Description

Battery swap platforms and stations CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to Chinese patent application CN202420562114.4 filed on March 18, 2024, with the invention name “Battery Swap Platform and Battery Swap Station”. The entire contents of the above Chinese patent application are incorporated into this application by reference. Technical Field

[0002] The present invention relates to the field of battery charging and battery swapping technology, and in particular to a battery swapping platform and a battery swapping station. Background Art

[0003] Battery swapping, a key refueling method for new energy vehicles, is highly favored by users for its advantages of quick turnaround, excellent user experience, and minimal impact on the battery. Battery swapping typically takes place at a battery swapping station. During the process, the vehicle to be swapped is parked on a swapping platform, and a battery swapping robot moves back and forth between the battery compartment and the vehicle below, removing a depleted battery and installing a fully charged one.

[0004] Since the space between the vehicle to be battery-swapped and the battery-swapped platform is relatively cramped, the battery-swapped robot usually cannot enter directly. Therefore, there are usually the following solutions on the market: one is to set up a lifting mechanism on the battery-swapped platform to lift the vehicle to be battery-swapped to form a space for the battery-swapped robot to enter and exit; the other is to raise the battery-swapped platform and form a space for the battery-swapped robot to enter and exit under the battery-swapped platform; and there is also a channel for the battery-swapped robot to move downward under the battery-swapped platform. Compared with the other two solutions, the solution of setting up a lifting mechanism has relatively low requirements for the site selection, infrastructure, and transportation of the battery-swapped station, and is more suitable for promotion and use. However, this solution inevitably has some defects: for example, when the lifting mechanism lifts the vehicle to be battery-swapped, there will be safety hazards in the space under the vehicle to be battery-swapped.

[0052] In the following description, the length direction of the battery swap platform is first defined as the direction in which the vehicle enters and exits the battery swap platform, that is, the length direction of the vehicle body when parked on the battery swap platform. The width direction of the battery swap platform is the direction in the horizontal plane perpendicular to the length direction, that is, the width direction of the vehicle body after being parked on the battery swap platform.

[0053] It should also be noted that in order to describe the present application more clearly, some structures of the battery swap station are hidden in the accompanying drawings. The hidden structure does not affect the understanding of the technical solution of the present application.

[0054] First, referring to Figures 1 to 3, the battery swap platform of the present application is described.

[0055] As shown in Figures 1 to 3, in order to solve the problem of potential safety hazards under the vehicle after the vehicle to be replaced with a battery is lifted, the present application provides a battery replacement platform, including a platform body 1, a first lifting part 2 and a second lifting part 3 provided on the platform body 1, and a first telescopic protective cover 4. The first lifting part 2 is configured to be able to lift one of the front and rear parts of the vehicle to be replaced with a battery, and the second lifting part 3 is configured to be able to lift the other of the front and rear parts of the vehicle to be replaced with a battery. A first receiving groove 11 is formed on the platform body 1, and the first telescopic protective cover 4 is longitudinally telescopically provided in the first receiving groove 11, and the first telescopic protective cover 4 is connected to the first lifting part 2. The first telescopic protective cover 4 is configured to extend as the first lifting part 2 lifts when the vehicle to be replaced with a battery is lifted, and to shield the space below the vehicle to be replaced with a battery, and to retract as the first lifting part 2 lowers when the vehicle to be replaced with a battery is lowered.

[0056] The front and rear parts of the vehicle to be replaced are divided according to the length of the vehicle to be replaced. The front part refers to the vehicle body located on the front side of the length of the vehicle to be replaced, and the rear part refers to the vehicle body located on the rear side of the length of the vehicle to be replaced. For example, the front part of the vehicle to be replaced can be the front wheel position, the A-pillar / the sill beam below the front door, etc.; the rear part of the vehicle to be replaced can be the rear wheel position, the C-pillar / the sill beam below the rear door, etc.

[0057] For example, during the battery swapping process, the vehicle to be swapped is parked onto the battery swapping platform. The first lifting part 2 and the second lifting part 3 lift the vehicle by lifting the two front wheels and the two rear wheels, so that sufficient space for battery swapping is formed under the vehicle. During the lifting process, the first telescopic shield 4 extends as the first lifting part 2 lifts up, so that the space between the front wheels and the battery swapping platform is blocked. After the battery swapping is completed, the first lifting part 2 and the second lifting part 3 drive the vehicle to fall. During the falling process, the first telescopic shield 4 retracts as the first lifting part 2 descends, and is finally retracted into the first receiving slot 11.

