Description
Technical Field
[0001] This invention relates to the field of battery swapping technology, and in particular to an unlocking lever lifting detection device and a battery swapping equipment. Background Technology
[0002] Existing electric vehicle battery pack installation methods are generally divided into fixed and swappable types. Fixed battery packs are typically fixed to the vehicle, and the vehicle is used as the charging device during charging. Swappable battery packs, on the other hand, are usually installed in a movable manner, allowing the battery pack to be removed and replaced with a new one at any time.
[0003] However, for large vehicles, such as heavy or light trucks, the large vehicle body and cargo weight result in a high demand for battery pack capacity. Sufficiently large electrical capacity is required to support a vehicle's range of over 100 kilometers. Replacing the battery pack requires using battery swapping equipment to unlock and unlock it. However, the battery packs of large vehicles are quite large, while electric vehicles have a lower chassis and insufficient space underneath, especially vertical space. Conventional battery swapping equipment cannot easily access the undercarriage to unlock and unlock the battery pack using its unlocking lever. A lifting and lowering unlocking lever is needed, but it's difficult to ensure that the lever moves correctly and unlocks the battery. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the defect in the prior art that it is difficult to guarantee whether the unlocking rod that can be raised and lowered has moved upward into place, and to provide an unlocking rod lifting detection device and a power swapping device.
[0005] The present invention solves the above-mentioned technical problems through the following technical solution:
[0006] A device for detecting the lifting and lowering of an unlocking lever, applied to a battery swapping device and used to unlock and lower a battery pack on an electric vehicle, is characterized in that the device comprises: an unlocking lever and a drive mechanism, the drive mechanism driving the unlocking lever to move so as to unlock the locking mechanism on the electric vehicle; a first detection element for detecting whether the drive mechanism has moved to a first set position; and a second detection element for detecting whether the unlocking lever has been driven upward by the drive mechanism to a second set position.
[0007] In this invention, the driving mechanism drives the unlocking lever to unlock the battery pack. The first detection element detects the driving mechanism to ensure that the driving structure can be driven into place. The second detection element detects the unlocking lever to ensure that the unlocking lever can move normally and unlock after the driving mechanism moves. The battery pack can only be unlocked when the unlocking lever moves to the second set position. The second detection element detects whether the unlocking lever has moved to the set position to ensure that the unlocking operation is normal.
[0008] Preferably, the drive mechanism is used for horizontal drive to move the unlocking lever up and down.
[0009] In this invention, the up-and-down movement of the unlocking lever can be accomplished by the horizontal movement of the drive mechanism, which helps to lower the height of the unlocking lever lifting detection device, making it easier to access the underside of electric vehicles with different chassis heights.
[0010] Preferably, the driving mechanism includes an unlocking guide block and a driver, the driver being fixedly connected to the unlocking guide block, and the driver being used to drive the unlocking guide block to move in a direction away from the driver to the first set position, so as to drive the unlocking rod to move upward.
[0011] In this solution, the drive mechanism adopts a split design, with a driver that drives the unlocking rod to move through the unlocking guide block. The split design can reduce the accuracy requirements of the installation position between the drive mechanism and the unlocking rod, thereby reducing its production cost.
[0012] Preferably, the unlocking lever lifting detection device further includes a third detection element, which is used to detect that the unlocking guide block moves to a third set position in a direction close to the driver.
[0013] In this solution, the above-mentioned structural form is adopted. The third detection component helps to ensure that the return stroke of the unlocking guide block is not excessive, which helps to protect the structure of the unlocking rod lifting detection device and extend its service life.
[0014] Preferably, the unlocking guide block is provided with an unlocking guide groove, the unlocking guide groove including a first guide portion and a second guide portion. The first setting position is the position of the unlocking guide block when the unlocking rod is driven to the end of the first guide portion away from the second guide portion. The second setting position is set to the position of the side detection position of the unlocking rod when the unlocking rod rises to a set height, the set height being less than or equal to the maximum stroke height of the unlocking rod. The third setting position is the position of the unlocking guide block when the unlocking rod is driven to the end of the second guide portion away from the second guide portion.
