Description

Technical Field

[0001] This application belongs to the field of vehicle battery swapping technology, specifically relating to a manual battery swapping device. Background Technology

[0002] Compared with traditional gasoline-powered vehicles, electric vehicles have advantages such as being green and environmentally friendly and having a high degree of intelligence. They are of great significance for energy conservation, emission reduction, and intelligent urban transportation, and are therefore gradually becoming the strategic development direction of the future automotive industry.

[0003] Existing electric vehicle charging methods typically fall into two categories: battery swapping and direct charging. Current technology involves building corresponding battery swapping stations for electric vehicles requiring battery swapping, allowing users to drive to these stations for replacement. However, in practice, there are instances where electric vehicles are unable to reach a swapping station due to insufficient power, necessitating manual battery swapping equipment to transport the battery to the vehicle's location. Because electric vehicles come in various types, their corresponding battery models and styles differ, resulting in varying battery pack dimensions. However, existing manual battery swapping equipment can only handle one type of battery pack, making it inconvenient to swap different battery pack sizes. Utility Model Content

[0004] This application provides a manual battery swapping device to solve the problem that existing manual battery swapping devices are incompatible with battery packs of different specifications to achieve battery swapping operations.

[0005] The technical solution adopted in this application is as follows:

[0006] A manual battery swapping device is used to swap batteries in electric vehicles. The manual battery swapping device includes:

[0007] Support device for supporting the battery pack to be replaced after being removed from the electric vehicle;

[0008] An unlocking device, located on the support device, is used to unlock the locking device that secures the battery pack to the electric vehicle, so that the battery pack to be replaced can be removed from the electric vehicle.

[0009] A positioning device is mounted on a support device. The positioning device includes a first positioning part for cooperating with the body of an electric vehicle and a second positioning part for cooperating with a battery pack. There are two of each of the first and second positioning parts. The two first positioning parts and the two second positioning parts are symmetrically arranged along the length direction of the electric vehicle body. The mounting position of at least one first positioning part and at least one second positioning part on the support device is adjustable along the width direction of the electric vehicle body.

[0010] This solution uses a support device to support the battery pack to be replaced, thereby ensuring the stability of the battery pack on the battery swapping equipment and thus guaranteeing the reliability of the equipment during the swapping process. At the same time, an unlocking device is installed on the support device to unlock the battery pack from the vehicle side while supporting and positioning it, so as to realize the disassembly and transfer of the battery pack to be replaced by the battery swapping equipment.

[0011] Meanwhile, this solution also sets up a first positioning part and a second positioning part to cooperate with the electric vehicle and the battery pack to be replaced respectively for dual positioning. The first positioning part and the second positioning part are symmetrically arranged to achieve symmetrical positioning of the electric vehicle and the battery pack from both sides, thereby further improving the positioning stability and accuracy and enhancing the reliability of the battery swapping equipment.

[0012] Furthermore, by adjusting the installation positions of the first and second positioning parts along the vehicle's width, and based on actual application scenarios and docking requirements, a single battery swapping device can be positioned to swap battery packs of different widths. This enables compatible battery swapping for battery packs of varying widths, reducing swapping costs and improving the device's practicality. By adjusting the installation positions of the first and second positioning parts, adaptability to battery packs of different widths is achieved. This method requires only adjustments to the first and second positioning parts, resulting in minimal changes to the overall structure of the battery swapping device, low operational difficulty, and rapid adjustment capabilities.

[0013] In a preferred embodiment of a manual battery swapping device, the positioning device further includes a first connecting plate and a second connecting plate fixed to the support device. The first connecting plate is provided with a plurality of first mounting positions arranged along the width direction of the electric vehicle body to install the first positioning part, and the second connecting plate is provided with a plurality of second mounting positions arranged along the width direction of the electric vehicle body to install the second positioning part, and the first mounting positions and the second mounting positions are arranged in a one-to-one correspondence.

