Description

Technical Field

[0001] This utility model relates generally to the technical field of battery swapping stations, and more specifically to a battery lifting device and a battery swapping station. Background Technology

[0002] Currently, with the widespread application of battery swapping stations, higher demands are being placed on the user experience of these stations.

[0003] In existing technologies, when a battery swapping station retrieves a battery, a mechanism needs to reach under the vehicle to remove the battery, which requires lifting the vehicle.

[0004] The battery take-up mechanism is generally a scissor-fork lifting mechanism. In order to reduce the height of the vehicle and obtain a better battery swapping experience, the height of the battery take-up mechanism needs to be reduced. This results in a large pressure angle for the battery take-up mechanism, requiring a driving component with a large driving force to lift the mechanism, which increases manufacturing costs. Utility Model Content

[0005] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0006] To at least partially solve the above problems, the first aspect of this utility model provides a battery lifting device, the lifting device comprising: Fixing plate; A lifting plate, which is arranged above the fixed plate along the height direction of the lifting device; A scissor fork, which is disposed between the fixed plate and the lifting plate, is used to support the lifting plate; The transmission assembly includes: A track board, movably connected to the fixed plate along a first horizontal direction, the track board having an inclined surface at an angle to the horizontal plane containing the first horizontal direction; and A drive wheel, the drive wheel being disposed on the lifting plate and abutting against the inclined surface; and A driving component is disposed on the fixed plate and connected to the track plate, and the driving component is used to drive the track plate along the first horizontal direction.

[0007] According to the battery lifting device of the first aspect of this utility model, when the driving component drives the track plate along the first horizontal direction, due to the inclined surface of the track plate, a driving force along the height direction is exerted on the transmission wheel. Under the combined action of the lifting plate and the gravity of the battery on it, the lifting plate is driven to rise and fall along the height direction. Since the driving component drives the track plate along the first horizontal direction, and the angle between the inclined surface of the track plate and the horizontal plane is consistent, the driving force transmitted by the driving component to the transmission wheel can remain stable. The lifting device will not require a large driving force due to an excessively large pressure angle, thereby reducing the requirements of the lifting device on the driving component and reducing the manufacturing cost of the lifting device. This makes the driving of the lifting device more stable, and the height of the lifting device will not be too large, so as not to increase the lifting height of the vehicle and affect the battery swapping experience of the vehicle driver.

[0014] Optionally, the lifting device includes at least two scissor forks, which are respectively arranged on both sides of the driving member along a second horizontal direction perpendicular to the first horizontal direction.

[0015] Optionally, the lifting plate is provided with a maintenance weight reduction groove, and at least a portion of the maintenance weight reduction groove has its projection along the height direction overlapping with the projection of at least one of the scissor fork, the driving member, and the transmission assembly along the height direction.

[0016] A second aspect of this invention provides a battery swapping station, including a battery lifting device as described above.

[0017] According to the second aspect of the present invention, the requirements of the lifting device for the driving components are reduced, making the driving of the lifting device more stable and reducing the manufacturing cost of the lifting device and the battery swapping station. At the same time, the height of the lifting device will not be too large, so as not to increase the lifting height of the vehicle and affect the battery swapping experience of the vehicle driver.

[0024] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0025] Figures 1 to 4A battery lifting device 100 according to the present invention is shown. The lifting device 100 includes a fixed plate 110, a lifting plate 120, a scissor fork 130, a transmission assembly 140, and a drive component 150. The lifting plate 120 is arranged above the fixed plate 110 along the height direction D3 of the lifting device 100. The scissor fork 130 is disposed between the fixed plate 110 and the lifting plate 120 for supporting the lifting plate 120.

[0026] The transmission assembly 140 includes a track plate 141 and a drive wheel 142. The track plate is movably connected to a fixed plate 110 along a first horizontal direction D1. The track plate 141 has an inclined surface 143, which forms an angle with the horizontal plane containing the first horizontal direction D1. The drive wheel 142 is disposed on a lifting plate 120 and abuts against the inclined surface 143. A drive member 150 is disposed on the fixed plate 110 and connected to the track plate 141. The drive member 150 is used to drive the track plate 141 along the first horizontal direction D1.

[0027] According to the battery lifting device 100 of this utility model, when the driving member 150 drives the track plate 141 along the first horizontal direction D1, the inclined surface 143 of the track plate 141 provides a driving force on the transmission wheel 142 along the height direction D3. With the cooperation of the lifting plate 120 and the gravity of the battery on it, the lifting plate 120 is driven to rise and fall along the height direction D3. Since the drive component 150 drives the track plate 141 along the first horizontal direction D1, and the angle between the inclined surface 143 of the track plate 141 and the horizontal plane is consistent, the driving force transmitted by the drive component 150 to the transmission wheel 142 can remain stable. The lifting device 100 will not require a large driving force due to an excessive pressure angle, thereby reducing the requirements of the lifting device 100 on the drive component 150 and reducing the manufacturing cost of the lifting device 100. This makes the drive of the lifting device 100 more stable, and the height of the lifting device 100 will not be too large, so as not to increase the vehicle's lifting height and affect the battery swapping experience of the vehicle driver.

