[0034] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

[0036] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0037] First refer to Figure 1 and Figure 2 , the battery transport device of the present application is described.

[0038] like Figure 1 and Figure 2 As shown, in order to solve the problem of poor compatibility of the existing battery transport device, the battery transport device of the present application includes a main frame 1, a lifting part 2, a first telescopic fork 41, a second telescopic fork 42, a first adjustment mechanism 51 and a second adjustment mechanism 52. The lifting part 2 is escalably arranged on the main frame 1, and the first telescopic fork 41 and the second telescopic fork 42 are arranged on the lifting part 2. The first adjustment mechanism 51 is arranged on the lifting part 2 and connected to the first telescopic fork 41, and the first adjustment mechanism 51 is arranged to be able to drive the first telescopic fork 41 to move in a direction close to or away from the second telescopic fork 42. The second adjustment mechanism 52 is arranged on the lifting part 2 and connected to the second telescopic fork 42, and the second adjustment mechanism 52 is arranged to be able to drive the second telescopic fork 42 to move in a direction close to or away from the first telescopic fork 41.

[0039] During the use of the battery transfer device, the lifting part 2 can be lifted and lowered relative to the main frame 1 to align the target battery on the battery rack. Then the first telescopic fork 41 and the second telescopic fork 42 are extended, and both are extended to the lower side of the target battery. At this time, the lifting part 2 rises to a certain height again to lift the target battery. Then the first telescopic fork 41 and the second telescopic fork 42 are retracted, driving the target battery out of the battery rack together. Then, the lifting part 2 moves again to dock with the battery exchange robot and transfers the battery to the battery exchange robot. When the specifications of the target battery do not match the current spacing between the two telescopic forks, the positions of the first telescopic fork 41 and the second telescopic fork 42 can be adjusted respectively by the first adjustment mechanism 51 and the second adjustment mechanism 52, thereby adjusting the spacing between the two so that the spacing between the two telescopic forks matches the specifications of the target battery.

[0040] It can be seen that the battery transfer device of the present application can adjust the positions of the first telescopic fork 41 and the second telescopic fork 42 respectively by setting the first adjustment mechanism 51 and the second adjustment mechanism 52, thereby changing the distance between the first telescopic fork 41 and the second telescopic fork 42, so that the battery transfer device can adapt to batteries of different specifications, improve the compatibility of the battery transfer device, and enhance the service capabilities of the battery swap station.

[0041] Combine the following Figures 1 to 3 , a specific implementation method of the present application is introduced.

[0042] like Figures 1 to 3 As shown, in a specific embodiment, the battery transport device includes a main frame 1, a lifting part 2, a base 3, a first telescopic fork 41, a second telescopic fork 42, a first adjustment mechanism 51, a second adjustment mechanism 52, a first guide mechanism 61 and a second guide mechanism 62.

[0043] The base 3 is in the shape of an elongated strip, and a track is arranged on the base 3 along the length direction, and the main frame 1 is movably arranged on the track. In the present application, a rack is arranged on the base 3, and a driving motor and a gear are arranged at the bottom of the main frame 1. The gear is meshed with the rack, and the gear is driven by the driving motor to rotate, so that the main frame 1 can automatically move along the base 3. The specific movement method and principle of the main frame 1 are conventional technical means in the field, and will not be repeated in this application.

[0044] Reference Figures 2 to 3 , the lifting part 2 includes a lifting frame 21, a first mounting seat 22, a second mounting seat 23 and a support plate 24. The lifting frame 21 is arranged in two layers, wherein the upper layer is provided with a lifting drive mechanism, and the lower layer is provided with a support plate 24, and the first mounting seat 22 and the second mounting seat 23 are fixedly mounted on the upper side of the support plate 24, and are located at opposite ends of the support plate 24. In the present application, the lifting drive mechanism includes a driving motor, a driving gear and a rack. The driving motor is arranged in the middle of the upper layer of the lifting frame 21, and the driving motor is a double-axis motor, and each of the two output shafts of the double-axis motor is provided with a driving gear, and each of the opposite sides of the main frame 1 is provided with a rack, and each driving gear is meshed with the rack on the same side. In this way, the lifting frame 21 can be lifted and lowered relative to the main frame 1 by driving the driving gear to rotate by the driving motor. The specific movement mode and principle of the lifting frame 21 relative to the main frame 1 are conventional technical means in the field, and will not be repeated in this application.