[0014] This solution uses a first connecting plate and a second connecting plate to limit and fix the first and second positioning parts on the support device. This allows the first and second positioning parts to position the battery pack at the support device, enabling precise unlocking of the battery pack and improving the positional stability of the support device when supporting the battery pack. Multiple first and second mounting positions allow the first and second positioning parts to be adjusted along the width direction simply by changing their positions on the first and second connecting plates. This enables the installation and removal of battery packs of different widths without moving other components, making operation convenient and reducing manufacturing costs by eliminating the need for rearranging or altering the support device.

[0015] In a preferred embodiment of a manual battery swapping device, the support device includes a lower bracket and an upper bracket. A first connecting plate is fixed to the lower bracket, and a second connecting plate is fixed to the upper bracket. The upper bracket can move relative to the lower bracket along the length of the electric vehicle body, making the distance between the first positioning part and the second positioning part adjustable.

[0016] This design uses a first positioning part and a second positioning part, which are fixed in place on the support device via a first connecting plate and a second connecting plate. Since the battery pack to be replaced has a certain weight, the first and second connecting plates connect the lower and upper brackets respectively, which helps to distribute the force and prevents excessive stress on a single support layer, thus avoiding instability of the support device. Simultaneously, the movement of the upper bracket relative to the lower bracket allows for adjustment of the distance between the first and second positioning parts, enabling adaptable positioning for battery packs of different lengths, thereby facilitating the installation and removal of battery packs of varying lengths.

[0017] In a preferred embodiment of a manual battery swapping device, the first mounting position and the second mounting position are respectively provided with mounting holes for fixing the first positioning part and the second positioning part, and the first positioning part and the second positioning part are fixed to the corresponding mounting holes by fasteners.

[0018] This solution uses fasteners to fix the first and second positioning parts to their respective mounting holes. This positioning method is simple and effective, and the machining process for setting the mounting holes is simple and easy, facilitating the disassembly and repositioning of the first and second positioning parts. Furthermore, the mounting holes occupy a small area at the first and second mounting positions, allowing for the machining of multiple mounting holes.

[0019] In a preferred embodiment of a manual battery swapping device, the unlocking device includes an unlocking pin disposed on a support device, the mounting position of which on the support device is adjustable along the width direction of the electric vehicle body.

[0020] This solution involves placing an unlocking pin on the support device. When positioning and supporting the battery pack to be replaced, the battery pack can be unlocked using the unlocking pin located on the support device. The shape and unlocking method of the unlocking pin can utilize existing technologies. This solution also allows the unlocking pin to adjust its installation position along the width of the vehicle body, enabling the unlocking pin to cooperate with the first positioning part and the second positioning part to adjust its installation position, thereby achieving adaptive unlocking for battery packs of different widths and further improving the compatibility and practicality of the battery swapping equipment.

[0021] In a preferred embodiment of a manual battery swapping device, the unlocking device further includes a third connecting plate fixed to the upper bracket. The third connecting plate has multiple third mounting positions arranged along the width direction of the electric vehicle body for installing unlocking pins.

[0022] This solution uses a third connecting plate to limit and fix the unlocking pin in the support device, enabling precise unlocking of the battery pack at the support device and enhancing the positional stability of the support device when supporting the battery pack. Multiple third mounting positions allow the unlocking pin to be adjusted along the width direction simply by changing its position on the third connecting plate. This enables the removal of battery packs of different widths without moving other components, simplifying operation and reducing manufacturing costs by eliminating the need for rearranging or altering the support device.

[0023] In a preferred embodiment of a manual battery swapping device, the positioning device further includes a limiting pad detachably connected to the first positioning part and the second positioning part. The highest point of the first positioning part and the second positioning part is higher than the upper surface of the limiting pad. At least a portion of the limiting pad extends out of the first positioning part or the second positioning part along the width direction of the electric vehicle body to support the battery bracket on the electric vehicle used for installing the battery pack.

[0024] This solution incorporates a limiting pad, the portion of which extends beyond the first or second positioning part along the vehicle's width. This increases the limiting contact area between the positioning device and the electric vehicle. The limiting pad, in conjunction with the first and second positioning parts, ensures the battery mount is stably supported by the battery swapping equipment. When installing or removing the battery mount, operators no longer need to manually support it from multiple directions; a single person can complete the installation or removal. Furthermore, the highest points of the first and second positioning parts are higher than the upper surface of the limiting pad, ensuring that the limiting pad does not interfere with the fit between the first positioning part and the vehicle body, or the fit between the second positioning part and the battery pack.

