[0037]

[0003] With the development of new energy technologies, the number of devices that use batteries is increasing. When an electric power consuming device runs out of electrical energy, it is generally replenished with electrical energy by connecting to a charging device, for example, an electric vehicle can be charged by connecting to a charging station. Compared to the method of replenishing electrical energy by connecting to a charging station or other charging device, battery replacement can achieve electrical energy replenishment more quickly, and there are currently battery replacement systems dedicated to battery replacement, which are equipped with a battery insertion / removal device and a portable battery replacement device, and the battery replacement device is used to replace the batteries of the electric power consuming device.

[0038] The current battery exchange device includes a floating platform, a locking / unlocking mechanism, and a positioning mechanism. The locking / unlocking mechanism is installed on the floating platform and is used to lock or unlock the battery to or from the power consumption device. The positioning member is installed on the floating platform and is positioned to fit with the power consumption device to realize the positioning between the floating platform and the power consumption device.

[0039] The inventors noticed that the positioning member is fixed to the positioning platform. The positioning member limits the maximum height of the battery exchange device, making the battery exchange device taller and occupying a large amount of space. Furthermore, the positioning pin is fixed to the positioning platform, so the power consumption device must be adjusted to the height of the positioning pin. However, power consumption devices are generally large in volume, making it difficult to adjust the power consumption device to the height of the positioning pin, resulting in low battery replacement efficiency.

[0040] It is necessary to solve the problems of the large vertical space occupied by the battery replacement device and the low efficiency of battery replacement due to the need to align the height of the power consumption device with the positioning member. To this end, the present application provides the following technical solution: To adjust the height of the positioning member, a driving member drives the positioning member to move along the vertical direction of the battery replacement device; when the battery replacement device is transporting a battery or is not operating, the driving member drives the positioning member to move downward to lower the height of the positioning member, thereby reducing the height of the battery replacement device and the vertical space occupied by the battery replacement device. When the battery replacement device transports a battery, reducing the height of the battery replacement device improves the ease of passage of the battery replacement device and reduces the height required to lift the power consumption device. When the battery replacement device replaces a battery in the power consumption device, the driving member drives the positioning member to move upward to raise the height of the positioning member, thereby positioning and fitting the positioning member to the power consumption device, making it easier to position and fit the positioning member to the power consumption device. The positioning member is moved to achieve positioning and fitting with the power consumption device, which is simple and efficient to operate, and the positioning member can be adjusted to different height positions to fit power consumption devices of different heights.

[0041] The battery exchange device and battery exchange system disclosed in the embodiments of the present application may be used to exchange batteries in vehicles, but are not limited to this, and may also be used to exchange batteries in other power-consuming devices such as ships, aircraft, etc., such as electric toys, electric tools, battery cars, electric vehicles, ships, spacecraft, etc. The electric toys may include, for example, game consoles, electric car toys, electric boat toys, electric plane toys, etc., which may be stationary or movable. The electric tools may include, for example, electric machine tools, electric cleaning vehicles, etc., which may be stationary or movable. The spacecraft may include, for example, aircraft, rockets, space shuttles, spaceships, etc.

[0042] The battery exchange device and the battery exchange system will be described below using an example in which the power consuming device is a vehicle.

[0043] Referring to FIGS. 1 and 2, a battery exchange system 1000 includes a battery exchange device 100 and a battery insertion / removal device 200.

[0044] The battery exchange system 1000 further includes a battery charging device (not shown) used to store and charge the battery 2000. The battery loading / unloading device 200 may be a stacker, and is provided with forks 210 (the forks 210 may be replaced by robotic arms), which are used to remove the battery 2000 to be charged from the battery exchange device 100 and place it in the battery charging device for recovery, and also remove the fully charged battery 2000 from the battery charging device and place it on the battery exchange device 100.

[0045] To replace the vehicle battery 2000, it is necessary to remove the battery 2000 from the vehicle that has run out of electrical energy via the battery exchange device 100, transport it to the battery charging / discharging device base for charging, and then transport the fully charged battery 2000 to the vehicle via the battery exchange device 100 and install the battery 2000 in the vehicle. In some embodiments, the battery exchange system 1000 further includes a rail 300, and the battery exchange device 100 is movably installed on the rail 300.

[0046] The battery exchange device 100 moves back and forth on the rails 300, thereby moving between the vehicle and the battery loading / unloading device 200, and the battery exchange device 100 removes the battery 2000 to be charged from the vehicle and transports it along the rails 300 to the battery loading / unloading device 200, and installs a new, fully charged battery 2000 in the vehicle by the battery loading / unloading device 200.

