[0039] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] See Figures 1 to 9This application provides an embodiment of an automatic battery swapping device for new energy electric vehicles with auxiliary mobility function. The device includes: a base shell 10, a support frame 20, a first lifting assembly 30, a first moving assembly 40, a first battery transfer assembly 50, and an auxiliary support assembly 60. The top wall of the base shell 10 has a first opening 11. The support frame 20 is movably mounted in the first opening 11, and a second opening 21 is provided on the support frame 20. The first lifting assembly 30 is located inside the base shell 10 and connected to the support frame 20, and is used to drive the support frame 20 to move up and down.

[0041] Please see Figure 5 , Figure 6 and Figure 8 The first moving component 40, the first battery transfer component 50 and the auxiliary support component 60 are all located inside the bottom shell 10. The first moving component 40 is connected to the first battery transfer component 50 and the auxiliary support component 60 respectively. The first moving component 40 is used to drive the first battery transfer component 50 or the auxiliary support component 60 to move to a position directly opposite the second opening 21.

[0042] The aforementioned automatic battery swapping device for new energy electric vehicles with auxiliary mobility function is used such that the auxiliary support component 60 is positioned directly opposite the second opening 21 (e.g., Figure 5 (As shown), the electric vehicle is then moved to the top wall of the bottom shell 10. Even if the position of the electric vehicle shifts and the wheels press into the second opening 21, the auxiliary support component 60, located in the second opening 21, provides support for the wheels, thereby improving safety. After the electric vehicle is moved into place, the first lifting component 30 drives the support frame 20 to move up and down, raising the support frame 20 and the electric vehicle above it to a preset height. The first moving component 40 drives the auxiliary support component 60 to move away and moves the first battery transfer component 50 to a position directly opposite the second opening 21, so that the battery can be replaced through the second opening 21 via the first battery transfer component 50.

[0043] In some embodiments, the shapes of the first opening 11 and the second opening 21 are independently configured, and both include, but are not limited to, regular shapes such as polygons, circles, or ellipses, as well as other irregular shapes. Among them, polygons include, for example, rectangles, triangles, pentagons, hexagons, etc.

[0044] In some embodiments, the second opening 21 can be located at any part of the support frame 20. In this embodiment, it is specifically located at the middle part of the support frame 20, so that when the electric vehicle is moved into place, the position of the second opening 21 is close to the battery installation position of the electric vehicle.

[0045] Please see Figure 5 and Figure 6In some embodiments, the first lifting assembly 30 is, but is not limited to, installed on the bottom wall or side wall of the bottom shell 10, for example, four are configured and located at the four corners of the bottom shell 10 respectively. The four first lifting assemblies 30 synchronously drive the support frame 20 to rise or fall, resulting in good operational stability. The first lifting assembly 30 is, but is not limited to, configured as various drive structures such as cylinders, electric cylinders, hydraulic cylinders, motor screws, and motor cams.

[0046] Please see Figure 5 , Figure 8 and Figure 9 In one embodiment, the auxiliary support assembly 60 includes a support plate 61 and at least one buffer assembly 62. The support plate 61 is connected to the first moving assembly 40 via the buffer assembly 62. Thus, when the wheels of the electric vehicle move through the second opening 21, the buffer assembly 62 cushions the wheels of the electric vehicle, improving safety.

[0047] Specifically, multiple buffer components 62 are provided, and the support plate 61 is connected to the first moving component 40 through the multiple buffer components 62 respectively. Since each buffer component 62 bears the force of the support plate 61, the support effect of the support plate 61 is more stable and the load-bearing capacity is greater.

[0048] In some embodiments, the support plate 61 includes, but is not limited to, being adapted to the second opening 21. Furthermore, before the electric vehicle travels to the support frame 20, the support plate 61 is located in the second opening 21 and flush with the top surface of the support frame 20.

[0049] Please see Figure 5 , Figure 8 and Figure 9 In one embodiment, the auxiliary support assembly 60 further includes a first mounting plate 63 disposed between the buffer assembly 62 and the first moving assembly 40. The buffer assembly 62 is connected to the first mounting plate 63, and the first mounting plate 63 is connected to the first moving assembly 40. Thus, by means of the first mounting plate 63, especially when there are a large number of buffer assemblies 62, the auxiliary support assembly 60 can be easily mounted on the first moving assembly 40.

