[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0048] Some embodiments of the present application provide an electrical connector, such as Figures 1 to 3 As shown, the electrical connector 100 includes a first connecting portion 10 for connecting to a power source and a second connecting portion 20 for connecting to a load. The second connecting portion 20 is plug-fitted with the first connecting portion 10 along a first direction X.

[0049] When the first connection part 10 is connected to the power source and the second connection part 20 is connected to the load, the second connection part 20 is plugged into the first connection part 10 to achieve connection between the power source and the load, thereby achieving power supply.

[0050] Please continue reading Figures 1 to 3The electrical connector 100 further includes a connecting mechanism 30 , which is connected to the first connecting portion 10 and the second connecting portion 20 to limit relative movement of the first connecting portion 10 and the second connecting portion 20 along the first direction X. In other words, due to the presence of the connecting mechanism 30 , the first connecting portion 10 and the second connecting portion 20 will not undergo relative displacement in the first direction X, thereby ensuring the plug-in stability between the first connecting portion 10 and the second connecting portion 20, thereby improving the connection stability between the power supply and the load.

[0051] like Figures 2 to 5 As shown, the electrical connector 100 also includes a driving mechanism 40, which is used to drive the connecting mechanism 30 to move, so as to disconnect the connecting mechanism 30 from at least one of the first connecting part 10 and the second connecting part 20, and to release the movement restriction of the first connecting part 10 and the second connecting part 20 in the first direction X.

[0052] The drive mechanism 40 can drive the connecting mechanism 30 to move in at least one of translational motion and rotational motion. For example, the connecting mechanism 30 can move in translational motion, rotational motion, or a combination of translational motion and rotational motion under the drive mechanism 40. After the connecting mechanism 30 moves, the relative position between the connecting mechanism 30 and the first connecting portion 10 and the second connecting portion 20 changes, thereby releasing the relative movement restriction between the first connecting portion 10 and the second connecting portion 20 in the first direction X.

[0053] Therefore, the electrical connector 100 provided in the embodiment of the present application can drive the connecting mechanism 30 to move via the driving mechanism 40, thereby changing the relative positional relationship between the connecting mechanism 30 and the first connecting portion 10 and the second connecting portion 20, thereby releasing the relative movement restriction between the first connecting portion 10 and the second connecting portion 20 in the first direction X. In this way, the connection between the power supply and the load can be disconnected, thereby facilitating disconnection when an abnormality occurs in the power supply.

[0054] In some embodiments, as Figures 1 to 3 As shown, the connecting mechanism 30 includes a rotating element 31 and a rotating shaft element 32. The rotating element 31 defines a rotating shaft hole 310, into which the plug end 3201 of the rotating shaft element 32 is inserted. Once the plug end 3201 is inserted into the rotating shaft hole 310, the rotating element 31 can rotate about the plug end 3201. A first limiting element 11 is provided on the first connecting portion 10, and a second limiting element 21 is provided on the second connecting portion 20. Both the first limiting element 11 and the second limiting element 21 abut against the rotating element 31 to restrict rotation of the rotating element 31 about the plug end 3201.

[0055] In this case, since the plug-in end 3201 of the shaft element 32 is inserted into the shaft hole 310, and the first limiting element 11 and the second limiting element 21 are both in contact with the rotating element 31 to limit the rotation of the rotating element 31 around the plug-in end 3201, the positional relationship between the rotating element 31, the first connecting part 10 and the second connecting part 20 can be kept relatively fixed, thereby effectively locking the plug-in between the first connecting part 10 and the second connecting part 20.

[0056] The drive mechanism 40 is used to drive the shaft element 32 to move, thereby allowing the plug end 3201 to disengage from the shaft hole 310. As an example, the drive mechanism 40 can drive the shaft element 32 to move in translation, thereby causing the plug end 3201 to translate and disengage from the shaft hole 310. As another example, the drive mechanism 40 can drive the plug end 3201 to rotate while simultaneously moving in translation, thereby disengaging from the shaft hole 310.

[0057] In some examples, the portion of the plug end 3201 inserted into the shaft hole 310 also abuts against one of the first connection portion 10 and the second connection portion 20 , which can improve the stability of the overall structure.

[0058] In some embodiments, as Figures 3 to 6 As shown, the shaft element 32 includes a first shaft segment 321, a second shaft segment 322, and a third shaft segment 323, which are connected in sequence. The first shaft segment 321 and the third shaft segment 323 are arranged in parallel and are located on the same side of the second shaft segment 322. The plug end 3201 is located at the free end of the first shaft segment 321, that is, the plug end 3201 is located at the end of the first shaft segment 321 away from the second shaft segment 322. As an example, the first shaft segment 321, the second shaft segment 322, and the third shaft segment 323 can be connected end to end, and any two shaft segments can be connected by a transition segment to achieve a change in the extension direction of each shaft segment.

