[0002] The battery energy storage and exchange cabinet uses automatic guided vehicle technology. In order to transfer the battery pack removed from the electric vehicle to the battery cabinet for charging, the automatic moving vehicle needs to first receive the battery and then move the battery to the battery cabinet to achieve the transfer of the battery pack. However, during the transfer of the battery pack, if the bottom of the guide vehicle contacts an obstacle and shakes, the battery pack is prone to move, causing the position of the battery pack on the guide vehicle to change.

[0039] Combine the following Figure 1-Figure 12 The invention describes an automatic guided vehicle for entering a battery energy storage and exchange cabinet.

[0040] like Figures 1 to 9 , Fig.12 As shown, in one embodiment, an automatic guided vehicle for entering a battery energy storage cabinet includes a mobile seat 1 and also includes:

[0041] Two electric slide rails 2, on which a movable slide block 3 is slidably arranged, a plug socket 4 is fixedly connected to the top of the movable slide block 3, and a bearing frame is commonly plugged into the two plug sockets 4;

[0042] A first clamping assembly, which is disposed at a first end of the carrier frame and is used to position a first end of the battery pack 5;

[0043] The second clamping assembly is arranged at the second end of the carrying frame, and the second clamping assembly is used to position the second end of the battery pack 5.

[0044] It should be understood that the battery pack 5 includes a first support body 501 and a second support body 502, the first support body 501 is located at a first end of the battery pack 5, the second support body 502 is located at a second end of the battery pack 5, the second support body 502 has an electrode 503 and a cooling joint 504 on the top, the first support body 501 has inclined surfaces on both sides, and the second support body 502 also has inclined surfaces on both sides;

[0045] Before entering the battery cabinet, since the battery pack 5 of the electric vehicle is large and heavy, after the battery pack 5 is removed, it needs to be carried and transferred to the battery cabinet by an automatic guided vehicle. The specific method of transferring the removed battery pack 5 is as follows:

[0046] The first step is to place the disassembled battery pack 5 on the top of the carrying frame, with the first support body 501 of the battery pack 5 at the first end of the carrying frame and the second support body 502 of the battery pack 5 at the second end of the battery pack 5;

[0047] In the second step, the inclined surfaces on both sides of the first support body 501 of the battery pack 5 are clamped and positioned by the first clamping assembly. With the cooperation of the inclined surfaces, the battery pack 5 is pushed to the center. The inclined surfaces on both sides of the second support body 502 of the battery pack 5 are pushed to the center by the second clamping assembly. Through the cooperation of the first clamping assembly and the second clamping assembly, the two ends of the battery pack 5 are clamped to the center, so as to realize the center positioning of the battery pack 5 on the top of the carrying frame and ensure the stability of the battery pack 5 during the transfer to the battery cabinet.

[0048] In the third step, after the battery pack 5 is centered on the top of the carrier frame, the movable slider 3 is driven by the electric slide rail 2 to move to the middle position of the electric slide rail 2, and then the carrier frame and the battery pack 5 are synchronously driven to move to the middle position of the top of the moving seat 1, which is conducive to adjusting the center of gravity to the middle section of the moving seat 1, providing favorable conditions for the stability of the guide vehicle.

[0049] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, the bearing frame includes a bottom plate 6, a top plate and two side plates 9, the two side plates 9 are fixedly connected to both ends of the bottom plate 6, and the two side plates 9 are slidably plugged into the two movable sliders 3 respectively;

[0050] The top plate includes a first bearing plate 7 and two second bearing plates 8. The two second bearing plates 8 are located on both sides of the first bearing plate 7. There is a clearance space 11 between the second bearing plate 8 and the two first bearing plates 7. A fixing frame 10 is fixedly connected between the bottom of the first bearing plate 7 and the bottom plate 6.

[0051] A height adjustment component is provided at the bottom of the base plate 6 , and the height adjustment component is used to adjust the height of the base plate 6 .

[0052] It should be understood that the two clearance spaces 11 provide clearance spaces 11 for forklifts and other equipment to transfer the battery pack 5 to the top of the load-bearing plate. By setting a height adjustment component to first raise the bottom plate 6, the staff has enough space to observe the clearance spaces 11. Then, after installing the battery pack 5 on the top of the load-bearing plate, the height of the bottom plate 6 is lowered, thereby lowering the height of the entire load-bearing frame and the battery pack 5, which is beneficial to lowering the center of the entire guide vehicle and providing favorable conditions for the movement and stability of the guide vehicle.