[0047] The battery exchange system 1000 further includes a battery exchange platform 400 located at one end of the rail 300, and the battery access device 200 located at the other end of the rail 300. The battery exchange platform 400 is used to park a vehicle, and the vehicle exchanges a battery 2000 on the battery exchange platform 400. The battery exchange platform 400 is used to lift the entire vehicle, and the vehicle is positioned above the battery exchange platform 400. A relief opening 410 is formed in the battery exchange platform 400, and the installation position (not shown) of the vehicle's battery 2000 corresponds to the relief opening 410. The battery exchange device 100 stops below the relief opening 410, and the battery exchange mechanism on the battery exchange device 100 passes through the relief opening 410 to remove or install the battery 2000. The battery exchange device 100 moves between the battery exchange platform 400 and the battery access device 200.

[0048] The mounting position of the battery 2000 refers to a space formed in the power consumption device for accommodating the battery 2000, such as an upwardly recessed groove formed in the chassis of a vehicle, such that when the battery 2000 is positioned within the groove, the surface of the battery 2000 is approximately flush with the rest of the chassis.

[0049] Referring to FIG. 2, in some embodiments, the battery exchange device 100 includes a floating platform 10, a locking / unlocking mechanism 20, and a positioning mechanism 30, where the locking / unlocking mechanism 20 is installed on the floating platform 10 and is used to lock or unlock the battery 2000 to or from the power consumption device, the positioning mechanism 30 is installed on the floating platform 10 and is used to realize positioning between the floating platform 10 and the power consumption device, and the positioning mechanism 30 includes a positioning member 32 and a driving member 31, where the driving member 31 is arranged to drive the positioning member 32 to move along the height direction of the battery exchange device 100 to adjust the height of the positioning member 32.

[0050] Depending on the connection relationship between the battery 2000 and the power consumption device, the lock / unlock mechanism 20 may be configured in a correspondingly different manner. For example, in some embodiments, a tightening bolt is provided on the battery 2000, a movable nut is provided on the vehicle chassis, the tightening bolt is threaded onto the movable nut, the lock / unlock mechanism 20 is used to screw the tightening bolt into the movable nut to fix and attach the battery 2000 to its attachment position, and the lock / unlock mechanism is used to remove the tightening bolt from the movable nut to unlock the battery 2000 from the vehicle. For example, the lock / unlock mechanism 20 includes a lock / unlock drive motor 21 and a bolt sleeve 22, one end of the bolt sleeve 22 is connected to the output end of the lock / unlock drive motor 21, the other end of the bolt sleeve 22 is fitted onto the tightening bolt, and the lock / unlock drive motor 21 drives the bolt sleeve 22 to rotate forward or backward, thereby moving the tightening bolt to screw into or remove from the movable nut. In other embodiments, the locking / unlocking mechanism 20 may employ other methods of locking and unlocking the battery 2000.

[0051] Since the floating platform 10 can float relative to the power consumption device, the positioning mechanism 30 fixes the floating platform 10 and the power consumption device, making it easier for the locking / unlocking mechanism 20 to lock or unlock the battery 2000 to or from the power consumption device, thereby improving the success rate of attaching and detaching the battery 2000.

[0052] The height direction of the battery exchange device 100 is perpendicular to the plane on which the floating platform 10 is located.

[0053] The driving member 31 may be a motor, an air cylinder, a hydraulic cylinder, etc. The driving member 31 may directly drive the positioning member 32 to move it along the height direction of the battery exchange device 100, or may indirectly drive the positioning member 32 to move it along the height direction of the battery exchange device 100.

[0054] The number of positioning mechanisms 30 may be one or more, and may be reasonably set based on the positioning mechanisms 30 required for actual applications. In an embodiment with multiple positioning mechanisms 30, the multiple positioning mechanisms 30 may jointly position the floating platform 10 and the power consuming device, or some of the positioning mechanisms 30 may position the floating platform 10 and the power consuming device. "Multiple" means two or more.

[0055] The driving member 31 can drive the positioning member 32 to move along the height direction of the battery exchange apparatus 100 to adjust the height of the positioning member 32. When the battery exchange apparatus 100 is transporting a battery 2000 or is not operating, the driving member 31 drives the positioning member 32 to move downward to lower the height of the positioning member 32, thereby reducing the height dimension of the battery exchange apparatus 100 and the space dimension occupied by the battery exchange apparatus 100 in the height direction. By reducing the height dimension of the battery exchange apparatus 100 while the battery exchange apparatus 100 is transporting a battery 2000, the battery exchange apparatus 100 can be made easier to pass through and the lifting height of power consumption devices can be reduced. When the battery exchange device 100 is replacing the battery 2000 of the power consumption device, the positioning member 32 is moved upward by the driving member 31 to raise the height of the positioning member 32, thereby positioning the positioning member 32 and the power consumption device, thereby positioning the floating platform 10 and the power consumption device and facilitating the positioning and fitting of the positioning member 32 with the power consumption device. The positioning and fitting of the power consumption device is achieved by moving the positioning member 32, which is simple and efficient to operate, and the positioning member 32 can be adjusted to different heights to suit power consumption devices of different heights.

