Description

TECHNICAL FIELD

[0001] The utility model relates to an automatic disconnecting device for connector more specifically, relate to an automatic disconnecting device for connector, it can be applied to electric vehicle to be able to automatically disconnect the battery connector in electric vehicle when needing to realize the high voltage battery power off in physics. BACKGROUND

[0002] Internal combustion engines have long been used as the main power source for vehicles such as cars. The fuel of internal combustion engines is mainly fossil energy, which will emit greenhouse gases during combustion and cause environmental problems such as global warming. In addition, fossil energy reserves are limited, so it is crucial to develop alternative energy sources.

[0003] With the progress of large-capacity battery technology, the improvement of motor performance, and the continuous research and development of auxiliary driving technology, electric vehicles are gradually replacing internal combustion engine vehicles.

[0004] However, there is still room for improvement in the safety of high-voltage batteries in electric vehicles. For example, in the event of a collision of an electric vehicle, if the positive and negative poles of the high-voltage line connected to the high-voltage battery are short-circuited by the vehicle body (such as the vehicle body sheet metal), it will cause the high-voltage battery to discharge rapidly, which may cause temperature runaway and even cause a fire, thereby threatening the safety of passengers.

[0005] In the related art, when a collision occurs, the electric vehicle can cut off the power supply of the high-voltage battery through the battery management system (BMS). However, this cutting method has the possibility of failure, because if the positive and negative poles of the high-voltage line connected to the high-voltage battery are short-circuited by the vehicle body, a very large instantaneous current will be generated, which may cause the contact point inside the high-voltage relay used to cut off the high-voltage power to stick together, so that the BMS cannot disconnect the high-voltage power by controlling the high-voltage relay.

[0006] Therefore, there is still room for improvement in the safety of high-voltage batteries.

[0076] Hereinafter, the structure of the automatic disconnecting device for connectors of the present application will be described in detail in conjunction with the accompanying drawings.

[0077] The automatic disconnecting device for connectors of the present application can include a base plate 1, a bracket assembly 2, a guide assembly 3, a moving piece 4, a locking unit 5, and a driving unit 6.

[0078] Referring to Figures 1 to 7 The base plate 1 is a plate-shaped element, and includes a base plate body 11, a first stepped portion 12, and a second stepped portion 13, the base plate body 11 is protruded with respect to the first stepped portion 12 and the second stepped portion 13 to form an assembly space 10, the assembly space 10 is configured to make the installation and movement of the moving piece 4 to be described in detail below more smooth, and to make the moving piece 4 not interfere with the base plate body 11. Referring to Figure 6 The base plate body 11 and the moving piece 4 are spaced apart from each other. In addition, the base plate 1 can be formed as a part of a vehicle body of an electric vehicle.

[0079] Alternatively, the base plate 1 can be a separate plate-shaped element, and can be installed to a vehicle body of an electric vehicle. In addition, the position of the base plate 1 is designed such that the wire harness end connector 100 installed thereon can be electrically connected with the high-voltage battery end connector 200.

[0080] The bracket assembly 2 can be mounted to the base plate 1 and can include a first bracket 21 and a second bracket 22 which are parallel to each other and spaced apart by a predetermined distance. In detail, the first bracket 21 can be mounted to the first stepped portion 12 by a bolt, and the second bracket 22 can be mounted to the second stepped portion 13 by a bolt. However, it will be understood by those skilled in the art that the mounting method of the first bracket 21 and the second bracket 22 is not limited thereto, and any other method capable of achieving the same technical effect can be used, which will not be described hereinafter.

[0081] The guide assembly 3 can be located between and connected to the first bracket 21 and the second bracket 22.

[0082] According to the exemplary embodiment of the present application, the guide assembly 3 can include a first guide 31 and a second guide 32 which are arranged parallel to each other and spaced apart by a predetermined distance. In the illustrated example, the first guide 31 and the second guide 32 are formed as rods having a circular cross-section.

[0083] Although the guide assembly 3 shown in the exemplary embodiment includes two guides, and both guides are formed to have a circular cross-section, it will be understood by those skilled in the art that the number of guides and the cross-sectional shape are not limited thereto. For example, in other examples, the number of guides can be one, or more than two (e.g., three), and the cross-sectional shape of the guides can also be variously changed, such as a constant prismatic cross-section, etc.

