Description

Technical Field

[0001] The present application relates to the technical field of automobile accessories, and in particular to a vehicle power battery disconnection device and a vehicle. Background Art

[0002] With the popularity of electric vehicles, the safety of vehicle batteries has become increasingly prominent. In actual applications, batteries may spontaneously ignite for a variety of reasons while driving or parking, which will not only burn the vehicle but also cause harm to people around. At present, most emergency release devices on the market use a buckle fixing method, but this method has obvious shortcomings.

[0003] Current detachment devices are often designed to allow batteries to fall off freely under the action of gravity. This method is not only uncontrollable, but may also cause the battery to collide with other parts of the vehicle during the detachment process, causing secondary damage. What's more serious is that when the battery spontaneously combusts, its temperature will rise sharply and enter an abnormally high temperature state. If the battery is subjected to external impact or other forms of impact at this time, it may accelerate combustion or even cause an explosion, greatly increasing the difficulty and danger of accident handling. Moreover, there is a risk of unhooking in the hook fixing method. In an emergency, if the hook is not firmly fixed, the battery may not be able to detach smoothly, thereby delaying the best time for emergency treatment. Therefore, for the emergency treatment of vehicle battery spontaneous combustion, the existing detachment device has obvious shortcomings and cannot effectively deal with the problem of free falling of the battery and the risk of unhooking of the hook fixing. Utility Model Content

[0004] The purpose of the present application is to provide a vehicle power battery detachment device to solve the problem of uncontrollable battery detachment in the battery detachment device in the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted in this application is as follows:

[0006] A vehicle power battery detachment device comprises: a controller for controlling the operation of the vehicle power battery detachment device, an actuator for making the power battery land smoothly, and a battery supporting structure; the controller is electrically connected to the actuator, and the actuator is connected to the battery supporting structure via a connecting structure.

[0007] According to the above-mentioned technical means, since the controller and the actuator are electrically connected, upon receiving the power battery detachment command, the actuator and the battery supporting structure can be controlled to perform the power battery detachment operation. The actuator can control the speed at which the power battery falls off so that the power battery lands smoothly. Compared with the prior art, the present application can control the speed at which the power battery falls off, avoid accidents caused by the free falling of the power battery, and reduce the danger caused by the free falling of the power battery.

[0008] Furthermore, the actuator includes: an actuator body and a lifting link arranged on the actuator body; one end of the lifting link is inserted into the interior of the actuator body, and the other end of the lifting link is exposed outside the actuator body; the actuator body is electrically connected to the lifting link to control the lifting link to rise or fall in a direction perpendicular to the ground.

[0009] According to the above technical means, the actuator body of the actuator controls the lifting link to move up and down in a direction perpendicular to the ground, thereby controlling the speed at which the power battery falls off, so that the power battery lands smoothly.

[0010] Furthermore, the connection structure is a movable unhooking; the movable unhooking is arranged at one end of the lifting connecting rod exposed outside the executing body; the movable unhooking is electrically connected to the executing body, and the executing body controls the movable unhooking to open or close.

[0011] According to the above technical means, by setting an active unhooking electrically connected to the actuator body of the actuator on the lifting link, after the power battery lands on the ground, the actuator body controls the active unhooking to open, so that the lifting link can rise in a direction perpendicular to the ground, thereby achieving a smooth landing of the power battery.

[0012] Furthermore, a position sensor is provided at one end of the lifting link exposed outside the execution body, and the position sensor is used to detect the height of the lifting link from the ground.

[0013] According to the above technical means, the distance between the lifting link and the ground is detected in real time by the position sensor, so that the relative position relationship between the power battery and the ground can be determined, which helps to control the landing speed of the power battery so that the power battery can finally land smoothly.

[0014] Furthermore, the battery supporting structure is a battery tray; the battery tray includes: a connecting part connected to the actuator and a supporting part supporting the battery; a through hole is provided on the connecting part, and the connecting structure connects the actuator and the battery supporting structure through the through hole; the supporting part is provided with a heat dissipation hole.

[0015] According to the above technical means, the battery tray supports the power battery and is connected to the actuator. When the lifting rod of the actuator moves up and down, the battery tray also moves up and down, thereby achieving the effect of controlling the power battery from falling off. In addition, heat dissipation holes are provided on the battery tray, which is beneficial to the heat dissipation of the power battery and avoids power battery failure or danger caused by poor heat dissipation.

