However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0064] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art.

[0065] It should be understood that the terminology used herein is intended only to describe particular embodiments and is not intended to limit the scope of the invention. The singular forms “a,” “an,” and “the” are also intended to include the plural forms unless the context clearly indicates otherwise.

[0066] The ordinal numbers such as "first" and "second" used in this utility model are merely identifiers and do not have any other meaning, such as a specific order. Furthermore, for example, the term "first component" does not imply the existence of a "second component," and the term "second component" does not imply the existence of a "first component." It should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "inner," "outer," and similar expressions used in this utility model are for illustrative purposes only and are not intended to be limiting.

[0067] The terms “center,” “parallel,” “perpendicular,” “aligned,” and “symmetrical” used in this invention do not have to be precise, but can include typical engineering tolerances.

[0068] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0069] See Figures 1 to 5 This utility model provides a battery rack. The battery rack includes a battery buffer rack 144 and a battery charging rack 145. Along the height direction D3 of the battery rack, the battery charging rack 145 is connected to the upper part of the battery buffer rack 144. The connection between the battery charging rack 145 and the battery buffer rack 144 can be that the battery charging rack 145 is directly connected to the battery buffer rack 144, or the battery charging rack 145 is indirectly connected to the battery buffer rack 144 through other structures. Along the width direction D2 of the battery rack, the size of the battery charging rack 145 is smaller than the size of the battery buffer rack 144. Furthermore, in a plane perpendicular to the height direction D3 of the battery rack, the orthographic projection of the battery buffer rack 144 extends onto the width direction D2 of the battery rack, and the orthographic projection of the battery charging rack 145 extends to both ends of the width direction D2 of the battery rack.

[0070] According to the embodiments of this utility model, the battery rack has a smaller width dimension than the battery buffer rack, which not only reduces the volume of the upper part of the battery rack, thus reducing the overall volume of the battery rack, but also improves the structural stability of the battery rack. When the battery rack is applied to a battery swapping station, it helps to reduce the space occupied inside the station's enclosure and creates space between the upper part of the battery rack and the inner wall of the station's enclosure suitable for wiring or pipework.

[0071] See Figure 1 and Figure 4 In some embodiments, the battery charging rack 145 includes a plurality of uprights 145f extending along the height direction of the battery rack. The battery rack also includes a plurality of connectors 146. Each connector 146 is respectively connected to the top of the battery buffer rack 144 and the respective upright 145f. This facilitates the separate manufacture of the battery buffer rack 144 and the battery charging rack 145, which can then be assembled via the connectors 146.

[0072] Alternatively, the connector 146 is welded to the top of the battery buffer rack 144 and each column 145f.

[0073] Continue reading Figure 1 and Figure 4 Furthermore, the battery rack also includes multiple reinforcing members 147. Reinforcing members 147 are connected between the upright 145f and the battery buffer rack 144. Alternatively, reinforcing members 147 are connected between the connector 146 and the battery buffer rack 144. Or, reinforcing members 147 are connected between the upright 145f, the connector 146, and the battery buffer rack 144.

[0074] In the example shown, the reinforcing member 147 is a diagonal brace structure.

[0075] See Figure 1 In some embodiments, along the length direction D1 of the battery rack, one end of the battery buffer rack 144 has a first buffer access port 144a suitable for the battery swapping robot to retrieve and place vehicle batteries. The other end of the battery buffer rack 144 has a second buffer access port 144b suitable for the palletizer to retrieve and place vehicle batteries. Both the first buffer access port 144a and the second buffer access port 144b are connected to the internal space of the battery buffer rack 144. In some application scenarios, the battery swapping station, battery rack, and palletizer are arranged sequentially along the length direction D1 of the battery rack. The battery swapping robot moves along the length direction D1 of the battery rack to transfer vehicle batteries between the battery swapping station and the battery buffer rack 144 of the battery rack. The positions of the first buffer access port 144a and the second buffer access port 144b in the battery buffer rack 144 are suitable for such application scenarios.

[0076] See Figure 1 , Figure 2 , Figure 4 as well as Figure 5 In some embodiments, the battery buffer rack 144 includes a buffer rack body 144c and multiple buffer supports 144d. The buffer supports 144d are telescopically connected to the inner periphery of the buffer rack body 144c between an extended position and a retracted position. The buffer supports 144d in the extended position support the vehicle battery. The buffer supports 144d in the retracted position avoid the vehicle battery. This facilitates the battery swapping robot entering the lower space of the battery buffer rack 144 from the first buffer pick-up / placement port 144a, and the removal and placement of the vehicle battery on the buffer supports 144d is achieved by raising and lowering the support platform. When it is necessary to remove the vehicle battery, the support platform is first raised to a position capable of supporting the vehicle battery, then the buffer supports 144d are moved to the retracted position, and finally the support platform is lowered to remove the vehicle battery. When it is necessary to place the vehicle battery, first control the buffer support 144d to move to the retracted position, then control the support platform to rise to a position higher than the buffer support 144d, then control the buffer support 144d to move to the extended position, and then control the support platform to descend, so that the vehicle battery can be placed on the upper part of the buffer support 144d.

