DETAILED DESCRIPTION

[0041] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0042] like Figures 1 to 7 As shown, a mobile power supply for safely replacing battery cells provided by the present invention comprises a shell 1, a battery cell 2 and a control module 3 both arranged in the shell 1, the battery cell 2 and the control module 3 are electrically connected, the bottom of the shell 1 has an opening, the shell 1 is slidably connected to a sliding cover 6 for covering the opening, the sliding cover 6 is provided with a first power connection structure 4 for conducting electricity with the battery cell 2, and one side of the opening is provided with a second power connection structure 5 for electrically conducting with the power connection structure; when the sliding cover 6 slides relative to the shell 1 to cause the first power connection structure 4 to be separated from the second power connection structure 5, the battery cell 2 is in an open circuit state;

[0043] The housing 1 is provided with a receiving slot 11 for accommodating the electronic device, and a plug module 12 for charging the electronic device is provided in the receiving slot 11 .

[0044] The present invention is mainly used for charging small electronic devices such as mobile phones. When charging, the electronic device is slid into the receiving slot 11 and the plug module 12 is inserted into the electronic device. The control module controls the battery cell 2 and the plug module 12 to be energized because the plug module 12 is sensed to be inserted into the electronic device, so that the battery cell 2 can smoothly charge the electronic device in the receiving slot 11. When the total power of the battery cell 2 decreases due to frequent use, for example, when it decreases to 50% of the initial total power, the control module 3 will notify the user, and the user will replace the battery cell 2 this year. Specifically, the user controls the sliding cover 6 to slide relative to the shell 1 to open the opening of the shell 1. When the sliding cover 6 slides, the first power connection structure 4 is separated from the second power connection structure 5, so that the battery cell 2 is disconnected from the control module 3, the plug module 12 and other power structures, that is, the battery cell 2 is in an open circuit state. At this time, when the user takes out the battery cell 2, there will be no electric shock due to the release of electric energy by the battery cell 2, thereby ensuring the safety of the user.

[0045] In this embodiment, the control module 3 includes a control chip 31, a coulomb counter 32, a display structure 33 and a contact switch 34. The display structure 33, the contact switch 34, the coulomb counter 32, the first power connection structure 4 and the plug module 12 are all electrically connected to the control chip 31. The control chip 31 is used to perform the following steps:

[0046] The first power connection structure 4 is electrically connected to the battery cell 2, and the coulomb meter 32 is used to sense the current remaining power of the battery cell 2 and display it digitally;

[0047] The plug module 12 is electrically connected to external electronic devices, and the battery cell 2 is used to charge the external electronic devices;

[0048] The state of the battery cell 2 is sensed by the contact switch 34 , and the battery cell 2 is controlled to be disconnected when the state of the battery cell 2 is abnormal.

[0049] In actual use, the above three steps can be executed simultaneously, so that the control module 3 can monitor the power of the battery cell 2, control the battery cell 2 to charge external electronic devices, and disconnect the battery cell 2 when it bulges.

[0050] The coulomb meter 32 is a device that can accurately monitor the power of the battery cell 2. Currently, Apple mobile phones have used it. The present invention applies the coulomb meter 32 to monitor the battery cell 2, so that the power of the battery cell 2 can be reliably monitored, ensuring that the user can obtain the current power of the battery cell 2 and when the total power decays to a lower level in time.

[0051] The contact switch 34 is a commonly used component that causes a signal change when touched. When the battery cell 2 (preferably a soft-pack lithium battery) bulges, the battery cell 2 contacts the contact switch 34 due to the collision and is forced to deform. The signal transmitted from the contact switch 34 to the control chip 31 will change. At this time, the control chip 31 determines that the battery cell 2 has a bulging abnormality, that is, it controls the battery cell 2 to be disconnected to avoid accidents caused by the explosion of the battery cell 2, thereby improving safety.