[0016] Furthermore, the battery tray is an integrated groove structure, or a groove structure composed of at least two identical support plates, wherein the upper side of each support plate includes a connecting portion and a supporting portion.

[0017] According to the above technical means, a groove structure is set on the battery tray to limit the power battery. During the power battery falling off process, it helps to prevent the power battery from moving or falling from the battery tray, thereby avoiding the danger caused by the battery falling. At the same time, the battery tray can be suitable for batteries of various specifications, which is more practical.

[0018] Furthermore, the actuator and the battery supporting structure are also connected by a magnetic attraction structure; the magnetic attraction structure includes: a first electromagnetic structure arranged on the actuator and a second electromagnetic structure arranged on the battery supporting structure.

[0019] Furthermore, the magnetic attraction structure is electrically connected to the controller.

[0020] According to the above technical means, a magnetic attraction structure is provided between the actuator and the battery supporting structure to perform secondary reinforcement on the connection between the actuator and the battery supporting structure, thereby effectively avoiding the problem of unhooking caused by using a single connection structure for connection.

[0021] Furthermore, the actuator is also provided with a fixing component for fixing to the vehicle body.

[0022] According to the above technical means, the vehicle power battery separation device is fixed to the vehicle body using a fixing assembly, which is easy to install and maintain.

[0023] A car comprises a car body, wherein the car body is provided with a vehicle power battery release device.

After the controller receives the power battery detachment instruction, the actuator and the battery fixing mechanism are controlled to perform the power battery detachment operation. Since the actuator can control the speed at which the power battery falls off, the power battery lands smoothly, which solves the problem of uncontrollable battery detachment in the vehicle battery detachment device in the prior art.

DETAILED DESCRIPTION

[0032] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0033] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0034] For ease of description, spatial relative terms may be used in the text to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a change in posture or a change in motion state, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented to "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0035] Current detachment devices are often designed to allow batteries to fall off freely under the action of gravity. This method is not only uncontrollable, but may also cause the battery to collide with other parts of the vehicle during the detachment process, causing secondary damage. What is more serious is that when the battery spontaneously combusts, its temperature will rise sharply and enter an abnormal high temperature state. If the battery is subjected to external impact or other forms of impact at this time, it may accelerate combustion or even cause an explosion, greatly increasing the difficulty and danger of accident handling. In order to solve the technical problem that the battery detachment of the vehicle in the prior art is uncontrollable, the present application provides a vehicle power battery detachment device that can control the power battery to land smoothly.

[0036] See also Figure 1 , Figure 1 This is a front view of the vehicle power battery release device of the present application, as shown Figure 1 As shown, a vehicle power battery detachment device provided in an embodiment of the present application includes: a controller 1 for controlling the operation of the vehicle power battery detachment device, an actuator 2 for making the power battery land smoothly, and a battery supporting structure 3; the controller 1 is electrically connected to the actuator 2, and the actuator 2 is connected to the battery supporting structure 3 via a connecting structure 23.

[0037] It can be understood that since the controller and the actuator are electrically connected, when a power battery detachment command is received, the actuator and the battery supporting structure can be controlled to perform the power battery detachment operation. The actuator can control the speed at which the power battery falls off so that the power battery lands smoothly. Compared with the prior art, the present application can control the speed at which the power battery falls off, avoid accidents caused by the free falling of the power battery, and reduce the danger caused by the free falling of the power battery.

[0038] In specific practice, the controller can be set together with the actuator and connected to the vehicle control system, and the actuator and power battery position, status and other information can be fed back to the vehicle controller through CAN (Controller Area Network) in real time. The vehicle controller determines whether the power battery is abnormal based on the above information, and sends a power battery separation instruction to the vehicle power battery separation device when the power battery is abnormal. As an optional embodiment, Figure 1 As shown, the controller 1 can be arranged on one side of the actuator. As another optional embodiment, the controller can also be arranged separately from the actuator.

[0039] In order to achieve a smooth landing effect of the power battery, in this embodiment, the actuator 2 is used to control the speed of the power battery detachment. As an optional embodiment, Figure 1 As shown, the actuator 2 includes: an actuator body 21 and a lifting link 22 arranged on the actuator body 21; one end of the lifting link 22 is deeply inserted into the interior of the actuator body 21, and the other end of the lifting link 22 is exposed outside the actuator body 21; the actuator body 21 is electrically connected to the lifting link 22, and is used to control the lifting link 22 to rise or fall in a direction perpendicular to the ground.