[0056] As shown in Figures 3 and 4, in some embodiments, the positioning mechanism 30 includes a transmission assembly 33, the drive member 31 and the positioning member 32 are operably connected via the transmission assembly 33, and the transmission assembly 33 is arranged to convert rotation of the output end of the drive member 31 into linear movement of the positioning member 32.

[0057] The driving member 31 may be directly connected to the positioning member 32 to directly drive and move the positioning member 32, or may be indirectly connected thereto. The driving member 31 is operatively connected to the positioning member 32 via a transmission assembly 33, i.e., the driving member 31 indirectly drives the positioning member 32 to move along the height direction of the battery exchange device 100 via the transmission assembly 33.

[0058] The transmission assembly 33 can convert the rotation of the output end of the drive member 31 into linear movement of the positioning member 32, thereby reducing the height dimension of the positioning mechanism 30 and the space occupied by the positioning mechanism 30 in the height direction.

[0059] The rotation of the output end of the driving member 31 is converted into the linear movement of the positioning member 32. The transmission assembly 33 may have various structural forms. For example, as shown in Figures 3 and 4, in some embodiments, the transmission assembly 33 includes a first gear 331, a second gear 332, and a lead screw 333, where the first gear 331 meshes with the second gear 332 and is connected to the output end of the driving member 31, the second gear 332 is fitted onto and threadedly engages with the lead screw 333, and the positioning member 32 is connected to the lead screw 333, and the rotation axis of the first gear 331, the rotation axis of the second gear 332, and the axis of the lead screw 333 all coincide with the height direction of the battery exchange device 100.

[0060] The driving member 31 is a motor, and the output shaft of the driving member 31 rotates to drive and rotate the first gear 331, and the second gear is rotatably connected to the floating platform 10, and the first gear 331 rotates to drive and rotate the second gear 332, which has a threaded hole into which a lead screw 333 is threaded. The first gear 331 drives the second gear 332 to rotate around the axis of the lead screw 333, and the second gear 332 threads into the lead screw 333, and the rotation of the second gear 332 drives the lead screw 333 to move along the height direction of the battery exchange apparatus 100, thereby moving the positioning member 32 to move along the height direction of the battery exchange apparatus 100.

[0061] In other embodiments, the transmission assembly 33 may be of other structural types, such as a belt transmission assembly 33 or a chain transmission assembly 33. For example, the transmission assembly 33 is a driven assembly 33, which includes a driving wheel, a driven wheel, a transmission belt, and a lead screw 333. The driving wheel is connected to the output end of the driving member 31, the driven wheel is fitted onto the lead screw 333 and is screwed onto the lead screw 333, the output shaft of the driving member 31 rotates to drive the rotation of the driving wheel, the driving wheel drives the rotation of the driven wheel via the transmission belt, and the rotation of the driven wheel drives the lead screw 333 to move linearly along the height direction of the battery exchange device 100, thereby moving the positioning member 32 to move along the height direction of the battery exchange device 100.

[0062] The first gear 331 meshes with the second gear 332, which is fitted onto and threadedly engages with the lead screw 333, and the rotation axes of the first gear 331, the second gear 332, and the lead screw 333 all coincide with the height direction of the battery exchange device 100. Therefore, the first gear 331, the second gear 332, and the lead screw 333 work together to convert the rotation of the output end of the driving member 31 into the linear movement of the positioning member 32. The transmission assembly 33 is operatively connected between the driving member 31 and the positioning member 32, thereby reducing the height dimension of the positioning mechanism 30 and the space it occupies in the height direction.

[0063] As shown in FIGS. 4 and 5 , in some embodiments, the positioning mechanism 30 further includes a first mounting seat 34, a connecting plate 35, and a first guide shaft 36, where the mounting seat is fixed to the floating platform 10, the driving member 31, the first gear 331, and the second gear 332 are all mounted on the mounting seat, the connecting plate 35 is connected to the lead screw 333, the positioning member 32 is connected to the connecting plate 35, and the first guide shaft 36 is slidable on the first mounting seat 34. Insertion and connected to the connecting plate 35.

[0064] The driving member 31, the first gear 331, and the second gear 332 are all mounted on mounting seats, i.e., the driving member 31, the first gear 331, and the second gear 332 are all indirectly mounted to the floating platform 10 via the mounting seats. In other embodiments, the driving member 31, the first gear 331, and the second gear 332 may be directly fixed to the floating platform 10.