[0028] In some specific embodiments of this utility model, refer to Figure 1 and Figure 2The scissor fork 130 includes a first link 131 and a second link 132. The middle portion of the first link 131 is rotatably connected to the middle portion of the second link 132. The first end of the first link 131 is rotatably connected to the fixed plate 110, and the second end of the first link 131 is rotatably connected to the lifting plate 120 and movably connected to the lifting plate 120 along the first horizontal direction D1. The first end of the second link 132 is rotatably connected to the lifting plate 120, and the second end of the second link 132 is rotatably connected to the fixed plate 110 and movably connected to the lifting plate 120 along the first horizontal direction D1. The scissor fork 130 ensures stable transmission between the lifting plate 120 and the fixed plate 110 along the height direction D3, allowing the lifting plate 120 to rise and fall stably along the height direction D3, thus facilitating accurate battery installation and removal.

[0029] In some specific embodiments of this utility model, refer to Figure 1 The lifting device 100 includes two scissor forks 130. Along a second horizontal direction D2 perpendicular to the first horizontal direction D1, the two scissor forks 130 are respectively arranged on both sides of the driving member 150, further improving the stability of the lifting plate 120's lifting movement relative to the fixed plate 110, resulting in higher precision in battery installation and removal. Furthermore, along the second horizontal direction D2, the driving member 150 is arranged between the two scissor forks 130, making the drive distribution of the driving member 150 on the lifting plate 120 more balanced, thereby further improving the lifting precision of the lifting plate 120.

[0030] In some specific embodiments of this utility model, refer to Figure 1 and Figure 3 The lifting device 100 includes two transmission components 140 and a synchronous connecting member 170. The synchronous connecting member 170 is disposed between the two transmission components 140 and connected to the track plates 141 of the two transmission components 140. The synchronous connecting member 170 enables the two track plates 141 to be driven synchronously, thereby enabling the lifting plate 120 to maintain balance during lifting and lowering movements, making the lifting of the lifting plate 120 more stable.

[0031] In some specific embodiments of this utility model, refer to Figure 1 and Figure 3The lifting device 100 also includes two tracks 180, both of which are mounted on the fixed plate 110 and extend along the first horizontal direction D1. The two tracks 180 are also arranged along the second horizontal direction D2 on both sides of the driving member 150. The synchronous connecting member 170 has two sliders 171 at each end along the second horizontal direction D2, which is perpendicular to the first horizontal direction D1. The two sliders 171 are respectively engaged with the two tracks 180, allowing the sliders 171 to be movably connected to the two tracks 180 along the first horizontal direction D1. This allows the synchronous connecting member 170 to be movably mounted relative to the fixed plate 110 along the first horizontal direction D1, and also makes the two track plates 141 more stable when moving with the synchronous connecting member 170. Because the sliders 171 and the tracks 180 are close to the track plates 141 at one end of the synchronous connecting member 170, the two track plates 141 are less susceptible to deformation of the synchronous connecting member 170, preventing deviations in their movement.

[0032] In some specific embodiments of this utility model, refer to Figure 1 and Figure 3 The track plate 141 has limit grooves 144 on both sides of its sidewalls. The end of the synchronous connecting member 170 extends into the limit grooves 144 and is fixedly connected to the track plate 141 by two fasteners 160. The arrangement of the track plate 141 and the synchronous connecting member 170 limits their movement along the height direction D3, making it less likely for them to deviate. This facilitates the positioning and installation of the track plate 141 and the synchronous connecting member 170 and enhances the connection stability between them, making the connection less prone to deformation. This, in turn, improves the lifting accuracy of the lifting plate 120.

[0033] In some specific embodiments of this utility model, refer to Figures 1 to 3The driving component 150 includes a driving block 151, a lead screw 152, and a motor 153. The driving block 151 is arranged between two sliders 171 along the second horizontal direction D2 and connected to the bottom of the synchronous connecting component 170. The lead screw 152 is parallel to the first horizontal direction D1 and rotatably connected to the top surface of the fixed plate 110 through a bearing 154. The lead screw 152 passes through the driving block 151 and is threadedly engaged with the driving block 151. The motor 153 is disposed on the top surface of the fixed plate 110, and the output end of the motor 153 is connected to the end of the lead screw 152. When the motor 153 is started, the output shaft of the motor 153 drives the lead screw 152 to rotate, causing the sliders 171 to move along the first horizontal direction D1, thereby driving the synchronous connecting component 170 and the track plate 141 to be raised and lowered. Due to the configuration of the transmission assembly 140, the driving force requirement for the drive component 150 (e.g., the torque of the motor 153) is not high, thereby reducing the manufacturing cost of the lifting device 100. When the slider 171 is in the initial position, the transmission wheel 142 is located at the bottom end of the inclined surface 143, and the lifting plate 120 is in the lowest position. As the motor 153 continues to operate, the slider 171 moves from the initial position to the end position, and the transmission wheel 142 moves along the inclined surface 143 to the top end of the inclined surface 143, thereby driving the lifting plate 120 to move along the height direction D3 to the highest position, thus lifting the battery.

