Description

Technical Field

[0001] The utility model relates to the technical field of charging and battery replacement, and in particular to a battery replacement platform and a battery replacement station. Background Art

[0002] As an important way to replenish energy for new energy vehicles, battery swapping is popular among users for its advantages of short time, good experience and little impact on the battery. Battery swapping is usually carried out in a battery swapping station. During the battery swapping process, the vehicle to be swapped is parked on the battery swapping platform, and the battery swapping robot moves back and forth between the battery compartment and the bottom of the vehicle to be swapped, realizing the removal of the depleted battery and the installation of the fully charged battery.

[0003] Since the space between the vehicle to be replaced and the battery replacement platform is relatively cramped, the battery replacement 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 replacement platform to lift the vehicle to be replaced to form a space for the battery replacement robot to enter and exit; the other is to raise the battery replacement platform and form a space for the battery replacement robot to enter and exit under the battery replacement platform; and there is also a way to dig a channel for the battery replacement robot to move downward under the battery replacement 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 replacement 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 replaced, there will be safety hazards in the space under the vehicle to be replaced.

[0073] 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 the vehicle is parked on the battery swap platform. The width direction of the battery swap platform is the direction perpendicular to the length direction in the horizontal plane, that is, the width direction of the vehicle body after the vehicle is parked on the battery swap platform.

[0074] 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, and the hidden structure does not affect the understanding of the technical solution of the present application.

[0075] First refer to Figures 1 to 3 , describe the battery swap platform of this application.

[0076] like Figures 1 to 3 As shown, in order to solve the problem of potential safety hazards under the vehicle after the vehicle to be replaced with batteries 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 arranged 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 batteries, 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 batteries. A first accommodating groove 11 is formed on the platform body 1, and the first telescopic protective cover 4 is longitudinally telescopically arranged in the first accommodating 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 with the lifting action of the first lifting part 2 when the vehicle to be replaced with batteries is lifted, and the space below the vehicle to be replaced with batteries is blocked, and retract with the lowering action of the first lifting part 2 when the vehicle to be replaced with batteries is lowered.

[0077] 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 body located on the front side of the vehicle to be replaced in the length direction, and the rear part refers to the body located on the rear side of the vehicle to be replaced in the length direction.

During the lifting process, the first telescopic cover 4 extends out with the lifting action of the first lifting part 2, 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 cover 4 is retracted with the descending action of the first lifting part 2, and finally retracted into the first receiving groove 11.

[0079] The technical solution of the present application, by providing a first telescopic shield 4, can shield the space under the vehicle to be replaced by the follow-up extension of the first telescopic shield 4 after the vehicle to be replaced is lifted, so as to prevent people or pets from entering under the vehicle to be replaced, thereby improving the safety of the battery replacement process.

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. 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 the present application. As long as the mechanism can realize the driving of the second positioning device 32 to rise and fall, 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 lead screw nut, or a linear driving mechanism such as a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0086] The second positioning device 32 includes a second frame 321 and a second roller group 322 disposed in the second frame 321, wherein the second frame 321 is embedded in the second receiving groove 12, the second roller group 322 is an I-type roller group, the I-type roller group is disposed in the second frame 321, and the two second driving mechanisms are respectively connected to the two ends of the second frame 321.

[0087] The above-mentioned arrangement 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.

[0088] See also Figures 4 to 6The first telescopic shield 4 includes a plurality of first shielding members 41, and two adjacent first shielding members 41 are slidably nested and connected with each other, and the first shielding member 41 located at the innermost or outermost side of the plurality of first shielding members 41 is connected with the first lifting portion 2. Specifically, in the present application, the first telescopic shield 4 includes four first shielding members 41, and the four first shielding members 41 are slidably nested and connected in sequence from the inside to the outside, the first shielding member 41 located at the innermost side is fixedly connected to the bottom of the first receiving groove 11, and the first shielding member 41 located at the outermost side is fixedly connected to the first connecting rib 2212. For each first shielding member 41, it includes a first plate body 411 and two first inner bends 412 formed by bending the lateral ends of the first plate body 411 to the same side. The first inner bend 412 is a bend structure with a C-shaped cross section in the present application. The first inner bend 412 of the first shielding member 41 located at the inner side of the two adjacent first shielding members 41 is slidably nested in the first inner bend 412 of the first shielding member 41 located at the outer side. Further, among the two adjacent first shielding members 41, the first shielding member 41 located on the outside is provided with a first limiting structure 413, and the first shielding member 41 located on the inside is provided with a second limiting structure 421. When one of the two adjacent first shielding members 41 slides in a direction away from the other, the first limiting structure 413 can abut against the second limiting structure 421 and thus make the two first shielding members 41 slide together. In a possible embodiment, the first limiting structure 413 is an inner turning edge of the lower side edge of the first inner bend 412 of the first shielding member 41 located on the outside and bent 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 provided on the top side of the first shielding member 41 located on the inside, after extending out of the first inner bend 412 of the first shielding member 41. The inner turning edge is formed at the bottom of the side surface where the first inner bend 412 is connected to the first plate body 411, and the outer edge is formed by the first reinforcing plate 42 extending outward along the length direction of the first plate body 411.