[0065] The first mounting seat 34 is provided with a first guide hole 341, and the first guide shaft 36 is inserted into the first guide hole 341. The number of first guide shafts 36 and first guide holes 341 may be plural, and the first guide shafts 36 and first guide holes 341 may be arranged in a one-to-one correspondence. The first guide holes 341 are inserted into the corresponding first guide holes 341, so that when the driving member 31 drives the positioning member 32 to move along the height direction of the battery exchange device 100, the first guide shaft 36 slides in the axial direction of the corresponding first guide hole 341. In other embodiments, the first guide hole 341 may be installed on the connecting plate 35, and the first guide member may be installed on the mounting base. In embodiments in which the driving member 31, the first gear 331, and the second gear 332 are all directly fixed to the floating platform 10, the first guide hole 341 may be installed on the floating platform 10.

[0066] The first guide shaft 36 is connected to the connecting plate 35, and the first guide shaft 36 is slidably mounted on the first mounting seat 34. Insertion This can serve as a guide when the positioning member 32 moves along the height direction of the battery exchange device 100, improving the stability of the movement of the positioning member 32 and thereby improving the accuracy of the positioning and fitting of the positioning member 32 to the power consumption device.

[0067] In some embodiments, the positioning mechanism 30 further includes a first detection unit 37 (shown in FIG. 4) used to detect height information of the positioning member 32 .

[0068] The first detection unit 37 is attached to the first mounting seat 34 and is located below the connecting plate 35. The first detection unit 37 detects the height of the connecting plate 35, thereby indirectly detecting the height of the positioning member 32. The first detection unit 37 may be a distance sensor, a proximity switch, a trigger switch, or the like.

[0069] The height information of the positioning member 32 is detected via the first detection unit 37, which can provide a reference for determining whether the positioning member 32 is positioned and mated with the power consumption device, thereby ensuring that the positioning member 32 is positioned and mated with the power consumption device. By detecting the height information of the positioning member 32 with the first detection unit 37, it is possible to avoid insufficient or excessive height adjustment of the positioning member 32.

[0070] As shown in Figures 6 and 7, in some embodiments, the battery exchange device 100 further includes a support mechanism 40 including a second mounting seat 41, a support member 42, and an elastic member 43, wherein the second mounting seat 41 is fixed to the floating platform 10, the elastic member 43 is elastically supported between the support member 42 and the second mounting seat 41, and the support member 42 is arranged to support the battery 2000.

[0071] The fact that the elastic member 43 is resiliently supported between the support member 42 and the second mounting seat 41 can be understood as meaning that the elastic member 43 is indirectly connected to the floating platform 10 via the second mounting seat 41. In other embodiments, the elastic member 43 may be directly connected to the floating platform 10, i.e., the elastic member 43 may be supported between the support member 42 and the floating platform 10.

[0072] The elastic member 43 may be a rubber pad, a spring, etc. Figures 6 and 7 show that the elastic member 43 is a spring, one axial end of which is connected to the support member 42 and the other axial end of which is connected to the second mounting seat 41. Each support mechanism 40 may include one or more elastic members 43.

[0073] The number of support mechanisms 40 may be one or more, and may be reasonably set based on the support mechanisms 40 required for actual applications. In an embodiment where there are multiple support mechanisms 40, the multiple support mechanisms 40 may jointly support the battery 2000, or some of the multiple support mechanisms 40 may support the battery 2000.

[0074] The elastic member 43 is elastically supported between the support member 42 and the second mounting seat 41, and the support member 42 is used to support the battery 2000. When there is a certain amount of tilt in the power consumption device or the battery 2000, the support mechanism 40 will conform to the tilt of the power consumption device or the battery 2000 by compressing the elastic member 43, thereby maintaining close contact between the battery 2000 and the power consumption device, thereby improving the success rate of installing or removing the battery 2000.

[0075] Referring to FIG. 7, in some embodiments, the support mechanism 40 further includes a second guide shaft 44, which is slidably mounted on the second mounting seat 41. Insertion and connected to the support member 42.

[0076] The second mounting seat 41 is provided with a second guide hole 411, and the second guide shaft 44 is inserted into the second guide hole 411. There may be a plurality of second guide shafts 44 and second guide holes 411, or the second guide shafts 44 and second guide holes 411 may be provided in a one-to-one correspondence, and the second guide holes 411 are inserted into the corresponding second guide holes 411, so that when the elastic member 43 is compressed or expanded, the second guide shaft 44 slides in the axial direction of the corresponding second guide hole 411. In an embodiment in which the elastic member 43 is directly connected to the floating platform 10, the second guide hole 411 may be provided on the floating platform 10.

[0077] The second guide shaft 44 is connected to the support member 42, and the second guide shaft 44 is slidably mounted on the second mounting seat 41. Insertion This can play a role in guiding the elastic member 43 during the process of compression or extension, ensuring that the elastic member 43 is compressed or extended along a certain path and that the support member 42 moves along a certain path, thereby improving the stability of the movement of the support member 42 and thereby improving the stability of the support of the support member 42 to the battery 2000.