[0059] Based on this, the driving mechanism 40 is used to drive the third rotating shaft segment 323 to move in a translational direction along the length direction of the third rotating shaft segment 323 , so as to drive the plug end 3201 to separate from the rotating shaft hole 310 .

[0060] With this arrangement, the free end of the first shaft segment 321 can be moved by driving the third shaft segment 323, thereby enabling the plug end 3201 to disengage from the shaft hole 310. Because the first shaft segment 321 and the third shaft segment 323 are arranged in parallel, when the plug end 3201 needs to be moved horizontally and disengaged from the shaft hole 310, this can be achieved by driving the third shaft segment 323 horizontally in the same direction. This helps ensure the stability of the process during which the plug end 3201 disengages from the shaft hole 310. Furthermore, because the first shaft segment 321 and the third shaft segment 323 are both located on the same side of the second shaft segment 322, this helps conserve space occupied by the shaft element 32, thereby further simplifying the structure of the electrical connector 100.

[0061] In some examples, the extension direction of the second shaft segment 322 can be linear, broken line, or curved, or a combination of any number of linear, broken line, and curved shapes, which is not limited in the embodiments of the present application.

[0062] In some embodiments, as Figures 3 to 7 As shown, one of the first connection portion 10 and the second connection portion 20 is the selected connection portion. For ease of explanation, the second connection portion 20 is used as an example for illustration below, but this example does not limit the selection of the selected connection portion.

[0063] The second connecting portion 20 is provided with a retaining groove 201. The rotating shaft element 32 has another end, namely a movable end 3202, located away from the plug-in end 3201. The movable end 3202 is located within the retaining groove 201, which serves to restrict the rotating shaft element 32 from rotating about the rotating shaft hole 310. In other words, after the plug-in end 3201 of the rotating shaft element 32 is inserted into the rotating shaft hole 310 and the movable end 3202 of the rotating shaft element 32 is disposed within the retaining groove 201, the rotating shaft element 32 is restricted by the rotating shaft hole 310 and the retaining groove 201, and can only move horizontally along the depth direction of the rotating shaft hole 310.

[0064] When the shaft element 32 includes the first shaft segment 321 , the second shaft segment 322 and the third shaft segment 323 , the movable end 3202 is located at the free end of the third shaft segment 323 , that is, the movable end 3202 is located at the end of the third shaft segment 323 away from the second shaft segment 322 .

[0065] The movable end 3202 is provided with a rack 32021 along its length. A drive mechanism 40 is disposed on a selected connection portion (e.g., the second connection portion 20). A gear 401 is provided at the output end of the drive mechanism 40. The gear 401 is positioned within the retaining groove 201 and meshes with the rack 32021. This allows the drive mechanism 40 to utilize the meshing between the gear 401 and the rack 32021 to drive the movable end 3202 along its length, thereby disengaging the plug-in end 3201 of the rotating shaft element 32 from the rotating shaft hole 310. Since the rotating element 31 is no longer constrained by the rotating shaft element 32, the connection between the rotating element 31 and the first and second connection portions 10, 20 is broken, thereby releasing the restriction on relative movement of the first and second connection portions 10, 20 in the first direction X. This allows the power supply and load to be disconnected, facilitating disconnection in the event of a power failure.

[0066] In some examples, the driving mechanism 40 may be a rotary motor, etc., which can convert rotation into linear motion through the engagement between the gear 401 and the rack 32021 , thereby enabling the plug end 3201 to disengage from the shaft hole 310 .

[0067] In other examples, the drive mechanism 40 can be a linear drive mechanism such as a linear motor, an electric push rod, or a hydraulic push rod, which can be directly connected to the movable end 3202 of the rotating shaft element 32, thereby directly driving the plug end 3201 of the rotating shaft element 32 to disengage from the rotating shaft hole 310. The embodiments of the present application do not limit the specific implementation of the drive mechanism.

[0068] In some examples, such as Figures 2 to 4 As shown, a mounting bracket 22 is provided on a selected connection portion (e.g., the second connection portion 20), and the aforementioned limiting groove 201 is defined by the mounting bracket 22. In one embodiment, the mounting bracket 22 is further provided with a cover 23. After the movable end 3202 is placed in the limiting groove 201, the cover 23 can be fixed to the mounting bracket 22 to limit the movable end 3202 and allow the movable end 3202 to move along its length.