[0058] The technical solution of this application, by providing a first telescopic shield 4, can shield the space below the vehicle to be replaced after it is lifted, preventing people or pets from entering the area below the vehicle to be replaced, thereby improving the safety of the battery replacement process. The provision of the first receiving groove 11 allows the first telescopic shield 4 to be embedded in the platform body 1, preventing the first telescopic shield 4 from protruding from the platform body 1 and affecting parking.

[0059] A possible implementation of the battery swap platform of the present application is introduced below in conjunction with Figures 1 to 6.

[0060] 1 to 6 , in one possible implementation, the battery swap platform includes a platform body 1 , a first lifting portion 2 , a second lifting portion 3 , a first telescopic cover 4 , and a second telescopic cover 5 .

[0061] The platform body 1 is a frame structure formed by connecting metal square tubes. The platform body 1 is provided with a first receiving groove 11 and a second receiving groove 12. The first receiving groove 11 and the second receiving groove 12 are located at both ends of the platform body 1 along the length direction of the platform body 1. The first receiving groove 11 is located at the front end of the platform body 1, which corresponds to the entrance of the battery swap station, and the second receiving groove 12 is located at the rear end of the platform body 1, which corresponds to the rear wall of the battery swap station. The first receiving groove 11 and the second receiving groove 12 can be formed by the frame structure itself, such as being formed by being enclosed between the frame structure and the metal base plate, or by being enclosed between the frame structure and the ground of the battery swap station. The first lifting part 2 and the second lifting part 3 are arranged at both ends of the platform body 1 along the length direction of the battery swap platform, wherein the first lifting part 2 is arranged at the front end of the platform body 1 and partially arranged in the first receiving groove 11, and the second lifting part 3 is arranged at the rear end of the platform body 1 and partially arranged in the second receiving groove 12.

[0062] 1 and 3 , the first lifting portion 2 includes a first driving device 21 and a first positioning device 22. The first driving device 21 is connected to the first positioning device 22. The first positioning device 22 is arranged in the first accommodating groove 11. The first positioning device 22 is arranged to be able to position the two front wheels of the battery-swap vehicle. The first driving device 21 is arranged to be able to drive the first positioning device 22 to rise and fall. Specifically, the first driving device 21 includes two first driving mechanisms. The two first driving mechanisms are arranged on both sides of the platform body 1 along the width direction, and the two first driving mechanisms are respectively connected to the two ends of the first positioning device 22. The specific structural form of the first driving mechanism is not limited in this application. As long as the mechanism can realize the lifting and lowering of the first positioning device 22, it can be used as the first driving mechanism. For example, the first driving mechanism can adopt a combination of a motor and a gear transmission chain, a motor and a screw nut, or a linear driving mechanism such as a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0063] 3 and 4 , the first positioning device 22 includes a first frame 221 and a first roller assembly 222 disposed within the first frame 221. The first frame 221 is embedded within the first receiving groove 11. In this application, the first roller assembly 222 is a V-shaped roller assembly disposed within the first frame 221. Two first drive mechanisms are connected to both ends of the first frame 221. A first flange 2211 is formed on the side wall of the first frame 221 away from the platform body 1. A plurality of first connecting ribs 2212 are disposed between the first flange 2211 and the side wall forming the first flange 2211. The first telescopic shield 4 is connected to the first connecting ribs 2212.