[0089] See also Figure 5The first telescopic shield 4 also 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) located at the uppermost side after extending out of the plurality of first shielding members 41 is fixedly connected to the first top connecting plate 43, wherein the first top connecting plate 43 is provided with a plurality of through holes, and the bottom surface of the first connecting rib 2212 is provided with a plurality of threaded holes, and screws are connected through the through holes and the threaded holes to achieve the connection between the first top connecting plate 43 and the first connecting rib 2212. The first shielding member 41 (the innermost first shielding member 41 in this application) located at the lowermost side after extending out of the plurality of first shielding members 41 is connected to the first bottom connecting plate 44, wherein the first bottom connecting plate 44 is provided with a through hole, and the bottom of the first receiving groove 11 is provided with a threaded hole, and screws are connected through the through holes and the threaded holes to achieve the connection between the first bottom connecting plate 44 and the bottom of the first receiving groove 11.

[0090] Return to see Figure 2 In the present application, three first telescopic shields 4 are provided, and 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 ribs 2212 provided on the first frame 221.

[0091] 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 begins 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.

[0092] 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.

[0093] The second telescopic shield 5 is similar to the first telescopic shield 4 in terms of setting, so a brief description is given below. The second telescopic shield 5 is longitudinally telescopically arranged in the second receiving groove 12, and the second telescopic shield 5 is connected to the second lifting portion 3. The second telescopic shield 5 is arranged to extend along with the lifting action of the second lifting portion 3 when the vehicle to be replaced is lifted, and the space below the vehicle to be replaced is blocked, and retract along with the lowering action of the second lifting portion 3 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 portion 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 receiving 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 two lateral ends of the second plate body toward the same side. The second inner bend in the present application is a bend structure with a C-shaped cross section. The second inner bend of the second shielding member located on the inner side of the two adjacent second shielding members slides and nests in the second inner bend of the second shielding member located on the outer side. Further, in the two adjacent second shielding members, a third limiting structure is provided on the second shielding member located on the outer side, and a fourth limiting structure is provided on the second shielding member located on the inner side. When one of the two adjacent second shielding members slides in a direction away from the other, the third limiting structure can abut against the fourth limiting structure and thus make the two second shielding members slide together. In a possible embodiment, the third limiting structure is an inner folding edge of the lower side edge of the second inner bend of the second shielding member located on the outer side bent toward the inner side of the second inner bend, and the fourth limiting structure is a second reinforcing plate provided on the top side of the second shielding member located on the inner side extending out of 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 is connected to 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.

[0094] 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 uppermost side after extending out of the plurality of second shielding members is connected to the second top connecting plate, wherein the second top connecting plate is provided with a plurality of through holes, and the bottom surface of the second connecting rib is provided with a plurality of threaded holes accordingly, and screws are connected through the through holes and threaded holes to achieve connection between the second top connecting plate and the second connecting rib. The second shielding member (the innermost first shielding member 41) located at the lowermost side after extending out of the plurality of second shielding members is connected to the second bottom connecting plate, wherein the second bottom connecting plate is provided with a through hole, and the bottom of the second receiving groove 12 is provided with a threaded hole, and screws are connected through the through holes and threaded holes to achieve connection between the second bottom connecting plate and the bottom of the second receiving groove 12.

[0095] See also Figure 3 There are three second telescopic protective covers 5 , and the three second telescopic protective covers 5 are arranged side by side along the width direction of the battery exchange platform. The three second telescopic protective covers 5 are all connected to the second connecting ribs arranged on the second frame 321 .

[0096] 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 against 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.

[0097] By providing a second telescopic protective cover 5, after the vehicle to be replaced with a battery is lifted, the second telescopic protective cover 5 can be extended from the rear of the vehicle to shield the space under the vehicle to be replaced with a battery, thereby preventing people or pets from entering under the vehicle to be replaced with a battery from the rear of the vehicle, 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 protective cover 5 on the battery replacement platform. The two adjacent second shielding members are slidably nested and connected to each other, which 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. By providing multiple second telescopic protective covers 5, it is conducive to reducing the difficulty of manufacturing and assembling the second telescopic protective covers 5.

[0098] It should be noted that the above preferred implementations are only used to illustrate the principles of the present application and are not intended to limit the scope of protection of the present application. Without departing from the principles of the present application, those skilled in the art may adjust the above settings so that the present application can be applied to more specific application scenarios.

[0099] For example, in an alternative embodiment, although the above embodiment is described in conjunction with the battery swap platform including both the first telescopic shield 4 and the second telescopic shield 5, this is merely exemplary, and those skilled in the art will appreciate that when one end of the battery swap platform is closed, only one telescopic shield needs to be provided 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 a vehicle enters the battery swap platform by parking, then the front of the vehicle faces the entrance to the battery swap platform, and at this time, only the first telescopic shield 4 needs to be provided under the first lifting portion 2. If the vehicle enters the battery swap platform in the forward direction, then the rear of the vehicle faces the entrance to the battery swap platform, and the first lifting portion 2 is used to lift the rear of the vehicle, and at this time, only the first telescopic shield 4 needs to be provided under the first lifting portion 2.