[0069] In some examples, a sliding frame 24 may be further provided on a selected connection portion (eg, the second connection portion 20 ), and the rotation shaft element 32 is mounted on the sliding frame 24 , thereby facilitating the sliding of the rotation shaft element 32 and ensuring the translational stability of the rotation shaft element 32 .

[0070] In some examples, an abutment 25 may also be provided on a selected connection portion (e.g., the second connection portion 20 ), and the position of the abutment 25 corresponds to the position of the shaft hole 310 . The abutment 25 is used to abut against the plug end 3201 after the plug end 3201 is inserted into the shaft hole 310 , thereby ensuring its structural stability.

[0071] In some embodiments, as Figure 1 、 Figure 2 、 Figure 8 as well as Figure 9 As shown, a slot 210 is defined between the second limiting element 21 and the second connecting portion 20. The rotating element 31 is partially located within the slot 210. The slot 210 is used to restrict the rotating element 31 from rotating about the plug end 3201. In other words, after the rotating element 31 is partially inserted into the slot 210, the sidewalls of the slot 210 restrict the rotating element 31 from rotating about the plug end 3201.

[0072] Therefore, through the restriction of the slot 210 , the structure of the second limiting element 21 can be made relatively simple, thereby saving the space occupied by the second limiting element 21 .

[0073] like Figure 2 As shown, the second limiting element 21 may be T-shaped, and the side arms extending from the second limiting element 21 and the second connecting portion 20 jointly define the slot 210 .

[0074] In some embodiments, please refer to Figure 1 、 Figure 2 、 Figure 8 as well as Figure 9 The rotating element 31 includes a rotating element body and a sliding member 33. The sliding member 33 is slidably connected to the rotating element body. One end of the sliding member 33 is inserted into the slot 210 and abuts against the second limiting member 21. The sliding connection between the sliding member 33 and the rotating element body means that the sliding member 33 and the rotating element body can be respectively provided with matching slide rails and sliders, and the sliders are embedded in the slide rails to achieve a sliding connection between the two.

[0075] Therefore, the provision of the sliding member 33 facilitates greater flexibility in the installation between the rotating element 31 and the second limiting element 21. For example, after the plug-in end 3201 of the rotating shaft element 32 is inserted into the rotating shaft hole 310, the sliding member 33 can be inserted into the retaining groove 210, thereby securing the rotating element 31 and the second limiting element 21. Furthermore, the provision of the sliding member 33 allows the rotating element 31 and the second limiting element 21 to be loosened after the sliding member 33 is slid out of the retaining groove 210, thereby facilitating the removal of the rotating element 31.

[0076] In some examples, such as Figure 9 As shown, the sliding member 33 may also be provided with an anti-slip protrusion 331 to facilitate manual installation of the sliding member 33 .

[0077] In some examples, after one end of the sliding member 33 is inserted into the slot 210 , the sliding member 33 also abuts against the second connecting portion 20 . This can lock the rotating element body, thereby preventing it from rotating around the plug end 3201 .

[0078] It can be understood that all parts of the rotating element 31 except the sliding member 33 can serve as the rotating element body.

[0079] In some embodiments, as Figure 1 、 Figure 2 as well as Figure 8 As shown, the rotating element 31 is provided with a slide groove 311, the extension direction of which is consistent with the direction in which the rotating element 31 rotates about the plug end 3201. The first limiting element 11 is partially embedded in the slide groove 311 and can slide along the extension direction of the slide groove 311. In other words, after the first limiting element 11 is partially embedded in the slide groove 311, the slide groove 311 and the first limiting element 11 will not interfere with each other during the rotation of the rotating element 31 about the plug end 3201. The position of the slide groove 311 changes as the rotating element 31 rotates, but the first limiting element 11 does not hinder the position change of the slide groove 311. The slide groove 311 is arc-shaped to adapt to the rotation of the rotating element 31.

[0080] After the plug-in end 3201 is inserted into the shaft hole 310, a relative movement relationship restriction is formed between the rotating element 31 and the first limiting element 11. That is to say, the first limiting element 11 and the first connecting part 10 to which it is connected are difficult to move along the length direction of the first connecting part 10, thereby realizing the relative movement restriction between the first connecting part 10 and the second connecting part 20 in the first direction X.

[0081] In some examples, one end of the first limiting element 11 is fixed to the first connecting portion 10 , and the other end thereof is embedded in the sliding groove 311 .

