It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] Combine the following Figure 1-Figure 7 The present invention is described in detail.

[0032] Example

[0033] A miniaturized battery swap station includes a bottom platform 6, on which a battery swap robot 1 that can move in a straight line is arranged, the battery swap robot 1 includes at least two support frames 101 arranged at intervals, a lifting frame 108 is arranged between the two support frames 101, and through grooves 7 for the lifting frame 108 to move through the bottom platform 6 are opened on both sides of the bottom platform 6 along the moving direction of the battery swap robot 1.

[0034] The through slot 7 is provided on the bottom platform 6 to allow the lifting frame 108 of the battery-swapping robot 1 to further pass through the bottom platform 6, thereby increasing the lowering limit of the lifting frame 108 and being able to adapt to battery-swapping operations on vehicles with lower battery-swapping positions.

[0035] A transmission device for driving the lifting frame 108 to rise and fall is installed on the support frame 101, a telescopic arm 125 is installed on the lifting frame 108, a sling 126 is provided at the telescopic end of the telescopic arm 125, a guide rail 123 is vertically arranged on the support frame 101, and a first lifting guide wheel 120, a second lifting guide wheel 121 and a third lifting guide wheel 124 cooperating with the guide rail 123 are provided on the lifting frame 108. The first lifting guide wheel 120 and the third lifting guide wheel 124 are clamped on both sides of the guide rail 123, and the second lifting guide wheel 121 is in contact with the end surface of the guide rail 123.

[0036] The lifting frame 108 is lifted and lowered through the transmission device to drive the telescopic arm 125 to adjust the height position. After the hanger 126 fixes the battery 200, the position of the battery 200 is adjusted by lifting the lifting frame 108, moving the support frame 101, and extending and retracting the telescopic arm 125, thereby installing the battery 200.

[0037] During the lifting process of the lifting frame 108, the first lifting guide wheel 120, the second lifting guide wheel 121 and the third lifting guide wheel 125 abut and limit the three side walls of the guide rail 123 to ensure the stability of the lifting of the lifting frame 108 and reduce the wear between the guide rail 123 and the guide wheels by rolling.

[0038] The fixed end of the telescopic arm 125 is rotatably connected to the lifting frame 108, and a swing telescopic rod 110 is provided on the lifting frame 108. One end of the swing telescopic rod 110 is hinged to the fixed end of the telescopic arm 125, and the other end of the swing telescopic rod 110 is hinged to the lifting frame 108. The swing telescopic rod 110 controls the overall small-angle horizontal swing of the telescopic arm 125 through telescoping, thereby better meeting the installation requirements of the battery 200.

[0039] An arc-shaped guide groove 109 is provided on the lifting frame 108, and a roller 127 is rotatably mounted on the fixed end of the telescopic arm 125 and rolls with the arc-shaped guide groove 109. The telescopic arm 125 can achieve stable swinging by cooperating with the arc-shaped guide groove 109 through the roller 127 during the swinging process, and can also reduce the load at the rotating connection of the telescopic arm 125.

[0040] The maximum lifting height of the lifting frame 108 for the telescopic arm 125 is not less than twice the height of the battery 200. After the telescopic arm 125 lifts the battery 200, it needs to cross other placed batteries 200. In order to prevent the placed batteries 200 from affecting the movement of the battery replacement equipment, the maximum lifting height of the lifting frame 108 is set to be higher than twice the height of the battery 200. At this time, the lifted battery 200 moves above the placed battery 200. In order to facilitate the support frame 101 to cross the placed batteries 200 during movement, the support frame 101 is set as a door-shaped frame with a channel.

[0041] The specific structural features of the telescopic arm 125, the sling 126, the arc-shaped guide groove 109 and the roller 127 can be referred to the invention patent with publication number CN220220693U, which will not be elaborated here.

[0042] The transmission device includes a first driving gear 122 and a first driven gear 103 which are arranged to rotate with an interval between the upper and lower parts. The first driving gear 122 and the first driven gear 103 are meshed with a lifting chain 102. The lifting chain 102 is provided with a connecting seat 119 which is fixedly connected to the lifting frame 108. The first driving gear 122 is connected to a driving shaft 111, the driving shaft 111 is connected to a reducer 112, and the reducer 112 is connected to a lifting motor 113. The lifting motor 113 rotates the driving shaft 111 through the reducer 112, thereby driving the lifting chain 102 to drive the lifting frame 108 to rise and fall in the vertical direction. The transmission device can also use a screw lifting structure.