[0025] In addition, the detachable connection of the limiting pad allows it to be assembled into the first and second positioning parts only when the electric vehicle battery bracket needs to be installed or removed, and its small size makes it easy to store and install.

[0026] In a preferred embodiment of a manual battery swapping device, both the first positioning part and the second positioning part are provided with a downwardly recessed positioning groove, and the bottom of the limiting pad is provided with a notch that engages with the bottom of the positioning groove.

[0027] This solution utilizes the recessed shapes of the first and second positioning parts to create a matching notch in the limiting pad, allowing the notch to engage with the positioning groove. This enables the limiting pad to be positioned and installed in the first and second positioning parts. This method simplifies assembly and disassembly, and when the limiting pad is subjected to pressure from the electric vehicle's battery bracket, it can fit more tightly into the positioning groove, further enhancing its positioning stability and thus helping to improve the support stability of the battery bracket.

[0028] In a preferred embodiment of a manual battery swapping device, the limiting pad has a through hole extending along the width direction of the electric vehicle body, and a fastener is inserted into the through hole to fix it to the first positioning part and the second positioning part.

[0029] This solution uses fasteners to fix the limiting pad to the first and second positioning parts, which helps to enhance the installation and positioning effect of the limiting pad and prevents the limiting pad from shifting or tilting due to collisions. This ensures that the position of the limiting pad is accurately defined, providing stable support for the electric vehicle battery bracket and further enhancing the overall stability of the battery swapping equipment in conjunction with the positioning device.

[0030] In a preferred embodiment of a manual battery swapping device, the battery swapping device includes a movable device disposed below a support device and a handrail disposed on the movable device. The handrail is used to be forced to move the movable device and thus move the support device to be below the electric vehicle for battery swapping. And / or, the battery swapping device includes a lifting device disposed below the support device, which can move the support device vertically to match the height position of the battery pack.

[0031] This solution incorporates handrails to facilitate manual movement of the battery swapping equipment by operators, reducing workload and allowing for rapid relocation to the electric vehicle. A lifting device moves the support structure to a suitable height, enabling the removal of the battery pack from under the electric vehicle.

[0032] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0033] This solution uses a support device to support the battery pack to be replaced, thereby ensuring the stability of the battery pack on the battery swapping equipment and thus guaranteeing the reliability of the equipment during the swapping process. At the same time, an unlocking device is installed on the support device to unlock the battery pack from the vehicle side while supporting and positioning it, so as to realize the disassembly and transfer of the battery pack to be replaced by the battery swapping equipment.

[0034] Meanwhile, this solution also sets up a first positioning part and a second positioning part to cooperate with the electric vehicle and the battery pack to be replaced respectively for dual positioning. The first positioning part and the second positioning part are symmetrically arranged to achieve symmetrical positioning of the electric vehicle and the battery pack from both sides, thereby further improving the positioning stability and accuracy and enhancing the reliability of the battery swapping equipment.

[0035] Furthermore, by adjusting the installation positions of the first and second positioning parts along the vehicle's width, and based on actual application scenarios and docking requirements, a single battery swapping device can be positioned to swap battery packs of different widths. This enables compatible battery swapping for battery packs of varying widths, reducing swapping costs and improving the device's practicality. By adjusting the installation positions of the first and second positioning parts, adaptability to battery packs of different widths is achieved. This method requires only adjustments to the first and second positioning parts, resulting in minimal changes to the overall structure of the battery swapping device, low operational difficulty, and rapid adjustment capabilities.

