[0026] The additional mounting shell 201 is detachably connected to the mounting shell 101 , and has a connected state in which the additional mounting shell 201 is connected to the mounting shell 101 , and a disassembled state in which the additional mounting shell 201 is disassembled from the mounting shell 101 .

[0027] The user can choose to keep the mobile power supply body 2 connected to the emergency power supply body 1, or remove the mobile power supply body 2 from the emergency power supply body 1 according to the use needs, so that the car emergency power supply has different usage forms. Especially when it is inconvenient to move the emergency power supply body 1, the mobile power supply body 2 that can charge electronic devices such as mobile phones and tablets can be removed and used separately through the detachable design, which is more convenient to use.

[0028] In some embodiments, the emergency power supply body 1 also includes a charging output circuit electrically connected to the first controller 103, so that the emergency power supply body 1 can also charge electronic devices such as mobile phones and tablets, and users can choose to charge according to their needs.

[0029] In this embodiment, the installation housing 101 is provided with a first sensor 1011 electrically connected to the first controller 103, and the additional installation housing 201 is provided with a first induction triggering member 2011 matched with the first sensor 1011; when the additional installation housing 201 is in a connected state, the first induction triggering member 2011 is correspondingly located in the induction triggering area of ​​the first sensor 1011, and the first controller 103 is configured to obtain a trigger signal of the first sensor 1011, and then output charging to the additional charging input circuit 205 through the additional charging output circuit 105, so as to charge the second storage battery assembly 202. Intelligently detect whether the mobile power supply body 2 is put back in place (whether the additional installation housing 201 is in the connection position of the connection state), automatically charge, and effectively ensure the power and availability of the mobile power supply body 2.

[0030] In some embodiments, the additional charging output circuit 105 may provide charging output to the additional charging input circuit 205 via wired charging output.

[0031] like Figure 2 As shown, the additional charging output circuit 105 has an additional charging output interface 1051 , and the additional charging output interface 1051 is a spring pin installed on the mounting housing 101 .

[0032] The additional charging input circuit 205 has an additional charging input interface 2051 , which is a contact point installed on the additional mounting housing 201 and matched with a spring ejector pin.

[0033] In some embodiments, the additional charging output circuit may provide charging output to the additional charging input circuit in a wireless charging output manner, for example, the additional charging output circuit has a wireless output coil, and the additional charging input circuit has a matching wireless input coil.

[0034] In this embodiment, after obtaining the trigger signal of the first sensor 1011, the first controller 103 first determines whether the power of the first battery assembly 102 is lower than the first power threshold; when the power of the first battery assembly 102 is not lower than the first power threshold, the additional charging output circuit 105 is used to charge and output to the additional charging input circuit 205; when the current of the first battery assembly 102 is lower than the first power threshold, the additional charging output circuit 105 is not used to charge and output to the additional charging input circuit 205. Intelligent charging output ensures that the emergency power supply body 1 can retain the power for emergency starting of the car as much as possible.

[0035] Preferably, the first power threshold is 60% power.

[0036] In this embodiment, the first induction trigger member 2011 includes a magnet installed on the additional installation housing 201 , and the first sensor 1011 includes a reed switch or a Hall sensor installed on the installation housing 101 .

[0037] In this embodiment, the installation housing 101 is provided with an installation slot 1012 for installing an additional installation housing, the installation slot 1012 has an installation slot opening 1013, a magnetic attraction component 1014 is installed in the installation slot 1012, and a magnetic attraction matching component 2012 matching with the magnetic attraction component 1014 is installed on the additional installation housing 201. When the additional installation housing 201 is in a connected state, the additional installation housing 201 is installed into the installation slot 1012 from the installation slot opening 1013 of the installation slot and is configured so that the magnetic attraction matching component 2012 is magnetically connected by the magnetic attraction component 1014.

[0038] In some embodiments, the magnetic attraction member 1014 may be installed on the inner wall of the installation slot opposite to the installation slot opening.

[0039] In some embodiments, the additional charging output interface 1051 may be a spring pin installed on the inner wall of the installation slot opposite to the installation slot.

[0040] When the additional installation shell 201 is installed into the installation groove 1012, the magnetic attraction component 1014 magnetically connects the magnetic attraction fitting 2012 so that the additional installation shell 201 can remain connected to the installation groove 1012. By setting the magnetic connection direction to be the same as the contact direction of the spring ejector pin, the magnetic attraction force can be used to make the contact between the spring ejector pin and the contact more stable.