[0034] Optionally, a first limit block is provided at both ends of the track 180 to limit the travel of the slider 171 and prevent the slider 171 from disengaging from the track 180. When the motor 153 fails, the weight of the battery and the lifting plate 120 will drive the track plate 141 to move, eventually causing the slider 171 to disengage from the track 180. Therefore, the track 180 also helps to prevent the drive wheel 142 from disengaging from the track plate 141.

[0035] Optionally, a second limiting block is provided at both ends of the inclined surface 143 of the track plate 141, which can limit the travel of the transmission wheel 142 on the inclined surface 143. This helps to prevent the transmission wheel 142 from moving to the top of the inclined surface 143 and detaching from the track plate 141, thus preventing a safety accident. It also helps to prevent a safety accident caused by the weight of the battery and the lifting plate 120 causing the lifting device 100 to go out of control when the motor 153 fails, thereby improving the operational safety of the lifting device 100.

[0036] In some specific embodiments of this utility model, refer to Figure 1The angle between the inclined surface 143 and the horizontal plane containing the first horizontal direction D1 is between 15° and 45°. By setting the inclined surface 143, the driving force transmitted by the driving component 150 to the track plate 141 along the first horizontal direction D1 via the slider 171 and the synchronous connecting component 170 is increased. This makes the driving force ultimately transmitted by the driving component 150 to the lifting plate 120 more stable and reduces the driving force requirement of the lifting device 100 on the driving component 150. Furthermore, the inclined surface 143 prevents the height and dimensions along the first horizontal direction D1 of the lifting device 100 from becoming excessive. Preferably, the angle between the inclined surface 143 and the horizontal plane containing the first horizontal direction D1 can be 20° or 30°, thereby ensuring that the height and dimensions along the first horizontal direction D1 of the lifting device 100 are within a reasonable range and that the driving force requirement of the lifting device 100 on the driving component 150 is reasonable.

[0037] As an alternative, depending on the actual parameters such as the size and weight of the battery to be lifted, the angle between the inclined surface 143 of the track plate 141 and the horizontal plane where the first horizontal direction D1 is located can also be between 0° and 15° (excluding 0°) to ensure stable lifting of the battery. All of these should be within the protection scope of this utility model.

[0038] In some specific embodiments of this utility model, refer to Figure 1 A connecting plate 123 is provided on the bottom surface of the lifting plate 120, and the transmission wheel 142 is rotatably connected to the connecting plate 123, so that the transmission wheel 142 can rotate relative to the lifting plate 120, reducing the friction between the lifting plate 120 and the transmission component 140, making the transmission of the lifting device 100 smoother.

[0039] In some specific embodiments of this utility model, refer to Figure 4 The lifting plate 120 is provided with a maintenance weight reduction groove 122. At least a portion of the maintenance weight reduction groove 122 overlaps with the projection of at least one of the scissor fork 130, drive component 150, and transmission assembly 140 along the height direction D3, thereby facilitating the maintenance or disassembly of at least one of the scissor fork 130, drive component 150, and transmission assembly 140 from the top of the lifting device 100. In addition, the maintenance weight reduction groove 122 also reduces the weight of the lifting plate 120, which is beneficial to the lightweight design of the lifting device 100.

[0040] In some specific embodiments of this utility model, refer to Figure 4The lifting plate 120 is provided with three maintenance weight reduction slots 122. The three maintenance weight reduction slots 122 are arranged at intervals along the first horizontal direction D1, so as to be arranged above the motor 153, the lead screw 152 and the synchronous connection component 170, thereby facilitating the staff to inspect or disassemble the drive component 150, which is most prone to failure.

[0041] In some specific embodiments of this utility model, refer to Figure 1 and Figure 4 The lifting plate 120 is also provided with a battery support block 121, which is used to fit the battery. This can reduce the wear between the battery and the lifting plate 120, and can also ensure the accuracy of the lifting device 100 in installing and removing the battery by matching the battery support block 121 with the corresponding battery structure (such as a groove).

[0042] This utility model also provides a battery swapping station, including the aforementioned battery lifting device 100. The battery swapping station of this utility model reduces the requirements of the lifting device 100 on the drive component 150, making the drive of the lifting device 100 more stable and reducing the manufacturing cost of the lifting device 100 and the battery swapping station. At the same time, the height of the lifting device 100 is not excessive, thus not increasing the vehicle's lifting height and affecting the battery swapping experience for the driver.