[0057] This application provides a manual battery swapping device, such as Figures 1 to 8 As shown, the battery swapping equipment is used to swap batteries for electric vehicles. The manual battery swapping equipment includes:

[0058] Support device 100 is used to support the battery pack to be replaced after being removed from the electric vehicle;

[0059] Unlocking device 200, provided on support device 100, is used to unlock the locking device that locks the battery pack to the electric vehicle, so that the battery pack to be replaced can be removed from the electric vehicle;

[0060] A positioning device 300 is disposed on a support device 100. The positioning device 300 includes a first positioning part 310 for cooperating with the body of an electric vehicle and a second positioning part 320 for cooperating with a battery pack. There are two of each of the first positioning part 310 and the second positioning part 320. The two first positioning parts 310 and the two second positioning parts 320 are symmetrically arranged along the length direction of the electric vehicle body. The mounting position of at least one first positioning part 310 and at least one second positioning part 320 on the support device 100 is adjustable along the width direction of the electric vehicle body.

[0061] This solution uses a support device 100 to support the battery pack to be replaced, thereby ensuring the stability of the battery pack on the battery swapping equipment and thus guaranteeing the reliability of the equipment during the swapping process. At the same time, an unlocking device 200 is provided on the support device 100. While supporting and positioning the battery pack, the unlocking device 200 unlocks the battery pack from the vehicle side, enabling the battery swapping equipment to disassemble and transport the battery pack to be replaced.

[0062] Meanwhile, this solution also sets up a first positioning unit 310 and a second positioning unit 320 to cooperate with the electric vehicle and the battery pack to be replaced respectively for dual positioning. The first positioning unit 310 and the second positioning unit 320 are symmetrically arranged to achieve symmetrical positioning of the electric vehicle and the battery pack from both sides, thereby further improving the positioning stability and accuracy and enhancing the reliability of the battery swapping equipment.

[0063] Furthermore, by adjusting the installation positions of the first positioning part 310 and the second positioning part 320 along the width of the vehicle body, and by installing the first positioning part 310 and the second positioning part 320 according to the actual application scenario and actual docking requirements, a single battery swapping device can be positioned for battery packs of different widths via the first positioning part 310 and the second positioning part 320. This achieves compatible battery swapping for battery packs of different widths, which helps reduce battery swapping costs and improves the practicality of the battery swapping device. By adjusting the installation positions of the first positioning part 310 and the second positioning part 320, adaptability positioning for battery packs of different widths is achieved. When making adaptability adjustments for battery packs of different widths, only the first positioning part 310 and the second positioning part 320 need to be adjusted, resulting in minimal changes to the overall structure of the battery swapping device, low operational difficulty, and the ability to make rapid adjustments.

[0064] In one embodiment, such as Figures 1 to 4 As shown, the positioning device 300 also includes a first connecting plate 330 and a second connecting plate 340 fixed to the support device 100. The first connecting plate 330 is provided with a plurality of first mounting positions 331 arranged along the width direction of the electric vehicle body to mount the first positioning part 310. The second connecting plate 340 is provided with a plurality of second mounting positions 341 arranged along the width direction of the electric vehicle body to mount the second positioning part 320. The first mounting positions 331 and the second mounting positions 341 are arranged in a one-to-one correspondence.

[0065] This solution uses a first connecting plate 330 and a second connecting plate 340 to limit and fix the first positioning part 310 and the second positioning part 320 on the support device 100. This allows the first positioning part 310 and the second positioning part 320 to position the battery pack at the support device 100, enabling precise unlocking of the battery pack and improving the positional stability of the support device 100 when supporting the battery pack. Multiple first mounting positions 331 and multiple second mounting positions 341 allow the first positioning part 310 and the second positioning part 320 to be adjusted along the width direction simply by changing their positions on the first connecting plate 330 and the second connecting plate 341. This enables the installation and removal of battery packs of different widths without moving other components, making operation convenient and eliminating the need for rearranging or altering the support device 100, thus reducing manufacturing costs.

[0066] Furthermore, such as Figures 1 to 4 As shown, the support device 100 includes a lower bracket 120 and an upper bracket 110. A first connecting plate 330 is fixed to the lower bracket 120, and a second connecting plate 340 is fixed to the upper bracket 110. The upper bracket 110 can move relative to the lower bracket 120 along the length of the electric vehicle body, so that the distance between the first positioning part 310 and the second positioning part 320 is adjustable.