[0050] In one embodiment, the buffer component 62 includes, but is not limited to, an elastic post 621, an elastic rod, or an elastic block.

[0051] Please see Figure 5 , Figure 8 and Figure 9In one embodiment, the buffer assembly 62 includes a guide tube 622, a guide rod 623, a first elastic element 624, and a second elastic element 625. The guide tube 622 is connected to the first moving assembly 40, and the guide rod 623 passes through the guide tube 622. One end of the guide rod 623 is connected to the first moving assembly 40 through the first elastic element 624, and the other end of the guide rod 623 is connected to the support plate 61 through the second elastic element 625.

[0052] Specifically, one end of the guide tube 622 is connected to the first mounting plate 63, thereby indirectly connected to the first moving component 40; in addition, the first elastic member 624 is disposed inside the guide tube 622 and connected to the first mounting plate 63, that is, indirectly connected to the first mounting plate 63.

[0053] In some embodiments, the first elastic element 624 and the second elastic element 625 are each independently provided, including but not limited to various elastic elements such as elastic blocks, springs, and elastic pads.

[0054] Among them, the elastic column 621, elastic rod, elastic block, spring, elastic pad, etc. are made of materials including but not limited to rubber and metal.

[0055] Please see Figure 5 and Figure 8 In one specific embodiment, the four corners of the support plate 61 are connected to the first mounting plate 63 via four elastic posts 621. Furthermore, the first mounting plate 63 has multiple guide tubes 622 in its central portion, each containing a spring. The support plate 61 has multiple guide rods 623 in its central portion. The top of each guide rod 623 is connected to the bottom surface of the support plate 61 via an elastic block, and the bottom of each guide rod 623 extends into the guide tube 622 and abuts against the spring. Thus, when a wheel travels on the support plate 61, the springs and support posts provide support, while simultaneously buffering the forces borne by the support plate 61, effectively ensuring safety.

[0056] Please see Figure 6 , Figure 8 and Figure 9 In one embodiment, the first moving component 40 includes a base plate 41 connected to the bottom shell 10, a movable plate 42 slidably disposed on the base plate 41, and at least one first driving component 43 connected to the movable plate 42. The first driving component 43 is used to drive the movable plate 42 to move back and forth on the base plate 41. The first battery transfer component 50 and the auxiliary support component 60 are both disposed on the movable plate 42. Thus, when the first driving component 43 drives the movable plate 42 to move back and forth on the base plate 41, the movable plate 42 drives the first battery transfer component 50 and the auxiliary support component 60 to move, thereby adjusting the first battery transfer component 50 or the auxiliary support component 60 to a position directly opposite the second opening 21.

[0057] It should be noted that the "substrate 41" can be a "part of the bottom shell 10", that is, the "substrate 41" and the "other parts of the bottom shell 10" can be integrally formed; or it can be a separate component that can be separated from the "other parts of the bottom shell 10", that is, the "substrate 41" can be manufactured independently and then combined with the "other parts of the bottom shell 10" to form a whole.

[0058] In some embodiments, the substrate 41 is, but is not limited to, connected to the bottom wall or side wall of the bottom shell 10.

[0059] Please see Figure 6 , Figure 8 and Figure 9 In some embodiments, the movable plate 42 is slidably disposed on the base plate 41. Specifically, the base plate 41 is provided with a groove 411, and the movable plate 42 is provided with a slider 421 that slides in cooperation with the groove 411. The slider 421 may be one, two or more, and the more sliders 421 there are, the higher the operational stability of the movable plate 42.

[0060] Please see Figure 6 and Figure 8 In one embodiment, the first drive assembly 43 includes a first motor 431 and a gear 432 connected to the shaft of the first motor 431. A rack 433 is provided on the movable plate 42, and the gear 432 meshes with the rack 433. The first motor 431 is connected to the base shell 10. Thus, when the first motor 431 is working, it drives the gear 432 to rotate, which in turn drives the rack 433 to move, and the rack 433 accordingly drives the movable plate 42 to reciprocate.