[0078] Continuing to refer to FIG. 7, in some embodiments, the support mechanism 40 further includes a second detection unit 45 used to detect whether the support member 42 is in contact with the battery 2000.

[0079] The second detection member is attached to the support member 42, and the position of the surface of the support member 42 that comes into contact with the battery 2000 is higher than one end face of the second detection member that is close to the battery 2000, and the height difference between the one end face of the second detection member that is close to the battery 2000 and the surface of the support member 42 that comes into contact with the battery 2000 is constant. The first detection unit 37 may be a distance sensor, a proximity switch, a trigger switch, or the like.

[0080] In an embodiment with a plurality of support mechanisms 40, the number of second detection units 45 is also multiple. For example, the floating platform 10 typically includes three or more second detection units 45, which can detect whether a battery 2000 is present on the support member 42. When the locking / unlocking mechanism 20 completes the installation or removal of the battery 2000 and descends, if the signals from the plurality of second detection units 45 do not match, this indicates that the battery 2000 is not fully locked or unlocked and has tilted. In this case, the floating platform 10 of the battery exchange apparatus 100 stops descending and attempts to lock or unlock again, or issues a fault alarm. The second detection units 45 can prevent the battery 2000 from falling when the floating platform 10 of the battery exchange apparatus 100 descends in a situation where only one side of the battery is locked or unlocked.

[0081] By detecting whether the support member 42 is in contact with the battery 2000 using the second detection unit 45, if the support member 42 is not in contact with the battery 2000 or the contact is incomplete, the support member 42 can be adjusted to make contact with the battery 2000, thereby improving the success rate of unlocking the battery 2000 from the power consumption device.

[0082] Referring to FIG. 8, in some embodiments, the battery exchange device 100 further includes a moving base 50, a lifting platform 60, and a lifting mechanism 70, wherein the floating platform 10 is floatingly connected to the lifting platform 60, and the lifting mechanism 70 is installed between the moving base 50 and the lifting platform 60, and the lifting mechanism 70 is used to lift the lifting platform 60.

[0083] The moving base 50 includes a bottom plate 51, a driving motor 52, and a gear 53. The driving motor 52 is attached to the bottom plate 51, and the gear 53 is attached to the output end of the driving motor 52. The gear 53 engages with a rack (not shown), which may be fixed to the ground or the rail 300. The driving motor 52 drives the gear 53 to rotate, and the gear 53 engages with the rack. During the rotation of the gear 53, the moving base 50 can be driven to move along the extension direction of the rack, thereby moving the battery exchange device 100 along the extension direction of the rack, which is the same as the extension direction of the rail 300.

[0084] In some embodiments, the moving base 50 further includes rollers 54. The rollers 54 engage with the rails 300. The drive motor 52 drives and rotates the gears 53, causing the rollers 54 to roll along the rails 300, thereby moving the battery exchange device 100 along the rails 300. The drive motor 52 may be replaced with a drive motor, a hydraulic drive rod, or the like.

[0085] The floating platform 10 is floatingly connected to the lift platform 60, thereby allowing the floating platform 10 to move in a horizontal plane relative to the lift platform 60 to facilitate positioning engagement of the positioning member 32 with the power consuming device.

[0086] 8 , a plurality of mounting members 11 are installed at intervals below the floating platform 10, each of which includes a first connecting portion 111 and a second connecting portion 112. One end of the first connecting portion 111 is connected to the floating platform 10, and the other end of the first connecting portion 111 extends below the lifting platform 60 and is connected to the second connecting portion 112, whereby the second connecting portion 112 and the first connecting portion 111 form an L-shaped mounting member 11. A plurality of floating chains 61 are connected to the lifting platform 60, the number of which is the same as the number of mounting members 11, and the floating chains 61 are installed in one-to-one correspondence with the mounting members 11. One end of the floating chain 61 is connected to the lifting platform 60, and the other end of the floating chain 61 is connected to the second connecting portion 112 of the corresponding mounting member 11. In the absence of any external force, the length of the floating chain 61 allows the floating platform 10 to float in the air without contacting the lifting platform 60, making it easier for the floating platform 10 to float horizontally relative to the lifting platform 60, and preventing frictional contact between the floating platform 10 and the lifting platform 60 when the floating platform 10 floats horizontally relative to the lifting platform 60, preventing the floating from being hindered.

[0087] The lift mechanism 70 may take a variety of forms, and may be, for example, a power member such as an air or hydraulic cylinder for driving the lift platform 60 to move up and down along the height direction of the battery exchange apparatus 100. Furthermore, as shown in FIGS. 8 and 9 , the lift mechanism 70 is a scissors-type lift mechanism, and the battery exchange apparatus 100 further includes a moving base 50. The lift mechanism 70 is installed between the moving base 50 and the lift platform 60.