[0067] This design uses a first positioning part 310 and a second positioning part 320, which are fixed in place on the support device 100 via a first connecting plate 330 and a second connecting plate 340. Since the battery pack to be replaced has a certain weight, the first connecting plate 330 and the second connecting plate 340 connect the lower bracket 120 and the upper bracket 110 respectively, which helps to distribute the force and prevents excessive force on a single layer of support from causing instability in the support device 100. Simultaneously, the movement of the upper bracket 110 relative to the lower bracket 120 allows the distance between the first positioning part 310 and the second positioning part 320 to be adjusted, achieving adaptable positioning for battery packs of different lengths, thus enabling the installation and removal of battery packs of different lengths.

[0068] In one implementation, such as Figure 5 , Figure 6As shown, relative movement between the upper bracket 110 and the lower bracket 120 is achieved by setting a sliding assembly 150 connected to the upper bracket 110. The sliding assembly 150 includes a slider 151, a bracket guide rail 152, and a drive unit 153. The slider 151 is connected to the upper bracket 110, the bracket guide rail 152 is disposed on the lower bracket 120, the slider 151 is disposed on the bracket guide rail 152, and the drive unit 153 is used to apply a force to the upper bracket 110 to make the upper bracket 110 slide relative to the bracket guide rail 152. The sliding assembly 150 enables the sliding adjustment of the upper bracket 110, improving the flexibility of the battery swapping equipment, allowing the upper bracket 110 to slide to a suitable position for battery swapping according to actual conditions.

[0069] In one embodiment, such as Figure 3 , Figure 4 As shown, the first mounting position 331 and the second mounting position 341 are respectively provided with mounting holes 332 for fixing the first positioning part 310 and the second positioning part 320. The first positioning part 310 and the second positioning part 320 are fixed to the corresponding mounting holes 332 by fasteners.

[0070] This solution uses fasteners to fix the first positioning part 310 and the second positioning part 320 to the corresponding mounting holes 332. This positioning method is simple and effective, and the machining of the mounting holes 332 is simple and easy, facilitating the disassembly and repositioning of the first positioning part 310 and the second positioning part 320. Furthermore, the mounting holes 332 occupy a small area in the first mounting position 331 and the second mounting position 341, thus enabling the machining of multiple mounting holes 332.

[0071] Understandably, the first positioning unit 310 and the second positioning unit 320 are installed in a similar manner. Figure 3 The enlarged view of the second positioning part 320 is used as an example for identification.

[0072] In one embodiment, such as Figure 3 As shown, the unlocking device 200 includes an unlocking pin 210 disposed on the support device 100, and the mounting position of the unlocking pin 210 on the support device 100 is adjustable along the width direction of the electric vehicle body.

[0073] This solution involves setting the unlocking pin 210 on the support device 100. When positioning and supporting the battery pack to be replaced, the battery pack can be unlocked by the unlocking pin 210 located on the support device 100. The shape and unlocking method of the unlocking pin 210 can be obtained using existing technology. This solution also allows the unlocking pin 210 to adjust its installation position along the width of the vehicle body, so that the unlocking pin 210 can cooperate with the first positioning part 310 and the second positioning part 320 to adjust its installation position, thereby achieving adaptive unlocking for battery packs of different widths and further improving the compatibility and practicality of the battery swapping equipment.

[0074] Preferably, the unlocking device 200 further includes a third connecting plate 220 fixed to the upper bracket 110. The third connecting plate 220 is provided with a plurality of third mounting positions 221 arranged along the width direction of the electric vehicle body for mounting the unlocking pin 210.

[0075] This solution uses a third connecting plate 220 to limit and fix the unlocking pin 210 on the support device 100, thereby enabling the unlocking pin 210 to accurately unlock the battery pack at the support device 100 and improving the positional stability of the support device 100 when supporting the battery pack. Multiple third mounting positions 221 allow the unlocking pin 210 to be adjusted along its width by changing its position on the third connecting plate 220, thus enabling the disassembly of battery packs of different widths without moving other components. This facilitates operation and eliminates the need for rearranging or altering the support device 100, reducing manufacturing costs.