[0015] In this solution, the above-mentioned structural form is adopted. The unlocking guide groove includes a first guide part that moves in the same direction as the unlocking guide block and a second guide part that is parallel to the first guide part and located at the lower end of the first guide part. The first guide part and the second guide part ensure that the unlocking guide block can move horizontally and provide horizontal support for the stopping of the protrusion of the unlocking rod. It also includes a third guide part that is inclined downward from the first guide part and connects to the second guide part, ensuring that the protrusion of the locking rod can move up and down.
[0016] Preferably, the unlocking rod lifting detection device further includes a horizontal guide mechanism, which has a horizontal guide groove. The unlocking rod is installed with left and right limits relative to the horizontal guide groove. The horizontal movement of the unlocking guide block in the horizontal guide groove causes the unlocking rod to move up and down relative to the horizontal guide mechanism along the unlocking guide block.
[0017] In this invention, a horizontal guiding mechanism is used to guide and constrain the horizontal movement of the unlocking guide block, thereby ensuring that the unlocking rod moves up and down along the unlocking guide groove to achieve unlocking, thus saving space in the vertical direction.
[0018] Preferably, the unlocking rod lifting detection device further includes a vertical guide groove fixedly disposed in the horizontal guide mechanism, through which the unlocking rod can move up and down.
[0019] In this solution, the above-mentioned structural form is adopted, and a vertical guide mechanism is set up to guide the unlocking rod, so as to ensure that the unlocking rod moves up and down in a predetermined direction and avoids tilting to the left and right, which is conducive to aligning with the unlocking position and quickly unlocking.
[0020] Preferably, the unlocking rod lifting detection device further includes a fixing component, and the first detection component and the second detection component are both fixedly installed on the fixing component.
[0021] In this solution, the above-mentioned structural form is adopted. The fixing component can achieve the fixed installation of the test piece, which can ensure the installation stability of the test piece and help ensure the detection accuracy of the test piece.
[0022] Preferably, the fixing component includes a mounting body and at least one adjusting body, the first detection element and / or the second detection element are connected to the adjusting body, and the adjusting body is movably connected to the mounting body.
[0023] In this solution, the above-mentioned structural form is adopted. The first detection element, the second detection element, and the third detection element are movably installed on the mounting body through the adjustment body. By using the adjustment body, the installation position of the detection element can be easily adjusted, and the detection element can be disassembled and assembled.
[0024] Preferably, the adjusting body is provided with an adjusting groove, through which the first detection element can be adjusted in the driving direction of the driving mechanism, and through which the second detection element can be adjusted in the unlocking direction of the unlocking rod.
[0025] In this scheme, the above-mentioned structural form is adopted. The adjusting body adjusts the installation position of the detection piece through the adjusting groove, which helps to ensure the detection accuracy of each detection piece. At the same time, the adjustment direction of the adjusting groove corresponding to the first and second detection pieces is related to the movement direction of the corresponding moving parts, so as to facilitate fine adjustment of the detection pieces.
[0026] Preferably, both the first detection element and the second detection element are proximity switches.
[0027] In this solution, the above-mentioned structural form is adopted. The first and third detection elements limit the left and right movement limits of the unlocking guide block to ensure the accurate unlocking operation and protect the unlocking device. By detecting signals simultaneously by the first and second detection elements, it is ensured that the unlocking rod can unlock normally after the drive mechanism moves.
[0028] Preferably, the unlocking lever is a torque unlocking lever, which applies torque to cooperate with the unlocking mechanism to achieve unlocking.
[0029] In this solution, the unlocking lever adopts such a structure and unlocking method, which makes it suitable for various unlocking environments.
[0030] A battery swapping device, characterized in that the battery swapping device includes the unlocking rod lifting detection device described above.
[0031] Preferably, the battery swapping equipment is installed in a battery swapping shuttle, the battery swapping shuttle comprising: a body fixing plate and / or a battery pack fixing plate, the body fixing plate being used to connect and fix to the body of the electric vehicle; the battery pack fixing plate being used to connect and fix to the battery pack, and the unlocking lever lifting detection device being installed on the body fixing plate or the battery pack fixing plate.