[0052] In this embodiment, the control chip 31 senses the current remaining power of the battery cell 2 through the coulomb meter 32 and displays it digitally, specifically including:

[0053] The coulomb meter 32 is electrically connected to the battery cell 2, and the coulomb meter 32 senses the current power of the battery cell 2 and displays it, and transmits it to the control chip 31 at the same time, and the control chip 31 controls the display structure 33 to emit light in the first light color;

[0054] When charging the battery cell 2, whenever the battery cell 2 is charged to the maximum, the coulomb counter 32 obtains the value of the maximum power and transmits it to the control chip 31, and the control chip 31 compares the value of the maximum power with the preset first power value and the second power value; wherein the value of the first power value is greater than the value of the second power value;

[0055] If the maximum power of the battery cell 2 is less than the first power value and greater than the second power value, the control chip 31 controls the display structure 33 to emit light in the second light color;

[0056] If the maximum power of the battery cell 2 is less than the second power value, the control chip 31 controls the display structure 33 to emit light with a third light color.

[0057] In actual use, taking the initial maximum power of 10000mAh as an example, the first power value is 8000mAh and the second power value is 5000mAh; the display structure 33 is a conventional color-changing LED light, for example, the first light color is white, the second light color is yellow, and the third light color is red. That is, when the battery cell 2 is fully charged, the coulomb meter 32 will sense its maximum charge. If the maximum charge of the battery cell 2 is above 8000mAh, the battery cell 2 is healthy, and the display structure 33 emits a white light when the battery cell 2 is supplying power to the outside / being charged; if the maximum charge of the battery cell 2 decays to below 8000mAh, for example, to 7800mAh, the battery cell 2 is in a sub-healthy state, and the control chip 31 controls the display structure 33 to emit a yellow light when the battery cell 2 is subsequently activated; similarly, when the maximum charge of the battery cell 2 decays to below 5000mAh, the battery cell 2 is in an unhealthy state. At this time, the control chip 31 controls the display structure 33 to emit a red light to remind the user that the battery cell 2 needs to be replaced to avoid affecting the user experience due to the small capacity of the battery cell 2.

[0058] In this embodiment, the plug module 12 includes a socket 121, a plug post 122, a first connector 123, and a second connector. The socket 121 is disposed in the housing 1 and is electrically connected to the battery cell 2. The plug post 122 is rotatably disposed in the housing 1 and plugged into the socket 121. The first connector 123 and the second connector are both disposed on the side of the plug post 122. The first connector 123 or the second connector is driven upward and located in the receiving groove 11 by controlling the rotation of the plug post 122.

[0059] The bottom of the receiving groove 11 is respectively provided with a first make way groove and a second make way groove. The first make way groove is used to accommodate the first joint 123 when the second joint is located in the receiving groove 11, and the second make way groove is used to accommodate the second joint when the first joint 123 is located in the receiving groove 11.

[0060] Currently, the commonly used connectors are mainly TYPE-C and Lighting connectors. Therefore, in the present invention, the first connector 123 can be set as a TYPE-C connector and the second connector can be set as a Lighting connector, so that most mobile phones can be adapted.

[0061] The present invention can charge the electronic device by switching the corresponding plug into the slot 11 according to the type of the electronic device inserted into the slot 11, thereby eliminating the need for a dedicated charging cable, making the overall structure of the present invention more compact. A spring 128 can be provided in the socket 121 to ensure stable and reliable power supply between the plug 122 and the socket 121. The structure of the plug post 122 can adopt one of the two options: 1. The first connector 123 and the second connector are directly arranged on both sides of the plug post 122, that is, the plug post 122 is rotated to realize the switching between the first connector 123 and the second connector; 2. The plug post 122 includes a rotating part 1221 and a power connection part 1222, the power connection part 1222 is plugged into the socket 121, the rotating part 1221 has a slot, the inner side wall of the slot has a ball 1223, and a spring 1224 is provided between the ball 1223 and the slot, so that the rotating part 1221 can achieve power connection by the contact between the ball 1223 and the power connection part 1222. When rotating, it is only necessary to rotate the rotating part 1221 to avoid deformation or even breakage of the spring piece 128 in the socket 121 due to the continuous rotation of the plug post 122.