[0076] In one embodiment, such as Figure 4 , Figure 7 As shown, the positioning device 300 also includes a limiting pad 360 detachably connected to the first positioning part 310 and the second positioning part 320. The highest point of the first positioning part 310 and the second positioning part 320 is higher than the upper surface of the limiting pad 360. At least a portion of the limiting pad 360 extends out of the first positioning part 310 or the second positioning part 320 along the width direction of the electric vehicle body to support the battery bracket on the electric vehicle for installing the battery pack.

[0077] This solution, by setting a limiting pad 360, the portion of which extends out of the first positioning part 310 or the second positioning part 320 along the width direction of the vehicle body, helps to increase the limiting contact area between the positioning device 300 and the electric vehicle. The limiting pad 360 cooperates with the first positioning part 310 and the second positioning part 320 to ensure that the battery bracket 600 of the electric vehicle can be stably supported by the battery swapping equipment. When it is necessary to install and remove the battery bracket 600, the operator does not need to manually support the battery bracket 600 in multiple directions, and a single person can complete the removal or installation of the battery bracket 600.

[0078] In addition, the highest points of the first positioning part 310 and the second positioning part 320 are higher than the upper surface of the limiting pad 360, so that the setting of the limiting pad 360 will not affect the cooperation between the first positioning part 310 and the vehicle body and the cooperation between the second positioning part 320 and the battery pack.

[0079] Furthermore, the detachable connection of the limiting pad 360 allows it to be assembled with the first positioning part 310 and the second positioning part only when the electric vehicle battery bracket 600 needs to be installed and removed, and its small size makes it easy to store and install.

[0080] As a preferred embodiment, such as Figure 3 As shown, both the first positioning part 310 and the second positioning part 320 are provided with a downwardly recessed positioning groove 350, and the bottom of the limiting pad 360 is provided with a notch 361 that engages with the bottom of the positioning groove 350.

[0081] This solution utilizes the recessed shape of the first positioning part 310 and the second positioning part 320 to provide a matching notch 361 in the limiting pad 360, allowing the notch 361 to engage with the positioning groove 350. This enables the limiting pad 360 to be positioned and installed in the first positioning part 310 and the second positioning part 320. This method simplifies assembly and disassembly, and when the limiting pad 360 is subjected to pressure from the battery bracket 600 of the electric vehicle, it can fit more tightly into the positioning groove 350, further enhancing its positioning stability and thus helping to improve the support stability of the battery bracket 600.

[0082] Furthermore, such as Figure 8 As shown, the limiting pad 360 has a through hole 362 extending along the width direction of the electric vehicle body, and a fastener is inserted into the through hole 362 to fix it to the first positioning part 310 and the second positioning part 320.

[0083] This solution uses fasteners to fix the limiting pad 360 to the first positioning part 310 and the second positioning part 320, which enhances the installation and positioning effect of the limiting pad 360 and prevents the limiting pad 360 from shifting or tilting due to collisions. This ensures accurate positioning of the limiting pad 360, providing stable support for the electric vehicle battery bracket 600, and further improving the overall stability of the battery swapping equipment in conjunction with the positioning device 300. In this embodiment, screws or other existing technologies can be used as fasteners to achieve the positioning and installation of the limiting pad 360 in the first positioning part 310 and the second positioning part 320.

[0084] When the manual battery swapping device of this application is used to install or remove the battery bracket, the first positioning part 310 cooperates with the locking base 610 on the battery bracket 600. Specifically, part of the positioning groove 350 of the first positioning part 310 engages with both sides of the locking base 610, while the battery bracket 600 is supported by the limiting pads 360 installed on the first positioning part 310 and the second positioning part 320, so that the operator can install or remove the battery bracket 600. This design allows a single person to complete the installation and removal of the battery bracket without the need for other tools or multiple people working together.

