[0025] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] like Figures 1 to 3 As shown, in one embodiment, the vehicle includes a vehicle body 10, a vehicle door 20, a door lock, a vehicle power supply, a door lock switch circuit 30, and a door lock control circuit 40. The vehicle may be an electric vehicle, a hybrid vehicle, a fuel vehicle, and the like.

[0027] The vehicle door 20 is installed on the vehicle body 10, and the door lock is used to lock and unlock the vehicle door 20; when the vehicle body 10 and the vehicle door 20 are locked, the vehicle door 20 cannot be opened; when the vehicle door 20 is unlocked, the vehicle door 20 can move relative to the vehicle body 10 to open or close the vehicle door 20.

[0028] The vehicle power supply can supply power to the door lock switch circuit 30, and the door lock switch circuit 30 is used to control the locking or unlocking of the door lock. When the door lock is locked, the door 20 can be locked; when the door lock is unlocked, the door 20 can be unlocked. The vehicle power supply is a battery that the vehicle itself has for powering the corresponding electrical components of the vehicle. For example, when the vehicle is a hybrid vehicle or an electric vehicle, the vehicle power supply includes the vehicle's power battery and a corresponding backup battery. The door lock switch circuit 30 can be one of the existing technologies, and this embodiment is not limited in detail.

[0029] The door lock control circuit 40 is an emergency circuit. When the power supply of the vehicle is exhausted, the power supply of the vehicle cannot supply power to the door lock switch circuit 30. At this time, the door lock control circuit 40 can use the backup power supply 50 to supply power to the door lock switch circuit 30 so as to lock or unlock the door lock. The backup power supply 50 can be a mobile power supply such as a power bank, or the backup power supply can also be a power supply such as a mains electricity. It should be understood that the power output end of the door lock control circuit 40 is electrically connected to the door lock circuit 30, and the power input end of the door lock control circuit 40 is used to electrically connect the backup power supply 50, so that the backup power supply 50 can supply power to the door lock switch circuit 30 through the door lock control circuit 40.

[0030] In addition, the control of the door lock is mainly achieved by controlling the forward and reverse rotation of the door lock motor to achieve locking or unlocking of the door lock, wherein the door lock motor can be regarded as a part of the door lock switch circuit 30. For example, when the motor is controlled to rotate forward, the door lock can be locked, and when the motor is controlled to rotate reversely, the door lock can be unlocked. When the power supply of the whole vehicle is exhausted and the door 20 needs to be opened, the motor can be powered forward by the backup power supply 50 to make the motor rotate forward; when the power supply of the whole vehicle is exhausted and the door 20 needs to be locked, the motor can be powered reversely by the backup power supply 50 to make the motor rotate reversely.

[0031] In addition, the door lock switch circuit 30 includes a power connection end, and the power connection end of the door lock switch circuit 30 can be electrically connected to the power supply of the whole vehicle, so that the door lock switch circuit 30 is powered by the power supply of the whole vehicle. Among them, the power output end of the door lock control circuit 40 can be electrically connected to the power connection end of the door lock switch circuit 30, so that the backup power supply 50 can power the entire door lock switch circuit 30. Of course, when the backup power supply 50 supplies power to the door lock switch circuit 30, it can only supply power to a part of the circuit of the door lock switch circuit 30. For example, the power output end of the door lock control circuit 40 can be directly electrically connected to the power connection end of the motor of the door lock, and at this time, the backup power supply 50 can only supply power to the motor of the door lock.

[0032] like Figure 3 As shown, in one embodiment, the door lock control circuit 40 includes a switching element 1, wherein the switching element 1 includes a control module 11 (the portion within the dotted box in the figure can be regarded as the control module 11), a first terminal 12 and a second terminal 13; the control module 11 is used to connect to the vehicle power supply to power the control module 11 through the vehicle power supply; when the vehicle power supply powers the control module 11, the first terminal 12 and the second terminal 13 are electrically disconnected; when the vehicle power supply is disconnected from powering the control module 11, the first terminal 12 and the second terminal 13 are electrically connected; the first terminal 12 is used to be electrically connected to the backup power supply 50; the second terminal 13 is used to be electrically connected to the door lock switch circuit 30, and when the first terminal 12 and the second terminal 13 are electrically connected, the path between the backup power supply 50 and the door lock switch circuit 30 can be turned on. That is, when the backup power supply 50 is electrically connected to the first terminal 12, if the first terminal 12 and the second terminal 13 are electrically connected, the backup power supply 50 is electrically conductive with the door lock switch circuit 30 electrically connected to the second terminal 13. At this time, the backup power supply 50 can supply power to the door lock switch circuit 30 so as to lock or unlock the door lock.