[0100] For another example, although the above embodiment is described in conjunction with the first lifting portion 2 including the first driving device 21 and the first positioning device 22, the specific structural form of the first lifting portion 2 is not unique. In other embodiments, the first lifting portion 2 can also adopt a structure for lifting the chassis of the vehicle, such as the first driving device 21 drives the lifting plate to lift the chassis, and at this time, the first telescopic cover 4 is connected to the lifting plate. Similarly, the replaceable manner of the second lifting portion 3 is similar to this, and will not be repeated.

[0101] For another example, although the first telescopic shield 4 includes four first shielding members 41 in the above-mentioned embodiment, the specific setting method of the first telescopic shield 4 is not unique. In other embodiments, if the depth of the first accommodating groove 11 is sufficient, only one first shielding member 41 can be set, or the number of the first shielding members 41 can 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 set in a telescopic manner after being set. For example, multiple first shielding members 41 can also be connected by slide rail sliders, slide rail slots, etc., and the first shielding member 41 can also be not provided with an inner bend at this time, and its shape can be a plate body. For another example, in addition to being realized by the first inner bend 412 between adjacent first shielding members 41, the sliding nested connection method can also be achieved by setting the first shielding member 41 to a rectangular barrel shape and sleeved with each other. For another example, the first limiting structure 413 is set on one of the two adjacent first shielding members 41, and the second limiting structure 421 is set on the other. This is only exemplary. The first limiting structure 413 and the second limiting structure 421 are not necessary. In other embodiments, the first shielding member 41 can also be set as a trapezoidal structure with unequal widths from top to bottom to achieve mutual limitation. For another example, the setting position 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 is set in the middle or lower middle part, and the second limiting structure 421 is set in the middle or upper middle part, etc. 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 on the top, etc. The replaceable method of the second telescopic shield 5 is similar to this and will not be repeated.

[0102] For another example, the arrangement of the first top connecting plate 43 and the first bottom connecting plate 44 is only exemplary, and those skilled in the art may choose whether to arrange the two based on specific needs. For example, those skilled in the art may selectively omit at least one of the two. When the first top connecting plate 43 is not arranged, the first plate body 411 of the outermost first shielding member 41 may be connected to the side wall of the first frame 221. When the first bottom connecting plate 44 is not arranged, the position stability of the innermost first shielding member 41 may be achieved by using its own weight. The replaceable manner of the second top connecting plate and the second bottom connecting plate is similar to this, and will not be described in detail.

[0103] For another example, the first telescopic shield 4 is described in the above embodiment by combining the connection with the first connecting rib 2212 as an example, but the specific connection position of the first telescopic shield 4 is not fixed. Without departing from the principle of the present application, those skilled in the art can adjust it, as long as the first telescopic shield 4 is connected to the first lifting part 2 and can be extended and retracted with the movement of the first lifting part 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 replaceable manner of the second telescopic shield 5 is similar to that of the first telescopic shield 4, and will not be repeated.

[0104] 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 by taking three as an example, but in other embodiments, those skilled in the art can adjust it, such as setting only one, two, four, etc. The number of the second telescopic shields 5 can also be adjusted in the above manner, which will not be repeated here.

[0105] For another example, in another alternative embodiment, the specific structures of the first positioning device 22 and the second positioning device 32 are not fixed, and those skilled in the art can adjust them as long as the first positioning device 22 and the second positioning device 32 can achieve the positioning of the vehicle. For example, the V-shaped roller group of the first positioning device 22 and the I-shaped roller group of the second positioning device 32 can be interchangeable.

[0106] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-coordinated manner to combine new implementations to suit more specific application scenarios.

[0107] The present application also provides a battery swap station, which includes a battery swap platform according to any one of the above technical solutions.

[0108] The battery swap station of the present application, by arranging the first telescopic protective cover 4 and the second telescopic protective cover 5 on the battery swap platform, can shield the space under the vehicle to be replaced from both the head and the tail of the vehicle by extending the first telescopic protective cover 4 and the second telescopic protective cover 5 after the vehicle to be replaced is lifted, thereby preventing people or pets from entering under the vehicle to be replaced and improving the safety of the battery swap process.

[0109] A possible battery replacement process of the battery replacement station of the present application is introduced below.

[0110] 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 act simultaneously, driving the first positioning device 22 and the second positioning device 32 to rise, and the vehicle is thereby lifted. During the rising process of the first positioning device 22 and the second positioning device 32, the first telescopic shield 4 and the second telescopic shield 5 extend 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 act again, driving the first positioning device 22 and the second positioning device 32 to descend, and the vehicle is thereby dropped. During the falling process of the vehicle, the first telescopic shield 4 and the second telescopic shield 5 retract synchronously until the vehicle falls to the platform body 1, and the first telescopic shield 4 and the second telescopic shield 5 are respectively hidden in the first receiving groove 11 and the second receiving groove 12.

[0111] Those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present application and form different embodiments. For example, in the claims of the present application, any one of the claimed embodiments may be used in any combination.

[0112] So 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 easy for those skilled in the art to understand that the protection scope 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 can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present application.