[0082] In some embodiments, please refer to Figure 1 、 Figure 2 as well as Figure 8 The sliding groove 311 has a closed end, and when the second limiting element 21 abuts against the rotating element 31 , the first limiting element 11 abuts against the closed end.

[0083] In this case, the cooperation between the closed end of the sliding groove 311 and the first limiting element 11 can prevent the rotating element 31 from rotating further, thereby achieving a good locking effect on the rotating element 31 .

[0084] When the rotating element 31 rotates in one direction, the second limiting element 21 can limit it, and when the rotating element 31 rotates in the other direction, the first limiting element 11 can limit it, thereby preventing the rotating element 31 from rotating around the plug end 3201.

[0085] In some embodiments, please refer to Figure 1 、 Figure 2 as well as Figure 8 The chute 311 has an opening 3111 at one end thereof away from the closed end.

[0086] In this arrangement, after the plug-in end 3201 disengages from the pivot hole 310, the rotating element 31 will no longer rotate around the pivot hole 310. At this time, if the first connecting part 10 is subjected to a force along its length direction, the first connecting part 10 will pull the rotating element 31 through the first limiting element 11, and in this process, the first limiting element 11 will disengage from the opening 3111 of the slide groove 311, thereby releasing the connection between the connecting mechanism 30 and the first connecting part 10, and further releasing the relative movement restriction between the first connecting part 10 and the second connecting part 20 in the first direction X.

[0087] In some embodiments, as Figure 1 and Figure 2 As shown, two groups of connection mechanisms 30 are provided, and the two groups of connection mechanisms 30 are respectively located on both sides of the first connection portion 10 .

[0088] With this arrangement, the connection stability between the first connection portion 10 and the second connection portion 20 can be further improved through the two sets of connection mechanisms 30, thereby ensuring a stable connection between the power supply and the load.

[0089] In some examples, the driving mechanism 40 can simultaneously drive the two groups of connection mechanisms 30 to move, so as to release the relative movement restriction in the first direction X between the first connection portion 10 and the second connection portion 20 .

[0090] In some examples, the rotating elements 31 in the two sets of connecting mechanisms 30 can be integrated, which helps improve the stability of the overall structure. For example, the rotating elements in the two sets of connecting mechanisms 30 can be connected as a whole and form a symmetrical structure. In this case, the sliding members 33 in the two sets of connecting mechanisms 30 can also be connected as a whole and form a symmetrical structure.

[0091] Some embodiments of the present application also provide a vehicle, such as Figure 1 、 Figure 10 as well as Figure 11 As shown, the vehicle 1000 includes a vehicle body 200 , a battery pack 300 and the electrical connector 100 described in any of the above embodiments. The battery pack 300 is connected to the first connection portion 10 , and the vehicle body 200 is connected to the second connection portion 20 .

[0092] In this case, the vehicle body 200 and the battery pack 300 are connected via the electrical connector 100, so that the battery pack 300 can supply power to the vehicle body 200. The vehicle body 200 includes all electrical devices in the vehicle.

[0093] In some examples, the battery pack 300 may be secured to the bottom of the vehicle body 200 .

[0094] Since the vehicle 100 includes the electrical connector 100 , the vehicle 1000 has the technical effects possessed by the aforementioned electrical connector 100 , which will not be described in detail here.

[0095] Furthermore, in the aforementioned vehicle, since the connection between the vehicle body 200 and the battery pack 300 is achieved via the electrical connector 100, when the battery pack 300 is installed on the vehicle body 200, the connection mechanism 30 can ensure a stable connection between the first connection portion 10 and the second connection portion 20, thereby ensuring stable power supply from the battery pack 300 to the vehicle body 200. In the event of thermal runaway of the battery pack 300, the drive mechanism 40 can drive the connection mechanism 30 to disconnect the connection mechanism 30 from at least one of the first connection portion 10 and the second connection portion 20, thereby removing the restriction on relative movement of the first connection portion 10 and the second connection portion 20 in the first direction X. In this case, after being released from the vehicle body 200, the battery pack 300 can be disconnected from the vehicle body 200, thereby ensuring safe detachment of the battery pack 300 from the vehicle body 200, thereby protecting the safety of the driver and passengers in the vehicle and preventing property damage caused by a burn of the vehicle body 200.

[0096] In some embodiments, as Figure 12 As shown, the battery pack 300 includes a battery management interface 301, a charging interface 302, and a discharging interface 303. At least one of the battery management interface 301, the charging interface 302, and the discharging interface 303 is connected to the vehicle body 200 via an electrical connector 100. For example, three sets of electrical connectors 100 are provided, and each of the battery management interface 301, the charging interface 302, and the discharging interface 303 is connected to the vehicle body 200 via a set of electrical connectors 100.