[0084] The moving member 4 is movably mounted to the guide assembly 3. In the illustrated example, the moving member 4 can include a first guide portion 41 and a second guide portion 42, and the first guide portion 41 can include a first guide hole 411 through which the first guide 31 can pass, and the second guide portion 42 can include a second guide hole 421 through which the second guide 32 can pass. Among them, the first guide hole 411 and the second guide hole 421 can be designed to cooperate with the first guide 31 and the second guide 32, respectively, so that the moving member 4 can move along the first guide 31 and the second guide 32, and accordingly, the movement trajectory of the moving member 4 can be defined by the first guide 31 and the second guide 32.

[0085] Accordingly, according to the exemplary embodiment of the present application, the first guide hole 411 and the second guide hole 421 are formed to have a circular cross-section, and the inner diameter size of the first guide hole 411 and the second guide hole 421 is equal to or slightly larger than the outer diameter size of the first guide 31 and the second guide 32.

[0086] In particular, although the guiding assembly 3 and the moving member 4 are assembled in a manner of cooperation of the guiding hole and the guide in the exemplary embodiment of the present application, it should be understood by those skilled in the art that the assembly manner of the guiding assembly 3 and the moving member 4 is not limited thereto, and any other manner capable of achieving the same technical effect can be used.

[0087] For example, in one variant embodiment, the guiding assembly can include a guiding rail, and the moving member can include a slider, wherein the slider can move or slide along the guiding rail, and in this way, the same technical effect as the structure in the exemplary embodiment of the present application can be achieved.

[0088] For example, in another variant embodiment, the guiding assembly can be formed integrally with the base plate rather than a separate assembly. Similarly, the guiding assembly and the moving member can be assembled in a manner of cooperation of the guiding rail and the slider. It should be understood that those skilled in the art can make various modifications or replacements under the teachings disclosed in the present application, and such modifications or replacements fall within the protection scope of the claims of the present application.

[0089] Further, according to the exemplary embodiment of the present application, the locking unit 5 can be mounted to the base plate 1, and the locking unit 5 can be configured to selectively lock or unlock the moving member 4. That is, the locking unit 5 can switch the moving member 4 between a movable state and an immovable state.

[0090] The driving unit 6 can be mounted to the base plate 1 and connected to the moving member 4, and the driving unit 6 can apply a driving force to the moving member 4 to move the moving member 4. Specifically, when the locking unit 5 unlocks the moving member 4, the driving unit 6 can move the moving member 4 along the guiding assembly 3.

[0091] More specifically, the locking unit 5 can include a first actuator 51 mounted to the base plate 1 and a telescopic rod 52 connected to the first actuator 51 and configured to extend or retract based on the operation of the first actuator 51.

[0092] Correspondingly, the moving member 4 can further include a locking portion 43 located at the top of the moving member 4 and including a locking hole 431, and the telescopic rod 52 is selectively inserted into or detached from the locking hole 431 in response to the operation of the first actuator 51.

[0093] In the illustrated example, the locking unit 5 and the driving unit 6 can be located on the upper and lower sides of the base plate 1, respectively, that is, the locking unit 5 can be located on the upper side of the base plate 1, and the driving unit 6 can be located on the lower side of the base plate 1.

[0094] In this case, the substrate 1 can include a through hole (not shown) corresponding to the position of the telescopic rod 52, so that when the telescopic rod 52 is extended, the free end of the telescopic rod 52 can be inserted into the locking hole 431 through the through hole of the substrate 1, thereby the moving piece 4 can be locked to avoid the moving piece 4 from being displaced undesirably, and also can be used to determine whether the moving piece 4 has been moved into position.

[0095] As an example, when the device of the utility model is applied to the application scenario of the wire harness end connector 100 and the high-voltage battery end connector 200, the wire harness end connector 100 can be installed or fixed to the moving piece 4. In this case, the cooperation of the telescopic rod 52 and the locking hole 431 can be used to determine whether the wire harness end connector has been connected to the high-voltage battery end connector, thereby the reliability of the power supply line of the high-voltage battery can be ensured.

[0096] As shown in the figure, the telescopic rod 52 can be formed in a cylindrical shape, accordingly, the locking hole 431 and the through hole of the substrate 1 can be formed in a circular cross section, and the inner diameter of the locking hole 431 and the through hole of the substrate 1 can be greater than or equal to the outer diameter of the telescopic rod 52. However, it should be understood by those skilled in the art that the shape of the telescopic rod and the shape of the locking hole and the through hole are not limited thereto. In addition, although the number of telescopic rods shown in the example is two, it should be understood that the number of telescopic rods is not limited thereto, any other number can be, and the number of locking holes and through holes corresponds to the number of telescopic rods.