[0085] In other embodiments, a positioning block matching the first positioning part 310 can be provided on the battery holder 600. For example, the positioning block can be provided with a claw that engages with the top of the first positioning part 310. The first positioning part 310 can be raised with the support device until the claw of the positioning block engages with the first positioning part 310, thereby preventing the positioning block from moving. Thus, by limiting the positioning block, the first positioning part 310 limits the battery holder 600 in the horizontal direction. At the same time, the limiting pad 360 located on the first positioning part 310 abuts against the bottom surface of the battery holder 600, and the engagement between the first positioning part 310 and the positioning block prevents the battery holder 600 from moving vertically downward. The two opposing first positioning parts 310 limit the opposite sides of the battery holder 600. At the same time, the limiting pad 360 provided on the second positioning part 320 further supports and limits the battery holder 600, realizing the opposing connection between the positioning device 300 and the battery holder 600, thereby performing or installing the battery holder 600.

[0086] In an embodiment, such as Figure 1 As shown, the battery swapping equipment includes a movable device disposed below the support device 100 and a handrail 400 disposed on the movable device. The handrail 400 is used to be forced to move the movable device and thus move the support device 100 to be under the electric vehicle for battery swapping; and / or, the battery swapping equipment includes a lifting device 500 disposed below the support device 100. The lifting device 500 can move the support device 100 vertically to adapt to the height position of the battery pack.

[0087] Preferably, the lifting device 500 adopts a scissor lift mechanism, and the power swapping equipment is installed on the lifting platform of the scissor lift mechanism.

[0088] In this embodiment, the moving device is implemented using casters 510. Of course, the moving device can also adopt other structures depending on the actual situation, as long as it can drive the manual battery swapping equipment of this application to move.

[0089] This solution incorporates a handrail 400 to facilitate manual movement of the battery swapping equipment by operators, reducing workload and allowing for rapid relocation of the equipment to the electric vehicle. The lifting device 500 moves the support device 100 to a suitable height, enabling the removal of the battery pack to be swapped from under the electric vehicle.

[0090] In a preferred embodiment, such as Figure 1 As shown, the handrail 400 is located at one end of the manual battery swapping device along the length direction of the manual battery swapping device (corresponding to the body length direction of the electric vehicle) near the second positioning part 320, so that when the manual battery swapping device needs to replace the battery pack of the electric vehicle, it can be pushed into the bottom of the electric vehicle from the rear direction to perform the battery swapping operation.

[0091] In another preferred embodiment, the handrail is located at any end of the manual battery swapping device along the width direction of the manual battery swapping device (corresponding to the width direction of the electric vehicle body), so that when the manual battery swapping device needs to replace the battery pack of the electric vehicle, it can be pushed into the bottom of the electric vehicle from one side of the vehicle body to perform the battery swapping operation.

[0092] In addition, such as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the support device 100 of this application also includes a tray 130 for supporting the battery pack. The tray 130 also includes a support assembly 140 disposed between the tray 130 and the upper bracket 110. The support assembly 140 includes an elastic member 142 and a base 141. The base 141 is fixed to the upper bracket 110. Both ends of the elastic member 142 are respectively fixed to the tray 130 and the base 141, and a limiting sleeve 143 fixed to the base 141 is fitted onto the outside of the elastic member 142. Increasing the contact area between the tray 130 and the battery pack improves the stability of the load-bearing support and avoids excessive stress concentration.

[0093] Furthermore, the base 141 is provided with multiple first positioning holes for fixing the elastic element 142, and the upper bracket 110 is provided with multiple second positioning holes for fixing the base 141. The positioning of the elastic element 142 can be adjusted according to actual needs. This method is not shown in the figure, but referring to the figure, multiple first positioning holes are opened in the base 141 along the length direction of the vehicle body, and multiple second positioning holes are provided in the upper bracket 110 along the length direction of the vehicle body, so as to realize the adjustment of the fixing position of the base 141 and the fixing position of the elastic element 142. In this embodiment, the elastic element 142 is a spring.

[0094] Preferably, the second connecting plate 340 extends along the top surface of the upper bracket 110 to form the base 141. Matching the positioning of the elastic element 142 with the positioning of the second positioning fork helps to further improve positioning accuracy and stability. Furthermore, this method allows the base 141 and the second connecting plate 340 to be integrally formed, which improves machining accuracy and reduces assembly steps.