[0064] 1 and 2 , the second lifting portion 3 includes a second driving device 31 and a second positioning device 32. The second driving device 31 is connected to the second positioning device 32. The second positioning device 32 is arranged in the second accommodating groove 12. The second positioning device 32 is arranged to be able to position the two rear wheels of the battery-swap vehicle. The second driving device 31 is arranged to be able to drive the second positioning device 32 to rise and fall. Specifically, the second driving device 31 includes two second driving mechanisms. The two second driving mechanisms are arranged on both sides of the platform body 1 along the width direction, and the two second driving mechanisms are respectively connected to the two ends of the second positioning device 32. The specific structural form of the second driving mechanism is not limited in this application. As long as the mechanism can realize the lifting and lowering of the second positioning device 32, it can be used as the second driving mechanism. For example, the second driving mechanism can adopt a combination of a motor and a gear transmission chain, a motor and a screw nut, or a linear driving mechanism such as a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0065] The second positioning device 32 includes a second frame 321 and a second roller assembly 322 disposed within the second frame 321. The second frame 321 is embedded within the second receiving groove 12. The second roller assembly 322 is an I-shaped roller assembly disposed within the second frame 321. The two second drive mechanisms are respectively connected to the ends of the second frame 321. A second flange is formed on the side wall of the second frame 321 away from the platform body 1. A plurality of second connecting ribs are disposed between the second flange and the side wall forming the second flange. The second telescopic shield 5 is connected to the second connecting ribs.

[0066] The above-mentioned setting method connects the first telescopic shield 4 to the first connecting rib 2212 of the first positioning device 22 away from the platform body 1, and connects the second telescopic shield 5 to the second connecting rib of the second positioning device 32 away from the platform body 1, which can shield the space under the vehicle to the greatest extent and reduce safety hazards.

[0067] 4 to 6 , the first telescopic shield 4 includes a plurality of first shielding members 41 , with adjacent first shielding members 41 slidingly nested with each other. The innermost or outermost first shielding member 41 of the plurality of first shielding members 41 is connected to the first lifting portion 2 . Specifically, in the present application, the first telescopic shield 4 includes four first shielding members 41 , which are sequentially slidably nested from the inside out. The innermost first shielding member 41 is fixedly connected to the bottom of the first accommodating groove 11 , and the outermost first shielding member 41 is fixedly connected to the first connecting rib 2212 . Each first shielding member 41 includes a first plate 411 and two first inner bends 412 formed by bending the two lateral ends of the first plate 411 toward the same side. In the present application, the first inner bends 412 are C-shaped bend structures. The first inner bends 412 of the inner first shielding member 41 of the two adjacent first shielding members 41 slide and nest within the first inner bends 412 of the outer first shielding member 41. Furthermore, of the two adjacent first shielding members 41, the outer first shielding member 41 is provided with a first limiting structure 413, and the inner first shielding member 41 is provided with a second limiting structure 421. When one of the two adjacent first shielding members 41 slides away from the other, the first limiting structure 413 can abut against the second limiting structure 421, thereby allowing the two first shielding members 41 to slide together. In one possible embodiment, the first limiting structure 413 is an inner flange formed by bending the lower side of the first inner bend 412 of the first shielding member 41 located on the outside toward the inside of the first inner bend 412, and the second limiting structure 421 is an outer edge of the first reinforcing plate 42 disposed on the top side of the first shielding member 41 located on the inside, extending beyond the first inner bend 412 of the first shielding member 41. The inner flange is formed at the bottom of the side where the first inner bend 412 meets the first plate 411, and the outer edge is formed by the first reinforcing plate 42 extending outward along the length of the first plate 411.

[0068] 5 , the first telescopic shield 4 further includes a first top connecting plate 43 and a first bottom connecting plate 44. The first shielding member 41 (the outermost first shielding member 41 in this application) that extends from the top of the plurality of first shielding members 41 is fixedly connected to the first top connecting plate 43. The first top connecting plate 43 has multiple through-holes, and the bottom surface of the first connecting rib 2212 correspondingly has multiple threaded holes. Screws pass through the through-holes and connect with the threaded holes, thereby connecting the first top connecting plate 43 to the first connecting rib 2212. The first shielding member 41 (the innermost first shielding member 41 in this application) that extends from the bottom of the plurality of first shielding members 41 is connected to the first bottom connecting plate 44. The first bottom connecting plate 44 has a through-hole, and the bottom of the first accommodating slot 11 has a threaded hole. Screws pass through the through-holes and connect with the threaded holes, thereby connecting the first bottom connecting plate 44 to the bottom of the first accommodating slot 11.

[0069] Referring back to Figure 2 , three first telescopic shields 4 are provided in the present application. The three first telescopic shields 4 are arranged side by side along the width direction of the battery exchange platform, and the three first telescopic shields 4 are all connected to the first connecting rib 2212 provided on the first frame 221 .