[0097] In the exemplary embodiment, the first actuator 51 can be an electric motor. In particular, the first actuator 51 can be a bidirectional electric motor, and the first actuator 51 can be installed to the substrate body 11, which will be described with reference to Figure 6 .

[0098] In this case, when the first actuator 51 rotates in the first direction, the telescopic rod 52 can be extended to pass through the through hole of the substrate 1 to be inserted into the locking hole 431, at this time, the moving piece 4 is in a locked state; while when the first actuator 51 rotates in the second direction, the telescopic rod 52 can be retracted to be separated from the locking hole 431, at this time, the moving piece 4 is in an unlocked state, i.e. the moving piece 4 can be moved along the guide assembly 3 by the applied driving force, wherein the second direction is opposite to the first direction. Conversely, the state of the telescopic rod corresponding to the rotation direction of the first actuator is not limited thereto, which will not be described herein.

[0099] In the following, the driving unit 6 of the utility model will be described in detail with reference to the accompanying drawings.

[0100] According to the exemplary embodiment of the present application, the driving unit 6 can include a second actuator 61, a lead screw 62, and first and second bearings 63 and 64, wherein the second actuator 61 can be mounted to the base plate 1; the lead screw 62 can be disposed in parallel with the guide assembly 3, the lead screw 62 being connected to the second actuator 61 and the moving member 4 and configured to rotate in a first direction or a second direction based on an operation of the second actuator 61; and the first and second bearings 63 and 64 are respectively located at opposite ends of the lead screw 62, and the first and second bearings 63 and 64 are respectively mounted in the first and second brackets 21 and 22, such that the lead screw 62 is rotatably mounted to the first and second brackets 21 and 22.

[0101] In detail, the lead screw 62 can be located between and in parallel with the first and second guides 31 and 32. The second actuator 61 can be mounted to the first stepped portion 12 of the base plate 1 by bolt connection. However, it should be understood by those skilled in the art that the mounting manner of the second actuator 61 is not limited thereto.

[0102] Correspondingly, the moving member 4 can further include a connecting portion 44, the lead screw 62 can pass through the connecting portion 44, and the connecting portion 44 has internal threads matched with external threads on an outer circumferential surface of the lead screw 62, the connecting portion 44 being located between and connected with the first and second guide portions 41 and 42.

[0103] In the illustrated example, the connecting portion 44, the first guide portion 41, and the bottom of the second guide portion 42 are connected to form a flat bottom surface, and the wire harness end connector 100 can be connected to the flat bottom surface of the moving member 4, for example, by bolt connection.

[0106] For example, when the second actuator 61 rotates in a second direction, the lead screw 62 connected to the second actuator 61 also rotates in the second direction, at this time, the moving member 4 and the wire harness end connector 100 connected to the moving member 4 can move in a direction away from the high-voltage battery end connector 200, accordingly, the wire harness end connector and the high-voltage battery end connector can be physically separated; while when the second actuator 61 rotates in a first direction, the lead screw 62 connected to the second actuator 61 also rotates in the first direction, at this time, the moving member 4 and the wire harness end connector 100 connected to the moving member 4 can move in a direction close to the high-voltage battery end connector 200 until the wire harness end connector 100 and the high-voltage battery end connector 200 are electrically connected, wherein the second direction is opposite to the first direction. Conversely, the moving direction of the moving member corresponding to the rotating direction of the second actuator is not limited thereto, which will not be described herein.

[0108] In the illustrated example, the first bracket 21 is installed to the first stepped portion 12 of the substrate 1, and the second bracket 22 is installed to the second stepped portion 13 of the substrate 1. Specifically, the first bracket 21 and the second bracket 22 can be installed to the substrate 1 by bolt connection, but are not limited thereto. In addition, in order to match the shapes of the first guide 31 and the second guide 32, the first insertion hole 212, the second insertion hole 213, the third insertion hole 222, and the fourth insertion hole 223 can be formed to have a circular cross section. With reference to Figure 4 and Figure 5 , the first bracket 21 and the second bracket 22 can be substantially a right "m" shape.