[0032] In this solution, the above-mentioned structural form is adopted. The vehicle body fixing plate can prevent relative movement between the vehicle body and the battery swapping shuttle, which is conducive to the battery swapping shuttle smoothly unlocking and unlocking the battery pack; the battery pack fixing plate can prevent relative movement between the battery swapping shuttle and the battery pack, which is conducive to unlocking and unlocking the battery pack.
[0033] Preferably, the battery pack fixing plate is located above the vehicle body fixing plate, the unlocking lever lifting detection device is installed on the vehicle body fixing plate, and the battery pack fixing plate has a clearance groove at one end near the unlocking lever lifting detection device, through which the unlocking lever lifting detection device is fixed to the vehicle body fixing plate.
[0034] In this solution, the above-mentioned structural form is adopted, and the opening of the clearance groove can prevent the upper battery pack fixing plate from obstructing the unlocking rod and avoid interfering with the operation of the unlocking rod.
[0035] Preferably, the unlocking lever lifting detection device is mounted on the battery swapping shuttle or the battery pack.
[0036] In this solution, using the above-mentioned structure, the unlocking lever can be set on the battery swapping vehicle to push the locking lever of the battery pack, or it can be set on the battery pack to directly unlock the locking mechanism at the vehicle end.
[0037] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.
[0038] The positive and progressive effects of this invention are as follows:
[0039] In this invention, a drive mechanism drives an unlocking lever to unlock the battery pack. A first detection element detects the drive mechanism to ensure it is driven into position. A second detection element detects the unlocking lever to ensure it moves correctly and unlocks after the drive mechanism moves. The battery pack can only be unlocked when the unlocking lever reaches a second set position. The second detection element detects whether the unlocking lever has reached the set position to ensure normal unlocking operation. Signals can be detected simultaneously by the first and second detection elements to ensure the unlocking lever unlocks correctly after the drive mechanism moves. Simultaneously, the first and third detection elements limit the lateral movement of the unlocking guide block to ensure accurate unlocking and protect the unlocking device.

[0079] The present invention will be described more clearly and completely below by way of embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.
[0080] This invention provides a battery swapping device 8, which is installed on a battery swapping shuttle 9 to replace the battery pack in an electric vehicle. The battery swapping device 8 is equipped with an unlocking lever lifting detection device 01, capable of unlocking the battery pack in the electric vehicle. Figure 1-9 As shown, the unlocking lever lifting detection device 01 includes an unlocking lever 1 and a drive mechanism 2. The drive mechanism 2 is used to drive the unlocking lever 1 to move so that the unlocking lever 1 can unlock the locking mechanism 40 on the electric vehicle.
[0081] like Figure 1-9 As shown, the unlocking lever 1 is vertically set. Under the driving action of the driving mechanism 2, the unlocking lever 1 can move up and down along its axis and act on the locking mechanism 40 on the electric vehicle to unlock the locking mechanism 40, thereby realizing the separation or connection of the battery pack from the body of the electric vehicle.
[0082] Meanwhile, the unlocking lever lifting detection device 01 also includes a first detection element 3, which is used to detect whether the drive mechanism 2 has moved to the first set position; and a second detection element 4, which is used to detect whether the unlocking lever 1 has been driven upward by the drive mechanism 2 to the second set position.
[0083] In this embodiment, a first detection element 3 is provided at a first set position on one side of the drive mechanism 2. When the first detection element 3 detects that the drive mechanism 2 has moved to the first set position, the first detection element 3 can generate a first electrical signal. A second detection element 4 is provided at a second set position on one side of the unlocking rod 1. When the second detection element 4 detects that the unlocking rod 1 has moved to the second set position, the second detection element 4 can generate a second electrical signal. The unlocking rod lifting detection device 01 can receive the first electrical signal and the second electrical signal and determine whether the drive mechanism 2 and the unlocking rod 1 have moved to the correct position respectively.
