[0041] The terms "first", "second", etc. in the specification of the utility model are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the embodiments of the utility model can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are usually of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0042] Aiming at the problem that some battery swapping equipment has poor positioning effect when positioning the battery, the utility model provides a positioning device, a battery swapping equipment and a battery swapping station.

[0043] like Figure 1 As shown, the embodiment of the utility model provides a positioning device, including:

[0044] A carrying platform 1 for carrying a battery tray (the battery tray can be called a battery box), wherein a first through hole 101 is arranged on the carrying platform 1, wherein a power battery is arranged on the battery tray, and the power battery and the battery tray are stored in a storage device of the battery swap station, and are transported to the carrying platform 1 by the storage device when the battery is swapped.

[0045] The shape of the first through hole may be circular or rectangular. In the present embodiment, the first through hole 101 being rectangular is taken as an example for description.

[0046] A floating platform is arranged below the carrying platform 1 and connected with the carrying platform 1, and the floating platform can drive the carrying platform 1 to rise or fall, wherein the number of the carrying platforms 1 can be one or more, that is, multiple carrying platforms 1 can be arranged on the floating platform, and a slide rail 2 is fixedly arranged on the floating platform, and the battery exchange equipment also includes a grabbing structure 3 connected with the slide rail 2, and the grabbing structure 3 can slide on the slide rail 2. The grabbing structure 3 is used to grab the battery tray on the storage device, grab the battery tray and the power battery to the carrying platform 1, and grab the power battery after the battery exchange is completed and place it in the storage device. Specifically, the grabbing structure 3 includes a grabbing rod 301, which can rise or fall. When grabbing, the grabbing rod 301 rises, and after being connected with the grabbing hole on the battery tray, the grabbing structure 3 moves on the slide rail 2 to grab the battery tray and the power battery to the supporting platform 1, or, after the power battery that has been replaced on the supporting platform 1 is grabbed and placed in a storage device, the grabbing rod 301 falls, the grabbing structure 3 moves on the slide rail 2, and the grabbing structure 3 retracts.

[0047] The positioning device provided in the embodiment of the utility model provides two positioning methods. The first positioning method is that a positioning block is provided on the side of the battery tray, a positioning platform 4 is provided on the side of the floating platform, and a first groove is provided on the top of the positioning platform 4, that is, Figure 1 As shown, the positioning platform 4 can be a U-shaped positioning block. As the carrying platform 1 descends, the first groove is connected with the positioning block to realize the positioning and fixation of the battery tray. As the carrying platform 1 rises, the positioning block is separated from the first groove. It should be noted that the size and opening depth of the first groove can be determined according to the size of the positioning block. It should be noted that the number of the positioning platforms 4 can be multiple, and correspondingly, the number of positioning blocks can also be multiple. For example, the number of positioning platforms 4 is two, the number of positioning blocks is two, the two positioning platforms 4 are symmetrically arranged, and the two positioning blocks are symmetrically arranged to ensure the positioning effect.

[0048] The second positioning method is that a positioning hole is provided below the battery tray, and a first positioning column 5 is provided on the floating platform. As the carrying platform 1 descends, the first positioning column 5 passes through the first through hole 101 and is connected with the first positioning hole to achieve positioning and fixing of the battery tray. As the carrying platform 1 rises, the first positioning hole is separated from the first positioning column 5. It should be noted that the number of the first positioning columns 5 is multiple, and correspondingly, the number of the first positioning holes is also multiple. For example, Figure 1As shown, there are four first positioning columns 5, four first positioning holes, and two supporting platforms 1. Every two first positioning columns 5 pass through a first through hole 101 on the supporting platform 1 and are connected with the first positioning holes to ensure the positioning effect.

[0049] The first positioning method mentioned above can be called rough positioning, and the second positioning method can be called fine positioning. Preferably, in order to ensure the positioning accuracy, the positioning device provided in the embodiment of the utility model first uses the first positioning method and then uses the second positioning method to position and fix the battery tray. That is, the battery tray and the power battery are first grabbed onto the carrying platform 1 by the grabbing structure 3, the carrying platform 1 descends, the battery tray contacts the floating platform, and then the positioning block cooperates with the first groove on the positioning platform 4 to achieve rough positioning, and the first positioning column 5 cooperates with the first positioning hole to achieve fine positioning.

The number of the first floating plates 6 is equal to the number of the supporting platforms 1. When the number of the supporting platforms 1 is two, the number of the first floating plates 6 is two, and one or more first positioning columns 5 are arranged on each first floating plate 6.

[0053] In the horizontal direction, the area of ​​the first through hole 101 is greater than or equal to the area of ​​the first floating plate 6.