[0043] A travel wheel 104 is rotatably provided at the lower end of the support frame 101, a track 105 is provided below the travel wheel 104, a second driven gear is fixedly connected to the travel wheel 104, a second driving gear 118 is rotatably provided on the support frame 101, a travel chain 117 is meshedly provided on the second driving gear 118 and the second driven gear, and the second driving gear 118 is connected to a travel motor 116. The travel motor 116 drives the second driving gear 118 to rotate, and cooperates with the travel chain 117 to drive the second driven gear and the travel wheel 104 to rotate synchronously, thereby realizing the movement of the lifting mechanism.

[0044] A first reinforcing rod 114 located at the lower end of the two support frames 101 is connected between the two support frames 101, and a sliding stopper 106 that is slidably engaged on the track 105 is fixedly connected to the first reinforcing rod 114. The track 105 is an I-shaped track. When the lifting mechanism moves along the fixed track 105, the sliding stopper 106 always maintains a sliding fit with the track 105, and the sliding stopper 106 is provided with an inwardly bent hook structure, so as to cooperate with the I-shaped track 105 to prevent the lifting mechanism from derailing and overturning during the movement. Among them, the first reinforcing rod 114 can connect the two support frames 101 into a whole and enhance the structural strength.

[0045] The upper surface and both side end surfaces of the first reinforcing rod 114 are provided with buffer elastic blocks 115. The buffer elastic blocks 115 can buffer the impact force when the lifting frame 108 descends and the impact force of the supporting frame 101 and other structures after moving, so as to prevent the related structures from being damaged by impact.

[0046] The lifting frame 108 is detachably connected with a second reinforcing rod 107 perpendicular to the two support frames 101. The second reinforcing rod 107 can strengthen the structural strength of the lifting frame 108. The second reinforcing rod 107 is only used for the entire lifting mechanism transportation process. When performing subsequent battery replacement operations, the second reinforcing rod 107 needs to be removed to prevent the second reinforcing rod 107 from affecting the lifting of the battery 200.

[0047] The lower end of the support frame 101 extends into the through slot 7 , and the support frame 101 can cooperate with the through slot 7 to limit the moving direction of the running wheel 104 , and then cooperate with the sliding limit seat 106 to keep the running wheel 104 stably on the track 105 .

[0048] Support parts 3 are respectively provided on both sides of the bottom of the bottom platform 6. The support parts 3 lift the bottom platform 6 a certain distance from the ground, so that there is more space at the bottom of the bottom platform 6 for the lifting frame 108 to move down. The support part 3 has the function of telescopic adjustment, which includes a sleeve connected to the bottom platform 6 and a screw threaded in the sleeve. The length of the support part 3 is adjusted by rotating the screw to adapt to the support of uneven ground.

[0049] The bottom of the bottom platform 6 is provided with a sinking bin 4 connected to the through slot 7. The sinking bin 4 can protect the lower ends of the lifting frame 108 and the supporting frame 101 to prevent the lifting frame 108 and the supporting frame 101 from being damaged.

[0050] In the existing patents in the background technology, when replacing batteries, it is necessary to place batteries on one side of the battery replacement device, and the battery replacement device lifts the batteries to the other side for battery replacement. Since the telescopic arm has a large stroke, a long operating time, and a large area occupied. Compared with the above-mentioned existing patents, the present application can be miniaturized. Specifically: Several battery compartments 8 located between two through slots 7 are provided on the bottom platform 6, one of which is not provided with a charging connector, and the remaining battery compartments 8 are provided with charging connectors. A cable box 9 connected to the charging connector is provided at the bottom of the bottom platform 6. When replacing the battery 200, the telescopic arm 125 of the present application only needs to move half the stroke of the telescopic arm in the existing patent, which takes a short time and improves the efficiency of battery replacement. At the same time, it occupies a small area, which is conducive to a wide range of arrangements.

[0051] The battery compartment 8 without a charging connector is used to transfer the battery 200, that is, the battery-swapping robot 1 places the low-power battery 200 on the battery compartment 8 without a charging connector, and then installs the fully charged battery 200 on the truck. The battery compartment 8 with a charging connector is also equipped with a locking mechanism (the locking mechanism is a prior art), which guides the battery 200 so that the battery 200 is aligned and inserted into the charging connector and locked.

[0052] A container protective shell 2 is provided on the bottom platform 6 and is located outside the battery swap robot 1. A window 5 is provided on the container protective shell 2. Two container protective shells 2 are provided above and below, and only the container protective shell 2 located below is shown in the figure. The container protective shell 2 located above is opened downward and is spliced ​​with the container protective shell 2 below to form a protective cover to protect the battery 200 and the battery swap robot 1.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