[0061] In one embodiment, each of the first motors 431 is fixedly connected to a base 434 at its bottom, and the bottom of each base 434 is fixedly connected to the bottom of the inner wall of the bottom shell 10. This arrangement ensures that the first motor 431 is completely fixed, making it more stable during subsequent operation.

[0062] In some embodiments, the first drive component 43 may be configured as one and disposed on one side of the movable plate 42, or it may be two and located on opposite sides of the movable plate 42 respectively.

[0063] Please see Figure 6 When the first drive component 43 is set to two and located on opposite sides of the movable plate 42, it can easily drive the movable plate 42 to move, thereby easily switching the position of the support plate 61 and the first battery transfer component 50, which also facilitates switching between the functions of support and battery replacement.

[0064] Of course, as some optional solutions, the first drive component 43 is not limited to the structure in which the gear 432 and rack 433 cooperate with each other in the above embodiments, but can also be configured as a drive structure such as a cylinder, hydraulic cylinder, or motor screw.

[0065] Please see Figure 5 and Figure 6 In one embodiment, the first battery transfer assembly 50 includes a rotating lifting arm 51, a connecting frame 52, and a battery clamping mechanism 53. The rotating lifting arm 51 is mounted on the first moving assembly 40 and is connected to the connecting frame 52. The connecting frame 52 is connected to the battery clamping mechanism 53. The rotating lifting arm 51 can drive the connecting frame 52 to move the battery clamping mechanism 53 up, down, and rotate, allowing the battery clamping mechanism 53 to clamp and release the battery. Thus, the first battery transfer assembly 50 can perform battery replacement operations on the bottom of the electric vehicle.

[0066] The rotating lifting arm 51 includes, but is not limited to, a combination of a rotating mechanism and a lifting mechanism. Furthermore, the battery gripping mechanism 53 includes, but is not limited to, electric grippers or pneumatic grippers, which can be flexibly adjusted and configured according to actual needs.

[0067] In one embodiment, the first battery transfer assembly 50 further includes a second mounting plate 54. The rotating lifting arm 51 is mounted on the first moving assembly 40 via the second mounting plate 54. Specifically, the first mounting plate 63 and the second mounting plate 54 are spaced apart from each other and respectively connected to the movable plate 42.

[0068] It should be noted that the "first mounting plate 63 and the second mounting plate 54" can be "part of the movable plate 42", that is, the "first mounting plate 63 and the second mounting plate 54" can be integrally molded with the "other parts of the movable plate 42"; or they can be separate components from the "other parts of the movable plate 42", that is, the "first mounting plate 63 and the second mounting plate 54" can be manufactured independently and then combined with the "other parts of the movable plate 42" to form a whole.

[0069] Please see Figures 4 to 6In one embodiment, a feeding groove 12 is provided on one side wall of the bottom shell 10. The automatic battery swapping device for new energy electric vehicles with auxiliary movement function also includes a second moving component 70, a second battery transfer component 80, and a transfer mechanism 91 disposed inside the bottom shell 10 and located on one side of the movable plate 42. The second moving component 70 is used to transport batteries and switch between loading / unloading positions and transfer positions, with the transfer position corresponding to the position of the transfer mechanism 91. The second battery transfer component 80 is used to transfer batteries from the second moving component 70 to the transfer mechanism 91, or to transfer batteries from the transfer mechanism 91 to the second moving component 70. The first battery transfer component 50 is used to transfer batteries to the transfer mechanism 91, or to pick up batteries from the transfer mechanism 91. Thus, when replacing the battery of an electric vehicle, the battery is first removed from the electric vehicle through the first battery transfer assembly 50 located at the second opening 21 and transferred to the transfer mechanism 91. Then, the battery on the transfer mechanism 91 is transferred to the second moving assembly 70 through the second battery transfer assembly 80. The second moving assembly 70 moves the battery from the transfer position to the loading / unloading position, where the battery is removed. Then, for example, a new battery is installed on the second battery transfer assembly 80. The second battery transfer assembly 80 moves the new battery to the transfer position. The new battery on the second moving assembly 70 is moved to the transfer mechanism 91 through the second battery transfer assembly 80. Then, the first battery transfer assembly 50 grabs the new battery from the transfer mechanism 91 and moves the new battery out of the second opening 21 and onto the electric vehicle.