[0033] When the vehicle power supply is disconnected from supplying power to the control module 11 (for example, when the vehicle is parked for a long time and the vehicle power supply is exhausted), the first terminal 12 and the second terminal 13 are electrically connected. At this time, the first terminal 12 can be electrically connected to the backup power supply 50 outside the vehicle, and the backup power supply 50 can supply power to the door lock through the first terminal 12 to unlock the door 20. In this way, the door 20 can be pushed from the outside of the vehicle to open it.

[0034] That is, through the configuration of this embodiment, when the battery is exhausted and the vehicle is powered off, the backup power supply 50 can be used to power the door lock to facilitate opening the vehicle door 20. It should be understood that the power output end of the door lock control circuit 40 is the second terminal 13, and the power input end of the door lock control circuit 40 is the first terminal 12.

[0035] When the vehicle power supply has power, it can continuously supply power to the control module 11, so that the first terminal 12 and the second terminal 13 can remain disconnected. At this time, even if the first terminal 12 is electrically connected to the backup power supply 50, the backup power supply 50 will not supply power to the door lock.

[0036] In addition, when the vehicle power supply has power, when the door lock needs to be controlled to unlock the door 20, the door lock switch circuit 30 can be powered by the vehicle power supply. Among them, the setting of controlling the vehicle power supply to power the door lock switch circuit 30 can be a prior art.

[0037] like Figure 3 As shown, in one embodiment, the first terminal 12 includes a first connection terminal 121 and a second connection terminal 122, and the first connection terminal 121 and the second connection terminal 122 are respectively used to connect the two power output terminals of the backup power supply 50; the second terminal 13 includes a third connection terminal 131 and a fourth connection terminal 132, and the third connection terminal 131 and the fourth connection terminal 132 are respectively used to connect the two power input terminals of the door lock switch circuit 30; when the vehicle power supply is disconnected from supplying power to the control module 11, the first connection terminal 121 and the third connection terminal 131 are electrically connected, and the second connection terminal 122 and the fourth connection terminal 132 are electrically connected; when the vehicle power supply supplies power to the control module 11, the first connection terminal 121 and the third connection terminal 131 are electrically disconnected, and / or the second connection terminal 122 and the fourth connection terminal 132 are electrically disconnected.

[0038] The electrical connection between the first terminal 12 and the second terminal 13 means that the first connection end 121 is electrically connected to the third connection end 131 , and the second connection end 122 is electrically connected to the fourth connection end 132 .

[0039] The first terminal 12 and the second terminal 13 are electrically disconnected, which means that the first connection end 121 and the third connection end 131 are electrically disconnected, and / or the second connection end 122 and the fourth connection end 132 are electrically disconnected.

[0040] In addition, it should be understood that the power connection end of the door lock switch circuit 30 includes two terminals, which are respectively electrically connected to the two power output terminals of the vehicle power supply. When the backup power supply 50 supplies power to the entire door lock switch circuit 30 through the door lock control circuit 40, the two terminals of the power connection end of the door lock switch circuit 30 can be the two power input terminals of the above-mentioned door lock switch circuit 30, that is, the two terminals of the power connection end of the door lock switch circuit 30 can be respectively electrically connected to the third connection terminal 131 and the fourth connection terminal 132.

[0041] Similarly, the power connection end of the door lock motor also includes two terminals. When the backup power supply 50 directly powers the door lock motor through the door lock control circuit 40, these two terminals of the door lock motor can be the two power input terminals of the above-mentioned door lock switch circuit 30, that is, these two terminals of the door lock motor can be electrically connected to the third connection terminal 131 and the fourth connection terminal 132, respectively.