[0088] The scissor-type lifting mechanism includes two scissor units 71, a driving member 72, two first transmission members 73, two second transmission members 74, a screw rod 75, and a nut 76. The two scissor units 71 are installed opposite each other and include a first scissor arm 711 and a second scissor arm 712 hinged to each other, one end of the first scissor arm 711 is hingedly connected to the lifting platform 60 and the other end of the first scissor arm 711 is movably mounted on the movable base 50. One end of the second scissor arm 712 is hingedly connected to the movable base 50 and the other end of the second scissor arm 712 is movably mounted on the lifting platform 60. A first slide rail 511 is provided on the bottom plate 51 of the movable base 50, a first slider 7111 is hingedly connected to one end of the first scissor arm 711, and the first slider 7111 is slidably engaged with the first slide rail 511, a second slide rail 62 is provided on the lifting platform 60, and a second slider 7121 is hingedly connected to one end of the second scissor arm 712, and the second slider 7121 is slidably engaged with the second slide rail 62. The second transmission member 74 is engaged with the inclined surface 741 of the first transmission member 73 attached to the mounting shaft 77, and when the second transmission member 74 moves, the first transmission member 73 moves the mounting shaft 77 up and down, the first slider 7111 moves along the first slide rail 511, the second slider 7121 moves along the second slide rail 62, and the first scissor arm 711 and the second scissor arm 712 rotate relative to each other, thereby causing the scissors unit 71 to move up and down vertically.

[0089] The scissors lifting mechanism further includes a mounting shaft 77, which is installed between the two scissors units 71 and is connected to the hinge connection point of the first scissors arm 711 and the second scissors arm 712 and extends along the hinge connection axis of the first scissors arm 711 and the second scissors arm 712. The first transmission member 73 is attached to the mounting shaft 77. The nut 76 is fitted onto the screw rod 75 and threadedly engages with the screw rod 75, and the driving member 72 is used to drive the screw rod 75 to rotate.

[0090] The first transmission member 73 is a roller 54 rotatably mounted on a mounting shaft 77, and the second transmission member 74 has a sloped surface 741 that engages with the roller 54. The second transmission member 74 is fixed to a nut 76.

[0091] When it is necessary to drive the lifting platform 60 to rise, the driving member 72 drives the screw rod 75 to rotate in the forward direction, the nut 76 moves forward along the screw rod 75, and the roller 54 performs an "uphill" motion against the inclined surface 741 of the second transmission member 74, thereby lifting the mounting shaft 77 and causing the scissors unit 71 to move up and down vertically, so that the scissors-type lifting mechanism drives the locking / unlocking mechanism 20 to rise.

[0092] When it is necessary to drive the lifting platform 60 downward, the driving member 72 drives the screw rod 75 to rotate in the reverse direction, the nut 76 moves in the reverse direction along the screw rod 75, and the roller 54 performs a "downhill" motion against the inclined surface 741 of the second transmission member 74, thereby lowering the mounting shaft 77 and causing the scissors unit 71 to move vertically up and down, so that the scissors-type lifting mechanism drives the locking / unlocking mechanism 20 to move downward.

[0093] The lift mechanism 70 is used to raise the lifting platform 60, thereby indirectly lifting the floating platform 10 and the positioning mechanism 30 installed on the floating platform 10, thereby positioning the positioning member 32 of the positioning mechanism 30 to engage with the power consumption device and positioning the floating platform 10 with the power consumption device. The lift mechanism 70 can raise the floating platform 10 and the positioning mechanism 30 installed on the floating platform 10 to different heights to accommodate various power consumption devices. The floating platform 10 is also floatingly connected to the lifting platform 60, which allows the floating platform 10 to float relative to the lifting platform 60. The floating of the floating platform 10 relative to the lifting platform 60 facilitates the positioning of the positioning member 32 of the positioning mechanism 30 with the power consumption device.

[0094] Referring to FIG. 10, in some embodiments, the battery exchange apparatus 100 further includes a locking assembly 80 arranged to lock the floating platform 10 to the lifting platform 60 or release the floating platform 10 from the lifting platform 60.

[0095] The floating platform 10 being locked to the lifting platform 60 means that the floating platform 10 does not move relative to the lifting platform 60, but is not limited to being fixed to the lifting platform 60, and may be suspended in air and stationary relative to the lifting platform 60, i.e., the floating platform 10 and the lifting platform 60 are not in direct contact, but the floating platform 10 does not move relative to the lifting platform 60. The floating platform 10 being released from the lifting platform 60 means that the floating platform 10 can move relative to the lifting platform 60 within a plane parallel to the plane in which the lifting platform 60 is located.