[0070] In this way, when the first driving device 21 lifts the first positioning device 22, the three first telescopic shields 4 are extended synchronously with the rise of the first positioning device 22. During the extension process, the outermost first shielding member 41 starts to extend. When the inner flange on the outermost first shielding member 41 abuts against the outer edge of the adjacent inner first shielding member 41, the outermost first shielding member 41 drives the adjacent inner first shielding member 41 to rise, and so on, until all the first shielding members 41 are extended.

[0071] The arrangement of multiple first shielding members 41 can reduce the space occupied by the first telescopic shield 4 on the battery exchange platform. The two adjacent first shielding members 41 are slidably nested and connected to each other, which can simplify the structure and ensure sliding stability. The arrangement of the first inner bend 412 is conducive to reducing the manufacturing cost of the first shielding member 41. By setting the first limiting structure 413 and the second limiting structure 421, effective limiting between adjacent first shielding members 41 can be achieved during the sliding process, thereby improving sliding stability. By setting multiple first telescopic shields 4, it is conducive to reducing the difficulty of manufacturing and assembling the first telescopic shield 4.

[0072] The second telescopic shield 5 is set up in a similar manner to the first telescopic shield 4, so a brief description is given below. The second telescopic shield 5 is set up in the second accommodating groove 12 in a longitudinally telescopic manner, and the second telescopic shield 5 is connected to the second lifting part 3. The second telescopic shield 5 is configured to extend as the second lifting part 3 lifts up when the vehicle to be replaced is lifted, and to block the space below the vehicle to be replaced, and to retract as the second lifting part 3 lowers when the vehicle to be replaced is lowered. Specifically, the second telescopic shield 5 includes a plurality of second shielding members, and two adjacent second shielding members are slidably nested and connected to each other, and the second shielding member at the innermost or outermost side of the plurality of second shielding members is connected to the second lifting part 3. In the present application, the second telescopic shield 5 includes four second shielding members, and the four second shielding members are slidably nested and connected in sequence from the inside to the outside. The second shielding member at the innermost side is fixedly connected to the bottom of the second accommodating groove 12, and the second shielding member at the outermost side is fixedly connected to the second connecting rib. Each first shielding member 41 includes a second plate body and two second inner bends formed by bending the lateral ends of the second plate body toward the same side. The second inner bends in this application are C-shaped bend structures. The second inner bend of the inner second shielding member of the two adjacent second shielding members slides and nests within the second inner bend of the outer second shielding member. Furthermore, the outer second shielding member of the two adjacent second shielding members is provided with a third limiting structure, and the inner second shielding member is provided with a fourth limiting structure. When one of the two adjacent second shielding members slides away from the other, the third limiting structure can abut against the fourth limiting structure, thereby allowing the two second shielding members to slide together. In one possible embodiment, the third limiting structure is an inner folded edge of the second inner bend of the outer second shielding member, which is bent toward the inside of the second inner bend. The fourth limiting structure is a second reinforcing plate provided on the top side of the inner second shielding member, which extends outward from the outer edge of the second inner bend of the second shielding member. The inner flange is formed at the bottom of the side surface where the second inner bend meets the second plate body, and the outer edge is formed by the second reinforcing plate extending outward along the length direction of the second plate body.

[0073] The second telescopic shield 5 also includes a second top connecting plate and a second bottom connecting plate. The second shielding member (the outermost second shielding member) located at the top of the plurality of second shielding members after extending is connected to the second top connecting plate. The second top connecting plate has multiple through holes, and the bottom surface of the second connecting rib has multiple threaded holes. Screws pass through the through holes and connect with the threaded holes, thereby connecting the second top connecting plate to the second connecting rib. The second shielding member (the innermost first shielding member 41) located at the bottom of the plurality of second shielding members after extending is connected to the second bottom connecting plate. The second bottom connecting plate has a through hole, and the bottom of the second accommodating slot 12 has a threaded hole. Screws pass through the through holes and connect with the threaded holes, thereby connecting the second bottom connecting plate to the bottom of the second accommodating slot 12.

[0074] Referring to FIG. 3 , three second telescopic shields 5 are provided. The three second telescopic shields 5 are arranged side by side along the width direction of the battery exchange platform. The three second telescopic shields 5 are all connected to the second connecting ribs provided on the second frame 321 .