[0109] Preferably, the first bearing 63 installed in the first mounting hole 211 and the second bearing 64 installed in the second mounting hole 221 can be ball bearings, and the shape and size of the first mounting hole 211 and the second mounting hole 221 can be configured to cooperate with the first bearing 63 and the second bearing 64, respectively. However, those skilled in the art will understand that the type of the first bearing 63 and the second bearing 64 is not limited thereto.

[0110] The utility model also relates to an electric vehicle which can include the automatic disconnecting device for connector as described above. Accordingly, when the electric vehicle collides or needs to replace the high-voltage battery, the wire harness end connector and the high-voltage battery end connector can be automatically and physically separated, thereby the safety of the high-voltage battery can be improved.

[0111] In particular, in addition to the automatic disconnecting device for connector as described above, the electric vehicle can further include a safety system (not shown) which can be configured to control the automatic disconnecting device for connector based on the current state of the electric vehicle or the driver input.

[0112] In order to make those skilled in the art more clearly understand the safety system in the electric vehicle and the process of controlling the automatic disconnecting device for connector by the safety system to perform the disconnecting operation or the connecting operation, the following will be described.

[0113] The following will be described in more detail the process of controlling the automatic disconnecting device by the safety system in the electric vehicle to perform the disconnecting operation.

[0114] For example, the safety system in the electric vehicle can include an airbag controller (ACU) and a controller (ECU), wherein the ACU is electrically connected to the ECU, and the ECU is electrically connected to the locking unit and the driving unit in the automatic disconnecting device of the utility model.

[0115] When the electric vehicle collides, the airbag controller (ACU) can send a signal to the controller (ECU); after the ECU receives the signal, the operation of the locking unit can be controlled, i.e., the first actuator is actuated, the telescopic rod is retracted, so that the free end of the telescopic rod can be separated from the locking hole, at this time the moving piece is in a movable state; at the same time, the ECU can control the operation of the driving unit, i.e., the second actuator is actuated, the lead screw rotates in the first direction or the second direction, so that the moving piece and the wire harness end connector connected to the moving piece move towards the direction away from the high-voltage battery end connector, accordingly, the wire harness end connector and the high-voltage battery end connector can be physically separated, thereby the power of the high-voltage battery can be reliably disconnected, and thus the safety of the high-voltage battery can be improved.

[0116] In addition, the safety system in the electric vehicle can further comprise a central control operation unit, wherein the central control operation unit is electrically connected with the ECU, and the central control operation unit can comprise a central control screen and a central control controller.

[0117] When the battery in the electric vehicle needs to be replaced, the driver clicks the "replace battery" option on the central control screen, accordingly, the central control controller can send a signal to the ECU; after the ECU receives the signal, it can control the operation of the locking unit, and at the same time, the ECU can control the operation of the driving unit, wherein the specific operation of the locking unit and the driving unit is as described above, which will not be repeated here; similarly, the wire harness end connector and the high-voltage battery end connector can be physically separated, at which time the relevant operating personnel can safely replace the battery.

[0118] Next, when it is necessary to reconnect the wire harness end connector and the high-voltage battery end connector, for example, when the battery has been replaced, the driver can click the "battery replacement complete" or "connect battery" option on the central control screen, accordingly, the central control controller can send a signal to the ECU; after the ECU receives the signal, it can control the operation of the driving unit, that is, the second actuator is actuated, the lead screw rotates in the second direction or the first direction, so that the moving piece and the wire harness end connector connected to the moving piece can move towards the direction close to the high-voltage battery end connector until the wire harness end connector and the high-voltage battery end connector are connected (i.e. electrically connected) to each other; at the same time, the ECU can control the operation of the locking unit, that is, the first actuator is actuated, the telescopic rod is extended to insert into the locking hole through the through hole of the base plate, at this time the moving piece is in an immovable state, thereby ensuring the reliability of the connection between the wire harness end connector and the high-voltage battery end connector, and avoiding the occurrence of unexpected disconnection.

[0119] Preferably, a position sensor can be provided on the telescopic rod, so as to determine whether the moving piece and the wire harness end connector have been moved into position through the position sensor, and also can be used to determine whether the telescopic rod has been extended into position. Alternatively, similar sensors can also be provided on the moving piece.

[0120] As described above, when the automatic disconnection device for the connector of the utility model is applied to an electric vehicle, automatic connection and disconnection between the wire harness end connector and the high-voltage battery end connector can be achieved, thereby the safety of the high-voltage battery can be significantly improved.

[0121] In addition, when the battery in the electric vehicle is replaced, the risk of electric shock can be effectively avoided, and it is more convenient and fast.