[0077] Furthermore, multiple buffer supports 144d are respectively located on the inner periphery of both ends of the buffer frame 144c along the width direction D2 of the battery rack and on the inner periphery of the buffer frame 144c near the first buffer pick-and-place port 144a along the length direction D1 of the battery rack. This not only achieves the function of supporting the vehicle battery, but also avoids interference with the palletizer's forks during the process of the palletizer taking out and placing the vehicle battery through the second buffer pick-and-place port 144b.

[0078] Furthermore, the multiple buffer supports 144d are divided into at least two groups. Each buffer support 144d in each group is located on the same horizontal plane to form a buffer layer. The buffer supports 144d in each group are spaced apart along the height direction D3 of the battery rack. That is, the buffer layers are spaced apart along the height direction D3. By setting at least two buffer layers, more vehicle batteries can be buffered to accommodate higher-efficiency battery swapping requirements.

[0079] See Figure 2In some embodiments, the buffer support 144d is rotatably connected to the buffer rack 144c about a vertical axis AX. Here, the vertical axis AX can be understood as a vertical axis, i.e., an axis parallel to the vertical direction. The vertical axis AX can be parallel to the height direction D3. The battery buffer rack 144 also includes an extended position sensor 144e and a retracted position sensor 144f. The extended position sensor 144e is arranged corresponding to the buffer support 144d in the extended position. The extended position sensor 144e is used to detect the position of the buffer support 144d in the extended position. The retracted position sensor 144f is arranged corresponding to the buffer support 144d in the retracted position. The retracted position sensor 144f is used to detect the position of the buffer support 144d in the retracted position. By providing the extended position sensor 144e, it is convenient to sense the buffer support 144d when it moves to the extended position. By incorporating a retraction position sensor 144f, it is possible to detect when the buffer support 144d moves to the retraction position. This allows for more precise automatic control of the buffer support 144d to rotate into position.

[0080] Continue reading Figure 2 Optionally, the battery cache rack 144 further includes a cache support drive 144g and a cache support transmission 144h. The cache support drive 144g is fixed to the cache rack body 144c. The cache support drive 144g is driven to the cache support 144d via the cache support transmission 144h, so as to actuate the cache support 144d.

[0081] For example, the cache support driver 144g can be a cylinder.

[0082] See Figure 1 , Figure 4 as well as Figure 5 In some embodiments, along the length direction D1 of the battery rack, the end of the battery charging rack 145 near the second buffer access port 144b is provided with a charging access port 145a suitable for the palletizer to remove and place batteries. This facilitates the palletizer to transfer vehicle batteries between the battery charging rack 145 and the battery buffer rack 144b. Along the length direction D1 of the battery rack, the battery charging rack 145 is provided with a charging connector 143 at the end opposite to the charging access port 145a. The charging connector 143 can move along the height direction D3 of the battery rack to electrically connect to or disconnect from the vehicle battery.

[0083] Furthermore, the battery charging rack 145 also includes a drive mechanism capable of driving the charging connector 143 to move along the height direction D3.

[0084] See Figure 1 , Figures 3 to 5In some embodiments, the battery charging rack 145 includes a charging rack body 145b, charging supports 145c, and a positioning assembly 145d. There are multiple charging supports 145c. The charging supports 145c are used to support the vehicle battery. Multiple charging supports 145c are respectively connected to the inner periphery of both ends of the charging rack body 145b along the width direction D2 of the battery rack. The positioning assembly 145d includes a lateral positioning member 145d1 and a front and rear positioning member 145d2. The lateral positioning member 145d1 is connected to both ends of the charging rack body 145b along the width direction D2 of the battery rack to facilitate positioning of the vehicle battery in the width direction D2 of the battery rack. The front and rear positioning member 145d2 is connected to one end of the charging rack body 145b near the charging connector in the length direction D1 of the battery rack to facilitate positioning of the vehicle battery in the length direction D1 of the battery rack. By providing multiple charging supports 145c, the vehicle battery can be supported. By setting the lateral positioning component 145d1 and the front and rear positioning components 145d2, the horizontal position of the vehicle battery on the battery charging rack 145 can be positioned.