[0040] It can be understood that the actuator body of the actuator controls the lifting link to move up and down in a direction perpendicular to the ground, thereby controlling the speed at which the power battery falls off, so that the power battery lands smoothly.

[0041] In specific practice, the vehicle power battery separation device sends a lifting link lowering command to the actuator, and the actuator will control the lifting link to descend; when the battery supporting structure is close to the ground, the vehicle power battery separation device sends a lifting link lowering speed reduction command to allow the power battery to land slowly and smoothly; when the battery supporting structure reaches the ground, the vehicle power battery separation device sends a lifting link stop descending command to disconnect the battery supporting structure from the lifting link; after the connection is disconnected, the vehicle power battery separation device sends a lifting link rising command, and when the lifting link rises to its original position, it stops rising, and the power battery separation is completed.

[0042] It should be noted that in order to make the abnormal power battery fall off as soon as possible, the lowering speed of the lifting link is faster in the early stage of the descent; in order to make the power battery land slowly and smoothly, the lowering speed of the lifting link can be slower than the previous lowering speed. It can be understood that by controlling the lowering speed of the lifting link, it is ensured that the power battery is separated from the vehicle as soon as possible and that the power battery lands slowly and smoothly, effectively avoiding accidents caused by the free fall of the power battery and reducing the danger caused by the free fall of the power battery.

[0043] In this embodiment, the power battery is connected to the actuator by means of the battery support structure. When the actuator has controlled the lifting link to descend so that the battery support structure falls to the ground, the lifting link and the battery support structure are still connected. Therefore, a controllable connection structure is required to disconnect the lifting link and the battery support structure. Figure 1 As shown, the connection structure 23 is a movable unhooking; the movable unhooking is arranged at one end of the lifting link 22 exposed outside the execution body 21; the movable unhooking is electrically connected to the execution body 21, and the execution body 21 controls the movable unhooking to open or close.

[0044] It can be understood that by setting a movable decoupling electrically connected to the actuator body of the actuator on the lifting link, after the power battery lands on the ground, the actuator body controls the movable decoupling to open, so that the lifting link can rise in a direction perpendicular to the ground, thereby achieving a smooth landing of the power battery.

[0045] In specific practice, when the battery support mechanism reaches the ground, the vehicle power battery disengagement device sends an active disengagement opening command, and the active disengagement opens at this time; when the active disengagement opens, the battery support mechanism is disconnected from the lifting link, and the power battery is in a disengaged state; the vehicle power battery disengagement device feeds back the disengagement state of the power battery to the vehicle controller, and sends a lifting link rising command at the same time. When the lifting link rises to the original position, it stops rising, and the power battery is disengaged. It should be noted that in this embodiment, if Figure 1 As shown, the current fixed part of the active unhook is unfolded, and the unfolded shape is similar to the shape of an inverted umbrella after opening, which can achieve the function of fixing and connecting the battery tray. Therefore, the active unhook is closed at this time. The corresponding active unhook opening refers to the closure of the fixed part of the active unhook, and the closed shape is similar to the shape of an umbrella after closing. During the lifting process of the lifting connecting rod, the active unhook can be opened or closed. It can be understood that by controlling the opening or closing of the active unhook, it is ensured that when the power battery is normal, the battery supporting mechanism can be effectively fixed, and when the power battery is abnormal, it is ensured that the connection with the battery supporting mechanism can be disconnected in time to make the power battery detached.

[0046] In order to better control the descending speed of the lifting link, in this embodiment, a position sensor is used to detect the height of the lifting link from the ground. Figure 1 As shown, a position sensor 24 is also provided at one end of the lifting link 22 exposed outside the actuator body 21 , and the position sensor 24 is used to detect the height of the lifting link 22 from the ground.

[0047] It can be understood that by detecting the distance between the lifting link and the ground in real time through the position sensor, the relative position relationship between the power battery and the ground can be determined, which in turn helps to control the landing speed of the power battery so that the power battery finally lands smoothly.

[0048] In order to control the power battery shedding speed, in this embodiment, a battery supporting structure is provided for the power battery and used in conjunction with an actuator to control the power battery shedding speed. Figure 1 As shown, the battery supporting structure 3 is a battery tray; the battery tray includes: a connecting portion 31 connected to the actuator 2 and a supporting portion 32 supporting the battery; a through hole 33 is provided on the connecting portion, and the connecting structure 23 connects the actuator 2 and the battery supporting structure 3 through the through hole 33; the supporting portion 32 is provided with a heat dissipation hole.