[0041] The magnetic attraction member 1014 is a magnet, and the magnetic attraction matching member 2012 is an iron block. In some embodiments, the magnetic attraction matching member 2012 can also be a magnet.

[0042] In this embodiment, the mobile power source body 2 further includes a first lighting circuit 206 electrically connected to the second controller 203 .

[0043] When the additional installation housing 201 is in a connected state, the additional installation housing 201 is correspondingly formed with a lighting side surface 2013 opposite to the installation slot 1013 , and a first lighting window 2014 corresponding to the installation slot is formed on the lighting side surface 2013 .

[0044] The first lighting circuit 206 includes a first lamp group 2061 which is installed in the additional installation housing 201 and illuminates outward through the first lighting window 2014 .

[0045] Preferably, the additional installation shell 201 is arranged in a long strip shape, the lighting side 2013 is a side with a long side on the additional installation shell 201, the first lighting window 2014 extends along the length direction of the additional installation shell 201 on the lighting side 2013 to form a long window, and the first lamp group 2061 is extended along the length direction of the first lighting window 2014.

[0046] If the first lamp group 2061 is composed of a plurality of LED lamps, the plurality of LED lamps are spaced apart along the length direction of the first lighting window 2014; if the first lamp group is composed of a lamp tube, the length direction of the lamp tube is the same as the length direction of the first lighting window.

[0047] In some embodiments, the first light group 2061 can emit white light or red light.

[0048] In some embodiments, the first light group 2061 can be used as a red light indicator.

[0049] In this embodiment, the mobile power source body 2 further includes a second lighting circuit 207 electrically connected to the second controller 203 .

[0050] When the additional installation housing 201 is in a connected state, the additional installation housing 201 is correspondingly formed with an illumination end surface 2015 shielded and protected by one of the inner side walls of the installation groove 1012 , and a second illumination window 2016 is opened on the illumination end surface 2015 .

[0051] The second lighting circuit 207 includes a second lamp group 2071 which is installed in the additional installation housing 201 and illuminates outward through the second lighting window 2016 .

[0052] In some embodiments, the second lamp group 2071 can be used as a white light lamp. Preferably, a second sensor 2017 electrically connected to the second controller 203 is installed on the additional installation housing 201, and a second induction triggering member 1015 cooperating with the second sensor 2017 is installed on the installation housing 101. When the additional installation housing 201 is in a connected state, the second induction triggering member 1015 is correspondingly located in the induction triggering area of ​​the second sensor 2017, and the second controller 203 is configured to control the second lamp group 2071 in the second lighting circuit 207 to turn off after obtaining the trigger signal of the second sensor 2017.

[0053] The second inductive trigger 1015 includes a magnet installed on the mounting housing 101 , and the second sensor 2017 includes a reed switch or a Hall sensor installed on the additional mounting housing 201 .

[0054] The user can use different forms of lighting according to the needs, such as using the first light group 2061 to provide warning lighting that is easier to be discovered by other users and drivers of other vehicles, or using the second light group 2071 to provide lighting that makes it easier for users to hold.

[0055] When performing warning lighting, the user can place the mobile power supply body 2 at any position for warning lighting, or put the mobile power supply body 2 back on the emergency power supply body 1 midway. For example, when the power of the mobile power supply body 2 is low or when it is maintained with the help of the installation shell 101, safer uninterrupted warning lighting can be performed.

[0056] The strip-shaped setting of the additional mounting housing 201, on the one hand, can reserve a larger first lighting window 2014 for the first light group 2061 used for warning lighting, making the warning more obvious, and in combination with the structure of the emergency power supply body 1, can provide safer uninterrupted warning lighting, and on the other hand, can be more convenient to hold when lighting is performed by the second light group 2071. In the above case, when the user forgets to turn off the second light group 2071 after lighting and directly puts the mobile power supply body 2 back on the emergency power supply body 1, the above detection control can turn off the second light group 2071 in time, and the control is more intelligent.

[0057] In some embodiments, the first controller 103 has control buttons for controlling ignition output and charging output.

[0058] In some embodiments, the second controller 203 has a control button for controlling the lighting switch.

[0059] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