[0053] like Figure 2 and Figure 4 As shown, in one embodiment, the height adjustment assembly includes:

[0054] A first motor 12, the first motor 12 is fixedly mounted on the top of the bottom plate 6;

[0055] A threaded sleeve 13, the threaded sleeve 13 is rotatably connected to the bottom of the base plate 6, and the top end is fixedly connected to the output end of the first motor 12;

[0056] The slide groove 14 is opened at the top of the moving seat 1 , and a supporting slider 15 is slidably arranged in the slide groove 14 . A threaded rod 16 is fixedly connected to the top of the supporting slider 15 , and the threaded rod 16 is threadedly connected to the inside of the threaded sleeve 13 .

[0057] It should be understood that when the height of the carrying frame needs to be raised, the first motor 12 is started, the first motor 12 drives the threaded sleeve 13 to rotate, the threaded sleeve 13 moves on the surface of the threaded rod 16, and then drives the bottom plate 6 to move, thereby achieving the adjustment of the height of the entire carrying frame;

[0058] Furthermore, when the carrying frame moves to any position, the supporting slider 15 will move to the corresponding position of the sliding groove 14 to avoid hindering the movement of the carrying frame.

[0059] like Figure 2 and Fig. 9 As shown, in one embodiment, the first clamping assembly includes:

[0060] A first mounting groove 17, the first mounting groove 17 is provided at the top of the bottom plate 6, a first linkage plate 18 is provided in the first mounting groove 17, the top of the first linkage plate 18 is slidably connected to the top of the second bearing plate 8 located above the first linkage plate 18, a first guide groove is provided on the surface of the first linkage plate 18, the first guide groove includes a first oblique groove 1801 and a first vertical groove 1802, a side surface of the first linkage plate 18 is fixedly connected to a first linkage rail 19, two first gas springs 20 are slidably provided in the first linkage rail 19, and the top ends of the two first gas springs 20 are fixedly connected to first limit pins 21;

[0061] Two first clearance grooves 22, which are provided on the top of the second supporting plate 8 above the first linkage plate 18 and are arranged in an eight-shaped shape. After the two first limiting pins 21 pass through the two first clearance grooves 22, they contact the two sides of the first support body 501 at the first end of the battery pack 5 respectively;

[0062] The first guide pin 23 is slidably disposed in the first inclined slot 1801 , and both ends are rotatably connected to the first traction frames 24 . The two first traction frames 24 pass through the first mounting slot 17 and are fixedly connected to the side wall of the movable slider 3 .

[0063] It should be understood that before installing the battery pack 5 on the top of the carrying frame, the height of the carrying frame is adjusted to a certain height by the height adjustment assembly. In the process of raising the carrying frame, the first guide pin 23 will move in the first inclined groove 1801 of the first guide groove, and the first guide groove will be pushed, so that the first linkage plate 18 drives the first linkage rail 19 to move, and the first linkage rail 19 synchronously drives the two first gas springs 20 to approach the side plate 9, and the two first gas springs 20 drive the two first limit pins 21 to move in the two first make way grooves 22 respectively, so as to provide space for the installation of the battery pack 5;

[0064] After the battery pack 5 is placed on the top of the upper supporting plate, the height of the supporting frame is adjusted to be lowered for reset through the height adjustment assembly. During the process of lowering the height of the supporting frame for reset, when the first guide pin 23 moves in the first inclined groove 1801, it will push the first linkage plate 18 to move and reset. The first linkage plate 18 will drive the first linkage rail 19 to move and reset, and then push the two first gas springs 20 and the two first limit pins 21 to move and reset, so as to clamp and position the inclined surfaces on both sides of the first support body 501 of the battery pack 5.

[0065] like Figure 2 , Figure 7 and Figure 8 As shown, in one embodiment, the second clamping assembly includes:

[0066] A second mounting groove 25 is provided at the top of the bottom plate 6. A second linkage plate 26 is provided in the second mounting groove 25. The top of the second linkage plate 26 is slidably connected to the top of the second bearing plate 8 located above the second linkage plate 26. A second guide groove is provided on the surface of the second linkage plate 26. The second guide groove includes a second oblique groove 2601 and a second vertical groove 2602. The side of the second linkage plate 26 is fixedly connected to a second linkage rail 27. Two second gas springs 28 are slidably provided in the second linkage rail 27. The tops of the two second gas springs 28 are fixedly connected to second limit pins 29;

[0067] The second guide pin 31 is slidably disposed in the second inclined slot 2601, and both ends are rotatably connected to the second traction frames 32. The two second traction frames 32 pass through the second mounting slot 25 and are fixedly connected to the side wall of the movable slider 3;

[0068] Two second clearance grooves 30 are opened on the top of the second supporting plate 8 above the second linkage plate 26 and are arranged in an eight-shaped shape. After the two second limit pins 29 pass through the two second clearance grooves 30 respectively, they contact the two sides of the second support body 502 at the second end of the battery pack 5 respectively.