[0049] It can be understood that the battery tray supports the power battery and is connected to the actuator. When the lifting rod of the actuator moves up and down, the battery tray also moves up and down, thereby achieving the effect of controlling the power battery from falling off. In addition, heat dissipation holes are provided on the battery tray, which is beneficial to the heat dissipation of the power battery and avoids power battery failure or danger caused by poor heat dissipation.

[0050] In order to prevent the power battery from moving during the falling process, in this embodiment, a groove is provided in the battery supporting structure to limit the movement of the power battery. As an optional embodiment, the battery tray is an integrated groove structure, the connecting portion 31 and the supporting portion 32 are an integrated structure, the supporting portion 32 is a groove, the movement of the power battery is limited by the groove, and the connecting portion 31 is respectively provided with a through hole 33 and a second electromagnetic structure 42.

[0051] It is understandable that a groove structure is provided on the battery tray to limit the power battery. During the power battery falling-off process, it helps to prevent the power battery from moving or falling off the battery tray, thereby avoiding the danger caused by the falling battery.

[0052] Considering that there are various specifications and models of power batteries in actual applications, in order to apply more power batteries, in this embodiment, a battery support structure with a groove is formed by splicing. As an optional embodiment, the battery tray is a groove structure composed of at least two identical support plates, wherein each support plate includes a connecting portion and a supporting portion. In this embodiment, if Figure 1As shown, the battery tray is composed of two identical support plates, each of which is provided with a connecting portion 31 and a supporting portion 32, and a through hole 33 and a second electromagnetic structure 42 are respectively provided on the connecting portion. The supporting portions of the two support plates are spliced ​​to form a groove, and the movement of the power battery is restricted by the groove. Since the supporting portions of the two support plates are spliced ​​to form a groove, the size of the groove can be adjusted according to the size of the power battery, so that it can be suitable for power batteries of various specifications and models.

[0053] It is understandable that a groove structure is provided on the battery tray to limit the power battery. During the power battery falling off process, it helps to prevent the power battery from moving or falling off the battery tray, thereby avoiding the danger caused by the falling battery. At the same time, the battery tray can be suitable for batteries of various specifications, which is more practical.

[0054] In specific practice, in order to prevent the power battery from moving during the falling process, the power battery can also be fixed to the battery supporting structure through a fixing structure, and the fixing structure includes but is not limited to the following structures: bolts and nuts, adhesives, clamps, etc.

[0055] Since the hook fixing method in the above embodiment has the risk of unhooking, in an emergency, if the hook is not firmly fixed, the power battery may not be able to be smoothly detached, thereby delaying the best time for emergency treatment. In this embodiment, on the basis of the hook fixing method, a magnetic structure is added between the actuator and the battery supporting structure, and the connection between the actuator and the battery supporting structure is further strengthened by the magnetic structure. As an optional embodiment, Figure 1 As shown, the actuator 2 and the battery support structure 3 are also connected by a magnetic structure 4; the magnetic structure 4 includes: a first electromagnetic structure 41 arranged on the actuator 2 and a second electromagnetic structure 42 arranged on the battery support structure 3. Further, the magnetic structure 4 is electrically connected to the controller 1.

[0056] In actual practice, in order to make the connection between the actuator and the battery supporting structure more secure, a plurality of magnetic structures are usually provided, each of which is composed of a first electromagnetic structure and a second electromagnetic structure.

[0057] It can be understood that by providing a magnetic attraction structure between the actuator and the battery supporting structure, the connection between the actuator and the battery supporting structure is reinforced, which effectively avoids the problem of unhooking caused by using a single connection structure for connection.

[0058] In specific practice, the magnetic attraction structure is an electromagnetic lock, the lock body of the electromagnetic lock is a first electromagnetic structure, which is installed on the actuator body of the actuator, and the lock tongue of the electromagnetic lock is a second electromagnetic structure, which is installed on the connection part of the battery support structure. In order for the electromagnetic lock to work properly, the installation position and spacing of the lock body and lock tongue of the electromagnetic lock need to be installed in accordance with the specifications. The lock tongue is usually made of ferromagnetic material and can be attracted by the magnetic force generated by the electromagnet. The lock body provides the moving space and locking position of the lock tongue. The locking and unlocking of the electromagnetic lock are usually achieved by controlling the current on and off of the electromagnet. In the locked state, the electromagnet is energized to generate magnetic force to attract the lock tongue to achieve locking; in the unlocked state, the electromagnet is de-energized, the magnetic force disappears, and the lock tongue returns to its original position under the action of the reset mechanism to achieve unlocking.

