional force of the charging cable 101 itself, thereby protecting the charging cable 101 and extending the service life of the charging cable 101.

[0044] See also Figure 9-11 , and also includes a fixing mechanism that can fix the charging cable 101 when charging the mobile phone, the fixing mechanism includes a fixing block 4, the fixing block 4 is fixedly connected to the upper side of the protective member 3, the fixing block 4 is fixedly connected to the USB interface of the charging cable 101, a sixth guide rail 44 is fixedly connected to the upper part of the fixing block 4, a third fixing member 43 is slidably connected to the sixth guide rail 44, an inclined surface is provided on the upper left side of the third fixing member 43, and an inclined surface is also provided on the upper right side of the third fixing member 43, the inclined surface on the left side is pressed and matched with the rotating member 27, a fourth spring 45 is fixedly connected between the third fixing member 43 and the fixing block 4, two fifth guide rails 41 are fixedly connected to the fixing block 4, an extrusion member 42 is slidably connected between the fifth guide rails 41, and the extrusion member 42 is pressed and matched with the inclined surface on the right side of the third fixing member 43.

[0045] In order to further protect the charging cable 101, a fixing mechanism is provided to fix the charging cable 101 when charging the mobile phone. The working principle is as follows: when people want to charge the mobile phone, the USB interface of the charging cable 101 drives the second guide rail 110 and then drives the moving parts 19 to move to the left, the moving parts 19 drive the racks 29 to move to the left, the racks 29 and the gears 26 are meshed, so that the gears 26 rotate clockwise, the gears 26 drive the rotating parts 27 to rotate clockwise, and the protrusions on the rotating parts 27 are squeezed and contacted with the inclined surface of the left part of the third fixing part 43, so that the third fixing part 43 is squeezed and moved to the right. , the fourth spring 45 is compressed. When the rotating member 27 is disengaged from the inclined surface on the left side of the third fixing member 43, the fourth spring 45 is reset to drive the third fixing member 43 to move to the left and reset. Then the third fixing member 43 will block the rotating member 27, and the protrusion on the rotating member 27 will also block the protective member 15, thereby preventing the charging cable 101 from sliding out to the right when the mobile phone is charged. When the mobile phone is fully charged, people hold the squeezing member 42 and the protective member 3 in their hands and press the squeezing member 42 downward, so that the squeezing member 42 squeezes the inclined surface on the right side of the third fixing member 43 downward, so that the third fixing member 43 is squeezed and moves to the right, and the fourth spring 45 is compressed. , the third fixing member 43 no longer resists the rotating member 27, the charging cable 101 drives the moving member 19 and then drives the rack 29 to move to the right, the rack 29 is meshed with the gear 26, so that the gear 26 rotates counterclockwise, and the gear 26 drives the rotating member 27 to rotate counterclockwise to reset. When the charging cable 101 is completely pulled out of the mobile phone, people release the squeezing member 42, the third fixing member 43 is no longer squeezed by the squeezing member 42, and the fourth spring 45 resets to resist the third fixing member 43 from moving to the left to reset. At the same time, because the fixing block 4 is fixed at the position where the protective member 3 connects to the charging cable 101, when people unplug the USB interface of the charging cable 101 again, it will not be due to excessive force. The USB interface of the charging cable 101 is separated from the protective member 3 due to the large force, thereby exposing the wiring harness inside the charging cable 101. The above operation is performed by setting the third fixing member 43, so that when the mobile phone is charged, the third fixing member 43 can block the rotating member 27, and the protrusion on the rotating member 27 can block the protective member 15, thereby preventing the USB interface of the charging cable 101 from falling out during the charging process. By setting the fixing block 4, when people pull out the USB interface of the charging cable 101 again, the USB interface of the charging cable 101 will not be separated from the protective member 3 due to excessive force, thereby exposing the wiring harness inside the charging cable 101.

[0046] It should be understood that the above description is only for exemplary purposes and is not meant to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will be included within the scope of the claims herein.