[0084] In this invention, the driving mechanism 2 drives the unlocking lever 1 to move and unlock the battery pack. The first detection element 3 detects the driving mechanism 2 to ensure that the driving structure can be driven into place. The second detection element 4 detects the unlocking lever 1 to ensure that the unlocking lever 1 can move normally and unlock after the driving mechanism 2 moves. The battery pack can only be unlocked when the unlocking lever 1 moves to the second set position. The second detection element 4 detects whether the unlocking lever 1 has moved to the set position to ensure that the unlocking work is carried out normally.
[0085] like Figure 1-9 As shown, the drive mechanism 2 is used for horizontal driving to move the unlocking rod 1 up and down. In this embodiment, the drive mechanism 2 is horizontally positioned, and the unlocking rod 1 is vertically positioned. When the battery swapping shuttle 9 enters the underside of the electric vehicle, the drive mechanism 2 moves horizontally and drives the unlocking rod 1 upward, thereby unlocking the locking mechanism 40 on the electric vehicle and separating the battery pack from the vehicle body. In this invention, the up and down movement of the unlocking rod 1 can be accomplished by the horizontal movement of the drive mechanism 2, which helps to lower the height of the unlocking rod lifting detection device 01, making it easier to enter the underside of electric vehicles with different chassis heights.
[0086] Among them, such as Figure 1-9 As shown, the drive mechanism 2 includes an unlocking guide block 21 and a driver 22. The driver 22 is fixedly connected to the unlocking guide block 21. The driver 22 is used to drive the unlocking guide block 21 to move in a direction away from the driver 22 to a first set position, so as to drive the unlocking rod 1 to move upward.
[0087] In this embodiment, the unlocking guide block 21 and the driver 22 are horizontally arranged. An unlocking rod 1 is vertically installed within the unlocking guide block 21. When the driver 22 drives the unlocking guide block 21 to move horizontally away from the driver 22 to a first set position, the unlocking guide block 21 drives the unlocking rod 1 upwards to a second set position, thereby unlocking the locking mechanism 40 on the electric vehicle. The drive mechanism 2 adopts a split design, with the driver 22 driving the unlocking rod 1 through the unlocking guide block 21. This split design reduces the precision requirements for the installation position between the drive mechanism 2 and the unlocking rod 1, thus reducing production costs.
[0088] In addition, the unlocking lever lifting detection device 01 also includes a third detection element 5, which is used to detect that the unlocking guide block 21 moves to a third set position in the direction close to the driver 22.
[0089] A third setting position is provided on the side of the unlocking guide block 21 near the driver 22. A third detection element 5 is installed at the third setting position. When the driver 22 drives the unlocking guide block 21 to move back, the third detection element 5 is set between the unlocking guide block 21 and the driver 22 to determine the movement position of the unlocking guide block 21. The third detection element 5 helps to ensure that the stroke of the unlocking guide block 21 moving back is not excessive, and helps to protect the structure of the unlocking rod lifting detection device 01 and extend its service life.
[0090] like Figure 6 and Figure 8 As shown, the unlocking guide block 21 is provided with an unlocking guide groove 211, which includes a first guide portion 212 and a second guide portion 213. The first setting position is the position of the unlocking guide block 21 when the unlocking rod 1 is driven to the end of the first guide portion 212 away from the second guide portion 213. The second setting position is the position of the side detection position of the unlocking rod 1 when the unlocking rod 1 rises to a set height, and the set height is less than or equal to the maximum stroke height of the unlocking rod 1. The third setting position is the position of the unlocking guide block 21 when the unlocking rod 1 is driven to the end of the second guide portion 213 away from the second guide portion 213.
[0091] The unlocking guide groove 211 includes a first guide portion 212, a second guide portion 213, and a third guide portion. The extension direction of the first guide portion 212 is the same as the movement direction of the unlocking guide block 21; the second guide portion 213 is parallel to the first guide portion 212 and located at the lower end of the first guide portion 212; one end of the third guide portion is inclined downward from the end of the first guide groove near the third guide portion, and the other end of the third guide portion is connected to the end of the second guide portion 213 near the third guide portion.