[0069] It should be understood that before installing the battery pack 5 on the top of the carrying frame, the carrying frame is adjusted to a certain height by the height adjustment assembly. In the process of raising the carrying frame, the second guide pin 31 will move in the second inclined groove 2601 of the second guide groove, and the second guide groove will be pushed, so that the second linkage plate 26 drives the second linkage rail 27 to move, and the second linkage rail 27 synchronously drives the two second gas springs 28 to approach the side plate 9, and the two second gas springs 28 drive the two second limit pins 29 to move in the two second make way grooves 30 respectively, so as to provide space for the installation of the battery pack 5;

[0070] After the battery pack 5 is placed on the top of the carrying frame, the height of the carrying frame is adjusted to be lowered and reset through the height adjustment assembly. When the carrying frame is lowered and reset, the second guide pin 31 moves in the second inclined slot 2601, which pushes the second linkage plate 26 to move and reset. The second linkage plate 26 drives the second linkage rail 27 to move and reset, and then pushes the two second gas springs 28 and the two second limit pins 29 to move and reset, so as to clamp and position the inclined surfaces on both sides of the second support body 502 of the battery pack 5;

[0071] To further explain, in the process of installing the battery pack 5 on the guide vehicle, the height of the carrying frame is first raised by the height adjustment assembly to accommodate the battery pack 5, and the clamping limits of the first clamping assembly and the second clamping assembly are automatically cancelled to provide installation space. After placing the battery pack 5, the height of the carrying frame is lowered by the height adjustment assembly, thereby driving the battery pack 5 to lower its center of gravity. In the process of lowering the height of the carrying frame and the battery pack 5, the first clamping assembly and the second clamping assembly are used to automatically clamp the two ends of the battery pack 5, so that the battery pack 5 is centered on the top of the carrying frame.

[0072] like Figure 2 , Figure 3 and Figure 7As shown, in one embodiment, a mounting seat 33 is fixedly connected to the surface of the side plate 9 located at the second end of the carrying frame, a connecting shaft 34 is rotatably connected to the mounting seat 33, a connecting seat 35 is fixedly sleeved on the surface of the connecting shaft 34, a torsion spring 36 is fixedly connected between the connecting seat 35 and the mounting seat 33, a third gas spring 37 is fixedly connected to the top of the connecting seat 35, a connecting frame 38 is fixedly connected to the top of the third gas spring 37, a shielding cover 39 is fixedly connected to the end of the connecting frame 38, and the shielding cover 39 is used to shield the electrode 503 and the cooling joint 504 at the second end of the battery pack 5;

[0073] A gear 40 is also fixedly connected to the surface of the connecting shaft 34, and a linkage rack 41 is meshed at the bottom end of the gear 40. The linkage rack 41 passes through the side plate 9 and the bottom plate 6 and extends into the second mounting groove 25. A linkage block 42 that cooperates with the second guide pin 31 is fixedly connected to the end of the linkage rack 41, and a matching inclined groove 43 is opened at the top of the linkage block 42.

[0074] It should be understood that the electrode 503 of the battery pack 5 needs to be protected during the transfer process. If the electrode 503 collides with an external object, the electrode 503 will be damaged on the one hand, and on the other hand, if conduction occurs, a short circuit will occur, which will damage the battery. This embodiment can solve the above problems. The specific protection method is as follows:

[0075] Step 1: When the carrying frame is lifted, the second guide pin 31 will be away from the matching inclined slot 43 on the linkage block 42, which indirectly cancels the traction on the linkage rack 41. Under the action of the torsion spring 36, the connecting seat 35 will flip over. The connecting seat 35 will be synchronously flipped through the third gas spring 37, the connecting frame 38 and the shielding cover 39, and then away from the top of the carrying frame.

[0076] Step 2, after the battery pack 5 is installed on the top of the carrying frame, the carrying frame is lowered by the height adjustment assembly for reset.