[0097] Therefore, the electrical connector 100 has good adaptability, is conducive to cost reduction, and forms platform management.

[0098] Some embodiments of the present application also provide a vehicle control system, such as Figure 13 As shown, the vehicle control system 2000 includes the electrical connector 100 described in any of the above embodiments, the first connecting portion 10 is used to connect to the battery pack 300, and the second connecting portion 20 is used to connect to the vehicle body 200.

[0099] The vehicle control system 2000 also includes a first detection unit 400 and a control unit 500, and the control unit 500 is electrically connected to the first detection unit 400 and the drive mechanism 40; wherein, the first detection unit 400 is used to detect whether the battery pack 300 has thermal runaway, and the control unit 500 is used to drive the drive mechanism 40 to work when the battery pack 300 has thermal runaway, so as to release the relative movement restriction of the first connecting part 10 and the second connecting part 20 in the first direction X.

[0100] In this case, when the first detection unit 400 detects thermal runaway of the battery pack 300, the control unit 500 controls the drive mechanism 40 to operate and releases the restriction on the relative movement of the first connecting portion 10 and the second connecting portion 20 in the first direction X. This facilitates the separation of the battery pack 300 from the first connecting portion 10 to which it is connected.

[0101] For example, the first detection unit 400 may be a temperature sensor that can detect the temperature of the battery cells in the battery pack. When it senses that the temperature exceeds a certain threshold, it can be determined that thermal runaway occurs in the battery pack 300 .

[0102] In some examples, the control unit 500 is further configured to issue an alarm when thermal runaway occurs in the battery pack 300, thereby alerting vehicle occupants. For example, the alarm may include an electronic alarm, i.e., an audible alarm. For example, the alarm content may include "Battery pack thermal runaway, enable battery pack disassembly." In another example, the alarm may include a hazard warning light to alert surrounding vehicles or people to the vehicle's abnormality.

[0103] In some embodiments, as Figure 14 As shown, the vehicle control system 2000 also includes a blasting unit 600, which is located in the connecting component 2001 that fixes the battery pack 300 to the vehicle body 200, and the blasting unit 600 is electrically connected to the control unit 500; the control unit 500 is also used to control the blasting unit 600 to explode when thermal runaway occurs in the battery pack 300, so as to destroy the connecting component 2001 and disconnect the connection between the battery pack 300 and the vehicle body 200.

[0104] like Figure 15 As shown, the blasting unit 600 may include explosives and fuses, and a storage space 2002 is provided on the connecting component 2001 to store the explosives, so that the connecting component 2001 can be blown up by detonating the explosives.

[0105] In some examples, the connection component 2001 has a weak area 2003 at the storage space 2002 , that is, the thickness at this location is thinner, so that it is easy to disconnect and the battery pack 300 can be dropped off.

[0106] As an example, the connection component 2001 can be a bolt.

[0107] In some examples, the battery pack 300 further includes a refrigerant plug connector, which can be connected via the connection assembly 2001 , thereby enabling connection and disconnection of the battery pack 300 under the action of the blasting unit 600 .

[0108] In some embodiments, as Figure 14 As shown, the vehicle control system 2000 also includes a second detection unit 700 for detecting whether the battery pack 300 has fallen off, and the second detection unit 700 is electrically connected to the control unit 500; the control unit 500 is also used to: when the vehicle body 200 is in a stationary state, control the vehicle body 200 not to move and unlock the vehicle lock based on the fact that the battery pack 300 has not fallen off.

[0109] In some embodiments, as Figure 14 As shown, the vehicle control system 2000 further includes a second detection unit 700 for detecting whether the battery pack 300 has fallen off. The second detection unit 700 is electrically connected to the control unit 500. The control unit 500 is further configured to: when the vehicle body 200 is in motion, based on the fact that the battery pack 300 has not fallen off, control the vehicle body 200 to decelerate, and unlock the vehicle when the deceleration falls below a preset vehicle speed. For example, the preset vehicle speed may be 10 km / h.

[0110] After the car lock is opened, the people inside the car can open the door and escape.

[0111] In some embodiments, the control unit 500 is further used to start the backup battery based on the detachment of the battery pack 300. Driven by the backup battery, the vehicle can stay away from the battery pack in thermal runaway, thereby avoiding being ignited by the battery pack.

[0112] In some examples, the second detection unit 700 may be a plurality of tire pressure sensors, which can determine whether the battery pack 300 has fallen off the vehicle body 200 by detecting changes in tire pressure.