[0062] Either of the above two structures can achieve the effect of the switching joint described in the present invention.

[0063] Specifically, a charging connector is provided at one end of the plug post 122 away from the socket 121, and a connector is provided on one side of the charging connector plug post 122, and a protective cap for covering the charging connector is connected to the connector;

[0064] The charging connector is used to connect an external charging cable.

[0065] The present invention itself can charge a mobile phone without a connecting wire. However, when it is necessary to charge a larger electronic device such as a tablet, or to charge two mobile phones at the same time, the user is required to equip an additional charging cable. By inserting the charging cable into the charging connector of the plug 122, the required electronic device can be charged through the charging cable, making the use of the present invention more flexible and more widely used. When the charging connector is not needed, the protective cap covers the charging connector to prevent external dust, water, etc. from entering the charging connector.

[0066] Specifically, the control module 3 further includes an energy storage capacitor 35 and a power switch 37. The power switch 37 is disposed between the energy storage capacitor 35 and the display structure 33. The control module 3 controls the opening and closing of the power switch 37. The control module 3 senses the state of the battery cell 2 through the contact switch 34, and controls the battery cell 2 to be disconnected when the state of the battery cell 2 is abnormal. Specifically, the control module 3 includes:

[0067] A. The control module 3 receives a signal from the contact switch 34. When the signal is a normal signal, the battery cell 2 is kept powered; if the signal is an abnormal signal, step B is executed;

[0068] B. Count the duration of the abnormal signal. If the count exceeds the preset time, it is determined that the battery cell 2 is bulging and step C is executed; if the count does not exceed the preset time, step A is executed again;

[0069] C. The control module 3 controls the battery cell 2 to stop supplying power, and controls the power switch 37 to turn on when the plug module 12 is inserted into the electronic device, and controls the display structure 33 to emit light with the third color light.

[0070] The energy storage capacitor 35 has the effect of storing a small amount of electrical energy. There are only two situations in which the battery cell 2 contacts the contact switch 34: one is that the battery cell 2 contacts the contact switch 34 due to the impact of the present invention, and the battery cell 2 will separate from the contact switch 34 after the present invention returns to rest; the other is that the battery cell 2 bulges and continues to contact the contact switch 34.

[0071] In actual use, the power switch 37 is preferably a triode or a MOS tube. In order to avoid misoperation, the present invention uses the signal duration of the contact switch 34 for discrimination, that is, when the first situation occurs, the abnormal signal of the contact switch 34 will not be maintained for too long, and the battery cell 2 is still powered at this time; and when the second situation occurs, the battery cell 2 will continue to resist the contact switch 34, and it can be judged that the battery cell 2 is bulging at this time. In order to avoid subsequent safety accidents, the control chip 31 disconnects the battery cell 2 and the power switch 37 supplies power, and the control chip 31 enters a dormant state at the same time; when the plug module 12 is connected to the electronic device, the control chip 31 controls the display structure 33 to emit red light to remind the user, and does not charge the electronic device at the same time, which has the effect of warning the user to replace the battery cell 2.

[0072] In this embodiment, the first power connection structure 4 includes a first power connection member 41 and a second power connection member 42. The first power connection member 41 and the second power connection member 42 are both arranged inside the housing 1 and are integrally injection molded with the housing 1. The first power connection member 41 and the second power connection member 42 are both electrically connected to the control module 3. A slot is formed between the first power connection member 41 and the second power connection member 42. The ends of the first power connection member 41 and the second power connection member 42 facing each other are respectively provided with a spring portion 43.

[0073] The second power connection structure 5 has a conductive portion for inserting into the slot. The second power connection structure 5 and the sliding cover 6 are integrally injection molded. The conductive portion is exposed outside the sliding cover 6 and is inserted into the slot to contact the elastic sheet portion 43 .

[0074] That is, the first power connection member 41 and the second power connection member 42 are located in the housing 1 when the housing 1 is injection molded, and the two together with the control module 3, the battery cell 2, and the second power connection structure 5 form a loop; when the sliding cover 6 is slid, the second power connection structure 5 will withdraw from the slot, so that the above-mentioned loop cannot be formed and is in an open circuit state. At this time, the battery cell 2 is no longer powered, so the user will not be electrocuted when the battery cell 2 is replaced, thereby improving safety.