[0045] See also Figure 3The first telescopic fork 41 includes a first support rail 411, a first slide 412 and a first fork plate 413. A first telescopic driving motor is installed on the first support rail 411. The first slide 412 is slidably disposed on the first support rail 411. The first fork plate 413 is slidably disposed on the first slide 412. In this way, driven by the first telescopic driving motor, the first telescopic fork 41 can be telescoped in three stages.

[0046] Similarly, the second telescopic fork 42 includes a second support rail 421, a second slide 422 and a second fork plate 423. A second telescopic drive motor is mounted on the second support rail 421. The second slide 422 is slidably disposed on the second support rail 421. The second fork plate 423 is slidably disposed on the second slide 422. In this way, driven by the second telescopic drive motor, the second telescopic fork 42 can be telescoped in three stages.

[0047] It should be noted that the specific operation mode and implementation principle of the telescopic fork are conventional technical means in the field and will not be described in detail in this application.

[0048] Continue to see Figure 3 The first adjustment mechanism 51 includes a first adjustment motor 511, a first adjustment transmission assembly 512 and a first intermediate transmission assembly (not shown in the figure). The first adjustment motor 511 is installed on the inner side of the first mounting seat 22, that is, on the side facing the second mounting seat 23. The first adjustment motor 511 is a reduction motor, and the output end of the reduction motor extends to the outside of the first mounting seat 22. The first adjustment transmission assembly 512 is a first screw nut assembly, and the two ends of the first screw in the first screw nut assembly are rotatably connected to the first mounting seat 22 and the second mounting seat 23, and the end of the first screw close to the first adjustment motor 511 extends to the outside of the first mounting seat 22. The first nut in the first screw nut assembly is screwed on the first screw, and the first nut is fixedly connected to the first support rail 411 of the first telescopic fork 41. The first intermediate transmission assembly in the present application can be a gear chain assembly, and the output end of the first adjustment motor 511 is connected to the end of the first screw extending from the first mounting seat 22 through the gear chain assembly.

[0049] Thus, when the first adjustment motor 511 is started, the first intermediate transmission assembly and the first adjustment transmission assembly 512 can drive the first telescopic fork 41 to move along the length direction of the first lead screw, thereby adjusting the distance between the first telescopic fork 41 and the second telescopic fork 42 .

[0050] Similarly, the second adjustment mechanism 52 includes a second adjustment motor 521, a second adjustment transmission assembly 522, and a second intermediate transmission assembly (not shown in the figure). The second adjustment motor 521 is installed on the inner side of the second mounting seat 23, that is, on the side facing the first mounting seat 22. The second adjustment motor 521 is a reduction motor, and the output end of the reduction motor extends to the outside of the second mounting seat 23. The second adjustment transmission assembly 522 is a second screw nut assembly, and the two ends of the second screw in the second screw nut assembly are rotatably connected to the first mounting seat 22 and the second mounting seat 23, and one end of the second screw close to the second adjustment motor 521 extends to the outside of the second mounting seat 23. The second nut in the second screw nut assembly is screwed on the second screw, and the second nut is fixedly connected to the second support rail 421 of the second telescopic fork 42. The second intermediate transmission assembly in the present application can be a gear chain assembly, and the output end of the second adjustment motor 521 is connected to one end of the second screw extending from the second mounting seat 23 through the gear chain assembly.

[0051] Thus, when the second adjustment motor 521 is started, the second intermediate transmission assembly and the second adjustment transmission assembly 522 can drive the second telescopic fork 42 to move along the length direction of the second lead screw, thereby adjusting the spacing of the second telescopic fork 42 relative to the first telescopic fork 41 .