[0085] See Figure 1 and Figure 3 Optionally, the upper part of the lateral positioning member 145d1 is provided with a lateral guide surface. In the width direction D2 of the battery rack, the upper end of the lateral guide surface is closer to the outside of the charging rack 145b than the lower end of the lateral guide surface. The lateral guide surface facilitates the guidance of the vehicle battery as it moves from top to bottom toward the charging support member 145c.

[0086] See Figure 1 Optionally, the upper part of the front and rear positioning members 145d2 is provided with front and rear guide surfaces. In the length direction of the battery rack, the upper end of the front and rear guide surfaces is closer to the outside of the charging rack 145b than the lower end of the front and rear guide surfaces. The front and rear guide surfaces facilitate the guidance of the vehicle battery as it moves from top to bottom toward the charging support member 145c.

[0087] See Figure 1 , Figure 3 as well as Figure 5 Furthermore, the positioning assembly 145d also includes a battery positioning pin 145d3. The battery positioning pin 145d3 is connected to the inner circumferential sides of both ends of the charging frame 145b along the width direction D2 of the battery rack. The battery positioning pin 145d3 is adapted to be inserted into the positioning holes of the vehicle battery. By providing the battery positioning pin 145d3, the vehicle battery can be positioned more precisely, building upon the positioning of the vehicle battery by the lateral positioning member 145d1 and the front and rear positioning members 145d2.

[0088] See Figure 1 and Figure 5In some embodiments, the battery charging rack 145 also includes a battery positioning sensor 145e. The battery positioning sensor 145e has a movable detection head. The detection head, in its initial state, protrudes from the charging support 145c in the height direction D3 of the battery rack. The battery positioning sensor 145e is triggered when the vehicle battery is positioned on the charging support 145c and the detection head is pressed down. By providing the battery positioning sensor 145e, the vehicle battery can be sensed when it is in place and when it is positioned correctly; similarly, it can also provide feedback when the vehicle battery is not in place.

[0089] See Figure 1 Furthermore, the battery charging rack 145 includes at least two sets of charging supports 145c. The sets of charging supports 145c are spaced apart along the height direction D3 of the battery rack. Each charging support 145c in each set is located in the same horizontal plane to form a charging layer 142. Each charging layer 142 is provided with two battery positioning sensors 145e. The two battery positioning sensors 145e are located at both ends of the charging rack body 145b along the width direction D2 of the battery rack. The two battery positioning sensors 145e are also located at both ends of the charging rack body 145b along the length direction D1 of the battery rack. That is, the two battery positioning sensors 145e of each charging layer 142 are arranged spaced apart in a direction inclined to the length direction D1, or the two battery positioning sensors 145e are arranged diagonally opposite each other. This allows for accurate detection of whether the vehicle battery is in place with fewer battery positioning sensors 145e in each charging layer 142, while also helping to simplify the structure of the battery charging rack 145 and reduce costs.

[0090] See Figure 1 , Figure 4 as well as Figure 5 In some embodiments, the battery rack further includes a top connector 148a and a bottom connector 148b. The top connector 148a is located at the top of the battery charging rack 145. The top connector 148a is adapted to connect to the top of the battery swapping station housing. The bottom connector 148b is located at the bottom of the battery buffer rack 144. The bottom connector 148b is adapted to connect to the bottom of the battery swapping station housing.

[0091] Continue reading Figure 1 , Figure 4 as well as Figure 5 In addition, the battery rack also includes a cable bridge 149. The cable bridge 149 is located at the end of the battery rack where the charging connector 143 is located. The cable bridge 149 is suitable as a fixing bracket for electrical cables, etc.

[0092] An embodiment of this utility model also provides a battery swapping station. The battery swapping station includes a housing and the aforementioned battery rack. The battery rack is disposed inside the housing. The length direction D1 of the battery rack is aligned with the length direction of the housing. Along the width direction D2 of the battery rack, the battery charging rack 145 is spaced apart from the inner wall of the housing to form a clearance space. The clearance space is at least suitable for laying cables and / or pipes.

[0093] According to the embodiments of the present invention, the battery swapping station, by applying the above-mentioned battery rack, can form a clearance space between the battery charging rack and the inner wall of the box, which is suitable for laying cables and / or pipes, thereby improving the utilization rate of the internal space of the box, and thus helping to reduce the size of the box in the width direction or adapt to application scenarios where the size of the box in the width direction is small.

[0094] The battery rack and battery swapping station based on this invention offer a stable structure and save upper space within the swapping station. Structurally, the battery rack adopts a narrow-at-the-top, wide-at-the-bottom design, providing sufficient space for buffering, housing, and charging vehicle batteries while maintaining a compact and stable overall structure. Furthermore, the upper space is freed up for wiring within the swapping station enclosure, significantly improving space utilization. In addition, the battery rack can be processed in layers, reducing manufacturing complexity.