[0042] like Figure 3 As shown, in one embodiment, the switching element 1 includes a normally closed relay, a second connection terminal 122 and a fourth connection terminal 132; the normally closed relay includes a coil and a controlled contact, the controlled contact includes a first connection terminal 121 and a third connection terminal 131, and the control module 11 includes a coil; when the coil is powered, the first connection terminal 121 and the third connection terminal 131 are electrically disconnected; when the coil is powered off, the first connection terminal 121 and the third connection terminal 131 are electrically connected; the second connection terminal 122 and the fourth connection terminal 132 are electrically connected; the first terminal 12 includes a first connection terminal 121 and a second connection terminal 122, and the second terminal 13 includes a third connection terminal 131 and a fourth connection terminal 132.

[0043] Among them, the vehicle power supply to the control module 11 can be regarded as powering the coil. The controlled contacts are a group of normally closed contacts of a normally closed relay, which include a first connection terminal 121 and a third connection terminal 131. When the coil of the normally closed relay is powered, the normally closed contact is disconnected (that is, the first connection terminal 121 and the third connection terminal 131 are electrically disconnected), and when the coil of the normally closed relay is not powered, the normally closed contact is connected (that is, the first connection terminal 121 and the third connection terminal 131 are electrically connected). In addition, the normally closed relay can be an existing design, and this embodiment will not be described in detail here.

[0044] In addition, the second connection terminal 122 can be a wiring terminal, or it can be one end of a conductive wire or a region where the conductive wire is used for electrical contact and connection with other objects. Similarly, the fourth connection terminal 132 can be a wiring terminal, or it can be one end of a conductive wire or a region where the conductive wire is used for electrical contact and connection with other objects. When the second connection terminal 122 and the fourth connection terminal 132 are both wiring terminals, they can also be electrically connected through corresponding conductive wires. Moreover, in this embodiment, regardless of whether the vehicle power supply supplies power to the control module 11, the second connection terminal 122 and the fourth connection terminal 132 remain electrically connected.

[0045] like Figure 3 As shown, in one embodiment, the switching element 1 further includes a fifth connection terminal 14, the fifth connection terminal 14 is electrically connected to the first connection terminal 121, and the fifth connection terminal 14 and the second connection terminal 122 are integrated in the first external port 2 (refer to Figure 2 ). The fifth connection terminal 14 is used to lead out the first connection terminal 121 of the normally closed relay. The fifth connection terminal 14 and the second connection terminal 122 are integrated into one external connection port, which can facilitate the electrical connection between the first terminal 12 and the backup power supply 50, and can also make the conductive wires of the entire circuit neater. In addition, the fifth connection terminal 14 and the first connection terminal 121 can be electrically connected through a conductive wire.

[0046] In one embodiment, the first external port 2 includes at least one of a Micro USB interface, a USB Type C interface, and a Lightning interface.

[0047] In one embodiment, the switching element 1 further includes a sixth connection terminal 15, which is electrically connected to the third connection terminal 131, and the sixth connection terminal 15 and the third connection terminal 131 are integrated in the second external port. This facilitates the electrical connection between the second terminal 13 and the door lock switch circuit 30.

[0048] like Figure 3 As shown, in one embodiment, the door lock control circuit 40 further includes a seventh connection terminal 3 and an eighth connection terminal 4, which are electrically connected to the control module 11 respectively; the control module 11 is electrically connected to the vehicle power supply through the seventh connection terminal 3 and the eighth connection terminal 4; at least one of the seventh connection terminal 3 and the eighth connection terminal 4 is a pluggable terminal so as to be pluggable and connected to the vehicle power supply. This makes it more convenient for the door lock control circuit 40 to be electrically connected to the vehicle power supply.

[0049] Among them, the pluggable terminal can be a male terminal, and the vehicle power supply is connected with a female terminal adapted to the male terminal so that the two can be plugged in and out. Of course, the pluggable terminal can also be a female terminal, and the vehicle power supply is connected with a male terminal adapted to the female terminal.

[0050] In addition, the seventh connection terminal 3 and the eighth connection terminal 4 may be electrically connected to the control module 11 via conductive wires.