[0052] The above arrangement, by providing the first mounting seat 22 and the second mounting seat 23, is conducive to reducing the difficulty of installing the first adjustment mechanism 51 and the second adjustment mechanism 52. By installing the first adjustment motor 511 on the side of the first mounting seat 22 facing the second mounting seat 23, and installing the second adjustment motor 521 on the side of the second mounting seat 23 facing the first mounting seat 22, it is conducive to reducing the occupied space of the first adjustment mechanism 51 and the second adjustment mechanism 52 and reducing motion interference.

[0053] Reference Figures 1 to 3 The first guide mechanism 61 includes a first slide rail 611 and two first sliders 612. The first slide rail 611 is fixedly installed on one side of the lifting frame 21. The two first sliders 612 are slidably connected to the first slide rail 611. One end of the first support rail 411 and one end of the second support rail 421 are respectively connected to a first slider 612. The second guide mechanism 62 includes a second slide rail 621 and two second sliders 622. The second slide rail 621 is fixedly connected to the other side of the lifting frame 21 and is arranged parallel to the first slide rail 611. The two second sliders 622 are slidably connected to the second slide rail 621. The other end of the first support rail 411 and the other end of the second support rail 421 are respectively connected to a second slider 622.

[0054] In this way, in the process of adjusting the distance between the first telescopic fork 41 and the second telescopic fork 42, the first guide mechanism 61 and the second guide mechanism 62 can provide support and guidance, thereby improving the operation stability of the first adjustment mechanism 51 and the second adjustment mechanism 52. Since the first guide mechanism 61 is connected to the first support rail 411 and the second support rail 421 at the same time, and the second guide mechanism 62 is connected to the first support rail 411 and the second support rail 421 at the same time, space can be saved and structural complexity can be reduced.

[0055] 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.

[0056] For example, the specific movement mode of the main frame 1 is not limited in this application. In addition to the combination of a drive motor and a gear rack, those skilled in the art can also make adjustments as long as the main frame 1 can move relative to the base 3. In addition, the base 3 is not necessary. For example, when the main frame 1 is moved by setting a drive wheel, the base 3 can also be omitted. In addition, whether the main frame 1 is movably set is also optional for those skilled in the art according to the specific application scenario. In some application scenarios, the main frame 1 can be fixed.

[0057] For another example, the specific driving method of the lifting frame 21 is not limited in this application. In addition to the above-mentioned combination of the motor and the driving gear and rack, those skilled in the art can also make adjustments as long as the lifting frame 21 can be lifted relative to the main frame 1. For example, the lifting frame 21 can also be lifted by combining a motor with a transmission chain or a lead screw nut, and the motor can be set on the main frame 1.

[0058] For another example, the specific setting method of the lifting part 2 is not unique, and those skilled in the art can adjust it. For example, the lifting part 2 can only include the lifting frame 21, and the first mounting seat 22, the second mounting seat 23 and the support plate 24 are omitted. For another example, the lifting frame 21 can also be a single-layer frame or a single / double-layer plate-like structure, as long as it can effectively carry the components installed thereon. For another example, the support plate 24 can also be replaced with a support rib or a support frame, as long as the first mounting seat 22 and the second mounting seat 23 can be installed. For another example, the support plate 24 can also be omitted, and the first mounting seat 22 and the second mounting seat 23 can be directly installed on the lifting frame 21.

[0059] For another example, the specific setting mode of the first telescopic fork 41 and the second telescopic fork 42 is not fixed, and can be adjusted by those skilled in the art without departing from the principle of the present application. For example, although the first telescopic fork 41 and the second telescopic fork 42 are introduced as three-stage telescopic forks, based on different application scenarios, the two can also be changed to other telescopic forms, such as two-stage or four-stage. For another example, the specific driving form of the first telescopic fork 41 and the second telescopic fork 42 is not unique. In addition to directly connecting the corresponding telescopic drive motors to the first support rail 411 and the second support rail 421 for driving, it can also be driven in the form of a motor and a transmission component (such as a gear transmission chain, a gear set, a pulley transmission belt, etc.).