[0075] In this way, when the second driving device 31 lifts the second positioning device 32, the three second telescopic shields 5 are extended synchronously with the rise of the second positioning device 32. During the extension process, the outermost second shielding member starts to extend. When the inner flange on the outermost second shielding member abuts the outer edge of the adjacent inner second shielding member, the outermost second shielding member drives the second shielding member adjacent to it to rise, and so on, until all the second shielding members are extended.

[0076] By providing a second telescopic shield 5, after the vehicle to be replaced with a battery is lifted, the second telescopic shield 5 can be extended from the rear of the vehicle to block the space under the vehicle to be replaced with a battery, thereby preventing people or pets from entering from the rear of the vehicle under the vehicle to be replaced with a battery, thereby improving the safety of the battery replacement process. The arrangement of multiple second shielding members can reduce the space occupied by the second telescopic shield 5 on the battery replacement platform, and the sliding and nesting connection between two adjacent second shielding members can simplify the structure and ensure sliding stability. The arrangement of the second inner bend is conducive to reducing the manufacturing cost of the second shielding member. By providing a third limiting structure and a fourth limiting structure, effective limiting between adjacent second shielding members can be achieved during the sliding process, thereby improving sliding stability. The arrangement of multiple second telescopic shields 5 is conducive to reducing the difficulty of manufacturing and assembling the second telescopic shields 5.

[0077] It should be noted that the above preferred embodiments are only used to illustrate the principles of this application and are not intended to limit the scope of protection of this application. Without departing from the principles of this application, those skilled in the art may adjust the above settings so that this application can be applied to more specific application scenarios.

[0078] For example, in an alternative embodiment, although the above embodiment is described in conjunction with the battery swap platform including the first telescopic shield 4 and the second telescopic shield 5, this is merely exemplary, and those skilled in the art will understand that when one end of the battery swap platform is closed, it is only necessary to set a telescopic shield to block the space under the vehicle on the other side, which can greatly improve the safety of the battery swap process. For example, if the vehicle enters the battery swap platform by parking, then the front of the vehicle is facing the entrance of the battery swap platform, and at this time, it is only necessary to set the first telescopic shield 4 under the first lifting portion 2. If the vehicle enters the battery swap platform in the forward direction, then the rear of the vehicle is facing the entrance of the battery swap platform, and the first lifting portion 2 is used to lift the rear of the vehicle, and at this time, it is only necessary to set the first telescopic shield 4 under the first lifting portion 2.

[0079] For example, while the above embodiment describes the first lifting portion 2 as including the first drive device 21 and the first positioning device 22, the specific structure of the first lifting portion 2 is not exclusive. In other embodiments, the first lifting portion 2 can also be configured to lift the vehicle chassis, such as by driving a lifting plate with the first drive device 21 to lift the chassis. In this case, the first telescopic cover 4 can simply be connected to the lifting plate. Similarly, the second lifting portion 3 can be replaced in a similar manner and will not be further described.

[0080] For example, while the first telescopic shield 4 includes four first shielding members 41 in the above-described embodiment, the specific configuration of the first telescopic shield 4 is not unique. In other embodiments, if the first accommodating groove 11 is sufficiently deep, only one first shielding member 41 may be provided, or the number of first shielding members 41 may be set to two, three, or more. For another example, the connection method between the multiple first shielding members 41 in the first telescopic shield 4 is not unique, as long as the first telescopic shield 4 is configured to be telescopic after configuration. For example, the multiple first shielding members 41 may be connected by means of slide rails, slide rail slots, etc., and the first shielding members 41 may not have an inner bend in this case, and may be in the form of a plate. For another example, in addition to achieving a sliding nested connection between adjacent first shielding members 41 using the first inner bend 412, the first shielding members 41 may also be configured as rectangular barrels and nested together. For another example, the fact that one of the two adjacent first shielding members 41 is provided with a first limiting structure 413 and the other with a second limiting structure 421 is merely exemplary. The first limiting structure 413 and the second limiting structure 421 are not required. In other embodiments, the first shielding member 41 can be provided as a whole with a trapezoidal structure having unequal widths at the top and bottom to achieve mutual limitation. For another example, the location or form of the first limiting structure 413 and the second limiting structure 421 can also be adjusted, such as the first limiting structure 413 being provided in the middle or lower middle portion, and the second limiting structure 421 being provided in the middle or upper middle portion. The first limiting member can also be a protrusion formed from the outside to the inside, and the second limiting member can also be a protrusion formed from the inside to the outside, or an outer flange formed at the top. The replacement method of the second telescopic shield 5 is similar to this and will not be repeated here.