[0070] Among them, the transfer mechanism 91 provides a switching position for the replaced battery and the new battery, which facilitates the battery clamping component to clamp the battery, thereby facilitating the overall battery swapping operation.

[0071] Please see Figures 1 to 5 In one embodiment, a side shell 92 is provided on one side of the bottom shell 10, and a third opening 921 is provided on both the front and rear sides of the side shell 92 along the driving direction, and the second moving component 70 passes through the side shell 92.

[0072] Please see Figure 5 and Figure 10In one embodiment, the second battery transfer assembly 80 includes an electric push rod 81, a push plate 82, a sensor 83, and an electric suction cup 84. One end of the electric push rod 81 is connected to the inner wall of the side shell 92, and the other end is connected to the push plate 82. The electric suction cup 84 is disposed on the push plate 82 on a side opposite to the electric push rod 81, and the sensor 83 is connected to the push plate 82. Thus, the electric push rod 81 drives the push plate 82 to move towards the transfer mechanism 91, which can push the battery on the second moving assembly 70 from the transfer position into the transfer mechanism 91. In addition, when the electric suction cup 84 attracts the battery located in the transfer mechanism 91, the electric push rod 81 drives the battery to move away from the transfer mechanism 91, which can transfer the battery on the transfer mechanism 91 to the second moving assembly 70. Furthermore, by sensing the battery through the sensor 83, the presence of the battery can be accurately determined, and corresponding battery pushing or retraction actions can be performed based on the sensing signal.

[0073] In some embodiments, the second moving component 70 includes, but is not limited to, various structural forms such as a pulley mechanism, a sprocket mechanism, or a mechanical transmission arm.

[0074] In some embodiments, the side shell 92 includes, but is not limited to, being plugged into one side of the bottom shell 10.

[0075] In some embodiments, the specific location of the transfer mechanism 91 inside the bottom shell 10 can be flexibly adjusted and set according to actual needs, such as being set in the middle region, rear region, or front region of the bottom of the inner wall of the bottom shell 10.

[0076] Please see Figure 5 , Figure 6 and Figure 11 In one embodiment, the transfer mechanism 91 includes a receiving plate 911, a first limiting plate 912, a baffle 913, and a third elastic member 914. The receiving plate 911 is connected to the inner wall of the bottom shell 10. The first limiting plate 912 is connected to the receiving plate 911 and is connected to the baffle 913 via the third elastic member 914. The baffle 913 is slidably disposed on the receiving plate 911. Thus, when the second battery transfer mechanism pushes the battery from the second moving assembly 70 onto the receiving plate 911, and the battery contacts the baffle 913, the baffle 913 moves closer to the first limiting plate 912. The third elastic member 914 acts as a buffer, preventing the battery from directly bearing the impact force when it collides with the baffle 913. Furthermore, the baffle 913 is made of, for example, rubber, which is soft and further protects the battery, effectively improving its service life.

[0077] Specifically, the third elastic element 914 includes, but is not limited to, a reed, a spring, an elastic block, an elastic post 621, etc.

[0078] Please see Figure 5 , Figure 6 and Figure 11 In one embodiment, the transfer mechanism 91 further includes two second limiting plates 915 connected to the receiving plate 911. The two second limiting plates 915 are arranged at intervals relative to each other, and the distance between them gradually decreases in the direction close to the first limiting plate 912. The baffle 913 and the third elastic member 914 are located in the space area enclosed by the first limiting plate 912 and the two second limiting plates 915.

[0079] Please see Figure 5 , Figure 6 and Figure 11 In one embodiment, the receiving plate 911 is provided with a guide groove 9111, and the bottom wall of the baffle 913 is provided with a guide block, which is slidably disposed in the guide groove 9111. Thus, during the movement of the baffle 913, the guide block moves along the guide groove 9111, playing a guiding role; in addition, the guide block is in close contact with the inner wall of the guide groove 9111, and the friction can further achieve a buffering effect.