[0060] For another example, the specific arrangement of the first adjustment mechanism 51 and the second adjustment mechanism 52 is not restrictive, and those skilled in the art can adjust it as long as it does not deviate from the principle of the present application. For example, when the space position is sufficient, the first adjustment mechanism 51 and / or the second adjustment mechanism 52 can directly adopt an electric push rod, a hydraulic push rod, a pneumatic push rod, etc. For another example, the first adjustment motor 511 and the first adjustment transmission assembly 512 can also be directly connected, and the arrangement of the first intermediate transmission assembly is omitted. The second adjustment motor 521 is similar, and no further description is given. For another example, in addition to being a lead screw nut assembly, the first adjustment transmission assembly 512 can also be replaced by a gear transmission chain or a pulley transmission belt, and the second adjustment transmission assembly 522 is similar, and no further description is given. For another example, the lifting part 2 can also omit the arrangement of the first mounting seat 22 and the second mounting seat 23, and the first adjustment mechanism 51 and the second adjustment mechanism 52 can be directly installed on the lifting frame 21.

[0061] For another example, the arrangement of the first guide mechanism 61 and the second guide mechanism 62 is not unique, and those skilled in the art can adjust it. For example, the specific forms of the first guide mechanism 61 and the second guide mechanism 62 can also be replaced by a slider slot, a slider rod, etc.; for another example, two guide mechanisms can be separately arranged for the first telescopic fork 41, and another two guide mechanisms can be separately arranged for the second telescopic fork 42, rather than the first telescopic fork 41 and the second telescopic fork 42 sharing one first guide mechanism 61 and one second guide mechanism 62 at the same time. For another example, at least one of the first guide mechanism 61 and the second guide mechanism 62 can be omitted.

[0062] 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.

[0063] The present application also provides a battery swap station, which includes the battery transfer device in the above embodiment.

[0064] By adopting the above-mentioned battery transfer device in the battery swap station, the overall compatibility of the battery swap station can be improved, so that the battery swap station can be compatible with batteries of more specifications, thereby improving the service capabilities of the battery swap station.

[0065] A possible battery replacement process of the battery replacement station of the present application is introduced below.

[0066] In a possible implementation, the battery swap station includes a battery swap platform, a battery swap robot, a battery rack, and a battery transfer device. Before the battery swap begins, the battery swap station obtains the battery model of the vehicle to be swapped, and then determines whether the distance between the two telescopic forks of the battery transfer device matches the battery model. If it does not match, the first adjustment mechanism 51 and the second adjustment mechanism 52 are controlled to operate to adjust the distance between the first telescopic fork 41 and the second telescopic fork 42. During the battery swap process, the vehicle to be swapped is parked on the battery swap platform, the battery swap robot moves to the bottom of the vehicle to be swapped and removes the exhausted battery, and then the battery swap robot carries the exhausted battery to the battery transfer device and transports the exhausted battery to the two telescopic forks of the battery transfer device. Then the battery transfer device is aligned with an empty space on the battery rack by moving the main frame 1 along the base 3 and the lifting frame 21 along the main frame 1. At this time, the two telescopic forks are extended, and the lifting frame 21 is appropriately lowered to place the exhausted battery in the empty space. After placement, the two telescopic forks retract, and then continue to align with a fully charged battery on the battery rack through the movement of the main frame 1 relative to the base 3 and the lifting frame 21 relative to the main frame 1. Then the two telescopic forks extend and carry the fully charged battery. After the lifting frame 21 rises appropriately, the two telescopic forks carrying the fully charged battery retract. Next, the battery transfer device continues to dock with the battery swap robot through the movement of the main frame 1 and the lifting of the lifting frame 21, and transports the fully charged battery to the battery swap robot. Finally, the battery swap robot carries the fully charged battery and moves again to the bottom of the vehicle to be swapped, and installs the fully charged battery on the vehicle to be swapped.