[0081] For another example, the provision of the first top connecting plate 43 and the first bottom connecting plate 44 is merely exemplary; those skilled in the art may choose whether to provide both based on specific needs. For example, those skilled in the art may selectively omit at least one of the two. Without the first top connecting plate 43, the first plate 411 of the outermost first shielding member 41 may be connected to the sidewall of the first frame 221. Without the first bottom connecting plate 44, the innermost first shielding member 41 may be stabilized by its own weight. The replacement of the second top connecting plate and the second bottom connecting plate is similar and will not be further described.

[0082] For example, the first telescopic shield 4 is described in the above embodiment as being connected to the first connecting rib 2212. However, the specific connection position of the first telescopic shield 4 is not fixed and can be adjusted by those skilled in the art without departing from the principles of the present application, as long as the first telescopic shield 4 is connected to the first lifting portion 2 and can expand and contract with the movement of the first lifting portion 2. For example, the first telescopic shield 4 can also be fixedly connected to the first flange 2211, or any side wall or bottom of the first frame 221. The replacement method of the second telescopic shield 5 is similar to that of the first telescopic shield 4 and will not be further described.

[0083] For another example, in another alternative embodiment, the specific number of the first telescopic shields 4 is not limited in this application. The above embodiment is described using three as an example. However, in other embodiments, those skilled in the art may adjust the number, such as providing only one, two, or four. The number of the second telescopic shields 5 can also be adjusted in the same manner as described above, and will not be further described here.

[0084] For example, in another alternative embodiment, the specific structures of the first positioning device 22 and the second positioning device 32 are not fixed and can be adjusted by those skilled in the art, as long as the first positioning device 22 and the second positioning device 32 can achieve vehicle positioning. For example, the V-shaped roller assembly of the first positioning device 22 and the I-shaped roller assembly of the second positioning device 32 can be interchangeable.

[0085] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-functional manner to combine new implementations to suit more specific application scenarios.

[0086] The present application also provides a battery swap station, which includes a battery swap platform according to any one of the above technical solutions.

[0087] The battery swap station of the present application, by arranging the first telescopic shield 4 and the second telescopic shield 5 on the battery swap platform, can, after the vehicle to be battery swapped is lifted, use the follow-up extension of the first telescopic shield 4 and the second telescopic shield 5 to shield the space under the vehicle to be battery swapped from both the head and tail directions of the vehicle, thereby preventing people or pets from entering under the vehicle to be battery swapped and improving the safety of the battery swap process.

[0088] The following introduces a possible battery replacement process of the battery replacement station of this application.

[0089] In a possible battery swapping process, the vehicle to be battery swapped enters the battery swapping platform by parking. After parking, the rear wheels of the vehicle are supported on the I-type roller group, and the front wheels are stuck in the V-type roller group. Subsequently, the first drive device 21 and the second drive device 31 are operated simultaneously, driving the first positioning device 22 and the second positioning device 32 to rise, thereby lifting the vehicle. During the ascent of the first positioning device 22 and the second positioning device 32, the first telescopic protective cover 4 and the second telescopic protective cover 5 are extended synchronously to block the space under the front and rear of the vehicle to prevent small animals or unrelated personnel from entering the space under the vehicle. When the battery swapping of the vehicle is completed, the first drive device 21 and the second drive device 31 are operated again, driving the first positioning device 22 and the second positioning device 32 to descend, thereby dropping the vehicle. During the falling process of the vehicle, the first telescopic protective cover 4 and the second telescopic protective cover 5 are retracted synchronously until the vehicle falls to the platform body 1, and the first telescopic protective cover 4 and the second telescopic protective cover 5 are hidden in the first receiving groove 11 and the second receiving groove 12 respectively.

[0090] Those skilled in the art will appreciate that although some embodiments described herein include certain features included in other embodiments but not other features, combinations of features from different embodiments are intended to be within the scope of this application and to form different embodiments. For example, in the claims of this application, any of the claimed embodiments may be used in any combination.

[0091] Thus far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present application.