[0059] In this embodiment, when the vehicle power battery is normal, the vehicle power battery disengagement device will send an electromagnetic lock locking instruction to put the electromagnetic lock in a locked state. When the electromagnetic lock is in the locked state, the electromagnet is energized to generate magnetic force to attract the lock tongue, and the lock body and the lock tongue are attracted to connect the battery support structure and the actuator. When the vehicle power battery is abnormal, the vehicle power battery disengagement device will send an electromagnetic lock unlocking instruction to put the electromagnetic lock in an unlocked state. When the electromagnetic lock is in the unlocked state, the electromagnet is powered off, the magnetic force disappears, the lock tongue returns to its original position under the action of the reset mechanism, and the lock body and the lock tongue suction disappears, so that the battery support structure and the actuator are disconnected.

[0060] It can be understood that the battery supporting structure is doubly fixed by the electromagnetic lock and the movable unhooking, thereby preventing the battery supporting structure from accidentally detaching due to a single fixing method.

[0061] As an optional embodiment, the actuator 2 is also provided with a fixing assembly 25 for fixing to the vehicle body. Figure 2 , Figure 2 This is a top view of the vehicle power battery detachment device of the present application, as shown Figure 2 As shown, the vehicle power battery detachment device comprises an integrated battery support structure 3, four actuators 2, and a controller 1, wherein the controller 1 is arranged on one side of one of the actuators 2, and each actuator 2 is provided with a fixing component 25 fixed to the vehicle body. In this embodiment, the fixing component 25 has a fixing hole, which is used in conjunction with a screw to fix the vehicle power battery detachment device to the vehicle body.

[0062] It can be understood that the vehicle power battery disconnect device is fixed to the vehicle body using a fixing assembly, which is easy to install and maintain.

[0063] In actual practice, when the vehicle's power battery is in an abnormal state and the vehicle controller needs to detach the power battery, the power battery detachment command is sent to the vehicle's power battery detachment device via CAN (Controller Area Network). The vehicle's power battery detachment device issues an electromagnetic lock unlocking command. Upon receiving feedback from the electromagnetic lock that it has been unlocked, the vehicle's power battery detachment device issues a lifting link lowering command to the actuator, and the actuator controls the lifting link to descend. At the same time, the position sensor continuously detects the distance between the lifting link and the ground in real time. When the battery tray approaches the ground, the vehicle's power battery detachment device issues a lifting link lowering speed reduction command. When the battery tray reaches the ground (when it reaches the ground, the status of the vehicle's power battery detachment device, please refer to Figure 3 ), the vehicle power battery disengagement device issues a command for the lifting link to stop descending and an instruction for the active disengagement to open. The lifting link stops descending and the active disengagement opens at the same time. When the active disengagement opens, the battery tray is disconnected from the lifting link, and the power battery is in a disengaged state; the vehicle power battery disengagement device feeds back the disengagement state of the power battery to the vehicle controller and sends a command for the lifting link to rise. When the lifting link rises to its original position, it stops rising and the power battery is disengaged (when the battery is disengaged, please refer to the status of the vehicle power battery disengagement device for details). Figure 4 ). When the power battery is abnormal or has fallen off, the vehicle power battery disconnection device is powered by the vehicle emergency battery.

[0064] An embodiment of the present application also provides a car, including a car body, on which is provided a vehicle power battery detachment device in the above embodiment. When the power battery is abnormal, the vehicle power battery detachment device is used to make the power battery land smoothly.

[0065] It is understandable that when the vehicle's power battery is in an abnormal state, if the vehicle controller needs to detach the power battery, the detachment instruction will be sent to the vehicle power battery detachment device through the CAN network. The vehicle power battery detachment device controls the actuator and the battery supporting mechanism to perform the battery detachment operation, and finally the power battery falls to the ground slowly and smoothly, effectively avoiding accidents caused by the free fall of the power battery and reducing the danger caused by the free fall of the power battery.