[0075] In this embodiment, a fixed module 15 for fixing the battery cell 2 is further provided in the housing 1. The fixed module 15 includes a fixed clamping member 151, a movable clamping member 152 and an elastic member 153. The fixed clamping member 151 is fixed in the housing 1, the movable clamping member 152 is provided in the housing 1, and the elastic member 153 is provided between an end of the movable clamping member 152 facing away from the fixed clamping member 151 and the housing 1. The fixed clamping member 151 cooperates with the movable clamping member 152 to position the battery cell 2.

[0076] The movable clamping member 152 is provided with a control member 154 , the sliding cover 6 is provided with a control groove 61 , the control member 154 is slidably provided in the control groove 61 , and the control member 154 is also provided with an anti-falling portion for preventing the control member 154 from escaping from the control groove 61 .

[0077] Since the bulging of the battery cell 2 will cause the volume of the battery cell 2 to increase, the present invention adopts a method of fixing the battery cell 2 at one end and moving the other end at the beginning of fixing the battery cell 2; and when the sliding cover 6 is opened, the movable clamping member 152 slides a certain distance relative to the control member 154 so that the control member 154 contacts one end of the control groove 61, and then the sliding cover 6 is controlled to slide, so that the sliding cover 6 can drive the movable clamping member 152 away from the fixed clamping member 151, and the cooperation between the control member 154 and the control groove 61 can also prevent the sliding cover 6 from separating from the outer shell 1.

[0078] The control groove 61 drives the control member 154 to retreat, and at the same time drives the movable clamping member 152 to retreat, so that there is more space between the movable clamping member 152 and the fixed clamping member 151 for convenient removal of the battery cell 2, so that the battery cell 2 can be taken out with as little external force as possible, avoiding the battery cell 2 from being punctured and leaking, thereby ensuring safety.

[0079] At the same time, when the battery cell 2 is bulging, its force is enough to open the movable clamping member 152, allowing the movable clamping member 152 to retreat and make way. At this time, a careful user can determine whether the battery cell 2 is bulging by observing the position of the control member 154, and thus replace it in time.

[0080] In this embodiment, the two sides of the containing groove 11 are respectively provided with a clamping module 16, the clamping module 16 includes a clamping member 161, a buffer member 162, a magnet 163 and an electromagnet 164, the clamping member 161 is provided with a sliding member 165, the containing groove 11 is provided with a slide rail 17, the sliding member 165 is slidably arranged on the slide rail 17, the buffer member 162 is arranged between the clamping member 161 and the inner side wall of the containing groove 11, the magnet 163 is arranged on the sliding member 165, and the electromagnet 164 is arranged in the containing groove 11 and is electrically connected to the control module 3;

[0081] The buffer member 162 is used to force the clamping member 161 to move toward the electromagnet 164 . When the plug module 12 is inserted into the electronic device, the control module 3 controls the electromagnet 164 to be energized to force the magnet 163 to move away from the electromagnet 164 .

[0082] That is, different mobile phones have different specifications. The present invention maintains the clamping member 161 in an open state through the buffer member 162 (preferably a spring 1224 structure) until the mobile phone is placed in the receiving slot 11 and successfully connected to the plug module 12. The electromagnet 164 is actuated to force the magnet 163 away, thereby driving the clamping member 161 to move and clamp the mobile phone; the mutual force between the electromagnet 164 and the magnet 163 is greater than the elastic force of the buffer member 162, but not too large, and preferably can just clamp the mobile phone without pinching the mobile phone, thereby ensuring that the mobile phone is reliably and stably located in the receiving slot 11 for charging.

[0083] Specifically, the control chip 31 is connected to a control button 36. When the control button 36 is pressed, the control chip 31 controls the electromagnet 164 to be powered off. That is, when charging is completed, the user can press the control button 36.
