DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Combine the following Figures 1 to 8 The power replacement device of the utility model is described.

[0041] like Figures 1 to 8 As shown, the embodiment of the utility model provides a battery swapping device, including a battery swapping chassis and at least one fork picking system 2. Specifically, as Figure 6 As shown, in some embodiments of the present invention, the fork picking system 2 is a set, and the fork picking system 2 is arranged on the battery replacement chassis. Figure 4 As shown, the fork picking system 2 includes a fork arm 21, a lifting body 22 and a supporting body 23. The fork arm 21 is used to fork the battery 1, and the fork arm 21 is connected to the lifting body 22, such as by welding or bolting, so that the fork arm 21 moves together with the lifting body 22.

[0042] like Figure 6 As shown, the lifting body 22 is movably connected to the supporting body 23, and the lifting body 22 performs lifting movement along the first direction 6 in the figure, thereby driving the battery 1 to perform lifting movement through the fork arm 21, so as to take and place the battery 1. The supporting body 23 is movably connected to the battery exchange chassis, and the supporting body 23 moves along the second direction 7 in the figure to pull the battery 1 to move horizontally on the battery exchange chassis, thereby realizing the transfer of the battery 1 between the battery compartment and the battery exchange heavy truck. Among them, the first direction 6 and the second direction 7 are perpendicular to each other.

[0043] With such arrangement, the lifting body 22 drives the fork arm 21 to perform lifting movement, thereby driving the battery 1 to perform lifting movement, and the supporting body 23 drives the lifting body 22 and the fork arm 21 to perform translational movement together, thereby pulling the battery 1 to translate on the battery replacement chassis, thereby realizing the battery replacement operation of the heavy truck battery. Compared with the traditional fork mechanism, its structure is simple and the cost is low.

[0044] In the embodiment of the utility model, the forking system 2 also includes a first guide mechanism, which is arranged between the support body 23 and the battery exchange chassis, and the first guide mechanism is arranged along the second direction 7. In this way, the first guide mechanism guides and positions the movement of the support body 23, making the movement more stable and reliable, ensuring that the relative movement between the components during the battery exchange process is accurate and smooth, which helps to improve the accuracy of battery exchange and reduce failures and delays caused by improper operation or errors.

[0045] In a specific embodiment of the present invention, the first guide mechanism includes a slider 24 and a guide rail 25. Figure 8 As shown, the slider 24 is arranged on the support body 23, for example, it can be connected by bolts. The guide rail 25 is arranged on the battery exchange chassis, for example, it can be connected by bolts. And the guide rail 25 is arranged along the second direction 7, and the slider 24 is slidably connected to the guide rail 25 and moves along the guide rail 25. Therefore, the slider cooperates with the linear guide rail to achieve translation along the second direction 7, ensuring that the relative movement between the support body 23 and the battery exchange chassis can be carried out accurately and smoothly during the battery exchange process, providing precise guidance, and ensuring the accuracy and stability of the battery exchange process.

[0046] Furthermore, if Figure 6 As shown, the first guide mechanism can be set to two groups, the two groups of first guide mechanisms are spaced apart, and there are at least two sliders 24 in each group of first guide mechanisms, so as to achieve more precise battery replacement operation and ensure the accuracy, stability and efficiency of the battery replacement process. Of course, in other embodiments, the first guide mechanism includes but is not limited to a combination of a slider and a linear guide rail, and other common guide mechanisms such as rollers and guide rail grooves can also be used.

[0047] In an optional embodiment of the utility model, the fork picking system 2 further includes a lifting drive mechanism and a translation drive mechanism. Specifically, the lifting drive mechanism is used to drive the lifting body 22 to move along the first direction 6, thereby realizing the lifting of the battery 1. The translation drive mechanism is used to drive the support body 23 to move along the second direction 7, thereby realizing the translation of the battery 1.

[0048] Specifically, Figure 5 As shown, the lifting drive mechanism includes a lifting drive member 26 and a lead screw 27. For example, the lifting drive member 26 is a motor, and the motor is fixedly mounted on the support body 23. The motor can be connected to the lead screw 27 through a reduction gearbox, and the motor is used to drive the lead screw 27 to rotate. The lead screw 27 is arranged along the first direction 6, and the lead screw 27 is threadedly connected to the lifting body 22. In this way, the motor drives the lead screw 27 to rotate, and then under the action of the thread cooperation, the lifting body 22 moves up and down along the first direction 6. Furthermore, a second guide mechanism is also provided between the support body 23 and the lifting body 22. The second guide mechanism can adopt a slider guide rail combination, a roller guide rail combination, etc., to play a limiting and guiding role for the lifting body 22, so that it can stably perform lifting and lowering movements along the first direction 6. It should be noted that, as shown in Figure 5 For the placement position of the forking system 2 shown in the figure, the up and down directions in the figure are the up and down directions.

[0049] like Figure 3As shown, the translation drive mechanism includes a translation drive member 28, a gear 29 and a rack 210. For example, the translation drive member 28 uses a motor, which is fixedly mounted on the support body 23. The motor can be connected to the gear 29 through a reduction box, and the motor is used to drive the gear 29 to rotate. The gear 29 is meshed with the rack 210, and the rack 210 is arranged along the second direction 7. In this way, the motor drives the gear 29 to rotate, and the gear 29 moves along the rack 210, thereby realizing the reciprocating motion of the support body 23 along the second direction 7. Of course, in other embodiments, the lifting drive mechanism and the translation drive mechanism include but are not limited to a motor and a ball screw, a motor and a gear rack, and other conventional forms such as a motor and a sprocket chain can also be used, and adaptive adjustments are made to achieve linear reciprocating motion. In addition, the lifting drive member and the translation drive member include but are not limited to a motor, and can also be driven by a motor.