[0092] In this embodiment, the unlocking guide groove 211 includes a first guide portion 212 that moves in the same direction as the unlocking guide block 21 and a second guide portion 213 that is parallel to the first guide portion 212 and located at the lower end of the first guide portion 212. The first guide portion 212 and the second guide portion 213 ensure that the unlocking guide block 21 can move horizontally and provide horizontal support for the stopping of the protrusion of the unlocking rod 1. It also includes a third guide portion that is inclined downward from the first guide portion 212 and connects to the second guide portion 213, ensuring that the protrusion of the locking rod can move up and down.
[0093] like Figure 2-5 As shown, the unlocking rod lifting detection device 01 also includes a horizontal guide mechanism 6. The horizontal guide mechanism 6 has a horizontal guide groove 61. The unlocking rod 1 is installed with left and right limits relative to the horizontal guide groove 61. The fixing component 7 is fixedly installed on the horizontal guide mechanism 6. The horizontal movement of the unlocking guide block 21 in the horizontal guide groove 61 causes the unlocking rod 1 to move up and down relative to the horizontal guide mechanism 6 along the unlocking guide block 21.
[0094] In this embodiment, the horizontal guiding mechanism 6 includes a horizontal guide frame with a horizontal guide groove 61 inside. The horizontal guide groove 61 guides the horizontal movement of the unlocking guide block 21. The unlocking guide block 21 has a slot at one end near the drive mechanism 2. The drive mechanism 2 includes a thrust output end and a connecting block fixed to the thrust output end, the connecting block being embedded in the slot. In this invention, the horizontal guiding mechanism 6 guides and constrains the horizontal movement of the unlocking guide block 21, thereby ensuring stable up-and-down movement of the unlocking rod 1 along the unlocking guide groove 211 to achieve unlocking, thus saving space in the vertical direction.
[0095] Among them, such as Figure 2-5 As shown, the unlocking rod lifting detection device 01 also includes a vertical guide groove 62 fixedly installed on the horizontal guide mechanism 6, through which the unlocking rod 1 can move up and down.
[0096] In this embodiment, a vertical guide mechanism is provided to guide the unlocking rod 1, thereby ensuring that the unlocking rod 1 moves up and down in a predetermined direction and avoids tilting to the left or right, which is conducive to aligning with the unlocking position and quickly unlocking.
[0097] In addition, the unlocking lever lifting detection device 01 also includes a fixing component 7, such as Figure 1-9 As shown, the first detection component 3 and the second detection component 4 are both fixedly installed on the fixed component 7.
[0098] In this embodiment, the first detection element 3, the second detection element 4, and the third detection element 5 are fixedly installed on the fixed component 7 on the side opposite to the unlocking guide block 21. The first detection element 3 is installed on the fixed component 7 on the side away from the driver 22. The second detection element 4 is installed on the fixed component 7 at the position corresponding to the unlocking lever 1, and the third detection element 5 is installed on the fixed component 7 on the side close to the driver 22. The fixed component 7 can achieve the fixed installation of the detection elements, ensuring the installation stability of the detection elements and facilitating the guarantee of the detection accuracy of the detection elements.
[0099] The fixing component 7 includes a mounting body 71 and at least one adjusting body 72. The first detection element 3 and / or the second detection element 4 are connected to the adjusting body 72, and the adjusting body 72 is movably connected to the mounting body 71.
[0100] like Figure 2-5 As shown, the fixing component 7 adopts a split design. The fixing component 7 includes a plate-shaped mounting body 71 that is vertically fixed parallel to the unlocking guide block 21. The first detection component 3, the second detection component 4 and the third detection component 5 are respectively movably mounted on the mounting body 71 through the adjusting body 72. By using the adjusting body 72, the installation position of the detection component can be easily adjusted, and the detection component can be easily disassembled and assembled.
[0101] Meanwhile, the adjusting body 72 is provided with an adjusting groove 721. The first detection element 3 can adjust its installation position along the driving direction of the driving mechanism 2 through the adjusting groove 721, and the second detection element 4 can adjust its installation position along the unlocking direction of the unlocking rod 1 through the adjusting groove 721.