[0051] In one embodiment, the first external port 2 may be installed on the vehicle door 20 or on the vehicle body 10, and when the vehicle door 20 is closed, a backup power source 50 such as a mobile power source may be electrically connected to the first external port 2 outside the vehicle. When the first external port 2 is connected to the vehicle door 20, the first external port 2 may be installed on the outer surface of the sheet metal of the vehicle door 20. When the first external port 2 is connected to the vehicle body 10, the first external port 2 may be installed on the outer surface of the vehicle body 10.

[0052] In addition, if Figure 2 As shown, the vehicle also includes an outer decorative panel 60, which is installed on the vehicle body 10 and the door 20, wherein a window 601 is provided on the outer decorative panel 60, and the first terminal 12 is used to electrically connect the backup power supply 50 from the window 601, so that the first terminal 12 and the like can be shielded by the outer decorative panel 60.

[0053] In addition, the first terminal 12 is electrically connected to the backup power supply 50 from the window 601, which may mean that the first external port 2 is electrically connected to the backup power supply 50 from the window 601. In addition, the first external port 2 may be exposed from the window 601, so as to realize the electrical connection between the first external port 2 and the backup power supply 50 from the window 601. Moreover, the first external port 2 does not protrude from the outer surface of the outer decorative plate 60 from the window 601, so that the first external port 2 can be shielded by the outer decorative plate 60.

[0054] The first external connection port 2 may be installed between the outer decorative panel 60 and the vehicle body 10 , or the first external connection port 2 may be installed between the outer decorative panel 60 and the vehicle door 20 .

[0055] “The first external port 2 can be exposed from the window 601” mainly refers to that the second connection terminal 122 and the fifth connection terminal 14 are exposed from the window 601. Specifically, it can be: in an orthographic projection on a plane perpendicular to the axis of the window 601, the projections of the second connection terminal 122 and the fifth connection terminal 14 both coincide with the projection of the window 601, wherein the axis of the window 601 can be parallel to the width direction of the vehicle.

[0056] In one embodiment, the vehicle further comprises a plug cover, which is connected to the outer decorative panel 60 and is used to open or close the window 601. When the plug cover closes the window 601, the first external port 2 cannot be seen from the outside of the vehicle; when the plug cover opens the window 601, the first external port 2 is exposed from the window 601.

[0057] The design of the plug cover to open or close the window 601 can be based on existing technology, such as a design similar to the fuel tank cover to close the refueling window 601.

[0058] like Figure 2 As shown, in one embodiment, the first external connection port 2 is installed on the outer surface of the B-pillar 101 of the vehicle body 10. At this time, the first external connection port 2 is located between the B-pillar 101 and the B-pillar outer decorative plate, and the window 601 is located on the B-pillar first external connection port 2. The B-pillar outer decorative plate is a part of the structure of the automobile outer decorative plate 60.

[0059] In one embodiment, the door lock and the switching element 1 are installed on the vehicle door 20. The door lock and the switching element 1 can both be installed on the inner side of the vehicle door 20. Specifically, both can be installed between the sheet metal of the vehicle door 20 and the interior panel of the vehicle door 20. Of course, in other embodiments, either the door lock or the switching element 1 can also be installed on the vehicle body 10.

[0060] In one embodiment, the entire vehicle power supply is installed on the vehicle body 10. Of course, in other embodiments, a part of the vehicle power supply may also be installed on the vehicle door 20.

[0061] It should be understood that the above-mentioned related designs can also be replaced by other methods, such as:

[0062] Of course, in other embodiments, the second connection terminal 122 and the fourth connection terminal 132 may also be another set of normally closed contacts of a normally closed relay. In this embodiment, when the vehicle power supply supplies power to the control module 11, the second connection terminal 122 and the fourth connection terminal 132 are electrically disconnected; when the vehicle power supply does not supply power to the control module 11 (i.e., when the coil is not energized), the second connection terminal 122 and the fourth connection terminal 132 are electrically connected.

[0063] In other embodiments, in the door lock control circuit 40, any one of the fifth connection terminal 14, the sixth connection terminal 15, the seventh connection terminal 3 and the eighth connection terminal 4 may not be provided.

[0064] In other embodiments, the switching element 1 may not include a complete normally closed relay. In this case, the switching element 1 may include components of the normally closed relay except the housing.

[0065] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