[0050] As an optional embodiment of the present utility model, Figure 2 As shown, the fork arms 21 are a pair, and the pair of fork arms 21 are respectively arranged on both sides of the lifting body 22. Specifically, the pair of fork arms 21 are spaced apart along the third direction 8. At least two protrusions are respectively provided on the two opposite sides of the battery 1, and the pair of fork arms 21 are respectively supported on the protrusions on both sides to achieve forking the battery 1. In this way, the battery 1 can be forked more stably through the pair of fork arms 21, which improves the structural strength of the system and ensures the safety and reliability of the battery replacement process.

[0051] In an optional embodiment of the present utility model, the battery-swapping chassis includes a walking system 4 and a track 5. Specifically, Figure 1 As shown, the track 5 is arranged along the third direction 8, wherein the third direction 8, the first direction 6 and the second direction 7 are mutually perpendicular to each other to form a three-dimensional rectangular coordinate system. Further, there are two tracks 5, which are spaced apart along the second direction 7.

[0052] The walking system 4 is movably connected to the track 5 and moves along the track 5. The support body 23 is movably arranged on the walking system 4 and moves along the second direction 7. Specifically, the walking system 4 can adopt an existing mature walking device, so its specific structure is not repeated here. For example, the walking system 4 can move along the third direction 8 through a drive form such as an electric cylinder, a gear rack, a sprocket chain, etc. Further, the walking system 4 also includes a third guide mechanism, which can be in the form of a wheel track, a slider guide rail, a composite roller and a track groove, so that the walking system 4 can move reliably along the track 5.

[0053] Furthermore, in a specific embodiment of the present invention, the battery-swap chassis further includes a slewing system 3, which is rotatably connected to the traveling system 4, so that the slewing system 3 can rotate relative to the traveling system 4. At the same time, the support body 23 can be movably arranged on the slewing system 3 and move along the second direction 7. Specifically, as Figure 6 As shown, the rotary system 3 includes a rotary platform 31, a rotary bearing 32, a pinion and a rotary drive. For example, the rotary drive is a motor, which is fixedly mounted on the travel system 4. The motor can be connected to the pinion through a reducer, and the motor is used to drive the pinion to rotate. The rotary bearing 32 is meshed with the pinion, and the rotary bearing 32 is arranged between the travel system 4 and the rotary platform 31. The rotary bearing 32 can drive the rotary platform 31 to rotate. The support body 23 is movably connected to the rotary platform 31 and moves along the second direction 7. In this way, the motor drives the pinion to rotate, thereby driving the rotary bearing 32 to rotate. The rotary bearing 32 drives the rotary platform 31, the fork system 2 and the battery 1 to rotate together, so that the angle can be adjusted according to the position of the battery to be replaced, so as to more accurately align the battery 1 and improve the battery replacement efficiency.

[0054] Generally, the slewing bearing 5 is located at the center of the battery exchange device, and the center of gravity of the entire device is maintained at the center position to ensure that the entire device is stable and reliable. The slewing bearing 32 is an existing commonly used product, which can simultaneously withstand large axial loads, radial loads and overturning moments. The slewing bearing 5 includes an inner ring and an outer ring, and has two working modes. The inner ring can be fixed to play a supporting role, and the outer ring can rotate, or the outer ring can be fixed to play a supporting role, and the inner ring can rotate. The specific method can be determined according to the actual application. For example, Figure 6 As shown, the inner ring is fixedly connected to the travel system 4, the outer ring rotates, and the outer ring is fixedly connected to the slewing platform 31, so that the slewing bearing 32 drives the slewing platform 31 to rotate synchronously, and the travel system 4 and the slewing platform 31 are connected as a whole through the slewing bearing 32.

[0055] In other embodiments of the present invention, Figure 1 As shown, there are two fork-picking systems 2, and the two fork-picking systems 2 are arranged oppositely on the battery-changing chassis. Specifically, the two fork-picking systems 2 are arranged oppositely on the rotating platform 31.

[0056] Or, in some other embodiments of the present invention, Figure 7 As shown, there are two fork-taking systems 2, and the two fork-taking systems 2 are arranged on the battery-changing chassis in the same direction. Specifically, the two fork-taking systems 2 are arranged on the rotating platform 31 in the same direction.

[0057] In this way, by designing two sets of side-insertion grabbing structures, the battery replacement speed can be faster and the battery replacement efficiency can be higher, meeting the vehicle's rapid battery replacement needs. At the same time, the two grabbing devices serve as backup for each other, which can minimize the impact of equipment failure on vehicle battery replacement operations and ensure the reliable operation of the system.

[0058] The battery swap station provided by the present invention is described below. The battery swap station described below and the battery swap equipment described above can be referenced to each other.

[0059] The embodiment of the utility model also provides a battery swap station, including the battery swap equipment as described in the above embodiments. In this way, the lifting body 22 drives the fork arm 21 to perform lifting and lowering movements, thereby driving the battery 1 to perform lifting and lowering movements, and the supporting body 23 drives the lifting body 22 and the fork arm 21 to perform translational movements together, thereby pulling the battery 1 to translate on the battery swap chassis, thereby realizing the battery swap operation of the heavy truck battery. Compared with the traditional fork mechanism, its structure is simple and the cost is low. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the above-mentioned battery swap equipment, so it will not be repeated here.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