[0096] The lock assembly 80 is arranged to lock the floating platform 10 to the lifting platform 60 or release the floating platform 10 from the lifting platform 60. When it is necessary to position the positioning member 32 of the positioning mechanism 30 with the power consuming device, the lock assembly 80 releases the floating platform 10 from the lifting platform 60, allowing the floating platform 10 to float relative to the lifting platform 60 and facilitating the positioning of the positioning member 32 with the power consuming device. When the lock / unlock mechanism 20 locks or unlocks the battery 2000 to or from the power consuming device, and when the battery exchange device 100 transports the battery 2000, the lock assembly 80 locks the floating platform 10 to the lifting platform 60, thereby stably placing the battery 2000 on the floating platform 10 and improving the stability of the battery 2000 insertion / removal and transportation.

[0097] The lock assembly 80 may have various structural forms. For example, in some embodiments, the lock assembly 80 includes an electromagnet 81 and a magnetic attraction plate 82, where the electromagnet 81 is installed on one of the lifting platform 60 and the floating platform 10, and the magnetic attraction plate 82 is installed on the other of the lifting platform 60 and the floating platform 10.

[0098] 10 , the electromagnet 81 is installed on the lifting platform 60, and the magnetic attraction plate 82 is installed on the floating platform 10. When the electromagnet 81 is energized, a magnetic attraction force is generated that attracts the magnetic attraction plate 82, thereby locking the floating platform 10 to the lifting platform 60. When the electromagnet 81 is de-energized, the magnetic attraction force that attracts the magnetic attraction plate 82 disappears, thereby releasing the floating platform 10 from the lifting platform 60. In another embodiment, the electromagnet 81 may be installed on the floating platform 10, and the magnetic attraction plate 82 may be installed on the lifting platform 60.

[0099] The combination of the electromagnet 81 and the magnetic attraction plate 82 provides a fast response to the operation of locking the floating platform 10 to the lifting platform 60 or releasing the floating platform 10 from the lifting platform 60, and can quickly lock the floating platform 10 to the lifting platform 60 or release the floating platform 10 from the lifting platform 60, thereby improving the replacement efficiency of the battery 2000.

[0100] 11 and 12, in some embodiments, the battery exchange device 100 further includes a protective cover 90, which covers the floating platform 10 and is fixed to a fixing block 12 installed on the floating platform 10. This ensures a clean appearance and prevents the battery exchange device 100 from being soiled by water or dust.

[0101] The protective cover 90 has a first opening 91 for extending the positioning member 32, a second opening 92 for extending the lock / unlock mechanism 20, and a third opening 93 for extending the support member 42. The drive member 31 drives the positioning member 32 to extend from the first opening 91 and align and engage with the power consumption device, thereby positioning the floating platform 10 and the power consumption device, and the lock / unlock mechanism extends from the second opening 92, thereby locking or unlocking the battery 2000 to or from the power consumption device. The support member 42 extends from the third opening 93 to support the battery 2000.

[0102] The opposing outer surface of the protective cover 90 is further provided with a slot 94 for inserting the fork 210 to insert and remove the battery 2000. The protective cover 90 is further provided with a notch 95 for allowing the roller 54 of the moving base 50 to escape.

[0103] An embodiment of the present application provides a battery exchange device 100 including a floating platform 10, a locking / unlocking mechanism 20, a positioning mechanism 30, a support mechanism 40, a moving base 50, a lifting platform 60, a lifting mechanism 70, and a locking assembly 80.

[0104] Both the positioning mechanism 30 and the support mechanism 40 are attached to the floating platform 10. The floating platform 10 is floatingly connected to the lifting platform 60. The lifting mechanism 70 is connected between the lifting platform 60 and the moving base 50 and is used to lift the lifting platform 60. The locking assembly 80 is used to lock the floating platform 10 to the lifting platform 60 or release the lifting platform 60 from the floating platform 10.

[0105] The positioning mechanism 30 includes a driving member 31, a positioning member 32, a transmission assembly 33, a first mounting seat 34, a connecting plate 35, a first guide shaft 36, and a first detection unit 37. The first mounting seat 34 is fixed to the floating platform 10. The transmission assembly 33 includes a first gear 331, a second gear 332, and a lead screw 333. The first gear 331 is connected to the output end of the driving member 31, the first gear 331 meshes with the second gear 332, and the second gear 332 is fitted on and threadedly engages with the lead screw 333. The positioning member 32 is indirectly connected to the lead screw 333 via the connecting plate 35. The first guide shaft 36 is slidably inserted into a first guide hole 341 of the first mounting seat 34. Insertion and connected to a connecting plate 35. The driving member 31 and the positioning member 32 are drivably connected via a transmission assembly 33, which drives the positioning member 32 to move along the height direction of the battery exchange device 100. The first detection unit 37 is used to detect height information of the positioning member 32.