[0080] Please see Figures 5 to 7 and Figure 11 In one embodiment, at least one corner of the support frame 20 is provided with a through groove 22 and a limiting component 93 corresponding to the through groove 22. The limiting component 93 includes a mounting bracket 931 connected to the bottom surface of the support frame 20, a second lifting component 932 mounted on the mounting bracket 931, and a limiting block 933 connected to the second lifting component 932. The limiting block 933 is vertically and vertically disposed in the through groove 22. When the second lifting component 932 moves up and down, the limiting block 933 can extend through the through groove 22 and above the mounting bracket 931.

[0081] In some embodiments, the second lifting component 932 is similar to the first lifting component 30, and may include, but is not limited to, various drive structures such as cylinders, electric cylinders, hydraulic cylinders, motor screws, and motor cams.

[0082] In some embodiments, the mounting bracket 931 includes, but is not limited to, being configured as a U-shaped bracket.

[0083] In some embodiments, each of the four corners of the support frame 20 is provided with a through slot 22, and four limiting components 93 are correspondingly provided, each corresponding to one of the four through slots 22. Thus, when the electric vehicle moves to a suitable position on the support frame 20, each of the second lifting components 932 operates synchronously, causing the four limiting blocks 933 to extend upwards from the four through slots 22 respectively. The four limiting blocks 933 respectively limit the four wheels, further fixing the entire vehicle in a fixed state, facilitating subsequent battery swapping operations.

[0084] Please see Figure 1 and Figure 2In one embodiment, inclined panels 94 are connected to opposite sides of the bottom shell 10. One end of the inclined panel 94 is connected to the top wall of the bottom shell 10, and the other end of the inclined panel 94 is connected to the ground. In this way, the electric vehicle can smoothly travel to the top of the bottom shell 10 via the inclined panel 94, and after the battery is replaced, it can smoothly return to the ground via another inclined panel 94.

[0085] Please see Figure 1 and Figure 2 In one embodiment, movable indicator strips 95 are embedded in and installed on opposite sides of the top of the base shell 10 along the driving direction. Thus, when the electric vehicle travels to the top of the base shell 10, the movable indicator strips 95 on both sides remind the user to move the electric vehicle to the center position of the support frame 20. The movable indicator strips 95 also provide the user with information about the left and right sides, making it easier for the user to judge the space on both sides of the vehicle, thus facilitating subsequent battery swapping. Furthermore, since the movable indicator strips 95 are specifically embedded in the top of the base shell 10, they do not protrude from the top surface of the base shell 10, preventing damage. Of course, the movable indicator strips 95 can also be installed on the top of the base shell 10 by various methods, such as adhesive, snap-fit, or fastener connection.

[0086] Please see Figure 1 and Figure 2 In one embodiment, the automatic battery swapping device for new energy electric vehicles with auxiliary mobility function also includes a cover 96 connected to the top of the base 10. The cover 96 has fourth openings 961 on both the front and rear sides along the driving direction. A lamp holder 97 is provided on the inner wall of the cover 96, and multiple lights 98 are provided on the lamp holder 97. Thus, at night, the lights 98 are turned on to provide illumination for the electric vehicle above the base 10, facilitating the battery swapping operation.

[0087] In one embodiment, the lamp holder 97 is arranged on the top wall and two opposite side walls of the housing 96, and lighting lamps 98 are provided on the top wall and two opposite side walls of the housing 96, so as to have a better lighting effect.

[0088] In one embodiment, a battery swapping station is an energy station capable of providing battery swapping services for pure electric vehicles or hybrid electric vehicles. The battery swapping station is equipped with an automatic battery swapping device for new energy electric vehicles with auxiliary mobility functions as described in any of the above embodiments.

[0089] In use, the aforementioned battery swapping station positions the auxiliary support assembly 60 directly opposite the second opening 21. The electric vehicle is then moved to the top wall of the base 10. Even if the electric vehicle shifts position and its wheels become lodged in the second opening 21, the auxiliary support assembly 60, located within the opening, provides support, thus improving safety. Once the electric vehicle is in place, the first lifting assembly 30 drives the support frame 20 to rise and lower, raising the support frame 20 and the electric vehicle above it to a predetermined height. The first moving assembly 40 then moves the auxiliary support assembly 60 away and moves the first battery transfer assembly 50 to a position directly opposite the second opening 21, allowing battery swapping to be performed through the second opening 21.

[0090] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0091] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0092] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0093] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0094] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0095] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0096] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