[0102] like Figure 2-5 As shown, the adjusting body 72 is provided with an adjusting groove 721, which is an oblong hole. A screw passes through this oblong hole to connect the adjusting body 72 to the mounting body 71. Simultaneously, the oblong hole on the adjusting body 72 at the first detection element 3 is horizontally oriented to facilitate horizontal position adjustment of the first detection element 3. The oblong hole on the adjusting body 72 at the second detection element 4 is vertically oriented to facilitate vertical position adjustment of the second detection element 4. The adjusting body 72 adjusts the installation position of the detection elements through the adjusting groove 721, which helps ensure the detection accuracy of each detection element. Furthermore, the adjustment direction of the first detection element 3 and the second detection element 4 corresponding to the adjusting groove 721 is related to the movement direction of the corresponding moving parts, facilitating fine-tuning of the detection elements.
[0103] In this embodiment, the first detection element 3, the second detection element 4, and the third detection element 5 are all proximity switches. When the first detection element 3 detects that the unlocking guide block 21 has moved to a first set position away from the driver 22, the first detection element 3 can send a first electrical signal to determine that the driver 22 has driven the unlocking guide block 21 into position. When the second detection element 4 detects that the unlocking rod 1 has moved upward to a second set position, the second detection element 4 can send a second electrical signal to determine that the unlocking rod 1 has reached the required height. When the third detection element 5 detects that the unlocking guide block 21 has moved to a third set position close to the driver 22, the third detection element 5 can send a third electrical signal to determine that the unlocking guide block 21 has retracted into position. The first detection element 3 and the third detection element 5 limit the left and right movement limits of the unlocking guide block 21 to ensure the accurate unlocking operation and protect the unlocking device.
[0104] In another embodiment, the unlocking lever 1 is a torque unlocking lever, which applies torque to cooperate with the unlocking mechanism to achieve unlocking.
[0105] In this case, the unlocking rod 1 can be a torque gun. When the unlocking mechanism is a threaded lock, an external thread is provided on the outer circumference of the unlocking rod 1. When unlocking is required, the unlocking rod 1 drives the external thread to move to unlock with the internal thread on the unlocking mechanism. When the unlocking mechanism is a T-lock, a transverse rod is provided at the top of the unlocking rod 1. The transverse rod is fixedly connected to the rod body of the unlocking rod 1, forming a T-shaped structure. The rotation of the unlocking rod 1 causes the transverse rod to change angle. When the angle of the transverse rod is consistent with the opening angle on the T-lock, the transverse rod disengages from the opening on the T-lock to unlock with the unlocking mechanism. Using this structure and unlocking method with the unlocking rod 1 makes it suitable for various unlocking environments. In addition, the battery swapping shuttle 9 may also include: a body fixing plate 81 and / or a battery pack fixing plate 82, such as... Figure 1-2 As shown, the battery pack fixing plate 82 is used to hold and fix the battery pack, the body fixing plate 81 is used to connect and fix the electric vehicle to the body of the electric vehicle when swapping batteries, and the unlocking rod lifting detection device 01 is installed on the body fixing plate 81 or the battery pack fixing plate 82.
[0106] In one embodiment, such as Figure 1-2 The battery swapping shuttle 9 and its battery swapping equipment 8 include a vehicle body fixing plate 81 and a battery pack fixing plate 82. The battery pack fixing plate 82 is used to connect and position the battery pack. The battery pack fixing plate 82 is located above the vehicle body fixing plate 81. The vehicle body fixing plate 81 can prevent relative movement between the vehicle body and the battery swapping shuttle 9, thereby facilitating the battery swapping shuttle 9 to smoothly unlock and unlock the battery pack. The battery pack fixing plate 82 can drive the battery pack to move relative to the battery swapping shuttle 9 in the unlocking and unlocking direction, thereby facilitating the unlocking and unlocking of the battery pack.
[0107] like Figure 2-5 As shown, the battery pack fixing plate 82 is provided with a battery tray and a battery positioning component, and can be driven by the drive mechanism 2 and guided by the guide rail to move in the unlocking direction. The vehicle body fixing plate 81 is provided with a vehicle body positioning component, and can be driven by the drive mechanism 2 and guided by the guide rail to move in the unlocking direction.