[0106] The support mechanism 40 includes a second mounting seat 41, a support member 42, an elastic member 43, a second guide shaft 44, and a second detection unit 45. The second mounting seat 41 is fixed to the floating platform 10, the elastic member 43 is elastically supported between the support member 42 and the second mounting seat 41, and the support member 42 is used to support the battery 2000. The second guide shaft 44 is slidably inserted into a second guide hole 411 of the second mounting seat 41. Insertion and connected to the support member 42. The second detection unit 45 is used to detect whether the support member 42 is in contact with the battery 2000.

[0107] The locking assembly 80 includes an electromagnet 81 installed on the lifting platform 60 and a magnetic attraction plate 82 installed on the floating platform 10, and the electromagnet 81 and the magnetic attraction plate 82 cooperate to lock the floating platform 10 to the lifting platform 60 or release the floating platform 10 from the lifting platform 60.

[0108] The operating principle of the battery exchange device 100 is as follows: when it is necessary to remove the battery 2000 of the power consuming device, the floating platform 10 is unlocked from the lifting platform 60 by the locking assembly 80, the lifting mechanism 70 lifts the lifting platform 60, and the driving member 31 drives to raise the positioning member 32, thereby positioning and engaging the positioning member 32 with the power consuming device and causing the support member 42 to support the battery 2000. The floating platform 10 is locked to the lifting platform 60 by the locking assembly 80. The locking / unlocking mechanism 20 operates to remove the battery 2000 from the power consuming device until the battery 2000 is completely detached from the power consuming device. The lift mechanism 70 lowers the lifting platform 60, and the drive member 31 drives the positioning member 32 to lower it, disengaging the positioning member 32 from the power consumption device, and the gears 53 and rollers 54 of the moving base 50 rotate to move the battery exchange device 100, thereby moving the battery 2000.

[0109] When the battery 2000 needs to be attached to the power consuming device, the floating platform 10 is locked to the lifting platform 60 by the locking assembly 80, and the lifting mechanism 70 lowers the lifting platform 60 to its lowest point, supporting the battery 2000 on the support member 42. The gears 53 and rollers 54 of the moving base 50 rotate, moving the battery exchange device 100 loaded with the battery 2000 to the battery exchange device 100. The floating platform 10 is unlocked from the lifting platform 60 by the locking assembly 80, the lifting mechanism 70 lifts the lifting platform 60, and the driving member 31 drives the positioning member 32 to lift, thereby positioning and fitting the positioning member 32 to the power consuming device and aligning the battery 2000 and the power consuming device for installation. The locking / unlocking mechanism 20 operates to attach the battery 2000 to the power consuming device. The lift mechanism 70 lowers the lift platform 60, and the drive member 31 drives the positioning member 32 to lower it.

[0110] An embodiment of the present application further provides a battery exchange system 1000 that includes a rail 300, a battery exchange platform 400, a battery insertion / removal device 200, and the battery exchange device 100 provided by any of the above embodiments, wherein the battery exchange device 100 is movably installed on the rail 300, the battery exchange platform 400 is located at one end of the rail 300, and the battery insertion / removal device 200 is located at the other end of the rail 300.

[0111] The battery exchange platform 400 is used to park a vehicle, and the vehicle exchanges the battery 2000 on the battery exchange platform 400. The battery exchange platform 400 is used to lift the entire vehicle, and the vehicle is positioned above the battery exchange platform 400. The battery insertion / removal device 200 is used to remove the battery 2000 to be charged from the battery exchange device 100 or to place the battery 2000 on the battery exchange device 100.

[0112] The operation process of the battery exchange system 1000 will be described using the case where the battery 2000 that has run out of electrical energy is removed from the vehicle 3000 as an example.

[0113] As shown in Figures 13 to 18, the vehicle 3000 is parked on the battery exchange platform 400, and the vehicle 3000 is lifted off the ground by the battery exchange platform 400. The battery exchange apparatus 100 moves along the rails 300 to a position directly opposite the battery 2000 below the vehicle 3000. The scissor-type lift mechanism 70 drives the lifting platform 60 to lift, and the driving member 31 drives the positioning member 32 to lift and extend from the protective cover 90 until the positioning member 32 and the vehicle 3000 complete their positioning and engagement. The lock / unlock mechanism 20 unlocks the battery 2000 from the vehicle 3000, and the battery 2000 drops completely onto the battery exchange apparatus 100. After the battery 2000 has completely dropped into the battery exchange apparatus 100, the scissor lift mechanism 70 drives and lowers the lock / unlock mechanism 20, thereby completely detaching the battery 2000 from the vehicle 3000, and the drive member 31 drives and lowers the positioning member 32. The battery exchange apparatus 100 moves along the rails 300 to the battery insertion / removal apparatus 200, and the battery insertion / removal apparatus 200 removes the battery 2000 from the exchange apparatus 100.