[0108] The battery pack fixing plate 82 is located above the body fixing plate 81, the unlocking rod lifting detection device 01 is installed on the body fixing plate 81, and a clearance groove is provided at one end of the battery pack fixing plate 82 near the unlocking rod lifting detection device 01. The unlocking rod lifting detection device 01 passes through the clearance groove and is fixed to the body fixing plate 81.
[0109] The battery pack mounting plate 82 has a clearance groove, through which the unlocking lever 1 passes and is fixed to the vehicle body mounting plate 81. The clearance groove prevents the upper battery pack mounting plate 82 from obstructing the unlocking lever 1 and avoids interfering with its operation.
[0110] Meanwhile, a tray is also installed on the battery pack fixing plate 82. The tray has a waist-shaped hole. The unlocking rod 1 passes through the waist-shaped hole through the tray to unlock the locking mechanism 40 above it.
[0111] In this embodiment, as Figure 9-12 The unlocking lever 1 and the unlocking lever lifting detection device 01 can be installed on the battery swapping shuttle. The unlocking lever 1 is used to push the inner top rod 50 of the battery pack, and the unlocking lever lifting detection device 01 detects the lifting of the unlocking lever 1 and the movement position of the drive mechanism 2.
[0112] like Figure 10-12 As shown, body brackets are simultaneously connected to the two longitudinal beams of the electric vehicle. The body brackets are frame structures welded from profiles. Each locking mechanism 40 is located on the lower surface of the longitudinal beams of the body bracket and is used to lock with the locking engagement mechanism 3 on the battery pack, allowing the battery pack to connect or disconnect relative to the body bracket, thus facilitating battery replacement. The locking mechanisms 40 are arranged in two rows on the lower surface of the body bracket, corresponding to the two longitudinal beams respectively. Figure 10 As shown, the connectors at each mounting bracket 50 on the battery pack for electric vehicles are used to pass through the locking mechanism 40 to achieve locking.
[0113] During the unlocking process, the vehicle body fixing plate 81 and the battery pack fixing plate 82 move in the first direction, so that the vehicle body positioning component and the battery pack fixing plate 82 are adjusted to a suitable position according to the position of the vehicle body positioning hole and the position of the battery pack of the vehicle to be replaced. The vehicle body fixing plate 81 is lifted and positioned with the vehicle body. The battery pack fixing plate 82 is positioned by the positioning component and drives the battery pack to move. Since the battery pack fixing plate 82 can move, and the unlocking rod 1 is located on the battery pack fixing plate 82, the sliding hole of the battery pack is set as an oblong sliding hole, or a sliding hole with a diameter relatively larger than the movement stroke of the battery pack fixing plate 82 during the unlocking process.
[0114] When locking: The unlocking rod 1 can be raised to unlock or lock the battery pack. The unlocking rod 1 rises into the sliding hole of the battery pack and pushes the top rod inside the battery pack, which in turn pushes the locking mechanism 40 to open the lock. The mounting bracket 50 on the battery pack is then pushed into the L-shaped groove of the locking mechanism 40 to lock the battery pack.
[0115] During unlocking: the battery pack fixing plate 82 moves the battery pack towards the inside of the L-shaped groove of the locking mechanism 40, the unlocking rod 1 pushes the locking rod, and the locking rod pushes the locking mechanism 40, the locking mechanism 40 opens, the battery pack fixing plate 82 moves the hook at the battery pack mounting bracket 50 towards the unlocking port of the L-shaped groove, and exits the locking mechanism 40, thus unlocking.
[0116] Specifically, such as Figure 10-12The unlocking rod 1 pushes the top rod mechanism 400, and the lifting seat 41 of the unlocking rod 1 drives the top rod to push upward, lifting the locking rod of the locking mechanism 40 to unlock. Then, the hanging part at the mounting bracket 50 is pushed into the L-shaped groove, and the locking rod of the locking mechanism 40 falls down to lock.
[0117] In another embodiment, the unlocking lever 1 can also be set on the battery pack to directly unlock the locking mechanism 40 at the vehicle end. The unlocking lever lifting detection device 01 can be set on the battery pack to directly detect the lifting status of the unlocking lever 1.
[0118] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
